Explanation:

Convection is a type of heat transfer of thermal energy when a fluid, like air or a liquid, is heated . Heat energy is transferred from hot places to cooler places. not only that but the initial heat transfer between the object and the fluid takes place through conduction

within these regions are all the major types of biomes in the world. a biome is a community of animals and plants spreading over an extensive area with a relatively uniform climate. some diverse biomes represented in north america include desert, grassland, tundra, and coral reefs.
