What is weathering?
Weathering is to break down into smaller pieces with natural processes
100
How does an earthquake occur?
Sudden shifts in tectonic plates cause earthquakes
100
What is a seismograph?
A seismograph is a tool used to track the seismic wave movement through the earth
100
What do you call the material inside a volcano/outside a volcano?
Inside: magma
Outside: Lava
200
How are sedimentary rocks created?
They are created by putting pressure on smaller sediments over time to create a singular rock
200
What is erosion?
Any process or force that moves sediments to new locations
200
What causes tsunamis?
Underwater earthquakes/shift in plates underneath the ocean can cause tsunamis?
200
What are the two different kinds of weathering?
Chemical Weathering and Physical Weathering
200
What is the rock cycle?
The rock cycle is the continuous cycle in which rocks are created, destroyed and recreated
300
How are metamorphic rocks created?
They are created by taking other kinds of rocks and applying enough heat to change their minerals, but not enough to turn them into magma.
300
What are hydrothermal vents?
deep sea geyser that releases extremely hot and mineral-rich water through the cracks of the earth
300
How do volcanic eruptions occur?
Volcanic eruptions are caused by a change of pressure in the magma chamber pushing the magma up and out of the volcano.
300
What are the 3 different kinds of mountains?
Dome mountains, fold mountains, and fault-block mountains

Who was Alfred Wegener?
He is the man that hypothesized the continental drift. He did not have evidence to support it at first and people did not agree with his ideas.
400
How are igneous rocks created? Why do the mineral pieces look larger or smaller?
Igneous rocks are created from magma coming up from the earth's mantle. The minerals are different sizes because of how fast they were able to cool. Fast cooling = small minerals, slow cooling = large minerals
400
The study of earth, how it changes, and its processes is called what?
Geology

Give an example of how cultures explain how natural disasters occur.
Pele and her sister stealing her lover explains volcanic eruptions.
The crow carrying the whale to the mountain top explains earthquakes.

What can you often find in sedimentary rock that can show us what kind of animals used to be on this earth?
Fossils
400

500
Name a type of sedimentary rock.
Limestone, sandstone, shale

What is subduction zone?
The subduction zone is where one plate moves under another plate.

Name three volcanoes we learned about.
Bonus 100 points if you name the island Mr. Rock talked about yesterday.
Yellowstone, Tambora, Mauna Loa, Vesuvius
Bonus: Westman Island
500
The explanation for the moving, sliding, and shifting under the earths crust is called what?
Plate tectonics

What is Pangea? What are the names of the continents that made it up?
Pangea is the supercontinent that existed before all the seven continents were separated. The seven continents are North America, South America, Europe, Africa, Asia, Australia, and Antarctica.
