Approximately how many kilometers are represented by 1 degree of latitude?
Explanation:
Approximately 1 degree of latitude is equivalent to about 111 kilometers. This value varies slightly due to the Earth's slightly oblate shape, but for most practical purposes, 111 kilometers per degree is a useful approximation for navigation and geographical calculations.

Examine the two statements carefully then select the correct answers:
Statement I: Anticyclone, which is a high-pressure wind system, does not bring about significant change in weather conditions
Statement II: The outward movement of wind from the high-pressure center keeps limited scope for disturbance.
Explanation:
Statement I accurately describes anticyclones as high-pressure wind systems that generally do not bring significant changes in weather conditions. Statement II correctly explains the outward movement of wind from the high-pressure center but does not directly explain why anticyclones do not bring about significant weather changes. Therefore, there is no direct explanatory link between the two statements.
The broken hills famous for zinc and lead are located in:
Explanation:
Broken Hill is a mining town in the far west of outback New South Wales, Australia. It is known for its rich deposits of silver, lead, and zinc, making it one of the largest mining areas in the world.
El Nino associated with the formation of the South-West monsoon of India is ____________.
Explanation:
El Niño refers to the abnormal warming of ocean waters in the central and eastern Pacific Ocean, which can significantly impact global weather patterns, including the Southwest monsoon of India. This warm ocean current disrupts the normal atmospheric circulation patterns, leading to changes in weather conditions worldwide.
Which of the following rivers does not flow into the Bay of Bengal?
Explanation:
The Tapti River does not flow into the Bay of Bengal. It originates in the central part of India and flows westward, eventually emptying into the Arabian Sea. On the other hand, the Godavari, Mahanadi, and Cauvery rivers all flow into the Bay of Bengal.
Which of the following statements regarding the ozone layer within the atmosphere is/are correct?
1. It absorbs most of the ultraviolet radiation found in the Sun’s rays.
2. Chlorofluorocarbons are a serious threat to the ozone layer.
Select the correct answer using the code given below:
Explanation:
Statement 1 is correct: The ozone layer absorbs most of the ultraviolet (UV) radiation from the Sun's rays, which helps protect life on Earth from harmful UV radiation.
Statement 2 is also correct: Chlorofluorocarbons (CFCs) are indeed a serious threat to the ozone layer. When released into the atmosphere, CFCs break down ozone molecules, leading to ozone depletion. This depletion can result in the formation of the ozone hole, particularly over Antarctica.
Examine the two statements carefully then select the correct answers:
Statement I: El Nino is a temperature-rising phenomenon over the Pacific Ocean and usually causes dry monsoons in South Asia.
Statement II: Tsunamis are usually not noticed as the massive ocean waves move silently but assume destructive form as these travel through shallow waters of continental shelves.
Explanation:
Statement I correctly describes El Nino as a temperature-rising phenomenon over the Pacific Ocean, which indeed causes dry monsoons in South Asia. Statement II accurately describes tsunamis as initially unnoticed but becoming destructive as they reach shallow waters. However, there is no direct explanatory link between the two statements.
Which one of the following is not a formal agency of social control?
Explanation:
Teachers are not typically considered formal agencies of social control. Formal agencies of social control are institutions like courts, police, and sometimes family, which enforce societal norms and regulations through established legal or authoritative means.

Name the continents that form a mirror image of each other.
Explanation:
The correct answer is (c) Africa and South America. These two continents are often described as forming a mirror image of each other due to the way their coastlines fit together like pieces of a puzzle. This observation provided early evidence for the theory of continental drift and plate tectonics.
Which of the following cities will never get the vertical rays of the Sun?
Explanation:
Srinagar, located in the northern part of India, is situated at a higher latitude where it will never receive vertical rays of the Sun. Vertical rays occur between the Tropic of Cancer and the Tropic of Capricorn, which Srinagar is situated north of. In contrast, Chennai, Mumbai, and Kolkata are located closer to the equator and have the potential to receive vertical rays of the Sun at certain times of the year.
