Document Summary

3. 5% of seawater is composed of chemicals. Ocean surface currents- are driven by wind, heating, cooling, density gradients, and the coriolis. Density gradients- layers in the ocean with varying amounts of densities. Deep zone = 80% of ocean water. Density is determined by salinity and temperature. The lower layers are the most dense and the coldest. Heat capacity- a measure of the heat energy required to increase temperature by a given amount. Water has a high heat capacity, meaning it takes a lot of heat to move it. Oceanic process: wind blows from the north along the coastline, coriolis effect caused surface water to move away from the coast. That piece of shit changed the slide after 30 seconds there still like 3 more steps. El nino- years when warm water is blown into the pacific ocean. Ex: lots of rain in peru while there is a drought in indonesia. El nina is a year with normal conditions.
