Answer:
a. A convergent boundary is where plates come together and a divergent boundary is where they move apart from each other.
Explanation:
The surface of the earth is made up of a series of different-sized tectonic plates. Over time, these plates move relative to one another, causing earthquakes and volcanic activities.
A convergent boundary is created when two plates come together. The force of this collision can push the edges of the plates into ocean or mountain floors, resulting in a series of volcano.
A divergent boundary on the other hand, is created when a plate moves apart from another. Usually, an earthquake will occur at this boundary and magma will erupt to the surface of the earth crust.
Antarctica would have flora and fauna very different from Sahara - so we can exclude this option. Also, Sahara doesn't have ice sheets - so we can exclude option c too.
The correct answer is d- deserts are usually defined in their relatively low level of precipitation.
