Ocean Floor
This is found off the shoreline where the edges of the continents are underwater. shallowest part of oceans
What is the continental shelf
What is wave refraction
Underwater volcanic mountains that are higher than 1 km
What is a seamount
A narrow ridge of sand that connects an island to the mainlaind
What is a tombolo
A steep-sided valley, caused by turbidity currents flowing down the continental shelf
What are submarine canyons
How are salts removed from seawater?
marine organisms, wind(carried away in sea spray), formation of evaporites along the shoreline
Long ridges of sand that run parallel to the mainland and serve as a protective barrier to the mainland
What are barrier islands
2 Factors that affect seawater density, therefore deep water currents
What is temperature and salinity
Name one way that salt is added to oceans
volcanic eruptions or weathering and erosion of rock
a rapidly flowing current carrying heavy sediment loads, that can carve submarine canyons
What is turbidity currents
Holes in the seafloor where fluid heated from magma erupts
hydrothermal vents
The deep rift in the middle of mid-ocean ridges
What is the rift valley
What is the most prominent feature on the ocean floor, a long underwater mountain chain, where new seafloor is forming
What is mid-ocean ridge
What is seawater- or higher salinity
The most abundant salt in seawater
What is NaCl (Sodium chloride)
Wave height depends on these three factors
What is fetch, wind duration, and wind speed
