study of Earth's oceans
a method that determines the distance of an object under water by recording echoes of sound waves
shallow parts of the ocean, includes continental shelf, continental slope and continental rise
a gently sloping, shallow area of the ocean floor that extends outward from the edge of a continent
the steeply inclined section of the continental margin located between the continental rise and the continental shelf
the base of the continental slope which is made of sediment
the part of the ocean floor that is under deep water beyond the continent margin and that is composed of oceanic crust and a thin layer of sediment.
long, narrow, and steep depression formed at a subduction zone
large, flat, almost level area of the deep-ocean basin
volcanic mountains taller than 1 km--form at hot spots
underwater landslide caused by earthquakes
the amount of salt in water
How does temperature of a liquid affect the amount of dissolved solids?
Generally, the higher the temperature of water, the MORE dissolved solids it will have (higher salinity)
How does the temperature of a liquid affect the amount of dissolved gasses?
Generally, the higher the temperature of water, the LESS dissolved gasses it will have.
How does salinity affect density?
The higher the salinity, the higher the density.
Which has more carbon, atmosphere or ocean?
Ocean--it has 60 times more carbon than the atmosphere.
How much of ocean water is dissolved solids?
What are the most abundant elements in ocean water?
chlorine, sodium, magnesium, sulfur, calcium, potassium
What is the most common mineral in the ocean?
Where do sea salts come from?
volcanic eruptions, chemical weathering of rock on land, chemical reactions between sea water and newly formed sea-floor rocks
What effect do river mouths tend to have on the salinity of the surrounding ocean water?
reduces the salinity by adding freshwater
Which has a higher salinity, surface ocean water or deep ocean water?
Surface water--it is hotter and evaporates faster (leaving the salt behind)
long and narrow rift in the oceanic crust caused by a divergent plate boundary
