Earth and Environmental Sciences Fun Quiz: Ocean Floor Features

Nathan, Gio, and Matthew are on a Navy submarine exploring the mysteries of the ocean. They come across a mid-ocean ridge. What is happening along the center of a mid-ocean ridge?

• Tectonic plates are being subducted under the other plates

• Volcanic activity might be seen along the rift valley. Ocean crust is being created.

• Glacial erosion is happening along the ocean floor leaving unsorted, unlayered sediments

• Fossil fuels are being extracted by oil companies

What are the two types of continental margins?

• Passive and active continental margins

• Shallow and deep continental margins

• Northern and Southern continental margins

• Old and new continental margins

How are passive continental margins different from active continental margins?

• Passive continental margins are not tectonically active, while active continental margins are associated with tectonic activity such as earthquakes and volcanic eruptions.

• Passive continental margins are closer to the oceanic ridge, while active continental margins are farther away

• Passive continental margins are more prone to earthquakes and volcanic eruptions, while active continental margins are not

• Passive continental margins are associated with tectonic activity, while active continental margins are not affected by tectonic movements
