Vocabulary:
Mid-Ocean Ridge: a long, seismically active submarine ridge system situated in the middle of an ocean basin and marking the site of the upwelling of magma associated with seafloor spreading.
Seamount: a submarine mountain.
Volcanic Island: The term can be used to distinguish such islands from low islands, whose origin is due to sedimentation or uplifting of coral reefs.
Deep Ocean Trench: Steep-sided canyons.
Abyssal Plain: An abyssal plain is an underwater plain on the deep ocean floor, usually found at depths between 3000 and 6000 m. Lying generally between the foot of a continental rise and a mid-ocean ridge, abyssal plains cover more than 50% of the Earth’s surface.
Continental Slope: the slope between the outer edge of the continental shelf and the deep ocean floor.
Continental Shelf: the area of seabed around a large landmass where the sea is relatively shallow compared with the open ocean.
Questions and Answers:
1.) Why doesn't Earth get larger when new rock is added to
the ocean floor at the mid-ocean ridge?Because is getting renew every time by the ocean floor process.
2.) What factors make it difficult to explore the ocean
floor? The ocean floor is difficult for 3 reasons . The deep ocean is totally dark, the water is very cold and finally the water pressure is very high.
