1 Earthquake By: Kyle  Shane  Jordana

2 What is an Earthquake? Earthquakes are sudden shaking of the earth caused by massive rocks, called plates, moving under the earth's surface. As the plates bump and grind into each other, the pressure builds as they attempt to pass each other. The pressure builds and the plates shoot past each other breaking off to pieces. Above the Earth's surface, the land shakes and buildings crumble.

3 Causes of Earthquakes The edge of one plate is pushed under another.
Plates can also push together and that can cause the rock to bend and fold.  It happens when the plates push together.  It also happens when plates push over another.  Earthquakes happen near cracks in the earth called faults. 

4 Earthquake Effects What happens after an earthquake hits:
The power could go out. After shock can happen. It is a mini earthquake after a big earthquake. Land can collapse and roads can break. Homes can fall apart. Pipes can break and gas can come out of the pipes. 

5 earthquake: Survival Kit
List supplies that will be helpful   important and  have in an earthquake. Lots of water. Lots of food. batteries Flash light. Five or six sleeping bags. Medicine.

6 Interesting facts about Earthquakes
There are 20 plates on earth. Plates are called tectonic plates. Sometimes a tectonic plate pushes over a another and that is called a thrust fault. When tectonic plates separate the middle of it is called the Rift Zone.  

7 Earthquake Vocabulary
Tectonic plates The theory of plate tectonics is an interesting story of continents drifting from place to place breaking  apart, colliding, and grinding against each other. Fault plate When plates slip, it's called a fault plate23 Aftershock An aftershock is a small earthquake that occurs after a large one. Fault A fault is a crack in the Earth's crust.
