Plate Tectonics/ Earth Science

How is oceanic crust that is further away from a rift valley different from oceanic crust at the center of a rift valley?

• Crust further away from a rift valley is younger than crust at the center

• Crust further away from a rift valley is older than crust at the center

• Crust further away from a rift valley is less dense than crust at the center

• Crust further away from a rift valley is the same as crust at the center

When magnetic minerals in basalt point north what does this record?

• This records a time where polarity is reversed

• This records a time when the continents are not moving

• This records a time when polarity is normal

• This records nothing because magnetic minerals always point north

Which statement correctly describes how 2 tectonic plates sliding past eachother at a transform plate boundary change Earth's surface?

• They cause earthquakes and move rocks down

• They cause volcanism and move rocks up

• They cause mountain building and move rocks up

• They cause earthquakes and move rocks laterally

An earthquake is caused by plate interactions. What makes an earthquake happen?

• 2 tectonic plates collide and rocks merge together

• 2 tectonic plates slide past one another and grind against eachother

• 2 tectonic plates pull apart and rocks dissolve

• A tectonic plate moves over a hot spot and melts

Evaluate the student's model. What would you change?

• Instead of pushing the crackers, slide the crackers past one another

• Instead of pushing the crackers, pull the crackers apart

• Place the crackers far apart, then quickly push them together

• Do not change the model
