Question

What is the temperature variation in the mantle in °C?

Options

• 1500 to 3700

• 1500 to 2500

• 1000 to 3700

• 1000 to 4000

Answer 1

1500 to 3700

Explanation:

The temperature in the mantle ranges from around 1500°C near the top (in the upper mantle) to approximately 3700°C near the boundary with the core. The temperature increases with depth due to the heat generated by the decay of radioactive elements and the heat from the Earth's core.
