layers of the earth
DOUBLE JEOPARDY
Which layer of the earth is the most dense?
Inner Core
TRIPLE JEOPARDY
What is the plate boundary where two plates collide? (move towards each other)
Convergent
How old is earth?
4.5 billion years old
Which force is holding you to the earth right now?
gravity
When doing a punnett square, where do the parent genotypes go?
Top and side of square
Which layer of the Earth is a liquid?
Outer core
What does glacial mass movement cause?
Glaciers move across land causing glacial striations (stripes of weathered rock)
DOUBLE JEOPARDY
What came first: fish or land animals?
Fish
You are accelerating at a rate of 8 m/s2 to the right. Are the forces balanced or unbalanced?
Unbalanced
List an example of a phenotype
Green eyes
Which layer of the earth is the LARGEST?
Mantle
How was the grand canyon formed?
What is relative dating? (law of superposition)
Oldest rocks on the bottom, youngest rocks on the top
You are moving at a constant speed to the left.
Are the forces balanced or unbalanced?Balanced
What is a codominant trait?
Two traits that are both dominant. They will both show when expressed
Example: roan cow (red and white)
DOUBLE JEOPARDY
Put these in order from what happens first to what happens last:
seismic waves, convection currents, earthquake, plate movement
1. convection currents
2. plate movement
3. earthquake
4. seismic waves
Name two landforms that form at seafloor spreading sites
Rift valley and midocean ridge
What two things make a fossil an index fossil?
only in one layer (across) and widespread (in every column)
DOUBLE JEOPARDY
What is the difference between a contact and non contact force? Name one example of each.
Contact = touching (friction, applied, normal)
Noncontact = nontouching (gravity, electrostatic, magnetic)
Two parents: BB x BB. What are the genotypic outcomes?
100% BB offspring
How do seismic waves prove that the earth has different layers?
seismic waves refract when there is a change in density or temperature proving that there is a change in layer
Describe the plate boundary and type of crust involved in a subduction zone.
Convergent boundary, oceanic crust moves below continental crust
Name two ways the geologic record show changes in Earth's surface over time
- shows weathering/erosion of rock
- shows plant/animal fossils that were around at a time
-shows climate of the time
- age of certain fossils based on uniformitarianism
What is the net force?
300N -->
200N <--
100N up
100N down
100N-->
