Plate Tectonics
Explain the movement of a divergent boundary & what forms?
move apart/ Mid-ocean ridge, rift valley
How would Coal found in Antarctica provide evidence that climates on earth have changed over time?
Coal only forms in warm swamp areas unlike the Antarctica climate we know today, so it must mean Antarctica was once near the equator producing coal.
What mischievous character makes pranks from the day after Thanksgiving to Christmas Eve?
Elf on the shelf
What is the difference between extrusive and intrusive rocks
Intrusive: cools slowly, large grain size, inside volcano
extrusive: cools quickly, small grain size, exits volcano
As carbon dioxide emission rises, what happens to Global temperature
it rises
Explain the movement of a transform boundary & what forms?
slide, Earthquake
Give four pieces of evidence to support the theory of continental drift.
1) jigsaw fit
2) fossils of same species found on different continents
3) climate evidence
4) rocks & mountains fit across continents
How many towns in America are named “Christmas”?
Two (Christmas, Michigan and Christmas, Florida)
there was once a rock that started as a extrusive igneous rock, then became a sedimentary rock, and now is a metamorphic rock. What process in order did the rock go through.
WEDS to form sediment. sediment compact and cements to form a sedimentary rock. The sedimentary rock is exposed to extreme heat and pressure to become a metamorphic rock.
What is conservation and list the three R's?
Conservation means to save
three R's: Reuse, Reduce, Recycle
What type of boundary moves towards each other?
List what forms:
convergent
Mountains, volcanic islands, volcanic mountains, deep ocean trench
Label the diagram below in terms of temperature and density. Word Bank: Magma cools off and sinks, Magma heats up and rises, less dense, more dense, warm, cool
Cool = more dense (sinks)
Warm= less dense ( rises)
What holiday drink is also called “milk punch”?
Eggnog
What forms Igneous, Metamorphic, and sedimentary Rocks
Igneous: Cooling & Hardening
Metamorphic: Heat & Pressure
sedimentary: Compact & cement
Make a T-chart sorting renewable vs non renewable energy sources.
draw a star next to the ones with pollution.
Nonrenewable: coal (p), oil (p), natural gas (p), nuclear
Renewable: solar, wind, water, biomass (p), tidal, geothermal
What does subduct mean?
include: type of boundary & type of crust
At convergent plate boundaries denser Oceanic crust sinks beneath continental crust.
Label each layer based on their temperature and density.
1) outer core
2) crust
3) inner core
4) mantle
Which two of Santa’s reindeer names come from weather phenomena?
Donner (thunder) and Blitzen (lightning)
What properties are used to identify minerals? List five or more
Color
Luster
Streak
hardness
density
cleavage/fracture
In the United States, fossil fuels are our main energy source; however, this use has a negative impact on the environment. Describe how fossil fuels affect the environment. (What do they increase?)
Increase greenhouse gasses like CO2, trapping extra heat causing global warming.
Other answers: sea level rise, smog, more server storms, droughts
What is happening in the mantle to move Tectonic Plates?
Convection Currents!!
As we go deeper into the earth, What happens to temperature, density, and pressure?
They all increase!!
Which U.S. President made Christmas a federal holiday?
Ulysses S. Grant
What is a mineral? List the 5 characteristics (SNIFC)
Solid
Naturally occurring
Inorganic
Fixed composition
Crystalline Structure
Explain the greenhouse effect. What are the three main gasses?
gasses in atmosphere absorb heat from the sun, warming the planet.
Three main: Methane, CO2, Water vapor
