Question

In the frigid zone annual rainfall varies from --
A. 5-10 cm
B. 10-15 cm
C. 15-30 cm
D. 20-80 cm

Answer 1

Hint: The diffusion of several kinds of flora and fauna relies on the climatic as well as other environmental aspects. The tropical rainforests harbor elevated biodiversity on earth.

Complete answer:
The earth is split into several climatic zones and the major factors of the varied climate are latitude, elevation, currents, correspondence to water bodies, and terrain. Based on distinctions in climatic conditions, there exist three climatic zones on the Earth, i.e. the tropical zone, the temperate zone, and the frigid zone. The frigid zone experiences severe cold climates and resides frozen virtually throughout the year. The flora is impeded to expansion in fewer winter months and significant animals are polar bears and other animals that can endure exceptionally cold situations. Close towards the equator, the temperate zone which obtains extensively colder climates. The climatic conditions boost the growth and survival of a large variety of flora and fauna and the highest of the rainforests of the world occur in this climatic belt. Rainfall may vary from 15cm to 30 cm in a year. Only during the quick summer season, some extremely lowly plants may thrive only in the regions away from the polar ice caps. These areas are recognized for blizzards and occupy regions of the Arctic margins of North America and Eurasia and the Antarctic continent.

Thus, option C) is the correct answer.

Note: As it obtains nearer to the equator, the temperature and quantity of rainfall increases, giving rise to the climate hot and humid. This area is the torrid zone. It obtains direct rays of the sun and suffers heavy rainfall throughout the year.
