Scientific Method
Name the steps of the scientific method
1. Observe problem
2. Research
3. Hypothesis
4. Experiment
5. Collect Data
6. Conclusion
Name the layers of the earth starting from the outside of the earth
1.crust
2. mantle
3. Outer Core
4. Inner Core
Name the 3 types of rock
igneous, sedimentary, metamorphic
What are the 3 boundaries
1. Divergent
2. Convergent
3. Transfrom
What is weathering?
Breaks down the rock
What is the independent variable
What the scientists changes in the experiment
Name the layers from the most dense to least dense
1. Inner Core
2. Outer Core
3. Mantle
4. Crust
How are each rock formed?
igneous - cooled magma/lava
sedimentary - weathering, erosion, deposition, compactioin
Metamorphic - heat and pressure
What is it called when a plate slides under another plate
Subduction
What is the best environment for chemical weathering?
Hot and humid (wet)
What is it called when a variable stays the same through out the whole experiment
Constant
What evidence helped us discover the inside of the earth?
seismic waves
How can we go from an igneous rock to a sedimentary rock?
rock is weathered, moved (erosion), placed or dropped in new location (deposition), compacted.
Name the features each plate boundary makes
1. Divergent:
O-O:sea-floor spreading
C-C :Rift Valley
2. Transform: Earthquakes
3. Convergent:
C-C : Mountains
O-O: Underwater Volcano
O-C : Volcano
What is the difference between erosion and deposition
Erosion - moves the sediment
Deposition - drops the sediment in new location
Why must we research?
To help us get an educated hypothesis and to learn the most new and recent information
Name the 3 types of seismic waves and how they move
1. S- waves (come after P waves, move through only solid)
2. P - waves (fastest, move through solid and liquids)
3. Surface (move the ground)
What are the 5 ways we identify a mineral?
1. Luster
2. Streak test
3. Mohs Scale
4. Density
5. breakage
Name the 3 types of stress and what boundary movement causes them
Shearing- Transform
Compression- Convergent
Tension- Divergence
What causes rocks and fossils to move up to the surface?
faults and earthquakes
Create an experiment naming the independent, dependent and constant variables.
answers will vary
Explain how the seismic waves helped us discover the layers of the earth
What is the best way to test the hardness of a mineral?
1. Rubbing on other minerals
2. doing streak test
What causes the plates to move? Explain
Convection Currents
Explain the cross cutting law
the rock that cuts through another rock is always younger
