PLEASE PLEASE PLEASE! HELP ME NO! 1. Mountains on the bottom of the Atlantic Ocean were made from:
A. A meteor crashing into the ocean
B. Erosion and weathering
C. Sedimentation and deposition
D. Seafloor spreading and cooling magma

2. When two plates collide what may happen?
A. Earthquakes
B. Mountain formation
C. Volcanic activity
D. All answers are correct.

Question 1 = D / Question 2 = D

Explanation:

1) A mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.

2) If two tectonic plates collide, they form a convergent plate boundary. Usually, one of the converging plates will move beneath the other, a process known as subduction. Deep trenches are features often formed where tectonic plates are being subducted and earthquakes are common.
