What is the temperature range of the mantle?

The temperature range of the mantle is accurately represented as 1000°C to 3700°C. This layer of the Earth lies between the crust above and the outer core below and is primarily composed of silicate minerals. The temperature within the mantle increases with depth due to the geothermal gradient, where heat from the Earth's core and radioactive decay contributes to the overall temperature.

At the upper mantle, temperatures can start around 1000°C, while deeper parts can reach close to 3700°C, particularly near the boundary with the outer core. This range is critical for understanding mantle convection, which is a fundamental process driving plate tectonics. The provided range accurately reflects the thermal conditions experienced in this layer and is essential for comprehending geological phenomena such as volcanic activity and earthquakes.
