Convection Currents in the Mantle

Front

What are convection currents?

Back

Convection currents are the movement of fluid (like molten rock) caused by differences in temperature and density, leading to the transfer of heat.

Front

What is the main heat source for convection in the Earth's mantle?

Back

The main heat source for convection in the mantle is the Earth's core.

Front

What role does the crust play in convection currents?

Back

The crust is the outer layer of the Earth that is affected by the movement of convection currents in the mantle.

Front

How do convection currents affect tectonic plates?

Back

Convection currents in the mantle cause tectonic plates to move, leading to geological activity such as earthquakes and volcanic eruptions.

Front

What is the cooling source for convection in the mantle?

Back

The cooling source for convection in the mantle is the Earth's crust.

Front

Where do convection currents occur in the Earth?

Back

Convection currents occur in the mantle, which is located between the crust and the core.

Front

What happens to the material in the mantle when it heats up?

Back

When material in the mantle heats up, it becomes less dense and rises towards the crust.

Front

What happens to the material in the mantle when it cools down?

Back

When material in the mantle cools down, it becomes denser and sinks back towards the core.

Front

What is the relationship between convection currents and plate tectonics?

Back

Convection currents drive the movement of tectonic plates, influencing their interactions and the formation of geological features.

Front

What is the cycle of convection currents?

Back

The cycle of convection currents involves the rising of hot material, cooling at the surface, and sinking of cooler material back down.
