It's an Expanding Subject
It is the correct branch of science dedicated to studying the deep history, overall structure, and ultimate fate of our entire Universe.
What is cosmology?
Compared to our middle-aged Sun, ancient first-generation stars were extreme, possessing these two specific structural traits.
What are larger in mass and hotter?
He caused quite a stir during the Renaissance by correctly asserting the heliocentric model, which states that Earth actually orbits the Sun.
Who is Nicolaus Copernicus?
This is the hot, melted fluid term used for liquid rock when it is trapped completely underground, hidden away beneath Earth's surface.
What is magma?
Earth's dynamic magnetic field behaves just like a giant bar magnet, meaning it possesses this two-pole configuration.
What is a dipole?
Our home sweet home, it is the specific name of the grand spiral galaxy that our Sun belongs to.
What is the Milky Way?
Located safely at letter "D" in the center of an atomic diagram, it is the dense cluster where you will find all of an atom's protons and neutrons.
What is the nucleus?
Grouped together because they are massive and made almost dominantly of gas and volatile materials, these four celestial bodies make up the Jovian planet squad.
What are Jupiter, Saturn, Uranus, and Neptune?
When sorting rock compositions by density, this is the correct order from the fluffiest, least-dense rock type to the absolute heaviest, most dense.
What is felsic, intermediate, mafic, and ultramafic?
If you were to weigh the entire Earth on a giant cosmic scale, you would find that oxygen, silicon, and magnesium are incredibly heavy hitters, but this element takes the crown as the most massive of all.
What is iron?
This fundamental theory argues that our Universe isn't sitting still, but is continually growing and expanding outward.
What is the Expanding Universe theory? (Accept: The Big Bang theory)
If you superheat matter to the point where frantic electrons are violently stripped away from their atomic nuclei, you form this ultra-hot state of matter.
What is a plasma?
If you look at the solar system edge-on, you'll notice all the planets travel along this flat, identical orbital highway.
What is the ecliptic plane?
While the crust and mantle boundary is sorted strictly by what they are made of, the lithosphere and asthenosphere boundary is sorted strictly by this mechanical trait.
What is their ability to flow? (Accept: rigidity vs. plasticity, or mechanical strength)
Earth's invisible shield isn't perfectly round; its magnetic field lines look squished on one side and stretched out on the other due to the constant beating from this solar phenomenon.
What is the solar wind?
If you were to hop into a cosmic time machine and travel all the way back to the exact moment of the Big Bang, this is the estimated number of billions of years (Ga) you would travel into the past.
What is 13.8 billion years? (Accept: 13.8 Ga)
Regular stars can only fuse elements up to iron; elements heavier than iron require the explosive, high-energy death of a massive star, known as this.
What is a supernova?
Ranked from the absolute smallest baby steps to full planetary maturity, it is the correct order of a planet's physical development stages.
What are planetesimal, protoplanet, and planet?
If you are packing a heavy suitcase full of Earth's rock classes, you will have plenty of these minerals, which happen to be the most common mineral group on the planet.
What are silicates?
This is the deepest, heaviest, and most tightly packed layer of our planet, earning the title of the densest layer of Earth.
What is the inner core?
When observing distant galaxies, scientists notice their light wavelengths are stretched out toward the red end of the spectrum, proving this fact about their movement relative to Earth.
What is that they are moving away from us? (Accept: They are receding/expanding away)
Because it contains a rich mix of complex, heavy elements instead of just primitive hydrogen and helium, scientists conclude our solar system must have formed from one of these later-stage cosmic clouds.
What is a second- or third-generation nebula?
Poor Pluto got demoted to a dwarf planet in 2006 because it failed to complete this specific dynamic task required of all true planets.
What is clearing its orbit of debris?
To be an official mineral cardholder, you must be a solid, naturally occurring, and have a tidy, orderly atomic pattern—three rules that automatically disqualify this smooth, unorganized material.
What is glass?
Early in our planet's history, Earth was an incredibly hot, molten mess, which luckily allowed this heavy process to occur, sinking metals to the center and leaving lighter rocks on top.
What is differentiation?
