Water resources.

The total amount of water on the earth is about 1.4 billion cubic kilometers, of which fresh water accounts for only the total water, and it is mainly distributed in the ice and snow of the north and south poles. At present, only the underground desalient level, lake freshwater and riverbed water can be directly used by human beings, and the sum of the three accounts for about the total amount of water on the earth. China's total water resources are about 2,812.4 billion cubic meters, of which groundwater is about 870 billion cubic meters.

The water resources are about 2,700 cubic meters, which is 25% of the world's per capita share, ranking 88th in the world. China's freshwater accounts for 8% of the world's freshwater, and its per capita share is 30% of the world's per capita share. For example, the north of the Yangtze River, which accounts for more than half of the country's land area and 64% of the country's cultivated land, accounts for only 18% of the country's water resources, especially in North China, where the per capita is less than 1 6 percent of the national average.

I don't know if I can help you drip.

Freshwater is distributed in: glaciers, groundwater, atmospheric water, biological water.

Brackish water: ocean, underground brackish water, lake brackish water.

Ocean water accounts for glacier water and groundwater together and the rest is for other water bodies

Water is distributed in ocean, terrestrial, air, and organisms

Water in nature exists in three forms: solid, liquid and gas, and liquid water includes: groundwater, surface water, runoff, ocean, wetland, etc.

Solid water: glaciers, snow, etc.

Gaseous: Water vapor.

Fresh water in the mountains and at the bottom of the sea. Believe it or not.

Yan Yan in**! You're at home, someone's not, what are you doing?

Water on Earth is found in oceans, rivers, glaciers, the atmosphere, and underground. About the water on Earth is found in the oceans, lakes account for saltwater, and fresh water accounts for the total amount of water in the world. Freshwater is glaciers and permanent snow cover, groundwater, distributed in rivers, lakes and the atmosphere. <

Water on Earth is found in oceans, rivers, glaciers, the atmosphere, and underground. About the water on Earth is found in the oceans, lakes account for saltwater, and fresh water accounts for the total amount of water in the world. Freshwater is glaciers and permanent snow cover, groundwater, distributed in rivers, lakes and the atmosphere.

The water on the earth is occupied by oceans, polar icebergs, underground tribes, lakes and rivers, and cloudsWater vaporOccupy.

The total amount of water that the Earth has is about 13.6 billion tons, of which about 100 billion tons of salty seawater is there. Due to salinity issues, seawater cannot be used as a water source by life on land. The distribution of water on Earth is roughly as follows:

The sea bureau occupies the spring ocean, the polar icebergs, the groundwater, the lakes and rivers, and the water vapor in the clouds.

Fresh water on land comes from the sky. The sea water evaporates in the sun, the salt remains in the sea, and the fresh water evaporates into the sky, forming clouds. The clouds are blown over the land by the wind, condense and fall to the earth.

In this way, rivers, lakes and wetlands on land are formed, which are the source of fresh water for life on land.

The use of water: firstly, water is a substance necessary for the normal metabolism of the human body, accounting for about 70% of the normal human body weight; Water regulates the climate, and without it, the Earth's climate might not be suitable for human life. Water is also important for agriculture, with which all kinds of crops can be irrigated and grow normally; In industry, light industry Zhaochun industry.

Heavy industry, energy industry, etc., all require the use of water resources.

Water is needed everywhere in life, such as cooking, washing, etc.

Water on Earth is found in oceans, rivers, glaciers, the atmosphere, and underground.

Ninety-six .53 per cent of the earth's water is found in the oceans, 0.94 per cent of lakes are saltwater, and fresh water accounts for 2.53 per cent of the world's total water volume. 68.7 percent of fresh water is glaciers and permanent snow cover, 30.01 percent is groundwater, and 1.29 percent is distributed in rivers, lakes and the atmosphere.

Water on Earth is distributed in oceans, rivers, glaciers, the atmosphere, and underground.

The amount of water that the Earth has is enormous, with a total of nearly 1.4 billion cubic kilometers. Among them, the vast majority of water is gathered in the ocean, accounting for the total amount of water on the earth, and it covers more than 70% of the earth's surface; The water in glaciers, permafrost, and snow cover is in a solid state, occupying; Underground soil and rock formations containing multiple layers of ground carefully disturbed sewerage, occupied;

The remaining amount of water is scattered in lakes, rivers, the atmosphere and living organisms. Lakes, inland seas, and rivers occupy 250,000 cubic kilometers (10,000 cubic kilometers) of fresh water, while atmospheric water vapor occupies 130,000 cubic kilometers (1,000,000 cubic kilometers).

