Cold is the absence of heat, and thus is a product of the removal of the heat. When night falls, we experience the loss of what is called diurnal heating, or heating by the sun. This is caused by the lack of long wave radiation, radiation emitted by the sun directly on the planet, which produces heat as well as the loss of short wave radiation, energy released from the planet which was absorbed as long wave radiation.
It also depends on the season, which is caused by the angle of the Earth in relation to the sun. In the summer, the sun shines directly on the Tropic of Cancer (23 degrees 26'), causing more direct sunlight in the Northern Hemisphere to heat it up. In the winter, the sun shines on the opposite latitude known as the Tropic of Capricorn which causes less heat to generate in the Northern Hemisphere. The angle of the sun directly influences how hot and cold it becomes.
If you refer to a specific area, a city or state as opposed to the country or continent, then you need to look as what are called synoptic scale air masses and semi permanent air masses, which are bubbles of high and low pressure air that influence large regions. For example, in North America, Canada houses the Alberta High Pressure System, which commonly pushes cold air into the continental United States. As winter emerges, this air mass will move into the Central Plains. Smaller systems, known as high or low pressure systems, move throughout the world and affect local temperatures.
The parts of these systems are called the warm front, the cold front and the occlusion. The warm front is a mass of relatively warm air and the cold front is the relatively cold air. As these move over an area they will affect the temperature.
Ask your local weatherman for explanations of what systems are currently affecting your area, as they change daily.
It drops in temperature. It gets cold.
Your question assumes that the purpose for measuring the temperature is related somehow to human comfort.Your answer depends on whether you're describing air, water, food, or beverages.Seventy degrees is relative. If this is as high as the temperature gets, then you can say that seventy degrees is warm.If this is as cool as the temperature gets, then you can say that seventy degrees is cool.Seventy degrees is rarely considered 'hot' or 'cold' in the strictest sense and definitions of these words.
Depends if the air gets warm or cold
The temperature and density of the air masses. the air masses moves when hot air and cold air gets together
Mostly cold fronts ... because the amount of moisture that air can hold is determined by the temprature. Thus, if it gets colder, rain may fall.
Illinois enjoys extremes of temperature but also has all four season.
Everything will die if it is too cold. try dipping a lizard in liquid nitrogen. I guess it depends on how cold it gets. All cold blooded animals slow down and stop moving as the temperature drops.
When the temperature goes down in Kansas it gets cold
An Exothermic or cold blooded creatures internal temperature fluctuates with it external temperature.
Weather on mars is mostly cold. In the winter it is -200 degrees at the poles. The air temperature rarely gets above 32 degrees F.
It absolutely depends where in the Metro Vancouver you are. The downtown gets a temperature of -3C at its lowest. The suburbs and the mountain regions get much lower than that.
it gets hot and cold
It depends on how low the temperature is. For the vast majority of proteins, low temperatures will actually stabilize them (so long as it is above 0 oC). If the temperature gets below 0 oC the protein may denature. Although in most cases, the temperature has to be far below 0.
in the daylight is warm really hot mostly but when it gets darker mostly it gets darkeranwsered by manalaged 9 year 6
because it gets very cold at that temperature.
It gets hot and cold
That depends on the climate and season. Oil gets thick when it gets cold, so some oils are made thinner than others to compensate for the temperature that they tend to be used in.
