Seafloor spreading

The video explains the formation of new rock at mid-ocean ridges and how this process influences tectonic plates, contributing to continental drift by pushing the plates apart.

What geological feature is associated with the formation of new rock in the ocean?

• Volcanic islands

• Mid-ocean ridges

• Ocean trenches

• Coral reefs

What are tectonic plates primarily composed of?

• Ice

• Rock

• Sand

• Water

How does the formation of new rock affect tectonic plates?

• It pushes them apart

• It causes them to sink

• It pulls them together

• It makes them rotate

What process is driven by the movement of tectonic plates?

• Sedimentation

• Erosion

• Continental drift

• Weathering

Which of the following is NOT a result of tectonic plate movement?

• Volcanic activity

• Tidal waves

• Mountain formation

• Earthquakes
