These three things plus the sun's heat determine where rain falls on the planet. The sun shines almost vertically on the equator year round, but it shines on the poles at a steep angle. There are two consequences. A beam of sunlight ten square feet shines on about ten square feet of Earth's surface at the equator, but it covers more than twice that area near the poles. The sun's light and heat are less concentrated at higher latitudes.
Normal conditions, before El Nino events occur, strong trade winds move surface waters westward. As this occurs the water becomes warmer. When water becomes warmer it causes the air to rise and cool causing torrential rainfall. When El Nino occurs there a warm upper ocean layer, which is poor in nutrients and a cold lower ocean layer, which is rich in nutrients. The cold water is brought when the surface current flows westward in a process known as upwelling.
Though together they are specifically referred to as evapotranspiration. Condensation occurs as the vapor rises into the sky, creating clouds and fog. Once clouds are formed, the movement of water in states through the
Together these things work to create ocean currents that help in the overall vitality on our earth dynamic surface. Wind is one of the largest indicators for ocean currents. It works by circulating differential heating around the world helped by our equators warm belt, our poles cold points, and the Corialis effect. The Corioles effect is the deflection of moving objects when they are viewed in a rotating reference frame. Our rotating reference frame is the earth, and its large mass and slow rotations the force is quite small.
The objective was to create structures of the weather using household items and use them to analyze data. The first weather instrument is the aneroid barometer. A aneroid barometer is an instrument that measures changes in air pressure without using a liquid. When wind blows, it says either very high, high, 0, low, or very low. The second instrument is called a thermometer.
A distinct correlation between the pattern of ocean currents and the air circulation above them can be made. The major ocean currents are wind-driven currents, though some ocean currents result from density and salinity variations of water. The subtropical high pressure cells are responsible for many of the Earth's great ocean currents. Examine the location of the subtropical highs and then place their position on the map of world ocean currents. See any correlation?
Some of this long wave terrestrial radiation travels upward, where it may be reabsorbed by other gas molecules. The remainder travels downward and is again absorbed by the earth. Thus, the earth’s surface is being continually supplied with heat from atmosphere as well as from the sun. These processes that take place between the earth’s surfaces will keep the earth average temperature warmer than it would otherwise be. Plate tectonics could also led to climate change.
There are rain forests in this region, due to the more humid, rainy climate. In the southern region, the mountains are nearer to the Antarctic and it is much colder. It is not very populated in the southern area. In the central region of this biome, the weather is more mild because it is not near either the equator or the cold Antarctic - . Where are the Andes?
Quantity refers to the intensity or concentration of sunlight and varies with the season of the year. Quality refers to the color or wavelength reaching the plant surface. Sunlight can be broken up by a prism into red, orange, yellow, green, blue, indigo, and violet. Duration refers to the amount of time a plant is exposed to sunlight or the lack of it’s designated photoperiod. Temperature: Temperature affects the productivity and growth of a plant, depending upon whether the plant is a warm- or cool-season crop.
3.0 Theory The shape of an aerofoil causes the air along the top surface to speed up resulting in a negative pressure and the air on the lower section slow down resulting in a positive pressure. The combination of these two pressure regions leads to a lift force being generated. The following are the formulas used in determining the required values: Drag Force, FD=12CDρAv2 Lift Force, FL=12CLρAv2 Velocity of Flow, v=2∆Pρ Pitching Moment, M=CmqSc 4.0 Experimental Apparatus The following are the apparatus involved in the experiment: * LS 18013 educational wind tunnel * 3 Components Balance * Test Model * Test
