Question
Give two reasons that support the belief that the interior of the earth is very hot.
Answer
- Layers of the overlying rocks exerts pressure hence the interior is hot
- After formation of the earth the interior cooled slowly compared to the exterior, thus the interior still retains much of its original temperature
- Radioactivity
- mineral elements with the interior react with each other thus exploding to produce heat
