It extends all the way up the eastern coast of the United States and Canada. cin >> Winds and currents flow faster at the equator than at the poles. Knowing the sea surface temperature can give scientists information about what is happening in and around the ocean. Warm water at the equator rises because it's less dense and moves toward the poles. Oceanic currents are driven by three main factors: Surface currents are controlled by three factors: global winds, the Coriolis effect, and continental deflections. How can wind-driven horizontal movement of water induce vertical movement in surface water? Another major factor in the creation of currents is water density, caused by the amount of salt in a body of water, and its temperature. What are the causes of ocean currents Class 11?

Estimate the position and size of the final image formed by a system of elements consisting of an object $2.0 \mathrm{~cm}$ high located at $x=0 \mathrm{~m}$, a converging lens with focal length $5.0 \cdot 10^1 \mathrm{~cm}$ located at $x=3.0 \cdot 10^1 \mathrm{~cm}$ and a plane mirror located at $x=7.0 \cdot 10^1 \mathrm{~cm}$. Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earths surface. The infant is very sleepy and does not respond to painful stimuli. Currents may also be caused by density differences in water masses due to temperature (thermo) and salinity (haline) variations via a process known as thermohaline circulation.

Gravity tends to pull items towards the surface of the earth. In fact, England is about the same distance from the equator as cold regions of Canada, yet England enjoys a much warmer climate. What 3 factors affect major ocean surface currents? There are four factors affecting the origin and flow of Ocean Currents i.e. 2 What are five factors that affect ocean current flow? They make the coastal climate cooler and dryer than the inland climate. it brings cold deep nutrient laden water to the surface where it can take in sunlight and conduct photosynthesis. This strong current of warm water influences the climate of the east coast of Florida, keeping temperatures there warmer in the winter and cooler in Differences in water density, resulting from the variability of water temperature (thermo) and salinity (haline), also cause ocean currents. What causes ocean surface currents quizlet? Currents are predictable and are affected by the Coriolis Effect, which is due to Earth's rotation. Complete Answer:The ocean water is constantly in motion and the motions are north-south, east-west, alongshore, and vertically.

This "starts" theglobal conveyer belt, a connected system of deep and surface currents that circulate around the globe on a 1000 year time span. The Gulf Stream is an ocean current that carries warm water up the eastern coast of the United states and Canada and on to western Europe. affected by 3 factors; continental deflections, the coriolis effect, and global winds. they are so dangerous because they can flood costal residences without much warning. Deep ocean currents (also known as Thermohaline Circulation) are caused by: The sinking and transport of large masses of cool water gives rise to the thermohaline circulation, which is driven by density gradients due to variations in temperature and salinity. Let us know. These currents support the growth of phytoplankton and seaweed which provide the energy base for consumers higher in the food chain, including fish, marine mammals, and humans. They are driven mainly by winds. Ocean currents are streams of water flowing constantly on the oceans surface in definite directions. They are caused by differences in the temperature and salinity of water, by wind, solar heating and gravity. The winds majorly responsible for creating ocean currents are the Westerlies and the Trade winds. Warm ocean currents increases the temperature of the near by coastal areas while cold ocean currents bring down the temperature. What is the fastest way to harden salt dough? Ans.
