B. False. Deserts are NOT only found near the equator. The reason for that is because some deserts are dry and hot, though, some deserts are cold, cold places for example the arctic. Tundra's are also cold, but they are deserts.
Desert is an area where rainfall is very little. Deserts are terrestrial ecosystems that are dominated by certain flora and fauna and are characterized by a dry climate with very little rainfall of 250 mm in a year.
Based on its astronomical location, this desert is found at 20º to 30º North Latitude and South Latitude which starts from the Atlantic Coast region in Africa to the central Asian region. Throughout this area there are the widest deserts in the world, namely the Sahara Desert, the Gobi Desert, and the Arabian Desert.
The equator is at a latitude of 0º to 23.5º so that the location of the desert is not located in the tropics alone but in subtropical climates and temperate climates.
The reason why the continental crust differs from the oceanic crust is much different in its compositions. The continental crust is thin and less dense , is made of sedimentary and metamorphic rocks than the oceanic crust and is made of lighter elements. The tectonic plates move the composition to the rocks.
