100
What two features does the geosphere include INSIDE the Earth?
solid and melted rock
100
When plates move, what can occur as a result?
mountain building, earthquakes, and volcanoes
100
Where do volcanoes form?
on land & ocean floor
100
What is a landslide?
a sudden movement of a large amount of rocks and soil down a slope
200
What is the Earth's rocky outermost layer?
the crust
200
The Himalayas are what type of mountain?
folded mountain
200
According to scientists, where do volcanoes tend to erupt?
where one plate is pushed under another plate
200
What are minerals?
solid, nonliving substances found in nature
300
Which layer is made up partly of molten rock?
mantle
300
Give an example of mountains that are fault-block mountains.
Sierra Nevada Mountains
300
What happens to the plate that gets pushed down under the other?
The plate will melt due to the extreme heat and pressure, forming magma.
300
What happens to the ground (on a slope) when it can no longer hold in water from heavy rains?
it can flow down the slope and knock down trees and destroy whatever is in its path.
400
What is the core? What is it made up of?
The core is the deepest layer of Earth at the center. It is very hot, solid rock made mostly of iron.
400
How are folded mountains formed?
When Earth's plates are pushed together, the crust is forced upward, which produces folded mountains.
400
When will magma rush towards the Earth's surface (erupt)?
(1) a crack may form above the lava chamber, or (2) the pressure inside the chamber will be too strong to be kept in
400
What can cause a landslide?
earthquake vibrations, human activity, heavy rains, volcanic eruptions
500
What is the order of the Earth's layers from the outermost to the deepest?
crust, mantle, core
500
How are fault-block mountains formed?
One side of the Earth's continental boundary moves up and other side moves down.
500
What is the difference between an active, dormant, and extinct volcano?
Active volcanoes may have recently erupted or is currently erupting.
Dormant volcanoes haven't erupted for a while, but may erupt in the future.
Extinct volcanoes that are believed to not erupt again.

Most of the US is covered by one of these three types of soil
different colors, sizes, behave differently when water is added
