Layers
This is the outermost layer of earth.
What is the Crust?
This type of cloud is made of bits of rock that are spewed out from the volcano upon eruption.
What is an ash cloud?
Earth's inner core is made of this.
What is solid iron?
This happens to Earth's magnetic field about every 500,000 years.
What is, it reverses?
Plates slide past each other at this type of boundary.
What is a transform boundary?
This is what the center of the Earth is called.
What is the core?
This is the bow-shaped depression at the top of a volcano.
What is the crater?
These make up the lithosphere.
What are the crust and upper mantle?
This is the area where plates meet.
What is a plate boundary?
Volcanoes often form at plate boundaries for this reason.
What is, because plates can slide beneath each other?
The Earth's mantle is in this form or state.
(Hint: Think solid, liquid, gas, or a combination of two or more)
What is solid and liquid?
This is molten rock that has erupted out of the volcano and is flowing down the side.
What is lava?
This is how one would best describe Pangaea.
What is an ancient super continent?
To support his theory of continental drift, Wegener used these.
What are fossils?
A huge break in the crust of the Earth is called this.
What is a fault?
This is where the mantle layer is located.
Where is beneath the crust?
This is what the molten rock is called when it is still in the reservoir beneath the volcano, and in the conduit, a pipe that leads from the reservoir to the crater.
What is magma?
Evidence that can be observed using your five senses is called this.
What is empirical evidence?
Newly formed crust on the ocean floor that pushes old crust apart best explains this Earth action.
What is sea-floor spreading?
This is where you would find the crater of a volcano.
Where is the top?
On dry land, the Earth's crust is about this thick.
What is 25 miles?
Not to be confused with a parasitic cone (like a mini-volcano cone on the bigger, main volcano cone), this is an opening on the side of a volcano out of which lava flows.
Sometimes this is part of the parasitic cone, but not always.
What is a side vent?
An idea that provides an explanation for an observation is called this.
What is a scientific theory?
Plates move away from each other at this type of boundary.
What is a divergent boundary?
This is a structure that can form on the side of a volcano, kind of like a mini volcano cone.
What is a parasitic cone?
