The ocean is constantly in motion, moving water from place to place via currents. Mean level of the ocean surface. tropical storms or hurricanes cause them. Water Density. Currents are predictable and are affected by the Coriolis Effect, which is due to Earth's rotation. coriolis effect. Warm water at the equator rises because it's less dense and moves toward the poles. Functional cookies help to perform certain functionalities like sharing the content of the website on social media platforms, collect feedbacks, and other third-party features. Surface currents occur at the surface of the ocean and are caused by global winds; the Gulf Stream is an example. This cookie is set by GDPR Cookie Consent plugin. What are the factors affecting the density of seawater? What are the two main factors that affect deep ocean currents? Surface water flows in to replace the sinking water, which in turn becomes cold and salty enough to sink. These cookies will be stored in your browser only with your consent. Deep currents form because of density differences. What is a surface current that cause surface currents to occur quizlet? If the drag resistance on the car due to the wind is FD = (10v) N, where v is the velocity in continental deflection. The zone of rapid change from warm water to cold water with increasing depth in the ocean. Ans. int temp; Tides create a current in the oceans, which are strongest near the shore, and in bays and estuaries along the coast. ```. Surface currents are extremely important because they distribute heat around the planet and are a major factor influencing climate around the globe. Surface currents are created by three things: global wind patterns, the rotation of the Earth, and the shape of the ocean basins.

Warm ocean currents increases the temperature of the near by coastal areas while cold ocean currents bring down the temperature. As the warm water comes in, colder, denser water sinks and begins moving southeventually flowing along the bottom of the ocean all the way to Antarctica. Compare and contrast western boundary currents to eastern boundary currents.
