Earth's Layers
The outermost solid layer of Earth.
What is crust?
The one landmass in which all the continents were once part of.
What is pangaea?
The boundary formed when 2 plates collide.
What is a convergent boundary?
Rocks change shape under stress.
What is deformation?
Any place where gas, ash, or melted rock comes out of the ground.
What are volcanoes?
Hot, slow flowing, solid rock between the crust and the core.
What is the mantle?
Underwater mountain ranges.
What are mid-ocean ridges?
The boundary formed when 2 plates move away.
What is a divergent boundary?
Mountains that are formed when layers are squeezed together and pushed up.
What are folded mountains?
The resistance of a liquid to flow.
What is viscosity.
The center of the Earth; made up of mostly iron.
What is core.
The process used to explain the age and magnetic patterns on seafloor rock.
What is seafloor spreading?
The boundary formed when two plates move past each other horizontally.
What is a transform boundary?
Mountains that are formed when melted rock erupts onto Earth's surface.
What are volcanic mountains?
Location where mantle plume rises through the asthenosphere.
What is a hotspot?
The 2 ways Earth's layers are identified.
What are the compositional and physical layers?
This layer of Earth is divided into tectonic plates.
What is the lithosphere?
Old rock slopes downward away from the ridge.
What is a ridge push?
Mountains that are formed when tension makes the lithosphere break into pieces.
What are fault-block mountains?
Extremely hot mantle rock.
What is a mantle plume?
What is the outer core?
Movement due to differences in density.
What is convection?
At subduction zones, sinking plates pull other plates.
What is a slab pull?
The process that can cause land to rise.
What is uplift?
The name of a hole in a lava field where you can see the lava.
