What is shearing and how does it work?
Plates slide past each other at transform boundaries, and the pieces of rock rub together; like the blades of a pair of scissors and causes the rock to break.
What does tension do to Earth’s crust?
Tension makes the crust longer and thinner.
How does a reverse fault differ from a strike-slip fault?
Wow, you really know your stuff! / Sorry, we were looking for...
Why are faults often produced along plate boundaries?
Plates collide with, grind against, and slide alongside each other, causing faults.
Why do some mountains form as folded mountains and others form as fault-block mountains?
Whether or not the rocks break as their plates rub against and into each other.
How does a plateau form?
When rock layers are pushed upward.
How do most earthquakes occur?
Energy can build up in the rock along plate boundaries for years or even decades. When the rock breaks or slips, energy is released, and Earth’s crust moves.
What is the focus of an earthquake?
The point below the surface of Earth where an earthquake begins.
Why do most earthquakes occur near or along a fault?
Wow, you really know your stuff! / Sorry, we were looking for...
Do all earthquakes occur at plate boundaries? How do you know?
No, because the effects of strong earthquakes have been felt well beyond the plate boundary at which they occurred.
