1.	Can folds form into block mountains? Find the reason and discuss.
Answer» No, folds cannot form into block mountains because folding takes place due to compression of elastic rocks and block mountains are formed due to displacement of rocks owing to tension.

2.	When can faults form is fold mountains?
Answer» If compression takes place along the faults, folds can be formed.

3.	A mountain never remains a mountain’. Can you relate this idiom with the mountain building process?
Answer» This happens because of continuous erosional activities taking place on the mountain sides. Running water glaciers, wind, volcanic activities keep on changing the surface of a mountain.

4.	Earthquakes are recorded with the help of ………………. instrument. (a) seismogram (b) seismograph (c) Richter scale(d) Mercalli scale
Answer» Correct option is (b) seismograph

5.	How will compressional forces affect brittle rocks?
Answer» The compressional forces will break the brittle rocks into pieces.

6.	Name the energy waves involved in this natural event.
Answer» Tsunamis were involved in this natural event where the tectonic plates moved horizontally.

7.	Identify the correct correlation:A – The structure of the interior of the earth is decided with the help of seismic waves. R – The S-waves travel in solid, liquid and gaseous medium while P-waves travel only through solid medium. (a) Only A is correct. (b) Only R is correct. (c) Both A and R are correct and R is the correct explanation of A. (d) Both A and R are correct but R is not the correct explanation of A.
Answer» Correct option is (a) Only A is correct.

8.	What actually happened during this natural event?
Answer» A very high intensity earthquake struck north eastern parts of Indonesian coastline, where subsequent landslides into sea triggered tsunamis.

9.	What was the cause behind these events?
Answer» Collision of tectonic plates was the causes behind the events.

10.	Identify the correct correlation:A – The origin of Himalayas is due to the collision of the Indian subcontinent with Eurasian landmass. R – The convergence of plates is often associated with mountain building. (a) Only A is correct. \(b) Only R is correct. (c) Both A and R are correct and R is the correct explanation of A. (d) Both A and R are correct but R is not the correct explanation of A.
Answer» (c) Both A and R are correct and R is the correct explanation of A.

11.	Identify the correct correlation.Assertion- Intensity of an earthquake is a measurement of the energy released during an earthquake. Reasoning – Mercallis scale is used to measure intensity of an earthquake. (a) Only A is correct. (b) Only R is correct. (c) Both A and R are correct and R is the correct explanation of A. (d) Both A and R are correct but R is not the correct explanation of A
Answer» (c) Both A and R are correct and R is the correct explanation of A.

12.	The …………….. are symmetrical in shape. (a) cinder cone (b) lava domes (c) volcanic plateau (d) composite cone
Answer» Correct option is (d) composite cone

13.	Sometimes, the lava material thrown into the air solidifies into small fragments before falling on the surface; it is called ………………(a) crock fragments (b) ash (c) volcanic dust (d) volcanic bombs
Answer» Correct option is (d) volcanic bombs

14.	The describes the intensity of an earthquake based on its observed effects. (a) Richter scale (b) Mercalli scale (c) seismogram (d) seismograph
Answer» Correct option is (b) Mercalli scale

15.	Identify the correct correlation:A – Volcanic activity coincides with seismic activity of the world. R – The seismic cone coincides with plate boundaries. (a) Only A is correct. (b) Only R is correct. (c) Both A and R are correct and R is the correct explanation of A. (d) Both A and R are correct but R is not the correct explanation of A.
Answer» (d) Both A and R are correct but R is not the correct explanation of A.
