Question

What layer of the Earth is starting these convection currents driving the plate movement? (2pts)

Answer 1

The layer of the Earth that is responsible for driving the convection currents and plate movement is the asthenosphere.

Answer 2

Write a brief summary of the lab 2-4 sentences. Include how the videos demonstrate convection current and how this relates to plate tectonics that we have learned about in this Unit and in Unit 5. (2pts)

Answer 3

In the lab, videos were used to demonstrate convection currents, which are key drivers of plate tectonics. These videos showed how heat from the Earth's core causes material in the asthenosphere to rise and eventually cool near the surface, then sink back down. This process creates a circular flow of material, known as convection currents, which exert force on the lithospheric plates above. The movement of these plates results in processes such as seafloor spreading, subduction, and the formation of mountains, aligning with our understanding of plate tectonics as a whole.
