Describe the Intertropical Convergence Zone
Narrow zone near equator where Northern and Southern air masses converge, produce low pressure atmosphere and rain.
Lines joining points of equal pressure
Isobars
A break in the geologic record created when rock layers are eroded or when sediment is not deposited for a long period of time.
Unconfirmity
Winds of SouthEast Asia and Indian Ocean change directions seasonally from NorthEast from November to March. SouthWest from April to October accompanied by heavy rain.
Monsoon
Where is the world are monsoons the most intense
Indian Ocean
Describe the jet stream and how it affects air travel in the USA
Fast moving rivers of air traveling from West to East, saves time and fuel if going eastward

Co-invented S.C.U.B.A. in 1943 Championed the idea that humanity should protect ocean life.
Cone shaped mountain peaks
Seamounts
Ring-shapped coral islands formed on sinking volcanoes
Atoll
Which ocean has the most deepest sea trench
Mariana Trench
Which ocean has the most longest-sea trench
Peru-Chilie Trench
Why is ice less dense than water?
The hydrogen bonds pack the molecules less compact in the ice

Sargasso Sea
Ocean currents in Atlantic driven by warm surface currents and deep water
Gulf Stream Current
Explain the cause of the current flowing through the Strait of Gibraltar
Exchange of water due to evaporation between Atlantic Ocean and Mediterranean Sea
Why is upwelling important?
It brings greater concentrations of dissolved nutrients, such as nitrates and phosphates, to the ocean surface
What drives deep ocean currents
Differences in water density- temperature and Salinity
What happens to the salt when seawater freezes
It stays in the liquid water, it doesn't go into the ice
