Magma
This layer is 5 to 25 miles thick and scientists know the most about this layer
The crust
This natural disaster occurs when tectonic plates rub, collide, or pull apart under the oceans crust causing large waves
Tsunami
This rock types is where most fossils can be found
Sedimentary
These volcanoes form overnight and dry out quickly
Ciner cone
This is the hottest layer and is made of solid iron
Inner core
This scale is used to measure the strength of an Earthquake
Richter Scale
All rocks begin as this type of rock
Igneous
These volcanoes contain thin runny lava and least dangerous
Shield Volcanoes
This is the thickest layer and is made of molten rock
The Mantle
The point where an earthquake is at its strongest
Epicenter
Rocks that change form, from either igneous or sedimentary due to chemical reactions
metamorphic rocks
These volcanoes contain hot sticky magma and are the most dangerous
Composite Volcanoes
These semi solid plates are located beneath the crust and are responsible for earthquakes
Tectonic Plates
