Earthquakes
Where do most earthquakes happen? (not a specific place but in general)
Fault lines/boundries
If a volcano does not erupt for a long time, we call that volcano to be...
Dormant
Igneous rock is formed by the cooling of.....?
Magma
Which kind of waves create most damage during Earthquakes
S wave
What is erosion
The movement of rocks or sediments
What is an epicenter?
The location on the earth surface directly above the focus
What type of volcano is the most common?
Cinder cone
The the breakdown of rock due to rain, wind, ice, sunlight, and plants is called?
Weathering
Rocks melting into magma
Erosion happens most commonly by (2things)
Wind and Water
How is the energy transferred through the Earth’s crust? (as in what form of energy)
Waves
Volcanoes with a gentle slope was formed by what kind of lava?
Basaltic lava
What is the name given to rock formed from the cooling of molten rock below Earth’s surface.
intrusive igneous rock
Which type of volcano had the most violent eruptions?
Composite
A deposition is when the sediments...
Settles in a place and stop moving.
What scale is used to measure the magnitude of an earthquake?
Richter Scale
What is the most destructive part of a volcano eruption?
Pyroclastic flow
This type of rock is formed from sediments, organic remains, or chemical precipitates.
sedimentary rock
What did vinegar on chalk represent?
Acid Rain (Chemical Weathering)
What is delta?
Deposition of sediments in the mouth of a river
Draw a P wave and an S wave and tell me which one does more damage. (60 seconds)
P wave is longitudinal S wave transverse and does more damage
What is the difference between lava and magma
Magma is molten rock beneath the earths surface and lava is molten rock once it erupts onto the earth surface
Rock that has been formed by immense heat and pressure is called?
Metamorphic Rock
After there has been an earthquake why are 3 seismic reading stations needed to locate the epicenter?
To triangulate the position. Stations can use the data the get from the waves of a earthquake to make a circle. Where each stations circle overlaps is the epicenter
Water current that flows parallel to the shoreline.
It carries sediment that can change the size and shape of the beaches.
