The geographical significance of the water cycle is discussed.

The water cycle connects the atmosphere, hydrosphere, lithosphere and biosphere through various links and exchanges energy between them; Water carries dissolved substances and sediment during movement, causing substances to migrate; Through the movement of the water cycle, various water bodies are transformed into each other, so that the water resources form a unified system that is constantly updated.

Water is the medium of all nutrients, and the cycle of nutrients and the water cycle are inextricably linked;

Water is a good solvent for substances and plays a role in energy transfer and utilization in the ecosystem;

Water is one of the drivers of geological change, the loss of mineral elements in one place, and the deposition of mineral elements in another place is often done through the water cycle.

The hydrosphere on Earth is a never-ending dynamic system. Driven by solar radiation and the Earth's gravity, water moves continuously between the components of the hydrosphere, forming a global cycle between land and sea (macrocycle), and connecting various water bodies so that they can exist for a long time. The exchange of water between the sea and the land is the main thread of this cycle and is of the greatest significance.

Under the action of solar energy, the water on the surface of the ocean evaporates into the atmosphere to form water vapor, which moves with the atmospheric circulation, and part of it enters the land airspace, forming precipitation such as rain and snow under certain conditions. When atmospheric precipitation reaches the surface, it is converted into groundwater, soil water, and surface runoff, which eventually returns to the ocean, thus forming a dynamic cycle of freshwater. This part of the water is easy to be used by human society and has economic value, which is exactly what we call water resources.

The water cycle is the "link" and "regulator" that connects the earth's circles and various water bodies, which regulates the energy between the earth's circles and plays an important role in the cold and warm climate change. The water cycle is the "sculptor" that shapes the colorful image of the surface through erosion, transport and accumulation. The water cycle is the "conveyor belt", which is a powerful driving force for the migration of surface materials, and the main carrier.

What's more, through the water cycle, the ocean continuously delivers fresh water to land, replenishing and renewing freshwater resources on new land, making water a renewable resource.

Hope...

The water cycle plays an important role in the global redistribution of water and heat, and this interaction occurs in conjunction with the atmospheric cycle, which affects the main aspects of a region's climate, such as water showers and temperature.

The water cycle acts as a "transport belt" of matter, and is also a powerful driving force for the mechanical transport of the lithospheric surface and the migration of inorganic and organic chemical elements in the natural geographical environment.

In the process of water cycle, various normal landforms and rivers, groundwater, lakes and so on are generated.

The water cycle is also the basic condition for biological organisms to sustain life activities and the entire biosphere to form a complex hydrocolloid system, which plays a role as a link between the organic and inorganic worlds.

In short, the water cycle is like the "blood circulation" of the natural geographical environment, which communicates the material exchange of the various basic circles and promotes the occurrence of various connections. The water cycle process plays the role of hydrological process, climatic process, topographic process, soil process, biological process and geochemical process.

As for the role of landforms in the geographical environment, I really won't say. Because the landscape is a pre-existing state, not a process, what is the role of a state? I can only say about the formation of the landform:

The formation of landform is the result of the comprehensive effect of internal and external geological processes on the earth's crust. The internal geological action causes the ups and downs of the land surface, which controls the distribution of sea and land corridors, and the regional configuration of mountains, plateaus, basins and plains, and determines the tectonic framework of the landform. The geological processes of external forces (flowing water, wind power, solar radiation energy, growth and activity of the atmosphere and organisms) have continuously weathered, eroded, transported and accumulated the surface materials of the earth's crust through various ways, thus forming various forms of modern ground.

Water cycle. There are five aspects of geographical significance:

1. Water is constantly moving and transforming in the huge system of the water cycle, so that water resources are constantly renewed (the so-called renewal determines that water is a renewable resource to a certain extent.

2. The water cycle maintains the dynamic balance of global water.

3. The water cycle carries out energy exchange and material transfer. Terrestrial runoff transports sediment, organic matter and salts to the ocean; Solar radiation to the surface.

Absorption, transformation, and transmission to alleviate the contradiction of heat budget imbalance between different latitudes are of great significance for climate regulation.

4. Cause erosion, transportation, accumulation and other external forces, and constantly shape the surface shape.

5. The water cycle can have an impact on the quality of the soil.

Significance of the water cycle: The water cycle has been regarded as a dynamic and ordered system. According to the system analysis, each link of the water cycle is a component of the system, and it is also a subsystem.

The subsystems are interconnected with each other in a certain relationship, which is achieved through a series of inputs and outputs.

For example, the output of precipitation from the atmospheric subsystem becomes the input of the land basin subsystem, which in turn becomes the input of the ocean subsystem through its output runoff. The above water cycle subsystems can also be subdivided into a number of more sub-systems.

The water cycle is one of the most important material cycles on the earth, which realizes the migration and conversion of water, energy and biochemicals in the earth system, and constitutes a global continuous and orderly dynamic system. The water cycle connects the two major systems of sea and land, shapes the surface morphology, restricts the balance and coordination of the earth's ecological environment, and continuously provides regenerative freshwater resources.

Therefore, the water cycle is essential for the evolution of the Earth's surface structure and for the sustainable development of human beings.

are significant.

1. The water cycle profoundly affects the formation, evolution and development of the earth's surface structure.

2. The essence of the water cycle is the transmission process of matter and energy.

3. The water cycle is the link between land and sea.

4. The water cycle is the sum of the continuous renewal of various water bodies in the earth system, which makes water a renewable resource rooted in the changes of human society and history.

