Scientists can predict exactly when a volcanic eruption will occur.
True
False
Why is it beneficial to be able to predict when and where natural hazards will occur?
Communities can be notified to evacuate
So that we can stop them from happening again
So that scientists know where to go in order to study them
So that we can harness their power for renewable energy
A mountain area in the Pacific Northwest has many landslides. What most likely causes these rocks and soils to erode?
tree roots
gravity and rainfall
glaciers
frequent volcanic eruptions
What can scientists measure to help predict when a volcano might erupt?
temperatures of lava flows
lengths of nearby fault lines
small earthquakes and gases in the air near the volcano
increases in severe weather
Why do storms spin in different directions?
because they are falling
because of the eye
because of cold ocean temperatures
because of the Earth's rotation on its axis
What is it called when geologists use the position of rocks and their fossil contents to determine their age?
Absolute dating
Relative dating
Radioactive isotopes
Metamorphism
Which layer is the oldest in this sequence of rocks?
H
M
R
I
Which geological principle lets you know that layer H is younger than layer M?
The Principle of Superposition
The Principle of Intrusive Igneous/ Cross-Cutting Relationships
The Principle of Original Horizontality
The Principle of Lateral Continuity
Which Principle tells you that layer I is the oldest?
The Principle of Superposition
The Principle of Cross-Cutting Relationships
The Principle of Lateral Continuity
The Principle of Fossil Succession
The disappearance of a species.
Evolution
Extinction
Migration
Mutation
If we want to figure out the age of layers from two different locations what would be the best way to do so?
We can compare the fossils found in the layers of one location to the fossils in the other location
We can use the law of superposition to figure out the rate of layer formation
Radioactive dating to compare the age of the rocks in the layers
Compare the number of layers in each location
Why may fossil of the same organism be found on different continents?
Because the continents were once together
Similar fossils should not be found on different continents
Because fossils change over time
Because of the Evolution of the Earth
