Vocab
The thick layer of Earth beneath the crust.
mantle
The point on Earth’s surface directly above the focus of an earthquake.
epicenter
Nonexplosive lava flows
Shield volcano
Which land feature forms where two continental plates move toward each other?
Mountains
True or False: The temperature of Earth gets colder the closer you move toward the core.
False
The theory that Earth’s crust is divided into plates that are always moving.
plate tectonics
A break in Earth’s crust where rock on one side moves in relation to rock on the other side.
fault
explosive eruptions; Lava explodes into the air and quickly hardens.
cinder volcano
Which land feature forms where two plates pull apart from each other
rift/seperation
Would a city or the country have more damage in an earthquake?
city
The shaking of Earth’s surface that can cause land to rise and fall.
Earthquake
The layer of Earth extending from Earth’s center to the bottom of the mantle. It is mostly metallic iron and nickel
core
Explosive eruptions produce the steeper slope, and liquid lava flows cement the fragments in place.
composite volcano
What can occur when two plates slide past each other?
Earthquake
What happens to the waves as you move away from the focus?
The waves get weaker, less energy
The thin outer layer of Earth including dry land and the ocean floor.
crust
How many plates make up the Earth?
About 10

What layer of the earth does an earthquake begin?
Crust
How much more energy is released by an earthquake of magnitude 4 than one of magnitude 2?
961
A place where hot gasses, smoke, and melted rock come out of the ground onto Earth’s surface.
Volcano
What type of landform can form the most quickly?
Volcano

What does a seismograph measure?
the size of energy waves
How do the Richter scale and the moment magnitude scale compare?
Richter scale- measures energy of an earthquake on a scale of 1 to 10
MMS- measures the magnitude of the earthquake
