If there are several stacked rock layers, which layer would you assume to be the oldest?
If there are several stacked rock layers, which layer would you assume to be the oldest?
The bottom layer
Fossils are found in what layer of the Earth?
Fossils are found in what layer of the Earth?
Crust
How could scientists determine the age of a fossil?
How could scientists determine the age of a fossil?
Determine the age of the rock it is found in; Carbon date the rock or fossil
What is an index fossil?
What is an index fossil?
Organism that lived for a short period of time became fossilized in rock; only found in one layer of rock; used to determine the age of the rock
What is our state fossil?
What is our state fossil?
Trilobite
What force can pull magma to the bottom of the mantle?
What force can pull magma to the bottom of the mantle?
gravity
What happens to the density of magma when it is heated?
What happens to the density of magma when it is heated?
The density becomes less
What happens to the magma when it cools down?
What happens to the magma when it cools down?
The magma becomes more dense; the magma sinks
What happens to the density of magma when it is cooled?
What happens to the density of magma when it is cooled?
It becomes more dense
What happens to the magma when it is heated?
What happens to the magma when it is heated?
Becomes less dense; rises to the top

What is the theory of continental drift?
What is the theory of continental drift?
All continents were once together in one large landmass and slowly drifted apart.
What is the name of the plant fossil found on Africa, South America and Antarctica?
What is the name of the plant fossil found on Africa, South America and Antarctica?
Glossopteris
What makes the plates move over time?
What makes the plates move over time?
Convection currents within the Earth
What is this? What does it prove?
What is this? What does it prove?
Glacial grooves are proof of continental drift; grooves create certain patterns and these patterns match on various continents.
Explain why a marine fossil might be found on top of a mountain?
Explain why a marine fossil might be found on top of a mountain?
At one time the land was covered by an ocean.Over millions of years the plates uplifted to form mountains.The fossils on top of the mountain became exposed due to weathering and erosion of rock.
