This Layer of the Earth is the outer most layer, and is the part of Earth that we live on.
What is the Crust?
100
A mound of land that is not as big as a mountian and LESS than 1000 ft high
What is a Hill?
100
The boundry where two plates are moving away from each other (<-- -->) and new crust is created, making a mid-ocean ridge.
What is Divergent/Spreading Boundary?
100
The theory that one giant super continent existed millions of years ago, when all the continents were attached.
What is Pangaea?
100
It is said to have a shape like an ancient shield.
What is a Shield Volcano?
200
This layer makes up 2/3 of the mass of the Earth.
What is the Mantle?
200
Mountains in a row that are connected so that they don't appear to be seperate mountains.
What is a Mountain Range?
200
At this type of Convergent Boundary, two continenal plates are moving toward (--><--) each other, forming Mountians.
What is a Collision Boundary?
200
The scientist that came up with the theory of Continental Drift, and Pangaea.
Who is Alfred Wegener?
200
A type of volcano that has very explosive eruptions, but ejects only ash and cinders, which make up the composition of the steep slopes.
What is a Cinder Cone Volcano?
300
The part of the mantle that is liquid, allowing the molten rock to flow.
What is the inner mantle?
300
A mountain with a hole in the middle where the lava can come out to form a mountain.
What is a volcano?
300
The boundary where two plates rub past each other, causing many earthquakes and a fault.
What is a Transform Boundary?
300
The theory that continents drifted apart in the past, and continue to do so today.
What is Continental Drift?
300
A type of volcano that has very mild eruptions, ejecting mainly lava which flows forming flat gentle slopes.
What is a Shield Volcano?
400
The part of the Core that is solid, due to the amount of pressure from the rest of the Earth.
What is the inner core?
400
The low area between two mountain ranges, usually naturally occuring.
What is a Valley?
400
Where two plates move toward each other, they can be any type of plate pushing against another.
What is a convergent boundary?
400
Strengthening roofs and walls with metal, using shatter-resistant film on windows, and attaching electrical fixtures and bookcases securely to the walls are all good ideas for this.
What is preparing for an earthquake?
400
A steep sided volcano that is made up of alternating layers of ash, cinders, and lava. It also has very explosive eruptions.
What is a Stratovolcano/Composite Volcano?
500
The crust and the solid outer mantle are broken into a dozen plates that make up this.
What is the lithosphere?
500
A low spot between two mountains, usually man made.
What is a Pass?
500
Where two plates are moving toward each other (--><--) but one plate is submerged under the other causing the plate to melt forming a volcano on the surface of the Earth.
What is a Subduction Boundary?
500
The chapter of the book we are learning about right now?
