Climate Ch (4) Practice Quiz in English Part 2 || Class 11 Geography Book -2 Practice Quizzes in English

Explanation: It is predicted that the average sea level will rise by about 48 cm by the end of the 21st century, increasing the risk of coastal flooding.

Explanation: The regions receiving rainfall between 100-200 cm annually include the southern parts of Gujarat, east Tamil Nadu, northeastern Peninsula covering Odisha, Jharkhand, Bihar, eastern Madhya Pradesh, northern Ganga plain along the sub-Himalayas, and the Cachar Valley and Manipur.

Explanation: The Indian Meteorological Department (IMD) is responsible for monitoring weather conditions across India and providing forecasts, including crucial information about the monsoon season.

Explanation: El Nino can influence the Indian monsoon by causing irregularities such as delayed onset, variations in rainfall patterns, and even droughts.

Explanation: The monsoon is crucial for India’s agricultural cycle, as a significant portion of the population depends on agriculture, which is heavily reliant on the southwest monsoon for water.

Explanation: Global warming can lead to the melting of glaciers and sea ice, resulting in a rise in sea level, which can have significant impacts on coastal regions.

Explanation: The regions receiving rainfall below 50 cm annually include parts of the Peninsula, especially in Andhra Pradesh, Karnataka, and Maharashtra, Ladakh and most of western Rajasthan.

Explanation: The “October heat” refers to the oppressive weather conditions in October characterized by high temperatures and humidity after the retreat of the southwest monsoon.

Explanation: The cyclonic depressions that bring rainfall to the Coromandel coast during the retreating monsoon season typically originate over the Andaman Sea and move towards the eastern coast of the southern Peninsula.

Explanation: The greenhouse effect occurs when solar radiation is absorbed by the Earth’s surface and then re-emitted as longwave radiation. Greenhouse gases in the atmosphere absorb this longwave radiation, trapping heat and warming the planet.

Explanation: The increasing levels of carbon dioxide in the atmosphere, primarily caused by human activities like the burning of fossil fuels, are a major concern in the context of global warming.

Explanation: Weak temperate cyclones, also known as western disturbances, originating from the Mediterranean Sea, bring some rainfall to northwestern India during winter, which is beneficial for rabi crops.

Explanation: The traditional Indian calendar divides the year into six seasons, each lasting for two months.

Explanation: The regional variations in monsoon climate across India allow for the cultivation of a diverse range of crops, each suited to the specific conditions of different regions.

Explanation: Climate change is likely to cause shifts in agricultural patterns, as changes in temperature and rainfall can affect crop yields and suitability, making some regions more suitable for certain crops while others become less suitable.

Explanation: Current projections suggest that the global temperature will increase by approximately 2 degrees Celsius by the year 2100, leading to various climatic changes.

Explanation: The average annual rainfall in India is approximately 125 cm, although there are significant spatial variations.

Explanation: Climate change can influence the spread of insect-borne diseases like malaria, as warmer temperatures and altered precipitation patterns can create more favorable conditions for disease-carrying insects.

Explanation: Greenhouse gases are components of the atmosphere that trap heat and contribute to the warming of the planet. Carbon dioxide, methane, chlorofluorocarbons, and nitrous oxide are examples of greenhouse gases.

Explanation: The regions along the west coast, including the Western Ghats, as well as the sub-Himalayan areas in the northeast and the Meghalaya hills, receive the highest rainfall in India.
