Solar System Formation
The four basic steps of the formation of the solar system.
What are: molecular cloud, solar nebula, sun formation, planet formation?
The energy from ongoing collisions caused the Earth to heat up leading to this process, that created Earth's layers.
What is differentiation?
These are the four layers of the Earth.
What is: crust, mantle, outer core, inner core?
Is the following an observation or inference:
The tree grew 120 years ago.
Inference
These 2 things are at the core of gas giants.
What are rock and ice?
Before the solar system began to form, it was in the form of this.
What is a molecular cloud?
This is the difference between meteors and meteorites.
What is: meteors are in Earth's atmosphere, and meteorites are on Earth's surface?
Seismic waves that travel fastest, are compression waves, and can travel through both liquids and solids.
What are P-waves?
This is the name of this graphing relationship:
What is static?
This is the changing of a waves speed, resulting in a change of angle.
What is refraction?
This is the name of the form the solar system was in after the molecular cloud collapsed and began to spin.
What is a solar nebula?
These are 5 major pieces of evidence scientists use to investigate the age of the Earth.
What are crustal rocks, lunar rocks, impact craters, and radiometric dating.
These are the areas seismic waves do not reach due to interference or wave refraction.
What are shadow zones?
This is the variable that a scientists manipulates directly to observe the affect on another variable.
What is the independent variable?
These are the 2 primary elements found in Earth's core.
What are iron and nickel?
Nuclear fusion is the combining of this element into this other element:
What is hydrogen into helium?
Evidence indicates this event occurred approx. 4 billion years ago, involving countless collisions with asteroids, comets, and other objects.
What is Late Heavy Bombardment?
This is what a diamond anvil cell does.
What is squeezes material to replicate pressures found in Earth's interior?
This is how many meters are in 4 kilometers.
What is 4000?
This is what a P wave does at the boundary between the outer and inner core.
What is speeds up?
Once nuclear fusion began in the Sun's core, it began to emit these 3 things.
What are light, heat, and solar wind?
This is the half life of the element represented by this graph:
What is 5730 years
This is the reason we know Earth's outer core is liquid.
What is, S-waves stop abruptly at the boundary between the mantle and outer core (cannot travel through)
This number in scientific notation:
567
What is 5.67 x 102?
This is a high pressure lab device, used to replicate the pressure at the center of the Earth.
What is a diamond anvil cell?
