Ocean currents
Part 1:
1. Describe four factors that influence ocean currents.
There are many factors that influence ocean currents, four of the factors would be planet rotation, wind, density of water, and gravitation. Planet rotation causes the currents to move clockwise in the northern hemisphere and counter clockwise in the southern hemisphere. Wind blows on the surface of the ocean therefore pushing the water in the direction of the wind. Different densities in the water can cause currents to form and move. Gravitation pulls the water “downhill.”
2. Explain how the Coriolis Effect impacts ocean currents.
The Coriolis effect controls the wind. Then the wind affects the ocean currents.
3. What is the relationship between ocean currents and climate?
The ocean is a major component of the climate system, it covers about 71% of the enitre earth, and it absorbs almost twice as much of the sun's radiation than the atmosphere or the land does. It controls a lot of the weather and how it reacts.
4. What is upwelling and why is it important to the marine ecosystem?
Upwelling is when the cold water from the deepest part of the ocean rises to the surface. When the cold water comes to the surface it brings massive amounts of nutrients that have been accumulating over the year at the bottom of the ocean.
5. Explain the relationship density has on wind currents and ocean currents.
When the temperature of the wind and the ocean gets higher, the density decreases, just like when the temperature of the wind and ocean gets lower, the density increases. Movement of the currents is driven by density. The movement occurs in the space between water molecules when it increases due the temperatures.
6. Which factor in creating currents has the greatest influence on weather patterns?
The wind and earth’s rotation has the greatest influence on weather patterns due to the increase of movement in the currents and the change of temperatures as the seasons change.

    All currents in the northern hemisphere move in a clockwise direction, while in the southern hemisphere they move in an anti-clockwise direction. Suprisngly landmasses can be responsible for changing the course of a current. Differences in temperature and salinity are also responsible for the movement of ocean water. In the equatorial region, ocean water gets more heated than in the cold polar regions. This makes the water “light”. Water in the polar regions is cold and heavy, so it sinks and flows towards the equator. The light upper layers of water are thus forced to move towards the poles where they get cooled. Some effects are winds blowing. Winds blowing over a warm current can become warm, and at the same time, pick up moisture, as warm winds are able to retain more moisture. Therefore, the wind that reaches the land brings down the temperature and can cause heavy rain. The western coast of Europe for example, is one. Winds blow cold and dry air. They help to bring down the temperatures in places, which would have been much hotter. The California current which is cold, which flows along the western coast of the U.S, makes the region much cooler than other places in the west coast on…

    Explain what causes the "sea breeze" and "land Breeze". A “sea breeze” forms during the day as the land heats more quickly than the near by water which creates a shallow thermal low (warm air rising over land). The air remains cool over the water, which creates a shallow thermal high. (cool air sinking). The high pressure moves toward the low pressure and creates a wind that blows from the water to the land.…

    Volcanoes affected the origins of the sea by pouring huge amounts of steam into the atmosphere. This would result in the process of condensation. The volcanoes would pour steam and the Earth would cool down, which lead to condensation. The process caused water to fill up the hollows on Planet Earth, which formed it’s seas.…

    5. How do warm currents become heated? How do cool currents become cooled? Water is an enormously efficient heat-sink. Solar heat absorbed by bodies of water during the day, or in the summer, is released at night, or in winter. But the heat in the ocean is also circulating. Temperature & Salinity control the sinking of surface water to the deep ocean, which affects long-term climate change.…

    As the earth warms the water expands and gets higher. This can cause a safety hazard for humans, plants and animals. Can also create powerful storms on low-lying areas. The warmer the surface of the water it will make it easier for small ocean storms to enlarge and become more dangerous than what they already are. These storms also make it dangerous for marine ecosystems and gives sensitive habitats less time to recover.…

    Winds and currents move the surface of the water causing waves. The gravitational attraction of the moon causes the oceans to bulge in the direction of the moon. Another bulge occurs on the opposite side because the Earth is also being pulled toward the moon and away from the water on the far side. Ocean levels fluctuate daily as the sun, the moon, and the earth interact. As the moon travels around the earth and as they, together, travel around the sun the combined gravitational forces cause the oceans to rise and fall.…

    3. What is an ocean current? Surface ocean currents are caused by winds. Wind presses on the ocean's surface and forces the water to move along with it. These currents range from 50 to 100 meters in depth and are contained to the surface layer. Deep ocean currents are caused by several factors including temperature and salinity, which accounts for the water's density.…

    Jet Streams: Earth’s weather is strongly influenced by atmospheric conditioned and events that occur at the boundaries between wind zones. On either side of these imaginary boundaries, both surface and upper-level air differs greatly in temperature and pressure. Remember that wind, temperature, and pressure are related. Differences in temperature and pressure cause wind. Therefore, a large temperature gradient in upper-level air should result in strong westerly winds, and indeed, this is what happens. Narrow bonds of fast, high-altitude, westerly winds called jet streams flow at a speed up to 185 km/h at elevations of 10.7 km to 12.2 km. Jet streams, are named because they resemble jets of water. The most significant one, the polar jet stream, separates the polar easterlies from the prevailing westerlies. A second version, the subtropical jet stream, is located where the trade winds meet the prevailing westerlies.…
