Question 3(a)

Why is a map more useful than a globe? Give reasons for your answer.

Answer

Map is more useful than a globe because:

1. A map is more accurate than a globe and provides more precise information as maps are drawn to scale whereas a globe is not drawn to scale.
2. A globe represents the relative shapes and sizes of the continents, countries and oceans of the entire earth in 3D whereas maps can be of different types like Large Scale maps, Small scale maps, Physical Maps, Political Maps, Thematic maps, etc. helping us to accurately find location of a country, distance, direction and distribution of crops, etc.
3. All details of a place cannot be shown on globe while it can be easily shown on a map.

Question 3(b)

What is the significance of colour in map reading?

Answer

The colours in the map help us to identify the features of that place easily. As these colours are universally accepted, hence they do not cause any confusion to the map reader. For example, blue colour is used to show water bodies, red colour is used to denote settlements and so on.

Question 3(c)

Question 3(d)

What do you mean by water cycle? Explain with the help of a neat diagram.

Answer

The continuous interchange of water between the oceans, atmosphere and land is called Hydrological cycle or Water cycle. It connects all the three realms of the earth: lithosphere, hydrosphere and atmosphere.

The differential heating of the earth by the sun causes water to evaporate. The atmospheric blanket around the earth does not allow water vapour to escape. When the water vapour comes in contact with the cooler layers of atmosphere, it condenses to form clouds and falls back on the earth in the form of rain, snow or hail. This water flows into rivers or goes underground or back into the oceans. This circulation of water in different forms is called water cycle.

Question 3(e)

What is subsistence farming? State two features of this type of farming.

2. Any surplus crop could be exchanged for goods or stored for future use in times of poor harvest.

Question 5

Give reasons for the following:

(a) Southern ocean is not navigable.

(b) Young fold mountains have high peaks.

(c) Rift Valley has steep sides.

Answer

(a) Southern Ocean is not navigable because it remains frozen for the most part of the year.

(b) Young fold mountains have high and pointed peaks because they are younger and have not been much eroded by wind or water. On the contrary, old fold mountains have been subjected to the forces of denudation (such as weather, rivers, glaciers) for a longer geological period. Due to this prolonged erosion, they are lower in height and have round peaks.

(c) Rift valley have steep sides because they are formed as a linear depression or trough by the sinking of the intermediate crustal rocks between two or more parallel faults. Sudden rifting of tectonic plates leads to steep sides of Rift valley.
