696: Consider the following statements :
1. Biodiversity hotspots are located only in tropical regions.
2. India has four biodiversity hotspots i.e., Eastern Himalayas, Western Himalayas, Western Ghats and Andaman and Nicobar Islands.
Which of the statements given above is/are correct ?
(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) Neither 1 nor 2
Explanation:
The British biologist Norman Myers coined the term "biodiversity hotspot" in 1988 as a biogeographic regio characterized both by exceptional levels of plant endemiism and by serious levels of habitat loss. Biodiversity hotspots are also located in temperate regions like Calfornia floristic province and Japan etc. Western Himalayas and Andaman and Nicobar Islands are not Biodiversity Hotspots.

698: Consider the following statements :
1. The Richter scale is a logarithmic scale and so an increase of 1 magnitude unit represents a factor of 10 times in amplitude.
2. Each integer reading of the Richter scale has an energy 100 times that of the previous integer reading.
Which of the statements given above is/are correct?
(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) Neither 1 nor 2
Explanation:
Richter scale is a logarithmic scale that runs from 1 to 9, though no upper limit exists. An increase of 1 magnitude unit represents a factor of 10 times in amplitude i.e. a magnitude of 8 quake is 10 times more powerful than magnitude of 7 quakes. Every increase of one number in magnitude means the energy release of the quake is 32 times greater. For example, an earthquake of magnitude 6.0 released 32 times as much energy as an earthquake measuring 5.0.
