Answer: B. It is useful for navigation.
Explanation:
The Mercator is a famous map projections that was created by Geradus Mercator who was a Flemish geographer in 1569.
The Mercator is used for nautical purposes and is regarded as the standard map projection due to the fact that the lines of true direction can be represented on it and hence useful for navigation.

Answer:
Option (C)
Explanation:
A scale is usually defined as the ratio between the distance between two particular places on the map and the actual distance between the two places on the actual ground surface.
It is widely used by the geographers while studying a map, in order to explain the relationship between the map distance and the earth's distance. This scale is mentioned in the map, mostly at the bottom of the map.
For example, a map scale of 1:500000, this means that 1 centimeter on the map is equivalent to 5000 meters = 5 kilometers on the ground surface.
Thus, the correct answer is option (C).
Answer:
D. Solar radiation heats the asphalt; the air immediately above is heated through conduction; the warm air rises in free convection.
Explanation:
As the parking lot is exposed to the sun, on a sunny afternoon, we can consider that the sun is radiating with high intensity in this environment, causing the asphalt to be strongly heated. In this case, the air that comes in contact with the asphalt ends up being heated, because the heat of the asphalt is transmitted by the air through the process called conduction, which is the heat transmitted by the agitation of the molecules.
The heated air becomes less dense, that is, it becomes lighter and this causes it to rise, while the cold air is more dense and descends, coming into contact with hot asphalt and also heating up. In that case, a heat transfer called convection occurred.
This means that light from one star takes 100 earth years to travel to the other.
