Question

Why does weather change frequently?
A. Because of humidity.
B. Because of the temperature.
C. Because of rainfall.
D. All of the above.

Answer 1

Hint: Change in weather is a phenomenon that is influenced by various factors. The study of weather is known as meteorology. The person who studies various weather phenomena is known as a meteorologist.

Complete answer: Definition –
Weather – Weather is the state of the atmosphere, describing the degree to which it is hot or cold, wet or dry, calm or stormy, clear or cloudy.
Weather is influenced by air pressure, temperature, and moisture differences between one place and another. These differences can be experienced due to the Sun's angle at any particular spot, which varies with latitude. The strong temperature contrast between polar and tropical air causes the largest scale atmospheric circulations –
1. The Hadley cell
2. The Ferrel cell
3. The polar cell
4. The jet stream.
Weather variations in the middle latitudes, such as extratropical cyclones, are caused by instabilities of the jet streamflow. The Earth's axis is tilted relative to its orbital plane, so sunlight is incident at different angles at different times of the year. On Earth's surface, temperatures usually range ±40 degrees Celsius (−40 degrees Fahrenheit to 100 degrees Fahrenheit) annually. Weather change occurs primarily due to air pressure, temperature, and moisture differences between one place to another. These differences can occur due to the sun’s angle at any particular spot, which varies by latitude from the tropics.

Therefore, the answer is option D.

Additional information:
Weather, when seen from an anthropological perspective, is something all humans in the world constantly experience, through their senses, at least while being outside. There are socially and scientifically constructed understandings of weather, what makes it change, the impact it has on humans in different situations, etc. Therefore, the weather is something people communicate about often.

Note: Weather and climate are different phenomena yet they are related to each other. The short term conditions over a given area are known as weather. The long term aggregate of weather conditions over a given area is called climate.
