The material in Earth's mantle is driven by convection currents. The heat of the Earth's core is carried toward the surface as hot magma expands and rises. When the current reaches the solid lithosphere, it spreads and moves in different directions along the bottoms of tectonic plates. The diagram below illustrates this process. The red circle indicates a location where a convection current reaches the lithosphere and spreads in different directions as it cools.

Question

The material in Earth's mantle is driven by convection currents. The heat of the Earth's core is carried toward the surface as hot magma expands and rises. When the current reaches the solid lithosphere, it spreads and moves in different directions along the bottoms of tectonic plates. The diagram below illustrates this process. The red circle indicates a location where a convection current reaches the lithosphere and spreads in different directions as it cools.

The following diagram is of the Earth's surface from above. The yellow lines indicate the boundaries between the Earth's major tectonic plates. The arrows indicate the directions and relative speeds of the plates as they move.

Which red circle on the diagram indicates a location at which a convection current of hot, liquid magma is reaching the lithosphere and spreading?

To identify the red circle on the diagram that indicates a location where a convection current of hot, liquid magma is reaching the lithosphere and spreading, look for a circle that is located near the boundaries of the tectonic plates and is associated with seafloor spreading or subduction zones. Typically, these areas are characterized by volcanic activity or geological features such as mid-ocean ridges.

If there are circles marked on the diagram, select the one that is closest to these tectonic boundaries or shows signs of volcanic activity. Without the visual of the diagram, I can’t specify precisely but generally, look for clues of where hot magma would influence or cause movement along the tectonic plate boundaries.
