Question

what causes crustal plate movements?
a climate change
b violent volcanic eruptions
c convection currents in the earths mantle
d changes in earths weather

Explanation:

To determine the cause of crustal plate movements, we analyze each option:

• Option a: Climate change affects weather patterns and ecosystems, not plate movement.
• Option b: Volcanic eruptions are a result of plate movements (or related processes), not a cause of the movements themselves.
• Option c: Convection currents in the Earth’s mantle transfer heat, creating forces that drive the movement of tectonic plates. This is a key concept in plate tectonics.
• Option d: Changes in Earth’s weather are atmospheric phenomena and do not cause plate movements.

Answer:

c. Convection currents in the Earth’s mantle
