What Are the Four Cardinal Directions?

Question 1:

All Children Are Playing in Front of the Building. According to Kid-1, the School Building Is Behind Him, and According to Kid-2, the School Building Is in Front of Him. How Is It Possible?

Answer:

• The direction of an object changes with respect to the position of a person.
• Kids 1 and 2 must be standing opposite one another which changes the direction of the school for them.

Question 2:

Why Is India Situated Towards the East of Africa and the West of Thailand?

Answer:

• The north, south, east and west directions are related to your position on the Earth.
• When one is facing north, the east is towards their right side and the west is towards their left side.
• The position of India is such that Africa is on India’s left (west) side and Thailand is on India’s right (east) side.
• So, with respect to Africa, India is in the east direction, and for Thailand, India is in the west.

About Maps

Question 1:

Why Does the North Direction Always Lies on Top of the Map?

Answer:

• European explorers drew the first-ever maps. European countries are situated in the northern hemisphere of the Earth.
• For their convenience, they made maps pointing to the north on the top, as they mostly explored the northern hemisphere.
• Later it was standardized and accepted worldwide.

Question 2:

Why Is the Scale So Important for Map Reading?

Answer:

• A map without a scale is a mere sketch of that area.
• An appropriate scale tells you about the real distance between two locations on the map.
• It also helps to measure the area of a particular place.
• So, a map without the correct scale will not be useful.

Question 3:

Satellite Images Are More Reliable Than Human Explorations for Map-Making. Why So?

Answer:

• A satellite takes pictures of an area from space.
• >These images are taken from the top, so they give the correct idea about the size of the buildings, directions of roads, and other things about an area.

Question 4:

How to Find Location by Latitude and Longitude?

Answer:

• Latitudes and longitudes are imaginary horizontal and vertical lines that make a grid around the globe.
• These intersect at a unique point which is not the same for any place.
• Hence, the position of latitudes and longitudes can be used to specify the absolute location of a place on Earth’s surface.

Question 5:

A Map Can Go Out of Date. Explain How.

Answer:

• A map is a symbolic representation of an area at a particular time.
• Old maps show the locations of the prominent features of that time.
• These features may change in the future. For example, a river’s flow can change over a certain period. The political boundaries of a city, state, or country may change.
• Therefore, a map can go out of date.
