Continental mountain ranges are formed when two tectonic plates –

• move together forming folds in the land over a long period of time, resulting in a mountain range.

• move apart along a mid-ocean ridge allowing lava to fill ocean basins resulting in a mountain range.

• of different density collide and form trenches.

• collide into each other on a transform boundary.

The picture below shows an erupting volcano. This volcano could have formed and erupted when —

• less dense oceanic crust was forced under denser continental crust, causing the oceanic crust to heat up, melt, and flow upward to relieve pressure.

• denser oceanic crust was forced under less dense continental crust, causing the continental crust to heat up, melt, and flow upward to relieve pressure.

• two equally dense tectonic plates collided and both pushed upward, causing friction that heated up minerals between the two rising plates.

• two equally dense tectonic plates separated and allowed hot minerals from Earth's crust to flow upward and out of the opening that formed between the two plates.

Based on the image above, the boundary between which plates is likely to form an ocean basin?

• North American and Pacific

• South American and African

• Indo-Australian and Pacific

• Eurasian and Indo-Australian

One of the major transform boundaries in the world is on the southwestern margin of the North American plate along the San Andreas fault system. Which type of geologic event is most likely to occur along this boundary?

• Volcano

• Seafloor spreading

• Mountain building

• Earthquake
