Hi Everyone!! This article will share Our Quaking Planet Questions & Answers.
In my previous posts, I have shared the questions & answers of Environmental Pollution, A Dialogue and The Girl on the Train so, you can check these posts as well.
Our Quaking Planet Questions & Answers
Question 1: What is an earthquake?
Answer: An earthquake is a sudden violent shaking of the earth.
Question 2: What is a seismograph?
Answer: A seismograph is an instrument that measures and records information about earthquakes.
Question 3: What is a tsunami? Give an example of it.
Answer: A tsunami is an unusually large sea wave produced by an earthquake. On March 11, 2011, a deadly tsunami killed over 21,000 people and caused widespread destruction in Japan.
Question 4: What causes so many deaths in an earthquake?
Answer: In fact, it is not the earthquake that kills so many people. It is the tumbling buildings, the collapsing multi-storeyed flats and the shattering doors and windows that kill so many people.
Question 5: What causes a particularly powerful earthquake?
Answer: It is the movement of tectonic plates that causes a particularly powerful earthquake.
Question 6: What positive point, if any, do earthquakes have?
Answer: It is the collision of tectonic plates that causes powerful earthquakes. When these plates collide, new soil from deep under the ground is thrown up. Some of the old soil sinks back between the plates again. Thus, we get a fertile new soil which makes our planet so full of life.
Question 7: What factors can cause small tremors in the earth?
Answer: Small tremors can happen when volcanoes erupt. A landslide can also cause a slight tremor. There can be a small tremor when the roof of an underground cave falls in.
Question 8: What are tectonic plates? How do they cause earthquakes?
Answer: There are about twenty solid rocks in the earth’s crust. We call them tectonic plates. They are constantly moving, but very slowly. Sometimes, these plates get locked together and cannot move. When this happens, pressure begins to build up. Then one day suddenly, the locked plates break free, and there is a big earthquake.
Question 9: What can be done to escape the dangers of an earthquake?
Answer: To escape the dangers of an earthquake, we should use earthquake-resistant materials to construct our buildings.
Question 10: What can we do about earthquakes? Can they be controlled?
Answer: Earthquakes are beyond man’s control. We can do nothing about them. We can only try to minimize the damages when an earthquake happens.
Question 11: What horrible thing happened in Gujarat on 26 January, 2001?
Answer: On this day, an earthquake happened that killed about 20,000 people.
Question 12: How does a seismograph show the intensity of an earthquake?
Answer: A seismograph has a revolving drum. It has also a weight that hold a tracer. When there is a tremor in the earth, the weight begins to vibrate. The vibrations get traced on the turning drum through the tracer. The fluctuations in the traced line indicate the intensity of the earthquake.
Question 13: Write True or False:
1. A landslide cannot cause a big earthquake – True
2. Mud houses fall easily during an earthquake – False
3. Tectonic plates destroy the fertility of the soil – False
4. A seismograph can record only weak earthquakes – False
5. We can prevent earthquakes by making wooden houses – False
6. We can construct buildings that won’t fall in an earthquake – True
7. An earthquake always causes a great loss of life and property – False
8. Big earthquakes are caused when locked tectonic plates break free – True
Question 14: Choose the most appropriate meaning of the underlined word in each sentence:
1. Earthquakes are beyond man’s control.
(a) out of
(c) more than
2. Panic can only aggravate the situation.
3. Earthquakes have a positive point also.
4. We have probably a million earthquakes a year.
(a) ten lac
(b) one lac
(c) one hundred lac
5. Mud can withstand the tremors of an earthquake.
6. Earthquakes are much more common than most of us think.
