What certain part of the mantle is cooler than the part surrounding it what my happened to the cooler rock?
The lower mantle is generally cooler than the surrounding upper mantle due to its greater depth and pressure. This cooler rock can become denser, which may lead to slower convection currents. Over geological time, it can also be subjected to processes like subduction, where it may descend into the mantle and eventually recycle into the mantle's interior.
Is earths mantle hotter or cooler than the crust?
The mantle is hotter than the crust.
Is the earths core cooler than the crust and mantle?
No, the core is hotter.
Would you expect the mantle to be hotter or cooler than the inner and outer cores?
The mantle is expected to be cooler than the inner core but hotter than the outer core. The inner core is the hottest layer of the Earth, while the outer core is composed of molten iron and nickel. The mantle, located between the crust and core, experiences convection currents due to heat from the core, making it warmer than the outer core but cooler than the inner core.
What is believed to cause lithosperic plates to move?
The movement of lithospheric plates is primarily driven by the process of plate tectonics, which is caused by convection currents in the Earth's mantle. As the hot material rises and cooler material sinks in the mantle, it creates forces that push and pull the plates, causing them to move over the surface of the Earth. This movement can result in phenomena like earthquakes, volcanic eruptions, and the formation of mountain ranges.

Is earths mantle hotter or cooler than the crust?
The mantle is hotter than the crust.
Which boundary separates the earth's crust and the cooler part of the mantle?
The boundary that separates the Earth's crust and the cooler part of the mantle is called the Mohorovičić discontinuity or Moho. It marks the transition between the Earth's crust and the uppermost part of the mantle.
Is the rock in the crust able to move around more easily than the rock in the lower mantle since the rock in the crust moves around differently than rock in the lower mantle?
The rock in the lower mantle moves around easily than the crust. This is because rock in the lower mantle is hotter and closer to its melting point. Rocks in the crust are cooler thus harder to move around.
How does the mantle get energy to move in convection currents?
The mantle gets energy to move in convection currents from the heat generated by the radioactive decay of elements within the Earth's interior. This heat causes the mantle material to become less dense, leading to its upward movement. The cooler, denser material then sinks back down, completing the convection cycle.
Is the earths core cooler than the crust and mantle?
No, the core is hotter.

Is rock in the crust able to move around more easily than the rock in the lower mantle?
No it's the other way round. Rock in the mantle is hotter, nearer to its melting point (though it's still solid) and so can move around quite easily. Rock in the crust is much cooler, like frozen ice and so it is much harder to move around.
