Which explanation best describes convection currents in the Earth's mantle?(1 point)

Responses

Cooler mantle rock close to Earth's outer core rises while warmer mantle rock closer to Earth's crust sinks.
Cooler mantle rock close to Earth's outer core rises while warmer mantle rock closer to Earth's crust sinks.

Heated mantle rock close to Earth's outer core rises while cooler mantle rock closer to Earth's crust sinks.
Heated mantle rock close to Earth's outer core rises while cooler mantle rock closer to Earth's crust sinks.

The dense and hot inner core sends seismic waves into the mantle which results in a circular motion of rock.

Convection currents do not occur in Earth's mantle, but in Earth's inner core.

The explanation that best describes convection currents in the Earth's mantle is:

Heated mantle rock close to Earth's outer core rises while cooler mantle rock closer to Earth's crust sinks.

This description accurately reflects the process of convection, where hot material rises and cooler material sinks, creating a circulation pattern within the mantle.
