In the Earth's layers, rocks in the mantle are cooler than rocks in the core. Here's why:
1. The Earth has three main layers: the core, the mantle, and the crust. The core is the innermost layer, followed by the mantle, and then the crust.
2. The core of the Earth is extremely hot, with temperatures reaching up to several thousands of degrees Celsius. This heat comes from the radioactive decay of elements and the residual heat from the formation of the Earth.
3. In contrast, the mantle is cooler than the core but still quite hot compared to the crust. The mantle is made up of solid rock that can flow slowly over long periods of time due to its high temperature and pressure.
4. Rocks in the crust, which is the outermost layer of the Earth, can vary in temperature depending on their location and depth. However, on average, rocks in the mantle are cooler than rocks in the core.
So, in summary, rocks in the mantle are cooler than rocks in the core within the Earth's layers.