It can be said that from the sky to the ground, from the land to the sea, there is a world of water everywhere. There is some truth in calling our earth a water balloon for this reason.

Water resources.

In terms of the distribution of water resources on all continents, Asia has the largest annual runoff, followed by South America, North America, Africa, Europe, and Oceania. From the perspective of per capita runoff, the total amount of river runoff in the world is about 10,000 cubic meters per person. Among the continents, Oceania has the largest per capita runoff, followed by South America, North America, Africa, Europe, and Asia.

The distribution characteristics of water resources in China are as follows: the distribution is concentrated in the year, and the change is large in the year; The water resources of the four basins of the Yellow River, Huai River, Haihe River and Liaohe River are small, and the water volume of the Yangtze River, Pearl River and Songhua River basins is large. The arid areas of the northwest inland have a shortage of water, while the southwest region has abundant water.

The total amount of water resources is large, but the per capita share is small, and China's total water resources rank fourth in the world. The per capita share is only 1 4 of the world average, which is about 1 2 of Japan's Kuanyudan, 1 4 of the United States, and 1 12 of Russia.

The vast majority of the Earth's water is found in the oceans.

The total amount of water on Earth is about 136,000 cubic kilometers. Among them, 132,000 cubic kilometers of ocean, accounting for; Ice caps and glaciers 29.2 million cubic kilometers, occupying; 10,000 cubic kilometers of groundwater, occupying; 10,000 cubic kilometers of rivers, occupying.

10,000 cubic kilometers of freshwater lakes, occupying; 10,000 cubic kilometers of saltwater lakes and inland seas, pretending to occupy sections; 10,000 cubic kilometers of soil water, occupying; Atmospheric water 10,000 cubic kilometers, accounted for. Therefore, the water on Earth is mostly distributed in the oceans.

Water is one of the most common substances on the earth, an important resource for the survival of all life, including inorganic compounds, and human beings, and is also an important part of the reputation of living organisms. Although it is present in small quantities in air, it is an important component of air.

Water's**

There are many different understandings of water on the earth, each with its own truth, and the current representative ones are the exogenous theory and the endogenous theory.

The exogenous theory holds that the water on Earth comes from outside the Earth. One of the candidates for exotic water sources is comets and water-rich asteroids. Comets, known as "dirty snowballs", are composed of water and interstellar dust, and comets hitting the Earth bring a large amount of water.

The Endosource theory holds that the water on Earth comes from the Earth itself. The Earth was formed by fractionation, collapse, and condensation of the original solar nebula gas and dust. After condensing, these stars continue to gather to form the embryos of the planets, and then further increase and grow to form the original Earth.

When the earth originated, the material that formed the earth contained water.

Most of the earth's water is distributed in oceans and rivers, including the Pacific Ocean, the Indian Ocean, the Atlantic Ocean, the Yangtze River, the Nile River, etc.

Water is a colorless and odorless liquid, and 72% of the earth's surface is covered by water, such as oceans, rivers, lakes, etc. Although water is present in small amounts in the air, it is an important component of the air. Earth's natural water resources include river runoff, groundwater, snow and glaciers, lake water, swamp water, and seawater.

The vast majority of the Earth's water is found in the oceans. The oceans contain more than 1.35 billion cubic kilometres of water, about 97 per cent of the planet's total water, and only 2 per cent of it is available for human consumption.

The earth's surface is divided by major landmasses into vast bodies of water called oceans, with a total area of about 100 million square kilometers, accounting for about the earth's surface area.

71% of the water with an average water depth of about 3795 meters. The oceans contain more than 1.35 billion cubic kilometres of water, about 97 per cent of the planet's total water, and only 2 per cent of it is available for human consumption.

The four major oceans on Earth are the Pacific Ocean and the Atlantic Ocean.

India is suspicious of the Arctic Ocean.

Most of them are bounded by terrestrial and submarine topographic lines. So far, only 5% of the seabed has been explored, and 95% of the seabed is unknown.

The vast majority of the Earth's water is found in the oceans. The Ocean contains more than 1.35 billion cubic kilometers of water, accounting for about 97% of the total water on the planet, and only 2% of it can be used for human drinking.
