What does Ga mean? - correct answer Billion years ago
What is planetary accretion? - correct answer Dust and ice begin to collide, building
bigger and bigger objects. (ex. Meteors striking the Earth)
About how long ago did Earth come together? - correct answer 4.5 Ga
Does planetary accretion still happen? - correct answer Yes! The rate is just slowed
down.
,What is the Theia Impact? - correct answer 50 mil yrs into Earth's existence and Earth
collides into another planet the size of Mars called Theia.
What two things happened due to the Theia impact? - correct answer 1. Lunar
Formation of Moon
2. Earth became a molten planet
What happened when Earth was a molten planet? - correct answer Since a lot of the
rock was magma or lava it allowed the Earth to stratify based on density. This is why
Earth has different layers. The layers then re-solidified and this is why they have
different densities.
What does Ma stand for? - correct answer Million years ago
,Explain what the Popigai Crater is in Russia, when it happened, and why it is special. -
correct answer The Popigai crater in Russia is 100km wide and occurred about 35 Ma.
It was caused by a 5 - 8 km asteroid. It is special because the diamonds in the crater
have been found to have some of the best quality in the world.
What are the four Compositional Layers of Earth? - correct answer 1. Crust
2. Mantle
3. Outer Core
4. Inner Core
What is the range of the crust and what is it made out of? How many different "crusts"
are there? - correct answer The crust ranges from 8 - 45km deep and is made out of
lighter elements (Silicon, Aluminum, mainly Oxygen). There are 2 separate forms of
crust. Continental crust (lighter crust) and Oceanic crust (denser crust).
, What is the range of the Mantle and what is it made out of? - correct answer The
mantle ranges from 45 - 2,900 km and is made out of denser elements ex.(Magnesium
and Iron)
What is the outer core made of? - correct answer Mostly iron and nickel
What is the inner core made of? - correct answer 94% Iron and 5 - 6% Nickel both
solid.
What are the mechanical layers of the Earth? - correct answer 1 - Lithosphere
2 - Asthenosphere
3 - Mesosphere
4 - Outer Core
5 - Inner Core
