This ecosystem experiences high average temperatures and a significant amount of rainfall. Tropical rainforests are unique in the high levels of biodiversity they exhibit. Around 40%’ to 75%’ of all biotic species are indigenous to the rainforests. Rainforests are home to half of all the living animal and plant species on the planet. Twothirds of all flowering plants can be found in rainforests. A single hectare of rainforest may contain 42,000 different species of insect, up to 807 trees of 313 species and 1,500 species of higher plants. Tropical rainforests have been called the “jewels of the Earth” and the “world’s largest pharmacy”, because over one quarter of natural medicines have been discovered within them.

B.  Isohyets
C.  Isohalines
D.  Isotherms

Correct Answer:-D ( Isotherms )
Description:-  An isotherm is a line on a map or chart of the earth’s surface connecting points having the same temperature at a given time or the same mean temperature for a given period. Isotherm maps show where temperatures are relatively high and low, and also where temperature changes are gradual or dramatic over a distance.

Correct Answer:-B ( Topographic maps )
Description:-  A topographic map is a type of map characterized by large-scale detail and quantitative representation of relief, usually using contour lines in modern mapping, but historically using a variety of methods. A topographic map is typically published as a map series, made up of two or more map sheets that combine to form the whole map.


62.  Contour line is the imaginary line joining places of equal :

A.  Rainfall
B.  Humidity
C.  Elevation
D.  Temperature

Correct Answer:-C ( Elevation )
