Detailed explanation-1: -An equator is an imaginary line around the middle of a planet or other celestial body. It is halfway between the north pole and the south pole, at 0 degrees latitude. An equator divides the planet into a northern hemisphere and a southern hemisphere.

Detailed explanation-2: -We have seasons because Earth’s axis – the imaginary line that goes through the Earth and around which the Earth spins-is tilted. It’s tilted about 23.5 degrees relative to our plane of orbit (the ecliptic) around the Sun.

Detailed explanation-3: -The axis of the Earth is an imaginary line which joins north pole to south pole. It makes an angle of 66.5° with its orbital plane. Q. Rotation is the movement of the Earth around an imaginary axis passing through its poles.

Detailed explanation-4: -The vertical lines running north-south, join the two poles. They are called the meridians of longitude. They are spaced farthest apart at the equator and converge at a point at each pole.

Detailed explanation-5: -The imaginary lines circling the globe in an east-west direction are called the lines of latitude (or parallels, as they are parallel to the equator). They are used to measure distances north and south of the equator. The lines circling the globe in a north-south direction are called lines of longitude (or meridians).
