Q.21. Where does Torrid Zone lie?
Ans. Torrid zone lies between 231/2°N and 231/2°S.Fig. Torrid zones
Q.22. Name the area between the Tropic of Capricorn and Tropic of Cancer.
Ans. Torrid Zone.
Q.23. Name the true model of the earth.
Q.24. At the poles, the sun rays are ______.
Q.25. What is the importance of Equator?
Ans. The equator is an important reference point to locate places.
Q.26. Define axis of a globe.
Ans. A needle is fixed through a globe in a tilted manner called axis of a globe.
Q.27. Define latitudes.
Ans. The parallel circles from the equator up to the poles are called latitudes.
Q.28. Name the heat zone that receives maximum heat.
Ans. Torrid Zone.
Q.29. Why Frigid Zones are very cold?
Ans. In this zone, the sun does not rise much above the horizon so its rays are always slanting and provides less heat.

Q.35. What does the term 'Grid' mean in Geography?
Ans. The network of the Parallels of Latitude and Meridians of Longitude on the Globe is known as Grid.
Q.36. What is the true shape of the Earth?
Ans. The true shape of Earth is Geoid.
Q.37. Name the different heat zones of the Earth?
Ans. There are mainly three heat zones of the earth:
(i) Torrid zone.
(ii) Temperate zone.
(iii) Frigid zone.
Q.38. Name the two basic points of reference on the Earth’s surface?
Ans. North Pole & South Pole.
Q.39. How can you locate a point on the globe?
Ans. Any point on the globe can be located by knowing its latitudes & longitudes.
Q.40. What is the standard meridian of India?
Ans. The standard meridian of India is 82°30’E.
Q.41. In which zone do the Poles fall?
Ans. Frigid Zone
Q.42. In which unit are the Longitudes measured?
Ans. The distances between Longitude are measured in ‘degrees of longitude.’ Each degree is further divided into minutes, and minutes into seconds.
Q.43. What happens to the Longitudes at the poles?
Ans. Longitudes are semicircles and the distance between them decreases steadily as they move towards the poles until it becomes zero at the poles, where all the meridians meet.
