Question
The diagram below shows the Earth's mantle undergoing a process known as convection.Image courtesy of USGSWhich statement about convection in the Earth's mantle is true? A. Convection continuously cycles matter between the Earth's core and its crust. B. Convection causes the Earth's crust to be warmer than it otherwise would be. C. Convection contributes to the movement of the Earth's tectonic plates. D. all of these
Solution
The correct answer is C. Convection contributes to the movement of the Earth's tectonic plates. This is because the heat from the core of the Earth causes the mantle's material to rise. When it reaches the top, it cools and then sinks back down, creating a cycle. This movement can cause the tectonic plates on the crust to move, leading to phenomena like earthquakes and volcanic activity.
