Plate tectonics

What is plate tectonics?

• The Earth’s crust and upper mantle are broken into sections called plates

• The Earth's outer core is separated into plates and move

• The Earth's crust is one large plate that is fixed in its location

• The Earth's mantle is stationary and forces plates to form on in the crust

What is the Lithosphere?

• Hot bubbling magma under the Earth's crust

• Mountains and other landforms

• The crust and part of the upper mantle

• The only part of Earth's structure that doesn't move

What is the Asthenosphere?

• Magma plumes under volcanoes

• The plastic layer below the lithosphere

• The plastic layer above the lithosphere

• The lower mantle

The 2 Types of Plates are...

• Coastal and Ocean

• Continental and Ocean

• Convergent and divergent

• Transform and faults

What is the theory of plate tectonics?

• Everything on Earth is made up of rock

• Earth's crust is made from material in the inner core

• The Earth's crust is broken up into plates that move upon the asthenosphere

• All of the plates that make up Earth's lithosphere were once one large continent

What are divergent boundaries?

• Plates that move apart from one another

• Plates that move towards one another

• Plates that move along one another

• Dinner plates that don't like each other

What types of landforms occur along divergent plate boundaries?

What are convergent plate boundaries?

• Plates that move towards one another

• Plates that move away one from one another

• Plates that slip and create earthquakes

• Plates that create ocean riffs

 

What types of landforms occur along convergent plate boundaries?

What happens to ocean-continental plates when they collide?
