What is relative dating?
Stating whether something is older or younger than something else
200
What are the 2 types of observations/data and what is the difference between the 2?
Qualitative - Descriptions

200
What is mass?
How much matter something has

What information can a Geologic Time Scale provide geologists and archaeologists?
1. Tell us how old the Earth is known to be
2. Tells us the relative age of fossils and rocks compared to others
3. Can show the order of events, eras, periods throughout Earth's history
4. Can help us compare ages and dates of rocks and fossils with others
300
What is the dependent variable?
What you are measuring in an experiment
300
What is the formula to find density?
Density = Mass / Volume
300
What base unit would you use to measure volume?
Liters
300
How is a fossil formed?
An organism dies and its remains are preserved, often by being covered in layers of sediment.

What is the 4th step in the Scientific Method?
Experiment
400
You are finding the density of an oddly shaped rock. The rock has a mass of 10 grams. The rock is placed in a graduated cylinder with 25 mL of water. After the rock is placed in the graduated cylinder, the water line rises from 25 mL to 30 mL. What is the density of the rock?
Mass = 10 grams
Volume = 30 mL - 25 mL = 5 mL
10 grams / 5 mL
Density = 2 g/mL
400
What base metric unit would you use to measure mass?
Grams
400
What is a fossil cast and how is it formed?
A fossil that is formed when an organism dies leaving an imprint which becomes hardened and may be filled in.
400
What is radiometric dating, and how does it work?
Radiometric dating is a method of absolute dating that involves measuring radioactive particles in rocks.
500
What are the 3 things that make a good scientific question??
1. Clear and specific
2. Measurable
3. Testable
500
What is the definition of density?
How tightly packed the particles are in a substance
500
How many grams is 32 kilograms?
32,000 grams

What fossil formation is represented by the following description?
Organism undergoes slow, complete dissolving and its original mineral is replaced with another mineral.
Replacement

Explain the Law of Superposition
The Law of Superposition states that rock layers deeper down are older, and any rock layers that form above it are younger.
