Question

Into how many temperature zones the earth can be divided?
A.Two
B.Three
C.Four
D.Five

Answer 1

Hint:Creation of heat zones is caused due to rotation of earth on its axis together with revolution around the sun.The spherical shape of the earth along with its movements around the sun causes the difference in the angles at which the sun's rays fall on the earth's surface. This causes a difference in the distribution of heat on the earth's surface.

Complete answer:
 Creation of heat zones: The difference in the angles at which the sun's rays fall on the earth's surface are due to the spherical shape of the earth as well as its movements around the sun . This causes a difference in the distribution of heat on the earth's surface. As a result the world has been divided into three distinct heat or temperature zones.
A.The Torrid Zone: This zone stretches between twenty three and half degree N and S latitudes and more or less receives the vertical rays of the sun. A moderately warm climate throughout the year is experienced by this region.
B. The Temperate Zone: In between the Torrid and the Frigid zones i.e., between twenty three and half degree North and South and sixty six and half North and South lies the Temperate Zone. In this zone the sun's rays fall obliquely and hence the region experiences a moderate climate.

Hence, the correct answer is option (B).

Note:The last and third zone is Frigid Zone. The Frigid Zone: This zone extends from sixty six and half N to ninety N (or North Pole) and sixty six and half S to ninety S (or the South Pole). Since the sun's rays fall extremely obliquely in this region, the region experiences extremely cold climates.
