The cool, outer shell of the earth. It consists of the crust and the rigid uppermost part of the mantle. It is broken up into segments or plates.
What is the lithosphere?
100
The type of boundary where the two plates are grinding against each other.
What is a Transform Boundary?
100
The rate that the earth's plates move can be compared to the rate that this grows.
What is a human fingernail?
100
The outermost layer of the earth.
What is the crust?
200
The solid ball of iron and nickel at the center of the earth.
What is the inner core?
200
At this type of boundary, large mountain ranges form, but there are rarely volcanoes (include the type of plates that are colliding).
What is a Convergent Boundary of two continental plates?
200
The name of the most famous fault line, located along the western coast of the United States.
What is the San Andreas Fault?
200
The area around the edges of the Pacific Ocean where most of the world's earthquakes and volcanoes occur.
What is the Ring of Fire?
300
The thickest, solid layer of the earth. It makes up 83% of the earth's interior.
What is the mantle?
300
This boundary forms from two plates drifting apart from one another. As they move apart, magma moves up, cools, and builds onto the plates forming a ridge.
What is a Divergent Boundary?
300
Whenever a plate slides under another at a convergent boundary, it because the plate that goes under has this.
What is greater density?
300
The "supercontinent" that made up all of earth's land masses 250 million years ago.
What is Pangea?
400
The layer of the earth that is made up of liquid iron.
What is the outer core.
400
At this type of boundary, one plate slides under the other, causing volcanic mountain ranges to form along the edge of a large land mass (include the types of plates colliding).
What is a Convergent Boundary of one oceanic plate and one continental plate.
400
Along with the shape of the continents, scientist used these two types of evidence to support their theory of plate tectonic and the existence of Pangea.
What are mountain ranges and fossils of plants and animals?
400
The geographical feature formed as a result of divergent plate boundaries separating and expanding.
What is a ridge?
500
The layer of the mantle that lies directly below the lithosphere and flows like taffy.
What is the asthenosphere?
500
This type of border involves one plate sliding under another plate resulting in a string of volcanic islands (include the types of plates colliding).
What is a Convergent Boundary of two oceanic plates?
500
The reason that scientists know that outer core is liquid.
What is that s-waves do not travel through the outer core?
500
The geographical feature formed right at a convergent boundary where one plate is sliding under another.
