Untitled Slide

Earthquakes, also called temblors, can be so tremendously destructive, it’s hard to imagine they occur by the thousands every day around the world, usually in the form of small tremors.

Most earthquakes occur at fault zones, where tectonic plates—giant rock slabs that make up the Earth's upper layer—collide or slide against each other.

THE 3 DIFFERENT PLATES

• Divergent- pulls apart
• Convergent- push it to gether
• Transform- slide past each other

Untitled Slide

• Convergent is the most deadly

HOW TO MEASURE

• It's on a scale from 1-10
• 1 is the lest
• 10 is the greatest

Untitled Slide

• Magnitude 8 hit the earth every year
• Some 10,000 people die be earthquake
• Every year

Untitled Slide

• Earthquake can strike more then once
• They can hit any time
• Most times it hits by the epicenter

VOCAB

• Fault. A break or separation in rock,Usually between two or more tectonic plates.
• Focus. The source of the earthquake inside the earth,where the rock first break.
• Seismic waves. Vibrations that's move through the earth in a way similar to waves moving
