What are all the planets of our solar system in order?
Alfred Wegner. Earth's continents were once joined together in a single supercontinent called Pangea.
Who was the guy who came up with the Plate Tectonics theory? What was the theory?
What is 1 type of rock?
Sedimentary, Metamorphic, Igneous
What time were the Dinosaurs around?
Revolution is when the earth orbits around the sun and rotation is when the earth is spinning on its axes.
What is the difference between revolution and rotation?!
4.6 billion years ago
How long ago did our solar system form?
What is evidence that supports Pangea?
Name 1 part of the rock cycle (NOT what causes the change, no cooling/melting etc.)
Igneous rock, Sediment, Sedimentary rock, Metamorphic rock, Magma.
Name 1 Era.
Paleozoic, Mesozoic, Cenozoic.
New Moon, Waxing crescent, First quarter, Waxing Gibbous, Full moon, Waning Gibbous, Last quarter, and Waning crescent.
What are the moon phases in order? (Light from the right to the left)
A cloud of dust and gas collapsed and gravity pulled materiel to the center to form the sun. The leftover materiel formed a rotating disk around the sun.
What is the solar nebula hypothesis?
What is the outer and inner core composed of?
Iorn and Nickle

A solar eclipse is when the moon passes between the earth and the sun, and the moon's shadow fall on earth.
A lunar eclipse is when the earth passes between the sun and the moon and the earth's shadow falls on the moon.
What is the difference between a solar eclipse and a lunar eclipse? Where does the shadow fall on?
Dust coagulation, Pebble formation, Concentration and clumping, Gravitational instability, and collision based growth
What are the steps for Planetesimals
What does the magnetic field from the outer core protect us from?
Solar radiation.
What's the difference between Extrusive and Intrusive Igneous rocks?
Intrusive Igneous rocks cool slowly over time in the Earth's crust. Extrusive cool quickly on the surface.
What Eon did Earth form?
Hadean Eon.
Spring tides occur when the earth, moon, and sun align during new moons and full moons
Neap tides occur when the earth, moon, and sun make a right angle during the 1st and 3rd quarter moon phases
When do Spring tides and Neap tides occur?
Earth nebula collapse, Planetesimals, Proto-earth growth, Differentiation, Heavy bombardment
What are the two types of seismic waves? And how do they move.
P-waves and S-waves. P-waves move like slinky and S-waves move like a gym rope.
Give each rock the correct type: Sandstone, Slate, Obsidian
