 Question 1
Which of the following statement is true about konkan coast?
1. It extends from Mumbai to South Karnataka.
2. Annual range of temperature is high.
3. It receives rainfall by the Arabian Sea branch of Southwest monsoon.
Which of the given below code is correct?
 A 1, 2 and 3 B 3 only C 2 and 3 only D 1 and 3 only
Question 1 Explanation:
India's climate is controlled by a number of factors which can be broadly divided into two groups - factors related to location and relief, and factors related to air pressure and winds.
With a long coastline, large coastal areas have an equable climate. Areas in the interior of India are far away from the moderating influence of the sea. Such areas have extremes of climate. That is why the people of Mumbai and the Konkan coast have hardly any idea of extremes of temperature and the seasonal rhythm of weather. On the other hand, the seasonal contrasts in weather at places in the interior of the country such as Delhi, Kanpur and Amritsar affect the entire sphere of life. So, Statement 2 is incorrect. "
 Question 2
Which of the following are true
1. Energy released during earthquake travels in all directions
2. The energy gets released due to friction between rocks in earthquake
Select the right code
 A 1 only B 2 only C Both D None
Question 2 Explanation:
• An earthquake in simple words is shaking of the earth. It is a natural event. It is caused due to release of energy, which generates waves that travel in all directions.
• The release of energy occurs along a fault. A fault is a sharp break in the crustal rocks. Rocks along a fault tend to move in opposite directions. As the overlying rock strata press them, the friction locks them together. However, their tendency to move apart at some point of time overcomes the friction. As a result, the blocks get deformed and eventually, they slide past one another abruptly. This causes a release of energy, and the energy waves travel in all directions.

 Question 4
Consider the following statements about 'zooxanthellae'?
1. They can be found in jellyfish.
2. They flourish in high temperatures.
Which of the above statements is/are correct?
 A 1 only B 2 only C Both 1 and 2 D Neither 1 nor 2
Question 4 Explanation:
Statement 1 is correct. Zooxanthellae are tiny plant-like organisms called zooxanthellae live in the tissues of many animals, including some corals, anemones, and jellyfish, sponges, flatworms, mollusks and foraminifera.

These microscopic algae capture sunlight and convert it into energy, just like plants, to provide essential nutrients to the corals. In exchange, they have a place to live inside the animal's body. But when the zooxanthellae are under stress, such as high temperatures, they will die or leave their host-a process known as bleaching.

 Question 5
