A break in the earth's crust
fault/boundary
This state is mostly made of Volcanoes.
Hawaii
The Earths Crust is made of these which are constantly moving....hold on!
Plate Techtonics
Sea floor spreading is found at which type of plate boundary?
Divergent
When plate spread apart?
Divergent
The type of boundary occurs when two plate techtonics slide past eachother.
Transform Boundary
This is an area not on a plate boundary where volcanoes frequently occur
hot spot
This layer of the earth is the hottest.
Inner Core
They can form when earth's plates collide
Mountains
What special feature does a convergent plate boundary form?
Trench
This type of boundary occurs when plate techtonics is pushed up past another plate techtonic.
Convergent Boundary
Before it comes out of the earth, what is lava referred as?
Magma
The earth's outer core is made up of this
very dense liquid
The theory that continents drifted apart is called?
Continental drift
Your nails
This device measures ground movement, measure earthquakes
seismograph/richter scale
What is the first stage of the rock cycle?
A volcano erupting creating igneous rock
Most of the earth's mass is located here (thickest layer)
mantle
The force that moves tectonic plates
convection currents in the mantle
What layer causes the plates to move
Mantle or asthenosphere
This is the point that sits on the Earth’s Crust directly above the Earthquakes focus.
Epicenter
This country is getting bigger as we speak!
Iceland
What makes up and what is located in the Lithosphere?
Earth's crust/tectonic plates
What is one piece of evidence that supports Wegener's theory of continental drift
Continents shape, Fossil records and alternating rows of magnetism on the ocean floor near the Mid Atlantic ridge
How many major plate are around earth
