Weather, Climate & Adaptations of Animals to Climate Test - 7

The summer solstice or the longest day occurs sometime between June 20 and June 22 in the northern hemisphere, so the option which best matches the context is 22^nd June.

The winter solstice occurs between December 21 and December 23. Hence, option 2 is the correct answer.

A hygrometer is an instrument used for measuring the moisture content in the atmosphere.

A rain gauge is a device for collecting and measuring the amount of rain which falls.

The maximum recorded temperature in India is 51 degrees Celsius and in Greece it is 48 degrees Celsius. Canada and Greenland are closer to the poles and hence comparatively colder regions.

The nature of soil does not affect the temperature because soil has nothing to do with temperature. Density of population and pollution have direct impact on the temperature; the more are these factors, the more is the temperature. Trees have a vice versa impact on the temperature; more trees means lesser temperature as they act as a coolant, but soil has no such relation to the temperature.

Ans-1 Humidity
Humidity is the amount of water vapour present in air. Water vapour, the gaseous state of water, is generally invisible to the human eye. Humidity indicates the likelihood for precipitation, dew, or fog to be present. The amount of water vapour needed to achieve saturation increases as the temperature increases.

Camels are called "ships of the desert" because of their numerous and unique physical traits that enable them to survive in harsh desert climates, particularly their ability to consume very little water without dehydrating.

The Himalayas block the summer monsoon winds and cause precipitation in vast parts of northern India, which supports agriculture in plains of Ganges and Indus. It also blocks the cold winds coming from Central Asia and Siberian region.

Blubber is a thick layer of vascularised adipose tissue found under the skin of all cetaceans, pinnipeds and sirenians.
So, the correct option is 2.

Elephants are found in warmer regions only and cannot survive in cold climates. Hence, option 3 is the correct answer.

Fennec fox has distinctive, bat-like ears that radiate body heat and help keep the foxes cool. Hence, option 1 is the correct answer.