The process of water circulation is actually relatively simple, that is to say, the water on the ground is then illuminated by the sun, he rises into the air, and forms clouds, and finally accumulates to a certain extent and then becomes water and falls on the ground, which is generally called rainfall, after the rain falls to the ground, it turns into water on the ground, and then rises by the sun's light, so it is said that the cycle goes back and forth, then its geographical significance is to say that our entire ecosystem has been created through the water cycle. All of our biological systems need water to grow, so the water cycle is a material activity that is decisive for our geography.

The geographical significance of the water cycle: water is constantly moving and transforming in the huge system of the water cycle, so that the water resources are constantly renewed (the so-called renewal, to a certain extent, determines that water is a renewable resource).

Geographical significance. 1. Water is constantly moving and transforming in the huge system of the water cycle, so that water resources are constantly renewed (the so-called renewal determines that water is a renewable resource to a certain extent.

2. The water cycle maintains the dynamic balance of global water.

3. The water cycle carries out energy exchange and material transfer. Terrestrial runoff transports sediment, organic matter and salts to the ocean; It is of great significance for climate regulation to absorb, transform and transmit solar radiation on the surface and alleviate the contradiction of heat budget imbalance between different latitudes.

4. Cause erosion, transportation, accumulation and other external forces, and constantly shape the surface shape.

5. The water cycle can have an impact on the quality of the soil.

Significance of the water cycle: (1) Maintain the dynamic balance of global water bodies; (2) to promote global energy exchange and material transfer; (3) shaping the surface morphology; (4) It has the effect of renewing and purifying terrestrial water resources.

Water is constantly flowing and changing shape on the earth. The wind and sun cause the water in the rivers, lakes and seas to evaporate and rise into the blue sky. Water from the surface of animals and plants can also enter the atmosphere through respiration and evaporation.

Water vapour in the atmosphere and clouds cools and returns to the ground as rain, snow, and hail. Water in nature is constantly circulating.

The geographical significance of the water cycle: first of all, it maintains the dynamic balance between the various water bodies on the earth, so that the freshwater resources are constantly renewed.

Secondly, the water cycle promotes the movement of matter and energy exchange in nature, which has a profound impact on ecology, climate, and landform.

Significance of the water cycle:

1. Water is constantly moving and transforming in the huge system of the water cycle, so that the water resources will not be broken and renewed.

2. Maintain the dynamic balance of global water.

3. Carry out energy exchange and material transfer.

4. Cause erosion, transportation, accumulation and other external forces to shape the surface shape.

5. It has an impact on the quality of the soil.

1. The process of the water cycle (1) The concept of the water cycle.

The water cycle refers to the process of continuous movement of water in nature in the hydrosphere, atmosphere, lithosphere, and biosphere through evaporation (transpiration), water vapor transport, precipitation, infiltration, runoff, and other links.

b) Classification of the water cycle.

Nature's water cycle is going on all the time. According to the spatial scope of occurrence, the water cycle can be divided into inter-land circulation, intraterrestrial circulation, and intra-marine circulation.

1.Circulation between land and sea.

The land-sea cycle refers to the water cycle that occurs between the ocean and the land.

The water on the surface of the ocean is evaporated into water vapor Water vapor is transported to the air and is transported by air currents over the continent Part of the water vapor condenses under appropriate conditions to form precipitation Precipitation flows on the surface to form surface runoff; Infiltrates into the ground to form underground runoff Surface and underground runoff collect back into the ocean. This cycle, also known as the Great Cycle, moves through which land water is continuously replenished and water resources are regenerated.

2.Intraterrestrial circulation.

The terrestrial internal circulation is the water on the land, which is partially or completely evaporated by the ground and water surface and transpiration of plants, forming water vapor, which is carried over the land by the air current, cools and condenses to form precipitation, and still falls on the land. Terrestrial internal circulation also plays a role in the renewal of water resources.

3.Offshore internal circulation.

The internal circulation of the sea is that the water on the surface of the sea evaporates to form water vapor, which enters the atmosphere and condenses over the ocean, forming precipitation, and then falling to the sea surface.

2. The significance of the water cycle.

1) Maintain the dynamic balance of global water volumes.

The water cycle organically links the atmosphere, hydrosphere, lithosphere and biosphere, so that the water bodies on the Earth are in a state of constant renewal, thus maintaining the dynamic balance of global water volume. For a given period of time, the world's ocean, terrestrial and atmospheric water will not increase or decrease.

2) The main link between land and sea and the late dissipation system.

Surface runoff continuously transports large amounts of sediment, organic matter and inorganic salts into the ocean.

and iii) to regulate the global heat balance.

The water cycle plays a role in the absorption, transformation and transmission of solar radiation reaching the surface, which alleviates the contradiction of heat budget imbalance in different latitudes.

4) Shaping the surface morphology.

Precipitation and surface runoff continue to shape the shape of the land's surface.

Answer]: a, b, c

The stem emphasizes the geographical significance of this feast of the water cycle. A, C is wrong. Item B is the physical meaning of the water cycle nuclear state, not the geographical meaning of Senyin. Therefore, ABC is chosen.

1. Balance renewal:

In the water cycle, water is constantly moving and transforming, so that the various water bodies on the earth are in a state of continuous renewal, which maintains the dynamic hail mill balance of global water;

2. Migration and exchange role:

The water cycle is one of the most active energy exchange and material transfer processes on the earth, and the water cycle plays a role in the absorption, transformation and transmission of surface solar radiation energy, alleviating the contradiction of heat budget imbalance at different latitudes.

3. Influence shaping:

The water cycle also affects the global climate and ecology, and is the most dynamic cycle movement in nature, constantly shaping the surface of the earth. The surface of the Loess Plateau is fragmented and fragmented, which is a strong evidence that the Yellow River shapes the surface morphology.
