Plate Boundaries & Earthquakes

How does plate tectonics cause ocean basin formation?

• New crust forms due to seafloor spreading at convergent boundaries.

• New crust forms due to seafloor spreading at divergent boundaries.

• Oceanic trenches form at transform boundaries.

• Oceanic trenches form at divergent boundaries.

Look at the image with two empty boxes for labels. How can you correctly label the boundary type in each box?

• Both labels should say transform boundary.

• Both labels should say divergent boundary.

• From left to right, the labels should say convergent boundary, then transform boundary.

• From left to right, the labels should say divergent boundary, then convergent boundary.

Describe how tectonic plates cause ocean basins to form. Include information about the type of plate boundary, the seafloor feature(s) formed, and convection currents in the mantle.

• Tectonic plates cause ocean basins to form at divergent boundaries, where seafloor spreading creates mid-ocean ridges, driven by convection currents in the mantle.

• Tectonic plates cause ocean basins to form at convergent boundaries, where subduction creates deep ocean trenches, driven by convection currents in the mantle.

• Tectonic plates cause ocean basins to form at transform boundaries, where lateral sliding creates fault lines, driven by convection currents in the mantle.

• Tectonic plates cause ocean basins to form at passive margins, where sediment accumulation creates continental shelves, driven by convection currents in the mantle.

Satellite technology has allowed scientists to detect vertical movements of rock on Earth. Over a 4-year period, satellites measured locations in the central portion of the Alps Mountains and determined there was an increase of approximately +2.5 mm per year. The Alps are located on the Eurasian plate and are labeled on the map.

Describe the geologic process that is most likely responsible for the Alps continuing to grow taller. Refer to specific plates when describing movement.

Which of the following is a correct statement about how tectonic plates cause earthquakes?

• The movement of tectonic plates releases seismic waves that radiate from the focus of an earthquake.

• The movement of tectonic plates creates tsunamis, which can cause earthquakes.

• Seismic waves constantly flow through tectonic plates. When the waves reach a plate boundary, they cause an earthquake.

• Earthquakes are not caused by tectonic plates.
