1. Answer the questions briefly:
(a) What is Tropic of Cancer?
Ans: The Tropic of Cancer is located at approximately 23.44 degrees north of the Equator. It is the northernmost latitude where the Sun can be directly overhead at noon. This happens during the June solstice, when the Northern Hemisphere is tilted towards the Sun, marking the start of summer in that hemisphere.
(b) Name the three heat zones of the earth.
Ans: The Earth has three heat zones: the Frigid Zone, Temperate Zone, and Torrid Zone. The Torrid Zone, nearest to the equator, is the hottest due to its direct exposure to the Sun’s rays.
(c) What are parallels?
Ans: Lines of latitude, also called parallels, are imaginary lines running east to west that measure distance north or south from the Equator. The Equator, at 0 degrees latitude, is the most well-known parallel and divides the Earth into the Northern and Southern Hemispheres.
(d) What are meridians?
Ans: A meridian is an imaginary north–south line on the Earth’s surface that connects the geographic poles and indicates longitude. For instance, the 40th meridian has a longitude of 40° E or 40° W.
(e) Why is temperature very high in Torrid zones?
Ans: The Torrid Zone, located between the Tropic of Cancer (23.5° N) and the Tropic of Capricorn (23.5° S), receives the most heat from the Sun. In this region, the Sun’s rays are directly overhead at least once a year, leading to the highest temperatures.
(f) In which area of the heat zones is the equator located?
Ans: The Torrid Zone, nearest to the Equator, is characterised by extreme heat and distinct wet and dry phases, rather than the four seasons experienced in temperate regions.
(g) Why is water in frigid zone found in solid state?
Ans: In the Frigid Zone, water turns into ice due to extremely low temperatures. These freezing conditions cause the water to solidify, and as ice forms on the surface, trapped air bubbles become enclosed, reinforcing the solid state of the water.
2. Answer the questions directly:
(a) Within which Hemisphere has the Tropic of Cancer been imagined.
Ans: The Tropic of Cancer is situated in the Northern Hemisphere at approximately 23.5° N latitude. It crosses through North America, Africa, and Asia.
(b) Which imaginary line connects the two poles of the earth?
Ans: Imaginary lines running east-west are known as parallels of latitude, while vertical lines running north-south that connect the two poles are called meridians of longitude.
(c) To which side of the globe is the north pole located?
Ans: The North Pole is located at the centre of the Northern Hemisphere. The nearest land is generally considered to be Kaffeklubben Island, situated off the northern coast of Greenland about 700 km (430 mi) away, though some possibly semi-permanent gravel banks are slightly closer.
(d) What is the latitude of the equator?
Ans: The latitude of the Equator is 0 degrees. It serves as the central reference line for measuring latitude and divides the Earth into the Northern and Southern Hemispheres.
(e) In which hemisphere do you reside?
Ans: India is entirely located in the Northern Hemisphere of the Earth.
3. Tick (✔) the correct answer:
(a) The value of the Prime Meridian
(i) 90°
(ii) 0°
(iii) 66°.
Ans: (ii) 0°
(b) The Frigid zone is located in-
(i) Polar region.
(ii) Equatorial region.
Ans: (i) Polar region.
(c) At what distance from the equator the Tropic of Capricorn is found?
(i) 66º 1/20 S. Lat.
(ii) 23º 1/20 N Lat.
(iii) 23°1/20 S Lat.
Ans: (iii) 23°1/20 S Lat.
(d) At an interval of 1º the total number of meridian will be-
(i) 180 nos.
(ii) 360 nos.
(iii) 90 nos.
Ans: (ii) 360 nos.
4. (a) Name the heat zone extending from north to south immediately from the equator.
Ans: The heat zone extending from north to south immediately from the equator is called the Torrid Zone.
(b) In what form water remains in the sea, where the slanting rays of the sun fall?
Ans: In areas of the sea where the slanting rays of the sun fall, the water primarily remains in a liquid state.
