If anybody know reply ASAP​

Answer 1

Explanation:

The geographic grid refers to the internationally-recognized system of latitude and longitude used to location positions on Earth's surface. Accurate use of this coordinate system is fundamental to the science of geography, which relies so heavily on maps as a medium of communication and analysis.

Answer 2

Answer:

1.A grid is a network of evenly spaced horizontal and vertical lines used to identify locations on a map. For example, you can place a grid that divides a map into a specified number of rows and columns by choosing the reference grid type.

2.Hipparchus, a Greek astronomer (190–120 BC), was the first to specify location using latitude and longitude as co-ordinates. He proposed a zero meridian passing through Rhodes

3.Longitude lines run north-south and mark the position east-west of a point. Therefore, latitude is the angular distance east or west of the Prime Meridian. Lines of longitude run from pole to pole, crossing the equator at right angles

4.Five characteristics of the parallels of latitudes are:

Latitude is the angular distance of a place north or south of the Equator.

There are 180 parallels of latitudes apart from the Equator.

Each parallel of latitude is a circle.

Only the Equator is a Great Circle, all the rest of the latitudes are Small Circles.
