1. SMOM y 6: Picture Analysis s. Read and analyze figures A and B. Answer the questions stated below. Figure A shows the process of confection in the earth's mantle. How does it affect the formation of mountains and the temperat:ire in the surface (ground)?
Answer:
Convection currents carry heat from the lower mantle and core to the lithosphere. ... As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense. The less-dense material rises, often forming a mountain or elevated area of the seafloor.
