Question
Read the passage below and answer the question that follows.
Colliding Plates Lab Directions
Materials:
Eurasian Plate model
Indian Plate model
Cup of sand
Metric Rule
Popsicle for smoothing sand
Procedures:
Tape the Eurasian Plate to the desk on all four corners.
Slide the Indian Plate under the Eurasian Plate until the 0 million years reaches the edge of the Eurasian Plate.
Pour all the sand onto the blue square that represents each plate.
Smooth the sand into an even layer. Be careful: the sand should NOT go beyond the edges of the plates.
Use your metric ruler to measure the height of the sand where the two plates meet.
Record the height in your date table under 0 million years.
Slowly slide the Indian Plate toward the Eurasian Plate until the 10 million years line is even with the edge of the Eurasian Plate.
Use your metric ruler to measure the height of the sand where the two plates meet.
Record the height in your date table under the column “10 million years.”
Slowly slide the Indian Plate toward the Eurasian Plate until the 20 million years line is even with the edge of the Eurasian Plate.
Use your metric ruler to measure the height of the sand where the two plates meet.
Record the height in your date table under the column “20 million years.”
If Plate A were more dense than Plate B, how will the results be different from the initial experiment?
Plate A will subduct under Plate B
Plate B will subduct under Plate A
Plate motion will change direction
Plate motion will completely stop

If Plate A were more dense than Plate B, the results would likely indicate that Plate A will subduct under Plate B. In tectonic plates, the denser plate typically moves beneath the less dense plate in a process known as subduction. This would alter the height of the sand where the two plates meet, likely increasing the depth of the area where Plate A is subducting. Therefore, the correct answer is:
**Plate A will subduct under Plate B.**
**Plate A will subduct under Plate B.**
