1. Answer the following questions briefly:
(a) What is the true shape of the earth?
(b) What is the globe?
(c) What is the latitudinal value of the Tropic of Cancer?
(d) What are the three heat zones of the Earth?
(e) What are parallels of latitude and meridians of longitude?
(f) Why does the Torrid Zone receive the maximum amount of heat?
(g) Why is it 5.30 p.m in India when it is 12.00 noon in London?
(a) What is the true shape of the earth?
The Earth is shaped like a slightly flattened ball. It’s mostly round but a bit squished at the poles and bulging at the equator.
(b) What is the globe?
A globe is a spherical model of the Earth. It represents the Earth’s surface, including its continents and oceans, in miniature form. It’s a useful tool for understanding geography and visualizing the Earth’s features.
(c) What is the latitudinal value of the Tropic of Cancer?
The latitudinal value of the Tropic of Cancer is approximately 23.5 degrees north of the equator.
(d) What are the three heat zones of the Earth?
The three heat zones of the Earth are:
- Torrid Zone (Tropical Zone): The area between the Tropic of Cancer and the Tropic of Capricorn, known for its consistently warm temperatures.
- Temperate Zone: The area between the Tropic of Cancer and the Arctic Circle in the Northern Hemisphere, and between the Tropic of Capricorn and the Antarctic Circle in the Southern Hemisphere, characterized by moderate temperatures.
- Frigid Zone: The area within the Arctic Circle in the Northern Hemisphere and the Antarctic Circle in the Southern Hemisphere, known for its cold temperatures.
(e) What are the parallels of latitude and meridians of longitude?
Parallels of latitude are imaginary lines that run parallel to the equator, marking distances north and south of the equator. They help in locating places on the Earth’s surface in terms of their north-south position.
Meridians of longitude are imaginary lines that run from the North Pole to the South Pole, passing through both poles. They help in locating places on the Earth’s surface in terms of their east-west position.
(f) Why does the Torrid Zone receive the maximum amount of heat?
The Torrid Zone receives the maximum amount of heat because it is located near the equator, where the Sun’s rays are most direct throughout the year. This region receives more sunlight per unit area compared to other parts of the Earth, resulting in higher temperatures. Additionally, the Torrid Zone has a smaller area for the Sun’s energy to spread over, further contributing to its warmth.
(g) Why is it 5.30 p.m in India when it is 12.00 noon in London?
It’s 5:30 p.m. in India when it’s 12:00 noon in London because India is located to the east of London, which means it is ahead in terms of time zones. As the Earth rotates from west to east, places located to the east experience time ahead of places to the west. India is approximately 5 hours and 30 minutes ahead of London in terms of time difference.
