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.

The correct option is;

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

Explanation:

The Karoo Supergroup that formed hundres of millions of year ago covered the most part of South Africa. The Tillite debris from melting glaciers, in Dwyka Tillite are located at the bottom layers of the Karoo Supergroup, which is an indication that millions of years ago, South Africa was under extensive glacier coverage formed during the movement of the continent past the South Pole

The eventual arrival of the continent to temperate regions away from the South Pole resulted in the melting of the glaciers from which a huge swamp was formed.
