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.

Temperature decreases with altitude in two of Earth's atmospheric regions: the troposphere and the mesosphere. The troposphere is the region closest to the ground, and the mesosphere is just above the ozone layer.
Explanation:
Answer:
a) explained the appearance of the sun's rotation with a theory of earthly rotation.
Explanation:
Nicolaus Copernicus gave the model of the solar system , named as the Copernican heliocentrism , in the year 1543 .
According this model, the Sun is placed stationary at the very center of the universe and all the planets are moving in a defined path , with uniform speed .
The model gave modern astronomy a kick start .
Hence , from the question,
The correct statement is a) explained the appearance of the sun's rotation with a theory of earthly rotation.
