Answer 2

It's against the rules for us to just answer all of your questions, is there a specific question you need help with?

Answer 3

2. I think 200 years
3. Antartic
4. rise
5. submarine canyons

Answer 6

is this a test?

Answer 7

No @pooja195 study quide but I need my study guide to be correct to do well on the rest of this unit

Answer 9

I take my classes online and my teachers post these and if you want you can use them but we dont have to I just think they help alot.

Answer 10

@mstv1112 #7 is They are geologically very stable, Scientist named Griggs developed a unique gravimeter that could measure gravity in the stable environment of a submarine and used it to measure gravity over trenches. His measurements revealed that trenches are sites of downwelling in the solid Earth.

Everything else looks to be right.

Answer 11

So #7 is B

And you're pretty sure about my answers?

Answer 12

#7 would be C, because griggs experiment proved that they were not stable when he tried to measure gravity.

Answer 13

Ooh okay. Thank you very much. I appreciate your help/
