Sign up nowLong Questions - Weather, climate and Adaptation of Animals to Climate | Lakhmir Singh | Science | Class 7
What is meant by 'weather'? Name the elements which determine the weather of a place.
Weather refers to the day-to-day conditions of the atmosphere at a specific place and time. It includes various aspects such as temperature, humidity, precipitation, cloudiness, visibility, and wind. When discussing weather, meteorologists examine and report on these fluctuating atmospheric conditions. The elements that determine the weather of a place, also known as the 'elements' of weather, include the temperature, atmospheric pressure, humidity, wind speed and direction, sunshine, cloud cover, and precipitation (such as rainfall or snowfall). These factors collectively influence what we recognize and experience as weather at any given location.
What produces weather? Why does weather change so frequently?

Which of the following option best describes a tropical region ?
(a) hot and humid
(b) moderate temperature, heavy rainfall
(c) cold and humid
(d) hot and dry
The tropical region is characterized by its location near the equator, which results in certain climatic conditions. Here's how it matches the given options:
-
Hot and humid (option a): This option best describes a tropical region because such areas typically have high temperatures throughout the year and receive significant amounts of rainfall, leading to high humidity levels.
-
Moderate temperature, heavy rainfall (option b): While heavy rainfall is a feature of tropical regions, "moderate temperature" is not accurate as temperatures are generally high.
-
Cold and humid (option c): This does not describe tropical regions, as they are generally warm or hot, not cold.
-
Hot and dry (option d): Some tropical regions may experience hot conditions, but "dry" is not characteristic of most tropical climates, which are known for their rainfall.
Therefore, the answer is (a) hot and humid.
A carnivore with stripes on its body moves very fast while catching its prey. It is likely to be found in :
(a) polar regions
(b) deserts
(c) oceans
(d) tropical rainforests
