This pie chart displays the makeup of Earth's water. Which sentence is true about Earth's water, based on the data in the pie chart?
Over 30% of fresh water humans use comes from lakes and rivers
Humans use a much greater percentage of salt water than fresh water
Fresh water makes up 2.5% of the water on Earth so it should be conserved
Most of Earth's total water is frozen in ice glaciers, which are made of salt water
Less than 3% of the Earth's water supply is fresh water. Only about 0.3% of this supply is surface water, found in rivers, lakes, and swamps. This pie chart shows how this small percentage of surface water is distributed. Based on the data shown, which statement is true?
The majority of Earth's rivers and swamps are found in North America and Africa
The North American Great Lakes is Earth's third-largest fresh surface water source
The North American Great Lakes and Lake Baikal hold 50% of Earth's fresh surface water
The amount of fresh surface water in swamps and rivers is equal to that of Lake Baikal
The water cycle describes the movement of water on Earth. About 96% of water on Earth is the salt water found in oceans. The remaining 4% is fresh water. Where would the majority of the fresh water on Earth be found?
groundwater and aquifers
swamps and wetlands
ice caps and glaciers
lakes and rivers
Fresh water is water that is not salty. The graph below shows three ways fresh water is found on Earth: as ice, as groundwater, and as water above ground.
Asia
Africa
Australia
Antarctica
The chart shows the distribution of fresh water on Earth. Most of the fresh water on Earth is
highly polluted
in the frozen state
used for agriculture
purified for drinking
