What is it called when a wave crests and bends as it reaches shallow water?
What is wave refraction?
100
This type of current flows parallel to the shore.
What is a longshore current?
100
What is the ridge of sand that connects an island to the mainland called?
What is tombolo?
200
What type of volcano is basalt with a flat submerged top?
What is a guyot?
200
What is the smooth part of the ocean floor at 5-6 Km below sea level?
What is abyssal plain?
200
What is the rapid flowing current along the bottom of the ocean?
What is a turbidity current?
200
This forms in front of the beach where the current has built up sediment.
What is the a longhshore bar?
200
This is a narrow bank of sand that projects into the water from a bend in the coastline.
What is a spit?
300
What percent of the earths surface is ocean floor?
What is 60%?
300
Where does the sediment come from in the ocean?
What is a continent?
300
A current can affect this structure which protects property from storm waves and reflects the energy of the waves.
What is a seawall?
300
These are ridges seperated from the mainland and are made of sediment deposited by longshore currents.
What are barrier islands?
300
Were Earth's seas higher or lower than they were 10,000 years ago?
What is lower?
400
These can be black or white and are part of submerged basalt volcanoes.
What are hyrdrothermal vents?
400
What is the element that makes the reddish color in deep sea sediment?
What is Manganese?
400
This is built perpendicular to the shore to protect against waves but can cause erosion further down the beach from its position.
What is a Groin?
400
This is the shallowest part of the continental margin reaching seaward from shore.
What is a continental shelf?
500
What is deep sea sediment from a land source called?
What is Terrigenous sediment?
500
These are deep sea mud accumulations from once living organizims?
What is oozes?
500
If a wave cuts into a headland and that headland is eroded, what is formed?
What is a wave cut platform?
500
These are formed by turbidity currents deep in the ocean.
What are submarine canyons?
500
This is a gently slope at the base of a continental slope that is formed by sediments deposited by turbidity currents.
What is continental rise?
