What is a seismic wave

• A seismic wave is when pressure from the earth causes rocks along faults to move and break.There are 3 types of seismic waves

What is an earthquake

• A earthquake is a movement or vibration of the earth. They are caused by the release of stored energy in earths outer layer.This release of energy causes sudden shifts of rocks along faults

Tectonic Plates

The earth is like a big cracked egg. On earth

there are 7-8 major tectonic plates and many

mirror plates.

All about faultsWhen rocks found along a

break move, the break is called a fault.Around the tectonic plates there are

faults. Earthquakes happen around faults.

Primary Waves• Also known as P

waves.

• The primary wave is also the fastest waves.

• It is first to arrive at a distant point.

• It can travel through solids,liquids,and gases.

Secondary Waves• Also known as S

waves

• They are slower than P waves

• And they arrive later at the distant point.

• Travels through solid only

Surface Waves

• Also known as L waves

• They are the slowest but they cause the most damage

• They are felt at the surface

Seismographs

• A seismograph is a tool that helps scientist record the force and duration of an earthquake.It records the information on a seismogram.

What is earths

structureThere are 4 parts to the earth.The 4 parts of the

earth are:crust,mantle,outer core,and Inner core.

Crust

• The crust is earths outer layer

• It is also the thinest layer and we live on it.

• It is deeper under continents then oceans

Mantle

• The mantle is the thickest layer.

• It is a layer of rock lying below the crust.

• Also it is allows tectonic plates to move slowly.

• Rocks move or flow due to high temperatures.

The Core• The core is split into two

parts inner and outer

• The outer core is made of melted iron.It is totally liquid and the inner core floats in it.

• The inner core is a solid sphere.It is the center of the earth. It spins a different rate than the rest of the planet.
