Same as with weather, but in stead of air, you've got molten rock: magma. Hotter magma is less dense than cooler magma (although they're both still quite hot enough to turn you to a crisp, of course), and thus rises towards the surface, where it releases heat into the crust. Having cooled down, it descends towards the core again, where it soaks up new heat, so that it starts to rise once more.

What is an example of convection in earths surface?
An example of convection in Earth's surface is the movement of tectonic plates. Heat from the Earth's interior causes the molten rock in the mantle to rise towards the surface, where it cools and sinks back down. This convection process drives the movement of the tectonic plates, leading to phenomena like earthquakes and volcanic activity.
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.
Does heat from the earths interior reaches earth through conduction?
Yes, heat from the Earth's interior is transferred to the surface primarily through conduction. The Earth's core is extremely hot, and this heat gradually moves towards the surface by transferring from one atom to another. Eventually, this heat reaches the crust and helps drive processes like plate tectonics and volcanic activity.
What drives convection within earths atmosphere?
Convection within Earth's atmosphere is primarily driven by the unequal heating of the Earth's surface by the sun. As air near the surface is heated, it becomes less dense and rises, creating an upward flow. As the heated air rises, it cools, becomes denser, and eventually sinks back towards the surface, completing the convection cycle that helps drive weather patterns.
What is the two layers below earths surface in which convection takes place?
The two layers below Earth's surface where convection takes place are the mantle and the outer core. In the mantle, convection currents are responsible for plate tectonics and the movement of Earth's lithosphere. In the outer core, convection currents drive the movement of molten iron that generates Earth's magnetic field.
How is heat from earths interior transferred to earths surface by convections?
Beneath the surface of the earth temperature remains the same. Within the Earth, irregular convection cells within the mantle transfer heat from the core to the surface of the planet. Volcanoes and earthquakes are two examples of heat transferring from the interior to the surface.
Convection currents produce the heat in the earths interior?
False.
What will happen to the convection currents in the mantle if the earths interior cools down?
the convection currents will stop
What causes air to move with the earths surface?
convection
What part of earths interior is inferred to have convection that cause tectonic plates to move?
the asthenosphere
What is directly linked to heat convection within earths interior?
Tectonic Plate Movement
What would happend to the convection currents in the mantle if earths interior eventually cooled down?
They will stop.
What is most directly linked to heat convection within Earths's interior?
tectonic plate motion
What is most directly linked to heat convection within Earths interior?
tectonic plate motion

Why earths interior is warmer than earths surface?
Earth's surface is free to radiate heat into space. The interior is not. The interior does transfer heat the the surface, but rather slowly. It is hot due to residual heat from Earth's formation and from the heat generated by the decay of radioactive elements.
What is an earthquake that may be far below the earths surface?
it is called the interior
