This happens when the normal winds weaken which allows the warm water that is usually found in the western Pacific change direction and instead move towards the east. This warm water replaces the cold water which is normally found near the surface of the eastern Pacific. All these occurrences are what affects a lot of weather patterns in many parts of the
When the clouds meet cool air over land, precipitation (rain, sleet, or snow) is triggered, and water returns to the land (or sea). Some of the precipitation soaks into the ground. Some of the underground water is trapped between rock or clay layers; this is called groundwater. But most of the water flows downhill as runoff (above ground or underground), eventually returning to the seas as slightly salty water. The water moves from one reservoir to another, such as from river to ocean, or from the ocean to the atmosphere, by the physical processes of evaporation, condensation, precipitation, infiltration, runoff, and subsurface flow.
Hurricanes need the ocean’s water temperature to be about 80 degrees to a depth of about 150 feet. Another factor of the forming of hurricanes is the rapid cooling of the warm water vapors that were evaporated, which causes condensation (the second step of the water cycle). The third step of the water cycle is precipitation and that happens when too many water vapors are condensed and rain starts to fall. Humidity is also needed in the
This effect is caused mostly by the lack of vegetation and soil moisture in urban areas, which would normally use the absorbed sunlight to evaporate water as part of photosynthesis, which is known as a process is called evaportranspiration. Because urbanized land areas cover only a very small fraction of the Earth, the effect of the urban heat island on global average temperatures is very small. Most thermometers are located in urbanized areas; those areas tend to become more urbanized over time. Many buildings found in urban areas have dark surfaces. Dark surfaces absorb more light energy, and heat, making the entire building warmer.
An example of this can be found in glaciation. During glaciations the weight of ice pushing on the Earth can depress the crust, causing the land to fall relative to the level of the sea. When the ice goes in warmer periods the land rebounds upwards as Scotland and Northern Britain are today - rising relative to the level of the sea. Eustatic sea level change is a GLOBAL change in sea level, linked directly to the temperature of the Earth. In warmer periods there is less ice and the water is warmer, so expands and sea levels rise.
Convection, heat transfer in fluids (Liquids and Gases) is due to rising currents of fluid due to decrease in Density. Cooler fluid moves in to replace the rising current of fluid. This too, is heated and rises and a circulatory motion is set up within the Fluid. Radiation, the slowest of the Heat Transfer processes will only heat substances 'or bodies" in the direct path of the Heat Rays. Stand in front of a fire on a cold night.
Hot tub water was hot at 45 degrees Celsius. Blood vessels will dilate near the surface of the skin. Sweat to cool down the body temperature Did the air temperature have an effect on water temperature? The air was about 15 degrees Celsius which is much colder than the hot tub temperature. So the air temperature would cool the water down.
D. Scholar Geography 1 November 11, 2012 Test Corrections #1 Question: Which atmospheric heating process involves the emission of energy from an object? Correct Answer: E) Radiation My Answer: D) Why it’s Wrong: Radiation is the right answer because it has much stronger. It’s stronger than transmission, scattering, reflection and absorption. A good example would be: if your wearing a black shirt out in the sun you would be much hotter than if you’re wearing a white shirt. The black shirt would also fade over time because the suns rays would eat up the shirt.
Since air is less dense than water wind can only remove fine sediment such as silt, sand, and clay, but unlike running water, wind is not confined to channels. It can have a widespread effect over vast areas, and the faster the wind blows, the more sediment it can move. Wind action in dry climates can result in thick, choking dust storms. Air pressure differences cause wind as air warms and cools and changes density. The extreme temperature fluctuations that can occur in dry climates causes winds to become stronger.
First we must look at the greenhouse effect. As our text states the greenhouse effect are gases that are naturally found in our atmosphere. These gases trap heat as it escapes from the Earth’s surface. Greenhouse gases let sunlight in, which is good, but they prevent heat from escaping. This in turn naturally causes warmer temperatures.
