Question

2 how do convection currents in earths mantle affect the behavior of tectonic plates? a they create a stable environment that keeps the plates stationary b they cause the plates to move in a circular motion c they generate a force that pulls and pushes the plates more ↓ d they lock the plates

Explanation:

To solve this, we analyze each option:

• Option A: Tectonic plates are not stationary; convection currents drive movement, so A is wrong.
• Option B: Tectonic plates don't move in circular motion due to convection; they move in directions like divergent, convergent, or transform, so B is wrong.
• Option C: Convection currents in the mantle (hot material rises, cool sinks) create forces that push and pull tectonic plates, causing their movement (e.g., divergent boundaries from rising currents, convergent from sinking). This matches the scientific understanding.
• Option D: The description is cut off, but from context, it's incorrect as convection doesn't lock plates.

Answer:

C. They generate a force that pulls and pushes the plates
