Why do farmers grow some crops in particular areas and not in other areas?
Different crops require different climatic and soil conditions to grow. For example rice require huge amounts of water for growth, cotton can only grow in black soil etc.

Define a map. Can you think of a limitation of maps?
A map is a representation of the Earth or (part of) the surface of the earth that shows countries, rivers, mountains, roads, etc.
Because the Earth is actually 3D, drawing it on a flat surface can lead to a slight distortion of the shape, size, distance, and direction.

the poles

Why is the world divided into time zones?
The world is divided into time zones because different part of earth gets daylight (sunlight) at different times, so to avoid confusion in keeping time over different parts of the country it is divided into time zones.
As Earth rotates on its axis, it moves about 15 degrees every 60 minutes. After 24 hours, it has completed a full rotation of 360 degrees. The scientists used this information to divide the planet into 24 sections or time zones. Each time zone is 15 degrees of longitude wide.

Give some differences between the tools used during the Paleolithic age and the Neolithic age.
Paleolithic Tools - chipped stone, wood and bone tools primarily; blunt, less refined.
Neolithic tools - sharper, polished and refined tools; use of mortar and pestle for grinding

State True or False
The Frigid zone receives the least sunlight because of the revolution of the Earth around the sun.
False
The Frigid Zone receives sun rays that are slanted in nature. This results in the region receiving very little heat from the sun

Determine the local time of Thimpu (Bhutan) located at 90° east longitude when the time at Greenwich (0°) is 12.00 noon
Difference between Greenwich and Thimpu = 90° of longitudes
Total Time difference = 90/15 = 6 hours
Since 90° E is ahead of 0°,
\Local time of Thimpu is 6 hours more than that at Greenwich, i.e. 6.00 p.m.

Assertion(A): Kurnool is a city in Maharashtra which is known for its Paleolithic era cave paintings.
Reason(R): Traces of ash have been found here which suggests people were familiar with the use of fire.
a) Both A and R are true and R is the correct explanation of A.
(b) Both A and R are true but R is not the correct explanation of A.
(c) A is true but R is false.
(d) A is false but R is true
(d) A is false but R is true

Explain why people in the Neolithic period led a sedentary (slow) lifestyle as compared to people in the Paleolithic period.
Due to climate change during the Mesolithic period, in the Neolithic period: -
Human beings began to cultivate their own food and herding animals. People started to stay at one place for a longer period of time to protect the plants and provide them water.
people started to depend primarily on agriculture the amount of grains collected from the harvest increased.
This generated a need to build storage and thus humans started to build huts that were made up of stone, wood, mud and dried grass. They started storing grains and even animals and thus they didn't need to be on the move for their basic needs anymore

Explain how are maps more helpful than a globe.
Globes are only useful if we want to study the earth as a whole.
Maps give detailed information of particular parts of the world.
Maps are also more convenient to carry around than Globes.

San Francisco is approximately 120° west of London (0°). If the time at London is 11:00 a.m, what is the time in San Francisco?
The time difference between London and San francisco: -
120- 0 = 120°
120/ 15 = 8 hours (as 1 hour = 15 degrees)
120° is before 0° so 8 hours minus 11:00 a.m. = 3:00 a.m.

Assertion(A): Hunter-Gatherers used to constantly move from one place to another.
Reason(R): If they stayed at one place they would eventually run out of food and resources so that’s why they had to be on the move regularly.
a) Both A and R are true and R is the correct explanation of A.
(b) Both A and R are true but R is not the correct explanation of A.
(c) A is true but R is false.
(d) A is false but R is true
a) Both A and R are true and R is the correct explanation of A.

What are the uses of symbols on Maps? What are Conventional Symbols?
Symbols represent roads, bridges, trees, railway lines, etc. through certain letters, shades, colours, pictures and lines. In this way, symbols are a convenient means of reading a map.
Maps have a universal language that can be understood by all. There is an international agreement regarding the use of these symbols. These are called conventional symbols.

Explain the concept of Standard Time. What is the meridian used for fixing Indian Standard Time?
The local time of places which are on different meridians are bound to differ. For example, it will be difficult to prepare a time-table for trains which cross several longitudes. In India, for instance, there will be a difference of about 1 hour and 45 minutes in the local times of Dwarka in Gujarat and Dibrugarh in Assam. It is, therefore, necessary to adopt the local time of some central meridian of a country as the standard time for the country. In India, the longitude of 82½° E (82° 30'E) is treated as the standard meridian.

Estimate the time at the following longitudes assuming the Greenwich time as 10 am.
(i) 45 degree East longitude
(ii) 30 degree West longitude
(i) 45/15 = 3 hour difference
East = 10 am + 3 hours = 1 pm
(ii) 30/15 = 2 hour difference
West = 10 am - 2 hours = 8 am
