What is the layer of the Earth we live on?
Top Layer: Crust
The 3 main categories of rocks are:
Igneous, Sedimentary, Metamorphic
What is a fossil?
A preserved
What forms a delta?
Plate tectonic movement is the reason that this Super continent broke up and our Earth's surface looks like it does today. What is the name of the super continent we studied?
Pangaea
True or False: Oceanic Crust is thinner than Continental Crust.
True
Igneous Rocks are formed by:
Cooling of lava or magma
How are fossils of teeth helpful?
They help us determine what animals could have ate. (Carnivore, omnivore, herbivore)
What type of Plate Boundary create most mountains and volcanoes?
Convergent Boundaries. (C=CRASH together)
How many different types of plate boundaries did we study this quarter of the school year?
What is the only liquid layer of the layers of the Earth?
Sedimentary Rocks are formed by:
Weathered sediments being pressed and cemented together.
What are microfossils good for?
To help us determine the type of environment that could have been.
The rapid downslide of rocks and sediments and mud is called:
Landslide
What are the names of the three different types of plate boundaries?
Convergent, Divergent, Transform
What are two facts about the Mantle?
Thickest Layer
Divided in two parts: Top part moves Plates of the crust.
Molten Rock
Made of Magma
Metamorphic Rocks are formed by:
Heat and pressure, form from other types of rocks
Sedimentary Rocks
Hydro= Water
Geo=?
Land/Ground
Which layer of the Earth has the biggest "dog pile" affect?
The inner core has the most pressure!
Why are the arrows in the rock cycle diagram important?
They show that rocks can move anyway on the rock cycle. Rocks can become a different type of rock.
When digging in a core sample. Where would you find the oldest fossils for a fossil record?
At the bottom layer of your core sample.
Destructive means to break down so: Weathering, erosion, landslide, avalanche.
What is the difference between erosion and deposition?
Erosion is the movement of sediment
Deposition is where the sediment drop/lands/collects.
