Answers
Answer:
answer1
exposure to the sun's rays
answer2
Did you mean: 2. Why does only a small fraction of the total solar radiation reaches the surface of the Earth?
Solar radiation that is not absorbed or reflected by the atmosphere (for example by clouds) reaches the surface of the Earth. The Earth absorbs most of the energy reaching its surface, a small fraction is reflected. ... The Earth radiates energy at wavelengths much longer than the Sun because it is colder.
answer3
The sun generates energy from a process called nuclear fusion. During nuclear fusion, the high pressure and temperature in the sun's core cause nuclei to separate from their electrons. Hydrogen nuclei fuse to form one helium atom. ... Yet this amount of energy is enormous.
answer4
Six's thermometer is a registering thermometer which can record the maximum and minimum temperatures reached over a period of time, for example 24 hours.
answer5
Stevenson screen (also known as an instrument shelter) is a meteorological screen to shield instruments against precipitation and direct heat radiation from outside sources, while still allowing air to circulate freely around them.
answer6
Daily mean temperature: It is calculated by adding the maximum and minimum temperature of the day and dividing the total by two. The monthly mean temperature: It is calculated by adding the daily mean temperatures for the each day of the month and dividing the total by the number of days in a month
answer7
The difference between the maximum and minimum daily temperatures is known as the Diurnal temperature range. The difference between the hottest and coldest months, with monthly mean temperatures, is called the annual temperature range in each case.
answer8
gether with the longitudes, latitudes are used to indicate a precise location of any feature on the earth's surface. Temperature is inversely related to latitude. As latitude increases, the temperature falls, and vice versa. Generally, around the world, it gets warmer towards the equator and cooler towards the poles.
answer9
Seasonal variations in temperature and precipitation occur around the world because of the effect of the Earth orbiting around the Sun. ... Countries near the equator are cooler than the desert areas because much of the heat energy is used in evaporating the large volumes of precipitation that fall there.
answer10
Its Allahabad ...
the reason is that it lies in the interior so it is not infulinced by the sea and hence has a continental type of climate
answer11
Background: Warm and cold ocean currents can affect the climate of an area along the coast if the winds blow in from the ocean. Warm ocean currents heat the air above the water and carry the warm air to the land, increasing the temperature of the coastal region.
answer12
The winds affect the climate because they create the hot and cold air which moves around. Prevailing winds affect the climate of an area. ... When winds blow from warm areas, they carry higher temperatures while winds blowing from cold areas carry lower temperatures.
answer13
Near the Earth's surface, air gets cooler the higher you climb. As you climb a mountain, you can expect the air temperature to decrease by 6.5 degrees C for every 1000 meters you gain. This is called the standard (average) lapse rate.
