2. The heat imbalance can be transferred across the earth’s surface in two ways: ocean currents and winds.
Both wind and Ocean currents transfer heat from the tropics towards higher altitudes, if it blows from the poles
Heat is transferred from the Sun-warmed surface of the Earth to the cooler overlying troposphere via…
5. The variations in the intensity of the sunlight can cause temperature differences on Earth’s surface because of the concentrated sunlight of the equator which makes the surface warm and at the higher latitudes, where of course the sunlight spreads over a way larger and the area of the surface is at a cool temperature.…
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…
There are many cultural considerations that a medical assistant needs to be aware of when addressing issues related to the female reproductive system. Some of these considerations are: believes and practices of religion, values, and even the attitudes of the people with different cultures. The most important thing that a medical assistant should avoid is offending the patient and make it seem as if they are judging them. Everyone has different beliefs and that is perfectly fine. Medical assistant just need to remember that no patient is the same, for example: some cultures forbid communication about reproductive issues with a particular gender. As an MA, it is their job to make sure the patient is cared for and to just give them the support…
The primary source of Earths heat is the Sun. The atmosphere absorbs the heat transmitted from the sun by the use of conduction, convection, and radiation. (Ahrens 30) Radiation is the kind of heat that gives people sunburns because the skin absorbs the heat. The reason as to why pots and pans used for cooking have plastic or rubber handles is because of conduction. Conduction is the transfer of heat from one molecule to another within an element. So as the burner gets hotter the heat travels through the pot/pan and warms the water; now we have a process called convection. Convection is the vertical movement of warm air/water upward and cool air/water downward.…
Heat can be transported in the atmosphere by solar radiation. The earth then absorbs the solar radiation and then after that it will be change into heat, which will be suck back into the atmosphere. Conduction and turbulent eddies are other ways that heat raises back into the atmosphere. All heat being transported upward towards the atmosphere…
1. If the earth rotates in the opposite direction to that of today, with the aid of diagrams, describe the likely characteristics of the global atmospheric circulations. The sun heats the atmosphere more at the equator than it does at the poles. There would initially be a surplus of heat at the equator and a deficit at the poles which would be evenly distributed through oceans and the atmospheric circulation such as in Figure 1.…
The atmosphere retains some of the heat and energy via atmospheric windows and clouds. These clouds and atmospheric windows all emit their own energy. As well as clouds, greenhouse gases, the leading cause of global warming, maintain and refrain heat from leaving the oxygen hence why the globe is heating up. Greenhouse gases include carbon dioxide, which is why the greenhouse gas levels are rising at an alarming…
Global warming is the gradual increase in the temperature of the earth's atmosphere and oceans, mostly caused by the greenhouse effect. The greenhouse effect is where incoming short-wave solar radiation from the sun can pass through the earth’s atmosphere to reach the surface; some of this radiation is then reflected back into space at a longer wavelength. Greenhouse gases in the atmosphere absorb some of this long wave radiation and re-radiate it back to the earth’s surface, trapping heat in our atmosphere. There have always been natural fluctuations in the earth’s temperature, for the last 2.5 million years earth has shifted between cold glacial periods, and warmer interglacial periods. We are currently in an interglacial period, where the temperatures have been warm, with very small fluctuations for the last 10,000 years. Over the last century global temperatures have increased rapidly, there was a sharp rise in temperature between 1900 and 2000 of 0.7oC. Most scientists agree that this sharp increase was caused by human activities (anthropogenic). This continued increase in temperatures could have many major impacts worldwide, both positively and negatively.…
the earth is constantly going through periods of warming and cooling. The earth has a…
There is a scientific consensus that the recent rise in global temperature (global warming) is caused by human enhancement of the greenhouse effect, where greenhouse gases absorb outgoing long-wave radiation, so less is reflected back to space and is essential for keeping the planet warm. However, too much greenhouse gas in the atmosphere means too much energy is trapped and the planet warms up. One of the key findings in the IPCC report is the attribution of more than half the increase in global surface temperatures from 1951-2010 to human activities, underlining the dominant role of fossil fuel burning as a…
They say that the Earth warms and cools in a cyclical fashion, going to and fro through periods of warming, then cooling, then warming again. Some say that increased activity of the Sun is responsible.…
Around 30% of the sun's energy that reaches the Earth is reflected back into space. Changes in how much sunlight is absorbed, and how much is reflected, can affect global temperatures. Using satellite and land-based observations and computer models, scientists have calculated how Earth's reflectivity has changed over time.…
The mission statement for Colgate is “Our three fundamental values – Caring, Global Teamwork and Continuous Improvement – are part of everything we do.” (“Colgate world of,” 2011). Colgate presents products in the line of household and personal care such as laundry detergents, health care products and Hill pet food.…
If one was to compare and contrast Football and basketball, he/she would find many similarities and differences. Football and basketball are similar in having uniforms but differ in the number of players and the equipment that is required to be worn. In high school, the most enjoyable part of one’s Friday night will somehow include football and basketball games. Football and basketball are almost always recognized as the most important sports to a school. Contrary to what spectators may think, these two sports take effort by the players. Also in common is that they have to have a ball in order to play the sport. Even though they do not use the same ball, they have to have it to score with. Along with similarities, come differences. What players…
