When tectonic plates slide past each other ..
An earthquake occurs
A tsunami occurs
Nothing happens

2
Which of these happen where tectonic plates move apart?
Crust is pushed upward by collisions and large mountains or ridges form.
Crust is pushed down underneath plates, where it is recycled.
Magma comes to the surface and cools, creating new crust.
