What is an area of land in which all freshwater converges into the largest stream, ultimately draining into the largest body of water?
watershed
. The area of land drained by a river and all its tributaries is that river’s watershed, which is also called a drainage basin. You just studied 35 terms!
What percentage of the Earth is comprised of open ocean?
More than
99 percent
of Earth’s inhabitable space is in the open ocean.
Where is the largest supply of liquid freshwater?
what is the largest source of liquid fresh water on the planet?
ground water
.
What refers to all liquid fresh water located above ground?
surface water
. all liquid fresh water located above ground. groundwater.
What percentage of the water on earth is fresh water available for drinking?
Only about three percent of Earth’s water is freshwater. Of that, only about
1.2 percent
can be used as drinking water; the rest is locked up in glaciers, ice caps, and permafrost, or buried deep in the ground. Most of our drinking water comes from rivers and streams.
Where is the most freshwater on Earth?
| Rank Country Freshwater (Kilometers Cubed) | 1 Brazil 8,233 | 2 Russia 4,508 | 3 United States 3,069 | 4 Canada 2,902 |
|---|
What is the greatest reservoir of fresh water in the world?
About three-quarters of Earth’s freshwater is stored in glaciers. Therefore,
glacier ice
is the second largest reservoir of water on Earth and the largest reservoir of freshwater on Earth!
Which is the biggest between sea and ocean?
Area. Oceans cover 71% of the Earth’s surface, and contain 97 percent of the planet’s water.
The Pacific Ocean
is the largest ocean covering an area of 64,186,000 square miles and the Mediterranean Sea is the largest sea with an area of 1,144,800 square miles.
What are the 3 zones of the ocean?
There are three main ocean zones based on distance from shore. They are
the intertidal zone, neritic zone, and oceanic zone
.
What are the 4 ocean zones?
Like ponds and lakes, the ocean regions are separated into separate zones:
intertidal, pelagic, abyssal, and benthic
. All four zones have a great diversity of species. Some say that the ocean contains the richest diversity of species even though it contains fewer species than there are on land.
What is the surface of the water called?
Surface water is
any body of water above ground
, including streams, rivers, lakes, wetlands, reservoirs, and creeks. … Water that seeps deep into the ground is called groundwater. Surface water and groundwater are reservoirs that can feed into each other.
What is movement of the surface of water?
Surface movement includes rivers, streams, creeks, lakes, ponds, and human-made “flood” control. All surface water is
trying to reach sea level due to gravity
. As water flows in channels, the streambed and banks of the channel will resist the flow of water.
What are the surface source of water?
Surface water originates mostly from
rainfall
and is a mixture of surface run-off and ground water. It includes larges rivers, ponds and lakes, and the small upland streams which may originate from springs and collect the run-off from the watersheds.
Where is 70% of Earth’s freshwater?
Our freshwater is locked up in
the Antarctic Ice Sheet
. About 71% of the Earth is covered in water. Most of that is in oceans, rivers, and lakes, but some is frozen in the Earth’s two ice sheets.
Why is only 1% of the earth’s water available to us?
Over 97 percent of the earth’s water is found in the oceans as salt water. Two percent of the earth’s water is stored as fresh water in glaciers, ice caps, and snowy mountain ranges. That leaves only one percent of the earth’s water available to us for
our daily water supply needs
.
Is Australia water rich or poor?
Australia’s Water Supply
Australia is also the driest continent inhabited by humans, with very
limited freshwater sources
. Despite the lack of freshwater, Australians use the most water per capita globally, using 100,000L of freshwater per person every year.
