What does it mean when rocks are arranged in "strata"?
They are arranged in layers!
100
What kind of fossil leaves a hole in sedimentary rock?
Mold Fossil
100
Is this an example of mechanical or chemical weathering? What happened?
Mechanical - frost wedging!
100
What are the three types of rock?
Sedimentary, Metamorphic, Igneous
100
What are 5 senses you use to make an observation?
See, taste, smell, hear, feel
200
Which of these layers is the oldest?
Layer 4 (the bottom)
200
Look at Site 1 - which species went extinct first? How do you know?
Trilobite - because it appears in the oldest layer, and no other layers
200
What is one factor that causes acid rain? And what type of weathering is this?
a) pollution
b) Chemical
200
What is the process (2 things) through which Igneous rock become Sedimentary
Weathering/erosion and pressure
200
Make an observation of the following image:
Ms. Finkel's word goes
300
Based on the fossils in the strata, what happened to this environment through time? (3 steps)
1. Water
2. Lots of options!
3. Forest
300
What are two things that need to happen for an organism to become fossilized? (AFTER it's dead)
1. Buried quickly in ice, amber, or mud
2. Body decomposed
300
What is the difference between weathering and erosion?
Weathering is rocks breaking down, erosion is soil and rocks MOVING
300
Which of these two rocks is probably older, and how do you know?
a)
b)
B, because they are rounder
300
Make an inference based on the following image
Ms. Finkel's word goes
400
What is the Law of Superposition? (make sure to include the word "unless")
Oldest rock layers are on the bottom, newest are on the top, unless there has been a disturbance (like an Earthquake)
400
We found sea shell fossils on top of a mountain! How is this possible?
The environment used to be an ocean (we'll learn more about this next week)
400
Does deforestation lead to MORE erosion or LESS erosion?
Deforestation leads to MORE erosion
400
When this lava cools, what type of rock will it become?
Igneous! When lava cools it becomes igneous rock
400
Make an observation and an inference of an object in the classroom

500
What is it called when rocks are laid down in a new place? (often in layers). "The rocks are _________"
The rocks are DEPOSITED
500
1. What kind of fossil is this?
2. Make one observation (not inference!)
Trace fossil
500
WHY do the Appalachian and Rocky mountains look so different?
Because the Appalachian Mountains are older, and therefore they have eroded more
500
How do rocks get hot enough to melt and become metamorphic rock? (or magma?)
They are pushed closer to the center of the earth, or two big pieces of land collide and create heat
500
Make and observation and an inference of the classroom using a sense other than sight
