Earthquakes & Volcanoes
100
By a volcano or inside Earth
Where is igneous rock formed?
100
Sediments are cemented together.
How is sedimentary rocks formed?
100
Occurs where erosion deposits or lays down sediment.
Deposition
100
Shaking of the Earth.
Define earthquake
200
Extrusive- lava cools and hardens Intrusive- magma cools and hardens.
How is igneous rocks formed?
200
Heat and pressure
How is metamorphic rocks formed?
200
Magma- hot, liquid, rock beneath Earth's surface Lava- hot, liquid, rock above Earth's surface.
Magma vs. Lava
200
Several thousands a day Transform boundaries or plate movement that builds up stress forming faults, until rock breaks, and releases stored energy. Carry energy through Earth's interior with P waves (first), S waves and surface waves.
How often do earthquakes occur? What causes it? How do seismic waves carry energy?
300
Granite, Basalt, and Pumice
Name 3 types of igneous rock
300
Deep beneath Earth's surface.
Where is metamorphic rocks formed?
300
The theory proposed by Alfred Wegener that states that the Earth's continents slowly move across Earth's surface.
Continental Drift Theory
300
Volcano - Igneous - weathering - erosion - deposition - sedimentary - metamorphic
Rock cycle! Didn't see that one coming haw?
400
By a water source.
Where is sedimentary rocks formed?
400
Slate, Marble, and Quartzite.
Name 3 types of metamorphic rocks.
400
A giant wave caused by an earthquake on the ocean floor.
Tsunami
400
Volcanoes- Composite, Cinder Cones, and Shield Mountains- Folded, Volcanic, Fault Block, Eroded, and Dome. Eroded is not made of Earth's internal activities.
What is the 3 different types of volcanoes? Mountains?
500
Shale, Sandstone, and Limestone.
Name 3 sedimentary rocks.
500
Sedimentary- By a water source, made with cementing sediments. Metamorphic- Beneath Earth's surface, made with heat and pressure.
Compare and contrast 2 types of rocks.
500
Erosion- carrying away of weathered rock (water, glaciers, waves, mass wasting, wind, and people Weathering- breaking down of rock a) Physical (Mechanical) Weathering- Breaking down of rock by natural forces (Tree roots, frost action- freezing/thawing of water, and animals. b) Chemical Weathering- Changes in rock from a reacction of different chemicals on the surface of a rock (oxidation-rust, lichen, carbonic acid-caves, acid rain-sulfuric acid.
Erosion vs Weathering
