Question

study the image of earths interior
which phrase explains what the arrows show?
how convection currents move in earths interior
the location of heated material near earths surface
where plates move as material cools in the outer core
why the densities of materials remain constant at different layers

Explanation:

To solve this, we analyze each option:

• Option 1: Convection currents in Earth’s mantle (the layer shown) involve heated material rising, cooling, and sinking, matching the arrow directions (upward for rising, curved/downward for sinking/circulating).
• Option 2: Heated material near the surface is not the focus; convection occurs in the mantle, not just near the surface.
• Option 3: Plates move due to mantle convection, not cooling in the outer core (outer core is liquid, but convection here isn’t plate - driving).
• Option 4: Density changes with depth (due to pressure, composition), so densities aren’t constant.

Answer:

how convection currents move in Earth’s interior
