Explanation
The Tropic of Cancer is an important imaginary line that passes through the middle of India. It is located at approximately 23.5 degrees north of the equator. This line marks the northernmost point where the sun appears directly overhead at noon on the summer solstice. It divides the Earth into the Northern Hemisphere and the Southern Hemisphere, and its position has significant implications for climate and weather patterns in the region.

Explanation
Area-wise, India is the seventh-largest country in the world. It has a total land area of approximately 3,287,263 square kilometers (1,269,219 square miles). The countries with larger land areas than India are Russia, Canada, China, the United States, Brazil, and Australia. Despite being the seventh-largest country in terms of land area, India has a very high population density, making it one of the most densely populated countries in the world.

Explanation
The Lakshadweep Islands are located in the Arabian Sea. They are a group of 36 coral islands off India's southwestern coast, forming a Union Territory of India. The islands are known for their lush green landscapes, beautiful lagoons, and diverse marine life. The Andaman and Nicobar Islands, on the other hand, are located in the Bay of Bengal, east of the Indian mainland. They also form a Union Territory of India and are known for their rich biodiversity, tropical rainforests, and indigenous tribes.

Explanation
The Arabian Sea is the large water body located in the west of India. It is a region of the northeastern Indian Ocean bounded on the north by Pakistan and Iran, on the west by the Arabian Peninsula, and on the east by India. It is an important body of water for India as it provides access to international trade routes and serves as a vital fishing ground.

Explanation
India lies to the north of the equator. It is situated entirely in the Northern Hemisphere, with its mainland extending between 8°4'N and 37°6'N latitudes. India is also the seventh-largest country in terms of land area and the second-most populous country in the world. Its location in the Northern Hemisphere influences the country's climate, with a wide range of weather patterns across its diverse landscape, from the Himalayan mountains in the north to the coastal regions in the south.

Explanation
The given statement is false because the population of India is not 150 crores. As of the latest data from 2023, the population of India is estimated to be around 1.39 billion, which is equivalent to 139 crores.

Explanation
False. India is not surrounded by water bodies on all four sides. India is located in South Asia and is bordered by several countries on its northern, western, and eastern sides. These countries include Pakistan to the west, China, Nepal, and Bhutan to the north, and Bangladesh and Myanmar to the east. India is surrounded by water bodies on its southern and southwestern sides, with the Bay of Bengal to the east and the Arabian Sea to the west. These water bodies form part of the Indian Ocean and provide India with important maritime trade routes and access to international waters. Despite not being surrounded by water on all four sides, India's extensive coastline of over 7,500 kilometers (4,671 miles) makes it an important player in regional maritime affairs.

Explanation
False. The Indian Ocean is not located to the west of India. The Indian Ocean is a vast body of water that surrounds the Indian subcontinent, but it is primarily located to the south and east of India. The Arabian Sea, which is a part of the Indian Ocean, is located to the west of India. The Indian Ocean covers an area of about 70,560,000 square kilometers (27,240,000 square miles) and is the world's third-largest ocean. It is bounded by Asia to the north, Africa to the west, and Australia to the east. The Indian Ocean plays a significant role in India's climate, economy, and strategic interests, with important shipping lanes, fishing grounds, and natural resources.

Explanation
True. Pakistan is located to the west of India. The two countries share a border that stretches for about 2,900 kilometers (1,800 miles) from the Himalayan region in the north to the Arabian Sea in the south. The border between India and Pakistan is known as the Radcliffe Line, named after Sir Cyril Radcliffe, who chaired the boundary commissions that divided British India into India and Pakistan in 1947. The border has been a source of conflict between the two countries, with several wars and skirmishes fought over the disputed territory of Kashmir. Despite the tensions, the two countries share cultural, historical, and economic ties, and there have been efforts to improve bilateral relations and promote peace in the region.

Explanation
India is bounded in the north by the Himalayas. The Himalayas is a mountain range that stretches across several countries, including India. It is the highest mountain range in the world and acts as a natural barrier, separating India from the rest of Asia. The Himalayas have a significant impact on India's climate, culture, and biodiversity. Many rivers, including the Ganges, originate from the Himalayas, making it a vital water source for India.

Explanation
The Indian Ocean is named after our country. This is because the ocean is located primarily in the region surrounding the Indian subcontinent. It is bounded by Africa to the west, Asia to the north, Australia to the east, and the Southern Ocean to the south. The name "Indian Ocean" reflects its close proximity to India and the influence of the Indian subcontinent on the surrounding region.
