Earth's Layers
What is the outer layer of the Earth.
The Crust
What causes earthquakes
Tectonic plates
Tectonic plates moving/ when tectonic plates shift
melted rock underground.
Magma
Tsunamis are caused by this type of earthquake.
Underwater Earthquakes
This tool records earthquake shaking.
seismograph
What is the layer is directly under the crust.
The Mantle
This is a crack where plates move.
Fault line
magma that reaches the surface.
Lava
Tsunamis are large ______ in the ocean.
Waves
This scale measures earthquake strength.
Richter scale
What core layer is liquid
The Outer Core
This is where earthquakes happen most often.
Plate Boundaries
What happens when magma rises to the surface?
It becomes lava and can erupt from a volcano
Why do scientists place sensors on the ocean floor?
To detect earthquakes and movement underwater.
What are all the tools that measure earthquakes.
Seismograph and Richter scale
What is the hottest layer of the earth
The Inner core
This is the point on Earth’s surface where an earthquake begins
The Epicenter
Name one danger of a volcanic eruption.
Lava flow / gas / destruction
How do sensors help keep people safe?
They send warnings so people can evacuate.
hese move slowly and cause earthquakes.
tectonic plates
Plate tectonics
The Earth’s crust is broken into these moving pieces.
Tectonic Plates
Why do earthquakes happen near plate boundaries.
When plates push pull , or slide past each other.
(Convergent, Divergent, Transform)
Explain the difference between magma and lava.
Magma is underground, lava is on the surface.
Give one reason why early warnings are important.
They give people time to move to safety and avoid danger.
