Your answer is not correct. The correct
answer is 80 mm rainfall received in 30
minutes indicate high intensity of rainfall.
Continue
23
You are right. 80 mm rainfall received in 30
minutes indicate high intensity of rainfall.
Continue
24
Your are right. Soil erosion may result with a
high intensity rainfall like 120 mm of rainfall
in 1 hour.
Continue
25
Your answer is not correct. The correct answer
is Soil erosion may result with a high
intensity rainfall like 120 mm of rainfall in 1
hour.
Continue
26
You are right. Soaking rain like 25 mm of
rainfall a day before will be useful to take up
the sowings.
Continue
27
No please. The correct answer is Water from
high intensity rainfall mostly result in run off
with very little water saturating the soil
profile. So soaking rain like 25 mm of rainfall
a day before will be useful to take up the
sowings.
Continue
28
No please. You are partly correct because the
amount of rainfall received is not clear from the
statement to take up the sowings. The correct
answer is Soaking rain like 25 mm of rainfall a
day before will be useful to take up the sowings.

29
You are right Rains received during June to
September, and October to December are monsoon
rains.
Continue
30
No please. Rain during March to April are not
monsoon rains. These rains are known as summer
showers The correct answer is Rains received
during June to September, and October to December
are monsoon rains.
Continue
31
If you are not sure, the answer is Rains
received during June to September, and October to
December are monsoon rains.

32
You are right This break in rainfall coincides
with pod development in groundnut and thus affect
the pod formation and development.
Continue
33
No please. Please note the break in rainfall.
Rains were received during flowering and
harvesting stages and so, these stages may not be
adversely affected due to moisture
availability. The correct answer is Breaks in
rainfall during late August and early September
coincides with pod development in groundnut, and
thus affect the pod formation and development.
Continue
34
You are right Higher temperatures over land than
sea results in differential heating between land
and sea. Consequent to this, air pressure will be
higher on land compared to the sea. This pressure
gradient brings moisture-laden winds towards land
resulting in monsoon rains.
Continue
35
No please. The correct answer is Higher
temperatures over land than sea results in
differential heating between land and sea.
Consequent to this, air pressure will be higher
on land compared to the sea. This pressure
gradient brings moisture-laden winds towards land
resulting in monsoon rains.

36
You are right Near water body the air will be
saturated with moisture. So, the RH will be quiet
high (gt60) during summer in the coastal areas.
Continue
37
No please. The correct answer is Near water
body the air will be saturated with moisture. So,
the RH will be quiet high (gt60) during summer in
the coastal areas.

barometer (middle Fig.). Hygrometer (bottom
Fig.) is used to measure relative humidity.
Continue
68
You are right Winds move from a high-pressure
system towards a low-pressure system.
Continue
69
No please. The direction of winds between sea
and land depends on the air pressure differences.
If air pressure is higher over the land, then the
winds move towards the sea and vice-versa. The
correct answer is Winds move from a
high-pressure system towards a low-pressure
system.
