Understanding the Weather Class 7 Assertion-Reason Type Questions
Two statements are given – Assertion (A) and Reason (R). Read them carefully and choose the correct option.
Question 1.
Assertion (A): Some thermometers are extraordinary instruments that measures both the maximum and minimum temperatures during a day.
Reason (R): The daily readings of the maximum and minimum thermometers are used to work out the average or mean temperature for one day.
Codes:
(a) Both A and R are true, and R is the correct explanation of A.
(b) Both A and R are true, and R is not the correct explanation of A.
(c) A is true, but R is false.
(d) A is false, but R is true.
Answer:
(a) Both A and R are true, and R is the correct explanation of A.
Reason: Since the Reason (R) correctly explains why thermometer both statements are true, and R correctly, explains A.
Question 2.
Assertion (A): The amount of rainfall is measured with the help of an instrument called in a container and a scale is used to measure the height of water.
Codes:
(a) Both A and R are true, and R is the correct explanation of A.
(b) Both A and R are true, and R is not the correct explanation of A.
(c) A is true, but R is false.
(d) A is false, but R is true.
Answer:
(a) Both A and R are true, and R is the correct explanation of A.
Reason: Since the Reason (R) correctly explains how a rain gauge works, both statements are true, and R correctly, explains A.
Question 3.
Assertion (A): People who travel to places at a high altitude are advised to go from one height to another over a period of time to allow the body’to acclimatise.
Reason (R): They are advised because as we go higher, the atmospheric pressure increases.
Codes:
(a) Both A and R are true, and R is the correct explanation of A.
(b) Both A and R are true, and R is not the correct explanation of A.
(c) A is true, but R is false.
(d) A is false, but R is true.
Answer:
(c) A is true, but R is false
Reason: Assertion A is true. However the reason given in R is incorrect because atmospheric pressure decreases, not increases, as we go higher.
Question 4.
Assertion (A): A wind vane shows the wind direction.
Reason (R): An anemometer is used to measure wind speed.
Codes:
(a) Both A and R are true, and R is the correct explanation of A.
(b) Both A and R are true, and R is not the correct explanation of A.
(c) A is true, but R is false.
(d) A is false, but R is true.
Answer:
(b) Both A and R are true, but R is not the correct explanation of A.
Reason: Both the statements are true, but R does not explain A, because an anemometer and a wind vane are two different instruments with different functions.
