These are what bands are called on metamorphic rocks.
What is foliation?
Magma that cools slowly beneath the Earth's surface produces these kinds of rocks. (Be specific.)
True or False: The coast of South Carolina was never underwater.
What is false?
This is the time it takes for 1/2 the amount of a radioactive substance to decay.
What is a half-life?
What is luster?
This forms extrusive igneous rocks.
What is lava?
What is relative dating, index fossils, and absolute dating?
This is a type of fossil that lived a short amount of time and is found in a lot of places. Used to date rock layers and fossils.
What is an index fossil?
Based off superposition, these rock layers are considered the oldest.
What is the bottom layer?
These two things make up a sulfate.
What is sulfur and oxygen?
The relationship between the three types of rocks.
Bonus: Name the three types of rocks.
What is the rock cycle?
Bonus: Igneous, Metamorphic, and Sedimentary.
Extrusive igneous rocks form at this speed, whereas intrusive igneous rocks form at this speed.
1. What is quickly?
2. What is slowly?
This ending is used for minerals that contain oxygen.
What is -ate?
This type of dating gives us a numerical age to a fossil or rock layer.
What is absolute dating?
What is heat and pressure?
What is organic?
This scale is used to measure the hardness of minerals.
What is Moh's?
This kind of graph shows radioactive decay of a substance. (Draw it)
(Should be curved and going down to the right.)
These minerals have copper and aluminum as examples.
What are native elements?
This process creates sedimentary rocks.
What is weathering, erosion, and deposition?
The Earth is this age.
What is 4.6 billion years old?
Rocks are composed of these things.
What are minerals?
The half life of a substance is 10 days. How many grams of a 600g sample will remain after 50 days?
18.75g
These are some characteristics of minerals. Name at least one.
