The problem of the geographical water cycle, the impact of the water cycle on the geographical envir

Water is constantly moving and transforming in the vast system of the water cycle, so that the water resources are constantly renewed. The water cycle maintains the dynamic balance of water worldwide. The water cycle carries out energy exchange and material transfer.

Land-based runoff transports sediment, organic matter and salt into the ocean. It is of great significance for climate regulation to absorb, transform and transmit surface solar radiation and alleviate the contradiction of heat budget imbalance between different latitudes. <

1. Water is constantly moving and transforming in the huge system of water and circulation, so that water resources are constantly renewed.

6. The freshwater resources of the land are constantly replenished and renewed, the surface shape is changed, and the water cycle is continuously transported and converted in the four major circles.

1. Water in the water cycle.

This vast system is constantly moving and transforming, so that water resources are constantly renewed.

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

3. The water cycle carries out energy exchange and material transfer. Land-based runoff transports sediment, organic matter and salt into the ocean. Solar radiation to the surface.

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

4. Cause erosion, transportation, accumulation and other external forces such as auspicious effects, and constantly shape the surface form.

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

6. Make land freshwater resources.

It is constantly replenished and renewed, changing the surface morphology, and the water cycle is constantly transporting and converting energy in the four major circles.

1) Changing surface runoff - the most important way of impactHuman activities such as irrigating rivers and lakes, building reservoirs, transferring water across river basins, filling rivers and reroads, and enclosing lakes to create fields have greatly changed the natural distribution of surface runoff.

2) Affect underground runoff.

The development and utilization of groundwater resources and the construction of underground projects in local areas have an unavoidable impact on underground runoff, such as artificial recharge of groundwater in the rainy season, pumping groundwater for irrigation, and the construction of urban underground railways to destroy the geological structure and change the seepage direction of groundwater.

3) Affecting local atmospheric precipitation, such as artificial rainfall.

4) Affect evaporation, such as afforestation, and the construction of reservoirs can increase the amount of water vapor in local areas.

The geographical significance of the water cycle is fivefold:

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. Land-based runoff transports sediment, organic matter and salt into 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: 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 of great significance for the evolution of the Earth's surface structure and for the sustainable development of human beings.

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 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. 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.
