Question

In what layer are convection currents found?

Answer 1

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.

Answer 2

Convention currents are found in the asthenosphere part present in the mantle of the Earth.

Explanation:

• The Mantle is the middle layer of the earth surface extending up to 2900 kilometers.
• Beneath the Mantle lies the core which contains molten rocks and materials called magma.
• The materials are highly radioactive and immensely heated. These highly hot condition creates pressure on the middle layer (Mantle).
• As a result, large convention currents are generated excessively.
