2g-Plate tectonics

Which of the following is TRUE about Earth's plates?

• They are separated by oceans.

• They are piled on top of one another within the Earth.

• They are surrounded by melted rock and do not touch each other.

• They fit closely together with each plate touching all the plates that surround it.

The place where two plates come together is known as a _______.

• transform boundary

• convergent boundary

• divergent boundary

• rift valley

What type of boundary is the diagram showing and what can occur at this boundary?

• The diagram shows a convergent boundary, which creates mountains.

• The diagram shows a transform boundary, which creates earthquakes.

• The diagram shows a convergent boundary, which creates a rift valley.

• This diagram shows a transform boundary, which creates a mid-ocean-ridge.

A science teacher shows his students an image of a volcanic mountain range and informs them it was created by the movement of Earth’s tectonic plates. The teacher asks his students to explain how this occurred. Which student’s explanation is BEST?

• An oceanic plate converged with an oceanic plate. Both plates subducted, forcing lava upward towards the surface of the Earth causing a volcanic eruption, which created the mountains.

• A continental plate converged with a continental plate. Neither plate subducted so lava was forced upward towards the surface of the Earth causing a volcanic eruption, which created the mountains.

• An oceanic plate converged with a continental plate. The denser, continental plate sank below the less dense oceanic plate causing magma to rise up through a weak spot in Earth’s crust to create volcanic mountains.

• An oceanic plate converged with a continental plate. The denser, oceanic plate sank below the less dense continental plate causing magma to rise up through a weak spot in Earth’s crust to create volcanic mountains.

Which model BEST represents the tectonic plate motion that is the main cause of new crust and deep rift valleys?

• Model B, because two oceanic plates are pulling apart

• Model C, because two oceanic plates are pulling apart

• Model A, because the plates are converging to create mountains

• Model C, because the plates are converging to create mountains

Which of the following BEST explains what is happening at point A on the model?

• Two tectonic plates are colliding at a convergent boundary, creating a subduction zone which recycles crust.

• Two tectonic plates are pulling apart at a divergent boundary, creating new crust and rift valleys.

• Two tectonic plates are colliding at a transform boundary, creating a subduction zone which recycles crust.

• Two tectonic plates are pulling apart at a convergent boundary, creating new crust and rift valleys.
