False!
100
What is Mr. Gonzales' favorite color(s)?
Green or earth tones
100
What does inclusion mean?
A piece of an older rock that becomes a part of a new rock.
100
Geologists organized the geologic time scale based on...
A) rock record

D
200
True or False:
the principle of uniformitarianism states that sedimentary rocks are deposited in horizontal layers.
True:
The idea is that Earth has always changed in uniform ways and that the present is the key to the past.
200
When part of the rock record is destroyed, the erosional gap that forms is a(n) ____.
An unconformity!
200
METRIC SYSTEM:
Convert 80,000 grams to kg
1 kg = 1000 g
80,000 grams = 80 kg
80,000/1000 * 1kg = 80 kg
200
What is the vocab word for this definition:
the principle that if one geologic feature cuts across another feature, the feature that it cuts across is older.
Cross-cutting relationships
200
Refer to the figure to answer the following question:
Layer J is ____________ Layer N.
A) older than
B) the same age as
C) younger than
C) younger than
300
~~DOUBLE POINTS~~
The principle of superposition can be used to determine...
The relative age of rock layers.
300
Rock layers are correlated if they both contain the same...
Fossils
300
What is the difference between a science law and a theory?
A theory is a well-supported explanation of observations. A scientific law is a statement that summarizes the relationship between variables.
300
What is a key bed?
A rock or sediment layer with distinctive characteristics that make it easily identifiable in correlation.
300
Refer to the figure below to answer the following question:
The erosion of Layers L, M, and N that occurred ____________ Event P.
original horizontality
400
How do scientists know how old the Earth is?
Acceptable answer:
using relative age dating techniques or correlation of rock layer/ fossils
400
~~DOUBLE POINTS~~
The gap in the rock record that occurs between folded or uplifted rock layers and a sedimentary rock layer on top of them is called a(n) ...
Angular Unconformity
400
~~DOUBLE POINTS~~
Give at least 1 Nature of Science!
Acceptable:
1. Different Ways to Study: Scientists use many ways to study things like experiments and observations.
2. Facts from Experiments: What scientists know is based on real-world evidence they gather by doing tests and experiments.
3. Changing What We Know: Scientists can change their ideas if they find new proof that something is different from what they thought before.
4. Explaining How Things Work: Scientists have explanations like stories or rules to tell us how things in nature happen, like why a ball falls down when dropped.
5. Learning through Science: Science is a special way of learning about the world by asking questions, trying things out, and learning from what we see.
6. Nature Follows Rules: Scientists believe that nature works in an organized way, and there are rules that things follow.
7. People Do Science: Real people, like you and me, are the ones who do science by asking questions, exploring, and finding out new things.
8. Understanding Our World: Science helps us find answers to questions about things we can see and touch in the world around us.

What is the vocab word for this definition:
The principle that most rock-forming materials are deposited in horizontal layers.
Original horizontality

~~DOUBLE POINTS~~
Identify and describe three different types of unconformities.
Three types of unconformities are angular unconformities, disconformities, and nonconformities.

What vocab word is this definition:
A method used by geologists to fill in the missing gaps in an area’s rock record by matching rocks and fossils from separate locations.
Correlation
500
Describe how geologists use index fossils.
Geologists use index fossils to correlate rock layers over large geographic areas or to date a particular rock layer.
