100
The outer layer of the planet earth
What is the crust?
100
A giant supercontinent found on Earth in ancient times.
What is Pangaea?
100
When two plates are pulled apart.
What is tension?
100
The deformational force that causes earthquakes.
What is shearing?
100
The place where magma is stored in a volcano.
What is a magma reservoir (chamber)?
200
Tthe layer of the earth S waves cannot travel through because it is liquid.
What is the outer core?
200
The man who came up with the hypothesis of Pangaea.
Who is Alfred Wagener?
200
When two plates are pushed together.
What is compression?
200
A device used to record p and s wave vibrations from earthquakes.
What is a seismograph?
200
This type of volcano has no lava flows in its interior.
What is cinder cone volcano?
300
The solid inner part of the earth made of very heavy metals like nickel.
What is the inner core?
300
This dinosaur fossil was used as one of Wegener's pieces of evidence for Pangaea.
What is the mesosaurus fossil?
300
When two plates slide past each other.
What is shearing?
300
The 3 major consequences of earthquakes.
What are destruction, fires, and tsunamis?
300
A person who studies vibrations of volcanoes and predicts their eruption.
What is a seismologist?
400
This is used to study the earth's interior because it is too hot to drill into the center of the earth.
What are earthquakes?
400
These bands on the earth's crust line up on the edges of present day continents.
What are magnetic bands?
400
Mountains that are formed when rocks fold upward.
What is an anticline?
400
The location where a majority of all earthquakes occur.
What is the Ring of Fire?
400
The 3 type of volcanic ejecta emitted from an active volcano.
What is solid, liquid, and gas?
500
This occurs when p waves travel through a liquid.
What is refraction (bending)?
500
The process by which scientists believe caused the shifting of continental plates and seven major continents.
What are convection currents?
500
Valley's that are formed when the earth's crust is pulled apart.
What is a syncline?
500
The types of wave that travels faster and arrives at a seismograph first.
What is a P wave?
500
A word that describes lava by how fast it flows and it's thickness
What is viscosity?
