How does convection under Earth's surface happen?
Convection under the Earth's surface occurs due to the heat generated by the radioactive decay of elements in the Earth's interior. This heat causes hotter materials to rise and cooler materials to sink, creating a circular motion of material within the Earth's mantle. This convection helps drive the movement of tectonic plates and contributes to processes like seafloor spreading and subduction.
What drives volcanic activity on Earth's surface?
Convection
What does the mantle convection cause?
Mantle convection is the slow motion of the Earth's silicate mantle, caused by convection currents that carry heat from the interior to the surface of the Earth. Mantle convection causes the tectonic plates to move around the Earth's surface, causing earthquakes, tsunamis, and volcanic activity.
What do you think will happen to the convection current in the mantle if the interior of earth eventually cools down?
If the interior of the Earth cools down, the convection currents in the mantle will gradually slow down and eventually stop. This will result in decreased heat transfer and mantle movement, potentially leading to a decrease in tectonic plate movement and volcanic activity over time.
How are convection currents set up in air?
Convection currents in air are set up by the unequal heating of the Earth's surface. When a portion of the Earth's surface is heated more than another, the warm air rises, creating a low-pressure area. Cooler air then moves in to fill the void, creating a convection current.
What will happen to the convection current in the mantle if Earth's interior eventually cools down?
the convection currents will stop
What happen as thermal energy is transferred from the core to the mantle?
As thermal energy is transferred from the core to the mantle, it causes convection currents in the mantle. These currents are responsible for the movement of tectonic plates at the Earth's surface. This movement leads to processes such as seafloor spreading, subduction, and volcanic activity.
What is the convection current hypothesis?
The convection current hypothesis supposes that convection currents in the Earth's Mantel (the zone below the surface/crust and above the Earth's core) cause the movement of the tectonic plates (plates that make up the surface/crust of the Earth and shift/move on a grand time scale).

This convection helps drive the movement of tectonic plates and contributes to processes like seafloor spreading and subduction.
Convection currents carry thermal energy from the sun to Earth?
No. Convection requires a medium to carry thermal energy from one place to another. There is no or not enough of any material in space to accomplish this. Radiation will carry thermal energy from the sun to the Earth.

How is heat transferred from the interior to the surface of Earth?
Heat is transferred from the interior to the surface of the Earth through a process called convection. In the Earth's mantle, hot material rises towards the surface, carrying heat with it. This movement creates convection currents that transfer heat from the interior to the surface.
What type of current drives earth's plates?
They are convection currents in the earth's mantle.
