100
The earth spins once in how many hours?
What is 24
100
What is oceanic crust?
What is crust found under the Earth’s oceans and is denser due to compression from water.
100
What is a fault zone?
What is cracks that occur when plates move.
100
What is a volcano?
What is any structure that brings magma from below the surface, erupting lava on the surface.
100
What is an intrusive igneous rock?
What is rocks that formed underground.
200
The imaginary line that runs through the North & South pole is known as what?
What is axis.
200
What is continental crust?
What is crust found on land and is less dense due to less pressure.
200
What is the Ring Of Fire?
What is the nickname of the region bordering the Pacific Ocean where 80% of all earthquakes occur.
200
What is an ash cloud?
What is a cloud of volcanic ash and dust when a composite volcano erupts
200
What is an extrusive igneous rock?
What is rocks that formed above ground like a volcanic eruption.
300
What is the layer of the Earth that is made of both solid and liquid?
What is mantle.
300
What is a lithosphere?
What is the rigid crust and upper mantle that sits on top of the asthenosphere.
300
What are primary waves?
What is waves that move faster than secondary waves and are compressional waves. Their energy similar as to the one that moves through a slinky
300
What is viscosity?
What is "thickness", a fluid's ability to reist flow.
300
What is cementation in sedimentary rocks?
What is "gluing" sediments together.
400
What shape is the Earth?
What is oblate spheroid?
400
What is the Asthenosphere?
What is the molten material below the lithosphere which causes plates to move.
400
What are secondary waves?
What is waves that move slower than primary waves and are shear waves. They move similar to energy through a rope.
400
Where is the magma chamber located?
What is underground chamber in the earth's crust.
400
How does a metamorphic rock form?
What is intense heat and pressure underground.
500
What is a hypothesis?
What is a prediction based on an observation.
500
Heated material in the asthenosphere rises and sinks as it becomes hotter and colder, this causes the plates above to move. This is known as what?
What is Convection Currents.
500
What causes an earthquake?
What is transform and convergent (subduction) boundary plates moving past each other cause stress to build up and then release energy.
500
In what state did Mt. St. Helens erupt in?
What is Washington State.
500
What are the five characteristics of all minerals?
What is solid, inorganic, occur naturally, orderly crystalline structure, & same chemical composition.
