What are the four interactions?
Commercialism, parasitism, competition, and symbiosis.
What are the layers of Earth inner to outer?
Inner core, Outer core, mantle, Crust
What is the age of Earth?
4.6 billion years old.
What are the three types of rocks
Igneous, Metamorphic, Sedimentary rocks
Is Earth expanding?
No.
What is a symbiotic relation ship?
Where one organism is benefitted and one is unharmed.
WHat layers is most dense to least dense?
The more outer it is, the more dense it is.
What is the law of superposition?
Stacking two rocks so they eventually coincide.
what is the difference between intrusive and extrusive igneous rocks?
The two main categories of igneous rocks are extrusive and intrusive. Extrusive rocks are formed on the surface of the Earth from lava, which is magma that has emerged from underground. Intrusive rocks are formed from magma that cools and solidifies within the crust of the planet.
What are the three clues for land evidence?
Ancient fossils, Rocks, and Mountain Ranges.
What are the three types of animals?
Carnivore, Omnivore, herbivore.
What are the temparatures in order from least to greatest.
Inner core the hottest, crust the coldest.
What is the difference between an index fossil and a regular fossil?
Index fossils are fossils that are widespread but only existed for a short period of time, while regular fossils take a while to be formed under Earth.
What energies/forces drive the rock cycle?
Earth's internal heat.
What is the name of the supercontinent?
Pangea.
what are the 5 levels for the organization of the environment?
Organism → Population → Community → Ecosystem → Biosphere
What are fossils and what are the types of them?
Trace fossils, body fossils.
Fossils are ancient organisms preserved deep inside the Earth.
What is a geologic time scale?
Earth scientists date certain historical events and record it on a time scale overtime.
How do you find the age of a rock?
Radiometric dating.
Who came up with the theory of seafloor spreading?
Harry Hess.
What is the order of a food chain?
Producer, Primary consumers, secondary consumers, tertiary consumers.
What are convection currents
transfer heat from one place to another by mass motion of a fluid such as water, air or molten rock.
What is period, era, eon, and epoch from largest to smallest?
eon = The largest unit of time. era = A unit of time shorter than an eon but longer than a period. period = A unit of time shorter than an era but longer than epoch. epoch = A unit of time shorter than a period but longer than an age.
How do rocks get their shape?
Rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming—that are part of the rock cycle.
What happens to magnetic poles.
They gradually shift.
