The temperature of the Earth’s mantle varies widely depending on depth. Generally, it ranges from about 500 degrees Celsius (932 degrees Fahrenheit) near the upper boundary of the mantle to about 4,000 degrees Celsius (7,232 degrees Fahrenheit) at the core-mantle boundary.
To explain further, the Earth’s mantle is a thick layer of rock located between the Earth’s crust and the outer core. As you go deeper into the Earth, the temperature increases due to the intense pressure and heat generated from the radioactive decay of elements within the Earth. This heat causes the rocks in the mantle to become more pliable and contributes to the movement of tectonic plates.
Understanding the temperature of the mantle is critical for geologists as it provides insights into geological processes like volcanic activity and plate tectonics.
