Violent thunderstorms in the Gangetic plains of India are locally known as Kal Baisakhi.

(v) When the sun is over the Tropic of Capricorn, the climate in Northern Plains is ______
Ans: Winter
When the sun is over the Tropic of Capricorn, the climate in Northern Plains is winter. 

Q2: True or False.

(i) The Cold Weather starts in January._________
Ans: False
The statement "The Cold Weather starts in January" is typically true for many regions in the Northern Hemisphere, especially in temperate and colder climates. In countries located in the Northern Hemisphere, January falls within the winter season, which is generally associated with cold weather due to the tilt of the Earth's axis away from the sun during this time. This leads to shorter days and colder temperatures. However, in regions near the equator or in the Southern Hemisphere, January might not necessarily be considered the cold weather season.

(ii) The Hot Weather season starts from March in South India.___________
Ans: True
The statement "The Hot Weather season starts from March in South India" is true. In South India, the climate is influenced by the Indian Ocean and the monsoon winds. The hot weather season, also known as the pre-monsoon season, typically begins in March as temperatures start to rise in preparation for the upcoming monsoon. This period can bring high temperatures and dry conditions before the monsoon rains arrive.

(iii) The advancing South-West monsoon starts in June.___________
Ans: True
The statement "The advancing South-West monsoon starts in June" is true. The South-West monsoon is a major weather phenomenon in the Indian subcontinent. It is characterized by the seasonal reversal of wind patterns, where moist air from the Indian Ocean moves over the Indian subcontinent, bringing heavy rainfall. The South-West monsoon usually arrives in India in June, marking the beginning of the rainy season. This monsoon is crucial for agriculture and plays a significant role in the Indian economy.

Q3: Tick the correct word.

(i) The Arabian Sea, The Indian Ocean and the Bay of Bengal surround the _________. (the Northern Plains, the Peninsular India, the Western Plains)
Ans: The northern plains
The Bay of Bengal is the northeastern part of the Indian Ocean, bounded on the west and northwest by India.

(ii) The season of a region is affected by________. (The physical features, the people, the cities in that region)
Ans: physical factors
The combination of oceanic and atmospheric circulation drives global climate by redistributing heat and moisture. Areas located near the tropics remain warm and relatively wet throughout the year. In temperate regions, variation in solar input drives seasonal changes.

(iii) In winter season the sun is nearer the ______. (Tropic of Cancer, the Tropic of Capricorn)
Ans: Tropic of Capricorn
When the sun is over the Tropic of Capricorn, the climate in Northern Plains is winter.

(iv) The Northern Mountain Ranges protect India from_______. (Bitterly cold and dry winds of Central Asia, South-West Monsoons)
Ans: Bitterly cold and dry winds of Central Asia
The Himalayas also protect us from the cold winds blowing from the north.

(v) The Tropic of cancer passes through the______ of the country. (Top, Bottom, Middle)
Ans: Middle
Tropic of Cancer is an imaginary line which is at an angle of 23.50 degrees. It is North from the Equator, that passes through the middle of India.

Q4: Define the Following.

(i) Hot Weather Season: The period from March to May (June in North India) characterized by high temperatures and dry conditions. Hot dry winds known as "loo" blow in the Northern Plains during May and June. Pre-monsoon showers occur in West Bengal, Assam, and Kerala, referred to as "Mango Showers" and "Kal Baishakhi" respectively.

(ii) Advancing South-West Monsoon Season: The rainy season occurring from June to September in India. It starts on the Kerala coast in early June and progresses northwards, covering most of the country by mid-July. This period sees a decrease in day temperatures by 5°C to 10°C.

(iii) Retreating South-West Monsoon Season: The months of October and November, during which the South-West monsoon withdraws from India. Fair weather prevails in most regions, and the Tamil Nadu coast receives maximum rainfall during this period.

(iv) Cold Weather Season: Spanning from December to February, this season is characterized by lower temperatures as the sun moves towards the Tropic of Capricorn. January is typically the coldest month, with temperatures averaging around 20°C. The Coromandel Coast experiences some rainfall during this time.

(v) Tropic of Cancer: The circle of latitude located approximately 23.5 degrees north of the equator. It passes through the middle of India and marks the northern limit of the sun's direct rays during the summer solstice.

(vi) Monsoon: A seasonal wind pattern that brings heavy rainfall to certain regions during specific periods of the year. In India, the South-West monsoon brings rain from June to September.

(vii) Physiography: The physical features and landscape characteristics of a region that influence its climate and weather patterns.

(viii) Equator: The imaginary line that circles Earth horizontally and is equidistant from the North Pole and South Pole. It has a latitude of 0 degrees.

(ix) Coromandel Coast: The southeastern coast of India along the Bay of Bengal, known for its tropical climate and occasional rainfall during the Cold Weather season.

(x) Globalization: The process of increased interconnectedness and interdependence among countries, leading to the exchange of culture, goods, services, and ideas on a global scale.

Q5: Match the Following.

Ans: Tropic of Cancer (b): The Tropic of Cancer is an imaginary line located at approximately 23.5°N latitude. It passes through the middle of India and marks the northernmost point where the sun's direct rays fall during the summer solstice.
Advancing Monsoon (a): The advancing South-West monsoon is the rainy season in India, occurring from June to September. It starts on the Kerala coast and gradually covers most of the country by mid-July.
Physiography (d): Physiography refers to the physical features and characteristics of a region, including its landforms, mountains, valleys, and bodies of water. These features influence local weather patterns and contribute to variations in climate.
Retreating Monsoon (e): The retreating South-West monsoon occurs during October and November. During this period, the monsoon winds withdraw from India, leading to fair weather conditions. Tamil Nadu's coast receives maximum rainfall during this period.
Cold Weather Season (c): The Cold Weather season spans from December to February. The sun's position moves towards the Tropic of Capricorn, leading to lower temperatures. The Coromandel Coast experiences some rainfall during this time.

Q6: Answer the Following Questions.

(i) The effects of cold weather on your food.
Ans: The effects of cold weather on your food. -  consuming cold foods sends a shock throughout the body which could lead to other complications like digestive sensitivity, fatigue, and sinus infections.

(ii) The effect of the nearness of a sea on day and night temperatures.
Ans: Sea water gets evaporated due to the heat of the sun and thus water vapour gets mixed in the air. Thus, the air near the sea with higher temperature holds more moisture. As a result, the climate near the sea is humid.

(iii) The effects of hot weather on your clothing.
Ans: Hot weather makes our clothes very warm . So we should wear light cotton clothes during summer.

(iv) The effects of climate on human activities are
Ans: The impacts of climate change include warming temperatures, changes in precipitation, increases in the frequency or intensity of some extreme weather events, and rising sea levels.
