Differentiate between
(a) weather and climate
(b) humidity and rainfall
(c) climates of polar region and tropical rainforest
(d) maximum and minimum temperatures of the day [NCERT Exemplar]
Answers
Answer:
(A) Weather is the day-to-day state of the atmosphere, and its short-term variation in minutes to weeks. People generally think of weather as the combination of temperature, humidity, precipitation, cloudiness, visibility, and wind. ... Climate is the weather of a place averaged over a period of time, often 30 years.
(B)Humidity is a measure of water vapor in the air. It is possible to have 100% humidity and have no rain (that is what fog is). Rainfall occurs when there is more than enough moisture in the air to condense around particles in the air to form raindrops (raindrops cannot condense without those particules). Because of that you can have humidity without raindrops.
(C)1) Climate is hot and humid in tropical rain forest whereas polar regions are cold.
2) Polar regions are permanently covered with snow whereas tropical rain forest has heavy rain falls.
3) Less vegetation is found in polar areas whereas tropical rainforest have wide variety of vegetation.
(D)The temperature difference between daily maximum and minimum temperatures is known as the diurnal temperature range. The much-reported decrease in the diurnal temperature range has been said to be one of the “fingerprints” of human-induced global warming.
