freshwater accounts for only about ______ percent
Answers
Answer:
Fresh water accounts for only about 0.3%.
Answer:
Freshwater accounts for only about 2.7 percent.
Explanation:
Oceans make up 97.3% of all water sources on Earth. Thus, the share of fresh water sources is only 2.7%. Of all fresh water sources, only 2.9% is available to us in the form of fresh water lakes, rivers and groundwater.
The total water volume on Earth is estimated at 1.386 billion km³ (333 million cubic miles), of which 97.3% is salt water and 2.7% fresh water. Only 0.3% of fresh water is in liquid form on the surface.
Extra information:Because the oceans, which cover approximately 71% of Earth's surface, reflect blue light, Earth appears blue from space and is often referred to as the Blue Planet and the Pale Blue Dot. Liquid freshwater, such as lakes and rivers, covers about 1% of Earth's surface and together with Earth's ice sheets make up 75% of Earth's surface by area.
