Earth’s continents are constantly in motion because they sit on top of gigantic plates which float on earth’s mantle. energy from the earth’s core creates convection currents in the molten layer, and the currents move the plates. over extremely long periods of time, this movement creates new a. biomes b. plates c. atmospheric layers d. elements

Biomes.

Explanation: The movement of plates generates convection currents and these currents in the longer term creates a new environment.

This change in environment creates different kind of biomes. Each of the biome is known by its particular temperature and rate of precipitation.

There are many biomes present on earth having different temperature and rate of precipitation. Example: Desert biome has high temperature with low rate of precipitation.
