__ The direction that their shells spiral help determine past climatic conditions.
__ This isotope of oxygen can be used to determine past climatic temperature conditions.
__ This is an area where nutrient rich cold water is forced to the surface as a deep current runs into a land mass.
__ The direction moving winds and currents change in the southern hemispheres because of the Coriolis effect.
__ This type of air pressure forms from warm and wet air.
__ These form as a wave reaches a point where depth of the water is less than half the wavelength of the wave.
_L_ The average depth of the oceans.
__ __ Two major factors in producing surface currents.
__ Because of abnormalities in their reproductive environment, even animals capable of this suffer population losses in an El Nino event.
__ This causes winds and currents to turn as they move.
__ This is an area where there is a rapid change in water temperature as you increase depth.
