Answer / Steps:
Q. Study the globe and write in the space given below, when it is daytime in India, which countries will have night?
Ans: When it is daytime in India, countries located roughly on the opposite side of the Earth experience nighttime due to the Earth's rotation. For example, when India has daylight, countries like the United States, Canada, Brazil, Mexico, and parts of South America, as well as some regions in Australia and South Africa, will have night. This happens because the Earth rotates on its axis, so the side facing the Sun has day, and the opposite side has night. Thus, while India is in daytime, many Western countries in the Americas are in nighttime.
