Question

How is this circular motion achieved? Heat ‘"pushes" the magma up, and when it hits the lithosphere it is pushed back down towards the core. Heated magma is magnetic and is drawn to the lithosphere where it loses its magnetic force and drops back down due to gravity. Heated magma rises from the core, but rocks in the asthenosphere block the magma on each side, causing it to move in small circles. Hot magma rises and pushes up toward the lithosphere, and as it cools it cycles back down toward the core to be heated again.

Answer 1

Hot magma pushes up toward the lithosphere and as it cools cycles back down again taward the core to be heated again.

Answer 2

Answer;

Hot magma rises and pushes up toward the lithosphere, and as it cools it cycles back down toward the core to be heated again.

Explanation;

• Inside the earth's mantle, magma is heated by the heat resulting from the friction of the core active particles and the heat from when the earth was formed.
• The heated magma rises, in a similar way like boiling water. When the magma reaches to the top, it cools from the crust and sinks back down to the core.
• Like boiling water, magma creates movement of a circular motion known as convection currents. These convection currents are responsible for the movement of the plate tectonics across the earth.
