The answer is B, because it is measuring the rainfall over a ling period of time
Answer:
Oceans = > 97 percent of Earth's water.
Glaciers = > 70% of Earth's freshwater
River = > Powered by gravity
Groundwater = > 100 times more water than all rivers and lakes
97% of the water on Earth is not drinkable as it is salt-water in oceans.
Of the 3% that is freshwater, Glaciers make up about 70% which means that we don't have access to a significant amount of freshwater either.
Of the available freshwater to us, groundwater comprises 98% which enables it to be 100 times more than all rivers and lakes.
Rivers are powered by gravity in that they flow from areas of higher elevation to areas of lower elevation as gravity pulls it downwards.
Wind erosion is so harmful because it removes the most fertile part of the soil.
So, the answer is option 4. It removes the most fertile part of soil.
Happy Studying!
Answer:
All resources mentioned in the list are <em>non-renewable</em> (cannot be replenished/once they're gone, they're gone.)
Explanation:
According to the<em> </em><em>National</em><em> </em><em>Geography</em><em> </em><em>Society</em><em>:</em>
<em> </em>"There are four major types of nonrenewable resources: <em>oil, natural gas, coal, and nuclear energy</em>. Oil, natural gas, and coal are collectively called fossil fuels. Fossil fuels were formed within the Earth from dead plants and animals over millions of years—hence the name “fossil” fuels."
