What is the role of radioactive decay in Earth's interior?
Understand the Problem
The question is asking about the specific role of radioactive decay within the Earth's interior, particularly regarding its effects on heat generation and geological processes. It is focused on understanding how this natural phenomenon impacts the planet's structure and behavior.
Answer
It generates heat that drives convection currents.
The role of radioactive decay in Earth's interior is to generate heat that drives convection currents.
Answer for screen readers
The role of radioactive decay in Earth's interior is to generate heat that drives convection currents.
More Information
Radioactive decay of isotopes like uranium, thorium, and potassium generates heat, contributing significantly to Earth's internal temperature. This heat supports tectonic activity and the rock cycle.
Tips
A common mistake is confusing the generation of heat with cooling processes. It's important to remember that radioactive decay primarily generates heat.
