The amount of time it takes Earth to rotate on once on its axis would be 24 hours.
Answer:
Most of Earth's freshwater is locked in ice
Over 96% of Earth's water is saline (salty) and found in the ocean. Only a little over 3% of Earth's water is fresh. Most of that freshwater (68.7%) is frozen in glaciers and ice caps.
Explanation:
Answer:
They are youngest close to the ridges,
Explanation:
At the ocean ridges, there is divergence at their margins.
Therefore, new materials upwell from the mantle below to the surface.
- The basaltic materials cools and solidifies at the margin.
- This action forces the old lithosphere backwards as the plate pulls away.
- At the margin of the ridge, the rocks are younger.
- Away from the margin, the crust begins to grow older.
So, at the margin the age of the rocks are more younger than those away from the margin.
The largest canyons and deepest valleys were created by moving water.
