Question

Mantle convection is a process of______ that creates circular currents in the asthenosphere. As a result, the ______ plates slowly move.

Answer 1

Mantle convection is the slow creeping motion of Earth's solid silicate mantle caused by convection currents carrying heat from the interior to the planet's surface. Convection currents in the magma drive plate tectonics. Heat generated from the radioactive decay of elements deep in the interior of the Earth creates magma (molten rock) in the aesthenosphere. The aesthenosphere (70 ~ 250 km) is part of the mantle, the middle sphere of the Earth that extends to 2900 km.

As a result, the plates of the Earth’s move slowly move.

Answer 2

Mantle convection is a process of fluids that creates circular currents in the asthenosphere. As a result, the tectonic plates slowly move.

Step-by-step explanation:

The mantle convection refers to the movements of internal fluids that take place in the mantle, below the earth's crust creating circular currents in the atmosphere. They are believed to be largely responsible for numerous processes of transformation of relief of endogenous origin, such as earthquakes, volcanisms, plate tectonics, among others. The tectonic plates, specifically move because of the mantle convections.

The convection cells and their movements occur because the magma does not have a homogeneous temperature. The region closest to the nucleus is the warmest and the region closest to the crust is "coldest". Thus, the magma that is higher and that has lower temperatures “goes down” towards the nucleus and the more heated magma, being lighter, goes up towards the crust.
