Michael and Jose are studying about plate tectonics. They learned that plates usually move a few centimeters every year. They learned that the movement of heated material caused the plates to move. In which layer does the heated material move?

Mantle layer

Explanation:

The movement of heated materials on the mantle layer of the earth helps in the movement of the tectonic plates. The earth is made up of four layers and they are the crust, the mantle, the outer core, and the inner core. The tectonic plates are always in motion which is very slow but constant.

The convection currents emanating from the mantle layer of the earth aids the movement of the tectonic plates. Natural disasters like earthquakes can result from the intense pressure emanating from the movement of the plates.

the answer is true when observing or determining population size, a direct observation is use, in which each organism is counted in a population or in an area. one benefit of this measure is that you get the exact population count but it will take a long time to  determine  the  size  of a  population.
