Lab Question 1: Convection in the mantle is caused by (1 point) the outer core heating the rock near it, causing the liquid rock to rise up towards the cru the outer core heating the rock near it, causing the liquid rock to sink towards the core.

Convection in the mantle is essentially a giant slow-motion conveyor belt! The heat from the outer core warms the rocks in the mantle, causing them to become less dense and rise towards the crust. As they cool near the surface, they sink back down to be heated again, creating a continuous cycle. It’s like a lava lamp but on a planetary scale! This convection process is crucial for the movement of tectonic plates. As the mantle flows, it drags the plates along with it, contributing to phenomena such as earthquakes, volcanic eruptions, and the formation of mountain ranges. So, the next time you feel the earth tremble, just think of that bustling mantle convection happening beneath your feet!
