Precipitation Exercise question Solutions :
Question no – (1)
Answer :
(a) It is the main source of the water that you use. Sometimes it is torrential and sometimes continuous. Most of the agriculture in India is dependent on it.
= Rainfall.
(b) It seems as if water droplets are floating in the atmosphere. In London, one cannot see the Sun till the afternoon during winters because of this phenomenon.
= Fog.
(c) It never precipitates like this in equatorial areas. Precipitation in the solid form sometimes causes damage to the crops.
= Frost.
(d) A white cotton like layer spreads on the earth’s surface. Because of this form of precipitation, the State of Jammu and Kashmir has to change its capital in winters. In Maharashtra, it does not precipitate like this.
= Snowfall.
Question no – (4)
Answer :
(a) Here the odd one is – Acid rain.
(b) Here the odd one is – Dew.
(c) Here the odd one is – Measuring jar.
Question no – (5)
(1) In what ways does precipitation occur on the earth?
Answer :
Due to the condensation of water vapour in the atmosphere, precipitation occur on the earth.
(2) Comment on the rainfall occuring in the rain shadow area.
Answer :
The rain shadow area of a mountain is the opposite side of the windward side. The rain shadow area of the mountains receives less rainfall because most of the rainfall happens on the windward side.
(3) Which type of rainfall occurs in most of the world? Why?
Answer :
Orographic rainfall occurs in most of the world. Winds coming from lakes or seas are moisture-laden. They are obstructed by the high mountain ranges coming in their way. They start going upwards along the slope of the mountains, The temperature of these winds drop and condensation occurs and rainfall takes place. Thus because of the obstruction of the mountains, this type of rainfall occurs in most of the world.
(4) If condensation occurs closer to the earth’s surface, what types of forms become visible?
Answer :
If condensation occurs closer to the earth’s surface fog, dew or frost become visible.
Question no – (6)
Answer :
(1) Difference between the Dew and Frost are –
- Dew :
(i) When moisture-laden air near the earth’s surface comes into contact with very cold objects, condensation of the vapour takes place. They turn into very small water droplets. These water droplets stick to the surface of the cold objects. This is called dew.
(ii) Dew is basically the particles of water in liquid form.
- Frost :
(i) If the temperature of the air is less than 0°C, the water droplets stuck to the surfaces of cold objects freeze. This frozen water droplet is called frost.
(ii) Frost is the water particles which is in frozen form.
