1. What is a geoid?

1. The Earth cannot be compared with any other geometrical shape as it has a very unique shape.
2. Hence, its shape is called a geoid (earth shaped).

2. What is local time?

1. The time in a particular region or area expressed, with reference to the meridian passing through it. (or)
2. When the sun is overhead on a particular line of longitude, it is 12 noon at all the places located on that line of longitude. This is called local time.

3. How many times would the sun pass overhead a line of longitude?
The sun is overhead on a line of longitude only once a day.

4. What are lines of latitude and longitude?

1. The imaginary lines that run east and west direction on the Earth are called lines or parallels of latitude
2. The imaginary lines drawn vertically connecting the North pole and the south pole are called lines or meridians of longitude.

5. Name the four hemispheres of the Earth.

IX. Give Reasons:

1. The 0° line of longitude is called the Greenwich Meridian.
