Fossils
A preserved remain of a once living organism is a
Fossil
The Idea that Earth has a had a disastrous past is known as
Catastrophism
What are the types of rocks
Igneous, Sedimentary, Metamorphic
This process is how rocks are broken down by wind and water
In rock layers which would be the oldest
The deepest layer
What are the characteristics that make fossils more likely to form
Hard Parts and Buried Quickly
Index Fossils
This rock is made from sediment that has been compressed by weight
Sedimentary Rock
Uplift is the process of
Rocks being brought to the surface by earth processes
An index fossil that lived 350mya is found in a rock layer. What is the age of the rock layer beneath it.
Older than 350mya
A fossil that helps scientist determine the age of a rock layer is a
Index Fossil
Uniformitarianism says this about Earth's past
The Earth has had similar processes for its whole existence.
Metamorphic rock are made by this process
Heat and pressure change the rock
Water moves sediment to new locations what is this called
Deposition
Using the half life of radioactive materials can gives what
If a fossil has similar characteristics to a living organism what do they share in common
They live in similar environments
Layer of the Earth have formed in this way
In even layers (like a cake)
When magma cools slowly underground it forms this type of igneous rock
Coarse grain igneous rocks
Outside of the ground
In a layer of rock there is a column of rock that goes to the highest layer which what is the youngest rock in this example
The column of rock
What is the most common way for fossils to be discovered by scientists
The ground around them is Eroded
Double Points
How do index fossils help scientist find what the environment was like when the organism was alive?
They can compare it to the environment of other, similar looking living things
Which type of rock would be most likely to have fossils form in it.
Sedimentary rocks
What is the process that fuels the whole rock cycle
Plate tectonics or the movement of plates
Fossils of water creatures are found in the desert of Utah. Why are these fossils found here
Utah was once a part of an ocean.
