Fossils
Trace Fossil
What is the difference between a mineral and a rock.
Minerals are made up of the same elements each time and they have a set chemical structure. Rocks can be made of all types of sediment and bits of minerals. Rocks do not have a set chemical and physical structure.
What is magma?
Melted rock
What is Pangea?
Why are some minerals more expensive than others?
It depends on how rare they are
An imprint of an organism is an example of what type of fossil.
Mold fossil
Minerals that have been cut and polished.
What is sediment?
Broken down bits of rock, sand, dirt, and shells
Why do plate tectonics move?
Magma moving due to convection currents
What is de-extinction?
Trying to bring an animal back from extinction
What is a cast fossil?
When an imprint of an organism is filled with sediment and it creates a 3D model of the organism.
What are three examples of minerals:
Gold, silver, diamonds, quartz, rubies, etc.
What are the 3 types of rocks?
Sedimentary, Metamorphic, and Igneous
What are 2 things that occur at transform boundaries.
Earthquakes and tsunamis
What is the most crucial thing to bring an animal back from the dead?
DNA
What are the four types of fossils?
Cast fossil, mold fossil, trace fossil, and true form fossil.
What are 2 ways we classify minerals.
Mohs hardness scale, streak test, luster, tenacity, cleavage/fracture, color, or specific gravity
How are sedimentary rocks formed?
When sediment (bits of rock and sand) are pressed together to form a rock
What are 2 things that can occur at a divergent boundary?
Seafloor spreading, underwater mountains and volcanoes, volcanic eruptions, new land, separation of islands and continents by water
What were the 2 separate continents called when Pangea first broke apart.
What is the Law of Superposition?
That in layered rocks, the oldest rocks are on the bottom.
What is the Mohs hardness test?
Tells us how hard different minerals are. You do it by scratching the mineral.
How are metamorphic rocks formed?
When an existing rock undergoes extreme heat and pressure.
What are 2 things that can occur at convergent boundaries?
Mountains, volcanoes, ocean trenches
What are convection currents?
Hot liquids and gases rise and cold liquids and gases sink
