Question

how are the crust and the inner core alike? a they are both solid. b they both have the same temperature. c they are both under the same pressure. d they are both very close to the center of the earth.

Explanation:

To determine how the crust and inner core are alike, we analyze each option:

• Option A: The Earth's crust (outermost layer) and inner core (innermost layer) are both solid. The crust is solid rock, and the inner core is solid due to extreme pressure (even though it's very hot).
• Option B: The inner core is extremely hot (much hotter than the crust), so they don't have the same temperature.
• Option C: The inner core is under immense pressure (far more than the crust), so pressure differs.
• Option D: The crust is the outermost layer, far from the center, while the inner core is at the center. So this is incorrect.

Answer:

A. They are both solid.
