What is 3.5%
Temperature for most nutrients
What is cooler waters, typically between 0°C and 5°C
Horizontal movements of water near the ocean's surface
What is surface currents
Structures built along the coast to protect against erosion
What is Seawalls
The 5 major oceans
What is Pacific, Atlantic, Indian, Artic, and Southern.
Sources of minerals in the ocean
What is weathering, volcanic activity, hydrothermal vents
Caused by the difference in temperature between the warm surface waters and the colder deep waters
What is the cause of Thermocline
large-scale circular ocean currents
What is Gyres
Beaches, Sandbars, Spits, and Barrier Islands
What is depositional features
Properties of ocean water
What is a mixture of dissolved gasses and solids in pure water
Processes that decrease salinity
What is precipitation, river runoff, melting of icebergs and glaciers.
Colder water and saltier water
What is factors affecting density of ocean water
Currents formed in the low latitudes (near the equator) generally move..
What is Westward
Cliffs, sea caves, Sea Stacks, Marine Terraces
What are Erosional Features
Ocean's role in the water cycle
What is Evaporation, Precipitation, Runoff, and Infiltration
Processes that increase salinity
What is evaporation and formation of sea ice
Caused by changes in temperature and salinity.
What is the pycnocline
Deflection of currents
What is the Coriolis effect
The lowest point of a wave
What are Troughs
Smallest and shallowest ocean
What is the Artic
Salinity changes due to various factors
What is increase in freshwater, freezing water in polar regions, unusually warm temps, and too little rain.
Most abundant gasses in Ocean water
What is Carbon dioxide, oxygen, and nitrogen
A large-scale circulation pattern in the ocean that involves both surface currents and deep ocean currents.
What is the global conveyor belt
Narrow, finger-like extensions of land that form at the mouths of bays or estuaries
