What is the primary cause of convection currents within Earth's mantle?
Understand the Problem
The question is asking about the primary factor that causes convection currents in Earth's mantle. It seeks to identify the most significant reason among the provided options that relates to the dynamics of the mantle's behavior.
Answer
The temperature difference between the core and crust.
The primary cause of convection currents within Earth's mantle is the temperature difference between the core and crust.
Answer for screen readers
The primary cause of convection currents within Earth's mantle is the temperature difference between the core and crust.
More Information
Convection currents are driven by the heat from the Earth's core, causing hot, less dense material to rise and cooler, denser material to sink.
Tips
Avoid confusing factors like the rotation of Earth or gravitational pulls, which aren't the main causes of mantle convection.
