Eduardo Pineda · Answer 1

The given blanks can be filled with gradual creeping movement and Earth's.

Mantle convection refers to the gradual creeping movement of the solid silicate mantle of the Earth resulting due to convection currents conducting heat from the interior to the surface of the planet. The convection currents in the magma mediate plate tectonics.

The heat produced from the radioactive decay of the elements deep in the inside of the Earth produces molten rock in the asthenosphere. As a consequence, the Earth's plates move gradually.

Russell Schwartz · Answer 2

Solution:

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.

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