Document Summary
> colder it gets, the saltier and denser the water is. > places near oceans and lakes have less extreme temperatures during summer and winter. Upwelling = upward flow of cold, deep water where winds blow away from, or parallel to, coastlines. Downwelling = oxygen-rich water sinks where surface currents come together. > cold water sinks and pushes the water to the south. > are both affected by the climate change. > what will happen if the thermohaline circulation stops. Normal conditions-> upwelling will bring cold winds to south america (la nina -hot) Now-> trade winds fail failure fishing-> there"s no upwelling to push fish up the the surface. > drought -> because rains in the middle of the ocean. Benthos-> sitters: coral reefs shallow subtropical and tropical waters. ~25% of all marine species economically important losses of at least 40% worldwide.
