Based on the information in the table, which layer is most likely the mantle?
Layer C
100
Which type of evidence was NOT used by Alfred Wegener to support his Continental Drift hypothesis
Evidence from human remains.
100
When two oceanic plates collide, this forms a convergent boundary. What land form is created in this process?
All of the above
100
A student is studying a fossil of a fish that was found in the desert. Which statement most likely describes why the fossil was found in the desert?
The desert was covered by water when the fossil formed
100
What keeps the inner core solid even though the temperature is very high?
High Pressure
200
Based on the information in the table, which layer is most likely the inner core?
Layer A
200
What name is given to the theory that the continents slowly move across the Earth's surface?
Continental Drift
200
Weak spots in the crust where magma can flow on the Earth's surface form -
volcanoes
200
What type of fossil evidence supports Wegener’s Continental Drift Theory (Continents moving apart)?
Same dinosaur’s fossils found on different continents
200
Convection currents occur in the mantle. Which statement best describes the motion of convection currents?
Warmer matter rises and is less dense
300
Based on the information in the table, which of the following orders the layers from thickest to thinnest?
Mantle, Outer Core, Inner Core, Crust
300
Which of the following choices most likely would happen when oceanic crust and continental crust collide?
A volcano is formed
300
Which of the following best explains how the Ring of Fire formed?
- Tectonic plates constantly moving.
- Convection currents in the mantle.
- Both A and B.
- Neither A nor B.
Both A and B
300
Corals can only live in warm water. A fossil of a coral was found in the Arctic. How can you explain this?
The Arctic was once a warm place
300
The Earth’s mantle is made up of very hot material that rises to the top of the mantle, cools, then sinks, reheats, and rises again, constantly repeating the cycle. This action, which causes the Earth’s crust to move, is known as -
convection currents
400
What is one difference between layer W and layer X (seen in the diagram)?
Layer W is less dense than layer X.
400
Scientist hypothesized that Earth’s continents were once a single landmass that broke apart. The model below shows South America and Africa breaking apart over the last 200 million years. What evidence best supports this model?
Similar fossils have been found in both continents
400
Use the diagram to answer the question. In which area of Earth are the tectonic plates located?
In the crust and the upper mantle.
400
Two rock samples were taken from the ocean floor. Rock A was taken close to the mid-ocean ridge.
Rock B was taken 500 miles away from the mid-ocean ridge. What statement is most likely true?
Rock B is older than Rock A
400
How does density and temperature change as you move from crust to the core (as you go deeper)?
Both temperature and density increase.
500
Compared to the earth's outer core, the crust is…
less dense and cooler
500
These maps illustrate various stages and locations of the world’s continents. Which of the following is the maps in order showing the continents from Pangaea to today?
Z - X - Y
500
The San Andreas fault is a transform fault. The map below shows a student's approximation of where the fault line crosses the United States. Students were asked to make maps predicting which way land would most likely move over thousands of years.
Which map best predicts the likely movement of land along the fault line over thousands of years?
500
What can fossils reveal about Earth’s past?
Changes in Earth’s climate and surface features over time
500
Compared to the outer core, the inner core is
hotter and more dense
