9. Which process, once it begins, causes Earth's temperature to drop considerably and decreases sea levels?

A. Plate tectonics

B. Climate change

C. Oxygen production

D. Glaciation

Glaciation not only causes Earth to become stone cold, when glaciation occurs the water from precipitation becomes trapped in the glaciers instead of going back into the ocean. Without any new source of water sea levels decrease a lot.

for e2020. the answer would be some directions from the mountain range so we can find mt. whitney. to locate which direction is north, you should use a   compass. this would not only find mt. whitney, but also becuase of this long paragraph you would get points because it's not like anyone actually reads your work becuase once they read the first sentence it sounds dumb enough to not read becuase i'm not good at answering this but the answer is compass for your benefit.
