Earth's Layers
Earth is made up of several different layers, each consisting of several different materials that have different characteristics that vary for each layer.
What is inside Earth?
This person proposed the idea of continental drift (plate tectonics) in the late 1800s-early 1900s.
Who is Alfred Wegener?
The process by which rocks shape when under stress.
What is deformation?
Any place where, gas, ash, or melted rock come from out of the ground.
What is a volcano?
Ground movements that occur when blocks of rock in Earth move suddenly and release energy.
What is an earthquake?
Crust, mantle, core.
What are Earth's compositional layers?
A large landmass of all the present-day continents 245 million years ago.
What is Pangaea?
The amount of force per unit area that is placed on an object.
What is stress?
Volcanoes that haven't erupted for a long period of time.
What are dormant volcanoes?
A break in Earth's crust along which blocks of rock move.
What is a fault?
Lithosphere, asthenosphere, mesosphere, outer core, and inner core.
What are Earth's physical layers?
Large scale movements of Earth's lithosphere.
What is the theory of plate tectonics?
Synclines and anticlines.
What are the 2 kinds of folds?
The resistance of liquid material to flow.
What is viscosity?
Earthquakes happen at plate boundaries.
Where do earthquakes happen?
On the lithosphere.
Where are tectonic plates located on Earth's physical layers?
Parts of the lithosphere.
What is a tectonic plate?
Strike-slip, normal, and reverse.
What are the 3 fault types?
Divergent and convergent boundaries; hot spots.
Where do volcanoes form?
Tsunamis, mass building damage, deaths, and billions of dollars lost.
What are some effects of earthquakes?
Solid.
What state of matter is the inner core?
Mantle convection, slab pull, and ridge push.
What causes tectonic plates to move?
Folded, volcanic, and fault-block.
What are 3 kinds of mountains?
Shield, cinder cone, composite volcanoes; lava plateaus, volcanic craters, calderas, and magma chambers.
What are the kinds of volcanic landforms?
The return of rock to its original state after deformation
What is elastic rebound?
