What is a convergent boundary?
When two plates collide.
100
What is the difference between magma and lava?
Magma is inside a volcano and lava is outside
100
What type of wave causes the most damage?
Surface Waves.
100
What is a rock made of?
Minerals
100
What unsustainable fuel is widely burned to generate electricity?
Coal
200
What is a divergent boundary?
When two plates separate.
200
What is a glass-like rock that forms as a result of rapidly cooled lava?
Obsidian.
200
What is the Epicenter?
The point on the crust directly above the origin of the earthquake.
200
What type of rock contains most fossils?
Sedimentary
200
Name 3 common forms of alternative energy.
Solar, Wind, Geothermal, Hydroelectric, Tidal
300
What is a transform boundary?
When two plates slide past one another.
300
What is the difference between a dike and a sill?
Dikes run vertically whereas sills run horizontally. (Both are igneous intrusions inside the volcanoes)
300
What is the Focus?
The point in the Earth where the earthquake originated from.
300
Name the three kinds of rocks we talked about (Hint: we demonstrated these stages through compressing and melting crayons)
Sedimentary, Igneous, Metamorphic
300
Name 2 gases that contribute to global warming.
Carbon Dioxide, Methane, Water Vapor, Nitrous Oxide (Laughing Gas), Ozone (O3)
400
What happens when two oceanic plates converge?
The older, more dense plate goes under the younger one.
400
What are 3 things that are released during the eruption of a volcano?
Lava, Nitrogen, Sulfur Dioxide, Carbon Dioxide, Pumice, Ash
400
What instrument do scientists use to gauge the magnitude of an earthquake?
Seismograph
400
What two forces contribute to form metamorphic rocks?
Heat and Pressure
400
Name 3 small changes can you make to your daily routine at home to be more sustainable?
Turn off lights when leaving a room, take shorter showers, read a book instead of watching tv, wash dishes by hand instead of by machine, fix leaky faucets, unplug things when not in use(use power strips), etc.
500
What two plates does California sit on?
The North American Plate and the Pacific Plate.
500
Where do volcanoes form?
Usually in areas right above subduction zones. The melting that occurs as one plate is pushed under the other plate creates the volcanoes.
500
What kind of energy is released in a tsunami?
Elastic Strain/Potential Energy
500
When a rock cools underground, what can you say about its' rate of cooling and subsequent grain size? a) It cools quickly and has big, visible grains. b) It cools quickly and has small, finer grains. c) It cools slowly and has big, visible grains. d) It cools slowly and has small, finer grains.
c) It cools slowly and has big, visible grains (No air to cool it quickly and has a lot of time to form solid grain structures. Ex: Granite)

Name 3 negative effects of mountain top removal mining.
Mountain is destroyed, Surrounding area gets buried, underground water becomes polluted, nearby species are displaced and lose habitat
