100
The solid center layer of the earth's interior
What is the Inner Core
100
The three types of rocks in the Rock Cycle
What are igneous, metamorphic, sedimentary
100
He proposed the theory of continental drift
Who is Alfred Wegener
100
This is the process that continually adds new material to the ocean floor
What is sea-floor spreading
100
A break in Earth's crust where rocks have slipped past each other
What is a fault (will accept crack)
200
This is a result from a force pressing on an area, and it increases as you go deeper into the Earth.
What is pressure
200
a rock can be changed to _________________rock with heat and pressure.
Metamorphic
200
Name 2 types of evidence that helped support Wegeners theory of Continental Drift
landforms, mountains fossils Jigsaw fit Glacial activity (or similar climatic zones)
200
This is what erupts through the valley of the mid-ocean ridge
What is molten material (magma)
200
Earth's lithosphere (crust) is broken into separate sections called
plates
300
These are the four main layers of the Earth traveling from the outside of the Earth to the innermost part of the Earth
What are the crust, mantle, outer core, and inner core.
300
what forms when rocks get eroded.
sediment
300
Scientists who study the forces that make and shape the planet Earth are called
Who are geologists
300
This is the process by which oceanic crust sinks beneath trenches and back into the mantle
What is subduction
300
This type of boundary is a place where two plates slip past each other
What is a transform boundary
400
This type of rock covers about 75% of the continental crust and is formed in layers
What is Sedimentary Rock
400
What processes turn sediment into sedimentary rock (2 of them)
Compaction and Cementation
400
Fossils of tropical plants found on an island in the Arctic Ocean are evidence for Wegener's hypothesis of
Continental Drift
400
What does Iceland sit on.
Mid-Oceanic Ridge or Mid-Atlantic Ridge
400
What is the boundary called when plates are moving away from each other.
Divergent Boundary
500
Approximately what percentage is the Earth's Crust relative to the other layers. (50, 25, 1, 10)
What is 1%
500
What is a common type of Igneous rock (it is difficult to drill into)
Granite
500
The reason scientists rejected Wegener's theory was because he could not do the following
What is explain what force pushed or pulled the continents
500
What lies beneath Hawaii, creating volcanic activity
Hot Spots in the earths crust
500

What are spreading boundaries (divergent), colliding boundaries (convergent), and sliding boundaries (transform)
