How Earthquakes Work
Do you know how earthquakes form? Well, imagine how it
feels when you are standing on a moving surface. It’s shaky and
scary. Earthquakes happen when the ground shakes and moves.
Showing a earthquake and how it is cracked up.
What is a Tectonic Plate?
A tectonic plate is broken pieces of earth’s crust that fit like a
puzzle.These puzzle pieces move every year. They move about
0-6 inches per-year.Tectonic plates move on hot magma. The
tectonic plates are in outer surface of earth’s crust called
lithosphere.

Where Most Damage Occurs
Most damages occur where most people are and where they
live. They also occur where most buildings are and where homes
are. Earthquakes cause lots of damage. people get scared when it
comes.
Showing what damage from an earthquake.
What Damage There Is
People homes run down, glass breaking, cars smashing. People
also losing lives. Trees will be falling down.It feels shaky, and
when an earthquake comes, the ground will come apart. Surface
waves cause ground movement, and the ground will break apart.
People can get stuck in house open cracks.

Chapter 3: Causes of Earthquakes
Forces build up slowly and eventually become so strong that
they cause rocks to break underground.That’s how it makes the
ground to break underground. These forces are called seismic
waves.
Showing how ground breaks underground
What Are Tectonic Plates?
Tectonic plates are segments of lithosphere. Lithosphere is the
outer part of the earth,consisting of the crust and upper mantle.
They are also broken pieces of earth’s crust.

Rough Roads
There will be cracks open on roads. These cracks are called
faults. People can get stuck in crack open roads. They can be so
dangerous.
Cracks on roads
Measuring Earthquakes
Scientists use a tool called Seismograph to measure an
earthquake. They are measured on a Richter Scale. That’s how
we know how big an earthquake is.
