Inside The Earth By Quinn Williams

Interdiction • Earthquake are caused by the earths seismic waves. A seismic wave is an vibration or movement in the earth that makes the earths move.

Primary Waves • A primary wave is called a p wave. • Primary waves are the first movement or vibration of an earthquake. • A primary wave is the fastest wave • Primary waves can go through solids, gases, and liquids.

Secondary Wave • Secondary waves are called S waves. • The secondary waves are the second movement or vibration in a earthquake. • A secondary wave is slower than a p waves. • It only travels through solids

Surface Waves • A surface wave is called a l wave or a long wave • A surface wave is the slowest wave of all. • A surface wave causes the most damage. • A surface wave is felt at the surface.

Seismograph • A seismograph is an instrument that scientist track when an earthquake is coming.

Crust • Earths crust is a thin rock. • We live on Earths crust • Earths crust is the most outer layer. • Earths crust is the thinnest layer.

Mantle • The mantle is the thickest layer. • The mantle is below the crust • It allows the titanic plates to move around. • It is the third hottest layer.

Outer core • The outer core is made of melted iron • The outer core is below the crust and the mantle. • The outer core is totally liquid. • The inner core floats in the outer core

Inner core • The Inner core is a solid sphere. • The Inner core is in the center of the earth! • It is very hot
