More Plates
100
All of the continents as one land mass many years ago.
What is Pangaea??
100
This is the part of the earth that is like the top layer of a pie. It is the rocky part.
What is the crust?
100
This area in the earth's crust is where a volcano could form.
What is a weak spot where magma is forced up under pressure?
100
When two plates rub together at a fault this occurs.
What is an earthquake?
100
The pull of the earth's core that can pull plates under by subduction.
What is gravity?
200
The Earth's crust and upper mantle are broken into sections called this.
What are Plates?
200
The crust and upper mantle together.
What is lithosphere?
200
These determine the type of eruption a volcano will have.
What is temperature and the type of rock that makes up the magma?
200
A break or crack in rocks where the earth's crust can move.
What is a fault?
200
The direction of convection currents that would cause plates to converge.
What is toward each other?
300
A mountain is formed when 2 plates crash together or this type of boundary.
What is a converging boundary?
300
The mantle is a thick liquid part under the crust that moves because of this heating and cooling motion.
What are convection currents?
300
When volcanoes make (build) new land they are considered this.
What is constructive?
300
The place underground where the earth's plates stick and grind.
What is the focus?
300
The direction of plate movement during an earthquake.
What is sliding past or transform?
400
An earthquake occurs when 2 plates slide past each other or this word that also changes.
What is transform ?
400
The dense liquid of the mantle moves downward toward the core when it does this.
What is cools off?
400
Lava is this spewing out of a volcano and magma is this same material still under the earth's crust.
What is liquid mantle or molten rock?
400
When earthquakes happen under the ocean these occur.
What are tsunamis?
400
The type of plate movement when subduction occurs.
What is converging?
500
Seafloor spreading or rift valleys form because of this plate movement apart from each other.
What is divergent?
500
This is the plasticlike layer beneath the lithosphere that the plates float on.
What is asthenosphere?
500
This climate change can occur as a result of a volcano.
What are cooler temperatures, more cloudiness and more precipitation?
500
The surface of the earth above the focus.
What is an epicenter?
500
A trench can form when these two types of crust meet. Subduction often happens here.
What is oceanic and continental?
