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
What part of the earths interior is inferred to have convection currents that cause tectonic plated to move?
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.
What are some effects convection currents have on the world?
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.
In which part of earth core do convection currenys occurs?
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.
What is happening to create convection currents 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.
How are convection currents in the mantle and in the oceans similar How are they different?
The ocean currents are colder than the currents in the mantle,and the are located in different areas.

What do scientists think causes the movement of Earthes plates?
Convection movements; currents in Earth's interior. Note that a significant part of Earth's interior is liquid.
Are there convection currents in the molten part of the earths interior?
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.
How convection currents are related to plate tectonics?
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">
What part of Earths interior is inferred to have convection currents that cause tectonic plates to move?
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.
What part of the earths interior is inferred to have convection currents that cause tectonic plated to move?
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.
Which part of earth's interior is inferred to have convection currents that cause tectonic plates to move?
The mantle is inferred to have convection currents that cause tectonic plates to move. Heat from the Earth's core causes these currents, which transfer heat to the surface and drive the movement of the tectonic plates.
What are some effects convection currents have on the world?
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.
Where do you find convection currents?
Convection currents occur in the asthenosphere.
Why do convection currents happen in the mantle?
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.
What keeps the mantle from cooling down and becoming solid?
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.
