The soft part of the mantle where convection currents occur is known as the asthenosphere. This region lies beneath the lithosphere and is characterized by partially molten rock that allows for the flow of material. The convection currents in the asthenosphere are driven by heat from the Earth's core, facilitating the movement of tectonic plates above. These currents play a crucial role in geological processes such as plate tectonics and volcanic activity.
Convection currents in the mantle
It is the mantle that is inferred to have convection currents that cause tectonic plates to move. Heat from the Earth's core creates these currents, which drive the movement of the rigid plates on the Earth's surface.
Convection currents inside the Earth happens. The part where the convection currents go up, it brings up materials from the mantle like rocks. This forms new crust. When the convection currents go down, it brings down some older, colder oceanic crust to the mantle, destroying it. In conclusion, the crust is formed and destroyed when convection currents inside the Earth happen.
Convection currents primarily occur in the Earth's mantle, which lies between the outer core and the crust. These currents are driven by the heat from the Earth's core, causing the mantle's semi-solid rock to slowly flow and circulate. This movement plays a crucial role in plate tectonics and the geological activity on the Earth's surface. While the outer core is liquid and also convecting, the convection currents that significantly influence surface processes are predominantly found in the mantle.
in the asthenosphere, which is in the lower part of the mantle, magma churns in a convection current which is like a cycle. Tectonic plates sit above this movement in the lithosphere. This is what causes continents to move little by little. Hot magma rises and at the lithosphere, it cools and falls because it is now denser. This is like a circular movement, or convection current.
The ocean currents are colder than the currents in the mantle,and the are located in different areas.
Convection currents in the mantle
Convection movements; currents in Earth's interior. Note that a significant part of Earth's interior is liquid.
Yes, there are convection currents in the molten part of Earth's interior, known as the mantle. Heat from the core drives these currents, causing hot molten rock to rise, cool, and then sink back down in a continuous cycle. These convection currents play a key role in plate tectonics and the movement of Earth's crust.
Because convection currents is the heating rising cooling process and if the crust and part of the upper mantle wasn't divided into sections the heated material couldn't rise up. ="overflow:hidden;background-color:transparent;text-align:left;text-decoration:none;border:mediumnone">
The mantle is inferred to have convection currents that cause tectonic plates to move. Heat from within the Earth creates these currents, leading to the movement of the rigid plates on the Earth's surface.

Convection currents occur in the asthenosphere.
The convection currents are a result of heat from the interior of the Earth. The rock of the upper mantle known as the asthenosphere is plastic-like but not molten. It acts like a conveyor belt, moving heat from Earth's interior upward, and cooled material downward in a big loop. New crust is created where mantle material reaches the surface at places called mid-ocean ridges. Older, colder oceanic crust is subducted and drawn into the mantle, completing the loop.
The mantle is kept from cooling down and solidifying due to the heat generated from the decay of radioactive elements in the Earth's core. This heat creates convection currents within the mantle, which continuously bring warmer material from deeper layers up towards the surface, helping to maintain the mantle's high temperature and molten state.
