Question

question 3 of 10
what is the term for the circular movement of material inside earths mantle?

a. conservation

b. convection

c. equilibrium

d. density

Explanation:

To solve this, we analyze each option:

• Option A: Conservation refers to the principle of something being preserved (e.g., energy conservation), not related to mantle material movement.
• Option B: Convection is the circular movement of a fluid (or semi - fluid, like mantle material) due to temperature differences, causing warmer, less dense material to rise and cooler, denser material to sink. This matches the circular movement in Earth's mantle.
• Option C: Equilibrium is a state of balance, not a movement process.
• Option D: Density is a measure of mass per unit volume, not a movement.

Answer:

B. convection
