1. The document discusses different types of faults such as strike-slip, normal, and reverse faults. It also discusses concepts like focus, epicenter, magnitude, and intensity in relation to earthquakes. 2. Key information about earthquakes includes that they are caused by movements along faults and release energy rapidly. The focus is where fault slippage originates underground, while the epicenter is directly above on the surface. 3. Additional topics covered include tsunamis, which are large waves caused by undersea earthquakes, and how studying seismic waves can provide information about the interior of the Earth.

10. STRIKE-SLIP FAULT
A strike-slip fault forms when
the rock layers on opposite
sides of a fault slides past
each other horizontally. This
type of fault is sometimes
called as tear, wrench or
transcurrent fault.

12. NORMAL FAULT
A normal fault forms as a
result of tension. The rock
layers in the Earth’s crust are
pulled apart, and gravity
causes one section to move
downward in relation to the
other.

16. REVERSE FAULT
A reverse fault forms as a result
of compression. The rock
layers in the earth’s crust are
squeezed together, and the
force pushes one section
upward in relation to the other.
