a. If there was no rotation of the earth, winds would move directly from low to high pressure areas in a “straight” line. The rotation of the earth is referred to as the Coriolis effect, and in effect, the winds would move in direct lines from higher to lower pressure areas to create equilibrium, however the earth wouldn’t be turning, negating the spiraling effect of the Coriolis effect.…
When warm, light air begins to rise it does not push so hard against the earth, this is low pressure. Colder, heavier air sinks downwards pushing on the earth more, this is high pressure.…
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…
Effect of earths rotation tends to deflect air/water toward right in Northern hemisphere and left in Southern hemisphere…
1. Assume that you have 100 years of continuous temperature records from your local weather service office. Discuss some of the difficulties you might have trying to determine whether average temperatures have increased during this period.…
P.1:1. Swirling in complex patterns, air moves constantly across Earth’s surface. Wind, which is the horizontal movement of air, helps to moderate surface temperatures, distribute moisture, and generally cleanse the atmosphere.…

Because the light from the sun has passed a long distance through air and some of the blue light has been scattered away. If the air is polluted with small particles, natural or otherwise, the sunset will be redder. Sunsets over the sea may also be orange, due to salt particles in the air. The sky around the sun is seen reddened, as well as the light coming directly from the sun.…
8. The three abiotic spheres are the Atmosphere, Hydrosphere and the Lithosphere. Each one of these spheres interacts with each other and the biosphere in unique and different ways. The atmosphere works with the biosphere in that it uses the gases released from living things to form itself. It also receives gases from the Lithosphere, or the earths crust to help form itself. The atmosphere helps all living things survive by keeping an oxygen rich environment and keeping out harmful rays from the sun. The lithosphere helps control the movement of heat from within the earths crust to help make it possible for life to survive. It also is part of the soil layer which is essential to plant life. The Hydrosphere is very important because it has all the water on earth. This is in the form of ice sheets, liquid or vapor, and they are all essential to the survival of living things.…
A: Cultural geography centers on things such as people, religions, languages, foods, and traditions, While physical geography centers on the aspects of the earth, the soil, the mountains, water, landforms etc.…
· Explain the forces that drive gloabal circulation patterns and how those patterns determine weather and climate: Unequal heating of the Earth by the Sun, atmospheric convection currents, the rotation of the Earth and the Coriolis effect, Earth's orbit around the sun on a tilted axis, and ocean currents. The tilt of the Earth's axis of rotation causes the seasonal changes in temperature and percipitation as earth orbits the Sun.…
Cyclones experience air that converges and rises, creating low pressure at the surface. Northern hemisphere cyclonic circulations are mirrored in the southern hemisphere. For instance, in the northern hemisphere winds move counterclockwise and in the southern hemisphere winds move clockwise following the geostrophic pattern resemblance to isobars. In the northern hemisphere the wind flow pattern joins cool air that is from the north with warm air that is from the south. Then two fronts are created. A cold front extends to the southwest from the center along the pressure trough and a warm front extends eastward from the center consecutively along a, typically weaker, pressure trough. Different sectors are then created. A cool sector is along northern and western sides of the center and a warm sector is along the southern and eastern sides. The majority of the cool sector is at the surface and the warm sector is more widespread aloft as the cold air pushes up the warm…
By the global conveyor belt transferring heat, it affects the climate. The Gulf Stream is a part of the thermohaline circulation, it is another current that allows Western Europe to be warmer in winter then any other country at the same latitude. The La Niña can be referred to as the extensive cooling of the Pacific Ocean, it is often accompanied by much warmer sea water then the surface temperatures (SSTs) in the western Pacific Ocean, and the north of Australia. The El Niño is currently the best known extreme of the Southern Oscillation, it is also classified as one of the most important influences on the climate in Australia. (Pearson, 2015). Surface currents keep the Earth's temperatures normal. As surface currents travel, they absorb the heat from the tropical regions surrounding the equator and release it into the colder regions near the North and South Pole. Deep water currents move extremely slow,…
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.…
The Coriolis effect is due to the rotation of the Earth and causes water to move to the right in the northern hemisphere and to the left in the southern hemisphere. This means that the direction of surface ocean currents is not determined entirely by wind direction, by is deflected by the Coriolis effect.…
