Question

How will the rays fall between-1. 0° and 23°30' North and South?2. 23°30' and 66°30' North and South?3. 66°30' and 90° North and South?

Answer 1

1. The regions between 0° and 23°30' North and South are called tropic of cancer and tropic of Capricorn respectively. The sunrays fall directly in on these regions and they receive the maximum heat.

2. The regions between 23°30' and 66°30' North and South which are called north temperate zone and south temperate zone respectively. The sun never shines overhead in these regions. These areas have moderate temperature.

3. At 90° North and South, this means that at North Pole and South Pole respectively, the sun does not rise above the horizon and sunrays fall in slanting position. Therefore, these regions are always cold.

Answer 2

Latitude

Latitude indicates the location of a place on Earth north or south of the Equator. Latitude is an angular measurement in degrees (marked with °) ranging from 0° at the Equator to 90° at the poles (90° N for theNorth Pole or 90° S for the South Pole).

Degrees of latitude are parallel so the distance between each degree remains almost constant. Each degree of latitude is approximately 69 miles (111 kilometers) apart. The distance varies (due to the earth's slightly ellipsoid shape) from 68.703 miles (110.567 km) at the equator to 69.407 (111.699 km) at the poles. This is convenient because each minute of latitude (1/60th of a degree) is approximately one mile.
