These kinds of rocks are formed when magma cools.
Igneous
Which type of fossil is actual parts of the plant or animal?
True Form
True or False: The continents have stayed in the same place over time.
False
In what layer would the oldest rocks be found? Where would the youngest rocks be found?
Oldest- Layer D
Youngest- Layer A
The boundary that creates faults.
Transform
The fossils on the east coast of South America match the fossils on the west coast of Africa. Fossils are found on both continents/both locations even though they are separated by an ocean.
Which can occur in the rock cycle?
A. Sedimentary rock is heated and squeezed to become metamorphic.
B. Metamorphic rock melts to form sedimentary rock.
C. Sedimentary rock is eroded to form igneous rock.
D. Igneous rock is eroded to form metamorphic rock.
A. Sedimentary rock is heated and squeezed to become metamorphic.
Which type of fossil is a fossilized footprint?
Trace Fossil
The name of the supercontinent from 300 million years ago.
Pangea
Which type of rock would these fossils be in? Explain your reasoning.
Sedimentary, it has fossils or it is made of layers.
The boundary that creates mid-ocean ridges.
Divergent
What process causes metamorphic rocks to form?
Heat, pressure, and time
Which type of fossil is the space left after an organism decays?
Mold Fossil
What causes one plate to sink under another?
It's density
The boundary that creates continental mountains.
Convergent
What is the difference between weathering, erosion, and deposition?
Weathering is the breaking of rocks.
Erosion is the moving of rocks.
Deposition is the layering/dropping of rocks.
How can a metamorphic rock become a sedimentary rock?
By weathering/ erosion AND cementation/ compaction
Which fossil is a 3-D image left after a mold fossil is filled in?
Cast Fossil
The cycle of heating, rising, cooling, and sinking of magma that causes the plates to move.
Convection Currents
What can fossils of fish bones in the desert tell us about the area in the past?
That it was once underwater.
Which process caused the creation of the Grand Canyon?
A. Plate Movement
B. Weathering and Erosion
C. Deposition
D. Sun
B. Weathering and Erosion
Where in the rock cycle can you start for a rock to become any other type of rock?
Anywhere
What type of fossil is an insect trapped in amber?
True Form Fossil
What clues did scientists have that the continents were once connected? (Give at least 2 to get full credit)
Fossils of plants and animals and rock formations on different continents. Continents' coastlines look like they fit together.
Has the environment in this picture changed over time? Explain with details.
Yes, the environment has changed. Layer D has shells which tells us it is a water environment. Layer C has a dinosaur which tells us it is a land environment. Layers A and B have fish and shells which tell us that it has gone back to a water environment. Now it is a desert because of the cactus growing.
If there is a convergent boundary on one side of a plate, what type of boundary would most likely be on the other side?
Divergent
