Question

5 Correct the following sentences
(a) The Earth rotates on the imaginary line called orbit.
(b) The meridians of longitude are full circles.
(c) The parallels of latitude decrease in size from pole to the equator.
(d) The highest possible longitude is 90°.
(e) The length of the equator is about 40,035 km.​

Answer 1

Answer:

(a)The Earth rotates on an imaginary line called an axis,

b)The lengths of all meridians are the same, as all of them are semicircles which connect the two poles. Any two opposite meridians when taken together form a complete circle. The maximum distance between any two meridians is at the Equator.

c)circumference is lengthier at 0°. So equator is lengthiest latitude and the degree increases or move away from equator to pole the circumference of globe decreases hence latitudinal length also decreases. The length of a parallel increases as we move away from the poles towards the equator.

....

d)Lines of latitude (parallels) run east-west around the globe and are used to measure distances NORTH and SOUTH of the equator. Since the equator is 0�, the latitude of the north pole, 1/4 of the way around the globe going in a northerly direction, would be 90�N. This is the highest latitude possible.

e)Using Ve=ReW

1700km/h=20000×W

W=170020000=17200 rotation/hour

Velocity of rotation of pole,

Vp=Rp

Rp=0⇒Vp=0
