The three layers of Earth, from the center to the outside, are:
What are core, mantle, crust
100
This landform is a very high hill with steep, rocky sides.
What is a mountain.
100
The area of volcano and earthquake activity around the Pacific Rim is called the _______ of ______
What is the Ring of Fire.
100
Weathering and erosion happen on these places, also known as the seven large land masses on Earth.
What are continents.
100
This is the huge land mass that existed 200 million years ago. (when all continents were connected)
What is Pangaea.
200
This is the thinnest layer of Earth.
What is the mantle.
200
Plateaus are landforms that are like hills with flat tops: true or false.
True.
200
When new crust forms where magma rises at mid-ocean ridges, this is known as: continental drift, mass movement, ocean-floor spreading.
What is ocean-floor spreading.
200
This is the process of breaking down rocks into smaller pieces.
What is weathering.
200
This force changes Earth most slowly: earthquake, volcano, landslide, erosion.
What is erosion.
300
This is the hot, flowing rock below Earth's surface.
What is magma.
300
This is the opening in Earth's crust through which melted rock (lava) reaches the surface. **Tricky question: think explosion.
What is a volcano.
300
This is what a crack in Earth's crust is called.
What is a fault.
300
This is not weathering or erosion, but it's still important.
Subduction occurs when... a glacier cuts grooves in Earth's crust, two plates collide and one slides under the other, or fossils are buried beneath the layers of sedimentary rock.
What is when two plates collide and one slides under the other.
300
This is the purpose of the rock cycle model.
What is to show how rocks form and change.
400
These are the sheets that cover Earth's surface, made up of the crust and upper mantle.
What are plates.
400
This area of landforms is the NOT a common place for earthquakes: faults, mid-ocean ridges, polar regions, where plates meet.
What are polar regions.
400
This instrument measures the strength of an earthquake.
What is a seismograph.
400
Weathering and erosion are forces that change the earth very ___________.
What is slowly.
400
This is the vocabulary term that refers to rapid back and forth movement.
What is vibration.
500
This the reason people sometimes believe, or say, that the Earth actually has 4 layers, instead of 3.
Because the core is made up of two parts: inner core and outer core.
500
If you find one of these imprints or remains of an organism that lived long ago preserved in the rock of a mountain, you have probably found this.
What is a fossil.
500
This is the place in Earth where the energy of an earthquake is first released.
What is the focus.
500
Deposition occurs when: rocks are broken into pieces, a landform is worn away by wind, water, and plant roots, or when bits of rocks are dropped by a glacier.
What is when bits of rocks are dropped by a glacier.
500
The reason plates are always moving is because of this: glacial deposits, seismic waves in the core, convection currents in the mantle, or Earth's rotation on its axis.
