Question

the hydrosphere refers to the total amount of water on earth, including liquid, gas, and solid forms. which is one way the hydrosphere has been impacted by the movement of the continents over time?
○ glaciers that once covered south africa have melted and can no longer form.
○ all of the continents have fewer coastal areas than they did millions of years ago.
○ land masses near the equator have more glaciers now than they did millions of years ago.
○ the poles that were once covered by glaciers are now surrounded by warm, tropical waters.

Explanation:

Continental drift moved South Africa from a polar/subpolar region (where glaciers could form) to its current temperate, southern hemisphere location. This shift in continental position eliminated the cold conditions needed for glaciers to persist or form there, directly linking continental movement to a change in the hydrosphere's solid (glacial) water component. The other options are incorrect: coastal area extent has not uniformly decreased, equatorial land masses do not have more glaciers now, and the poles remain cold with polar (not tropical) waters.

Answer:

Glaciers that once covered South Africa have melted and can no longer form.
