Tide retreats as a warning, tsunami waves hit, water recedes back into the ocean carrying all the debris
I have NO idea
True or False? When you are out in the ocean, you might not even be able to detect a tsunami wave.
True
False
Wait, what?
This type of fault is....
normal fault

True
False
When the crust is stretched by rock moving in opposite directions, compression occurs.
True
False
How does folding affect Earth's surface?
Folding causes the crust to buckle, and over time, to rise up and form mountains.
Folding causes the crust to sink.
Folding causes the crust to bend in half.
Folding has no effect on Earth's surface.
