US and Canadian researchers recently calculated the total amount of the world's groundwater and estimated that it is equivalent to a lake 180 metres deep covering the entire Earth. This makes groundwater the largest active freshwater resource on the planet.
What is the largest reservoir for nitrogen?
the atmosphere By far the largest reservoir of total nitrogen on Earth is the dinitrogen gas (N2) in the atmosphere (Table 4.1). N2 is also the major form of nitrogen in the ocean. The most abundant form of nitrogen in soils and marine sedi- ments is organic nitrogen, produced by biological processes.
Where is the largest reservoir of the water cycle?

What is the largest reservoir for carbon?
the deep-ocean The largest reservoir of the Earth's carbon is located in the deep-ocean, with 37,000 billion tons of carbon stored, whereas approximately 65,500 billion tons are found in the globe. Carbon flows between each reservoir via the carbon cycle, which has slow and fast components.
What is the second largest reservoir of water on Earth quizlet?
what is the 2nd largest reservoir in the hydrosphere, and where is it located? Glacial ice is the second largest reservoir of water in the hydrosphere. Most glacial ice occurs in Antarctica and Greenland.
Where is the world’s largest reservoir?
Akosombo Dam, Ghana Constructed on the Volta River, the dam creates the 8,500km2 Lake Volta, which is the world's biggest reservoir by surface area. The lake impounds a mammoth 144 billion cubic metres of water.
What is the largest reservoir of phosphorus?
ocean sediments The ocean sediments are therefore by far the greatest reservoirs of phosphorus.
What is the reservoir of phosphorus?
Explanation: The reservoir of phosphorus in ecosystems is rock, where it is bound to oxygen in the form of phosphate. As phosphate-rich rocks are exposed and eroded, rainwater dissolves the phosphate. Dissolved phosphate is abosrbed through the roots of plants.
What is the largest reservoir of nitrogen?
the atmosphere By far the largest reservoir of total nitrogen on Earth is the dinitrogen gas (N2) in the atmosphere (Table 4.1). N2 is also the major form of nitrogen in the ocean.
Which is the largest reservoir of oxygen?
By far the largest reservoir of Earth's oxygen is within the silicate and oxide minerals of the crust and mantle (99.5% by weight). The Earth's atmosphere, hydrosphere, and biosphere together hold less than 0.05% of the Earth's total mass of oxygen.
Where is the largest reservoir for water in the hydrologic cycle?
the oceans The largest reservoir by far is the oceans, which hold about 97% of Earth's water. The remaining 3% is the freshwater so important to our survival, but about 78% of that is stored in ice in Antarctica and Greenland.
What is the second largest water reservoir in the hydrosphere and where is it located?
What is the second largest reservoir in the hydrosphere, and where is it located? Glacial ice is the second reservoir in the hydrosphere, most of which covers much of Antarctica and Greenland. Ice and snow make up 2.1% of the water in the hydrosphere.
Which is the largest reservoir in India?

|---|---|---|
| Maharashtra | Koyna River | Koyna Dam |
| Madhya Pradesh | Narmada | Indira Sagar |
| Telangana | Godavari | Sriram Sagar |
| Andhra Pradesh and Telangana | Krishna | Nagarjuna Sagar |
Which is the largest reservoir of nitrogen?
atmosphere The largest reservoir of nitrogen on Earth is N2 gas present in the air. The air in Earth's atmosphere is composed of around 78% nitrogen gas.
What is the largest reservoir of sulfur?

Where is groundwater found?
Groundwater is found in two zones. The unsaturated zone, immediately below the land surface, contains water and air in the open spaces, or pores. The saturated zone, a zone in which all the pores and rock fractures are filled with water, underlies the unsaturated zone.
