Normally, the temperature decreases with the increase in height from the Earth’s surface, because:

1. The atmosphere can be heated upwards only from the Earth’s surface.

2. There is more moisture in the upper atmosphere.

3. The air is less dense in the upper atmosphere.

Select the correct answer using the codes given below:

(a) 1 only

(b) 2 and 3 only

(d) 1, 2 and 3

Since the atmosphere is warmed from the ground up, and since the air is at its most dense near the surface of the earth, the air near the surface is going to be able to retain much more heat than the air at higher elevations due to the increased amounts of air molecules; higher elevations have fewer air molecules and consequently can’t retain as much heat. The first thing you have to understand is that the earth is NOT heated from direct sunlight. Now, here’s where it all comes together. Since the atmosphere is warmed from the ground up, and since the air is at its most dense near the surface of the earth, the air near the surface is going to be able to retain much more heat than the air at higher elevations due to the increased amounts of air molecules; higher elevations have fewer air molecules and consequently can’t retain as much heat.

Consider the following statements: 1. Size of the sun at dusk 2. Colour of the sun at dawn 3. Moon being visible at dawn 4. Twinkle of stars in the sky 5. Polestar being visible in the sky Which of the above are optical illusions? (a) 1, 2 and 3 (b) 3, 4 and 5 (c) 1, 2 and 4 (d) 2, 3 and 5	c

EXPLANATION:

Option-1( Size of the sun at dusk) is an optical illusion.When the sun (or moon) is high in the sky there are no objects of known size to compare the sun (or moon) to. But when the sun is low in the sky we can see far off objects near the horizon that we know are big and we imagine that the sun is even bigger.The apparent change in size is an optical illusion.Option-2( Colour of the sun at dawn) is an optical illusion.Light is made up of lots of colors. And out of all those colors, red is the one that travels the farthest.That means is that red is the last color seen, when the sun sets. When the sun is setting, all of those colors are slower-moving, and it is no longer bright outside, because the colors are all moving at a separate pace. The other colors start disappearing, and red (being the fastest), is what is last seen.Option-3( Moon being visible at dawn) is NOT an optical illusion.The moon is visible somewhere in the sky at dawn during the entire half of the cycle of phases from Full Moon to just before New Moon.It is not an optical illusion.Option-4( Twinkle of stars in the sky) is an optical illusion.Stars continuously emit light. These light travels through various layers of earth atmosphere before they reach our eyes. Now refractive index decreases as we move from down through atmosphere. So light keeps on getting bent towards normal at each point of incidence. Practically there are infinite points of incidence as refractive index keeps changing as we move down. This happens in accordance and finally light reaches our eye. So we see the star at B but actual position of star is at A. Further atmospheric conditions keeps on changing. Hence light flux reaching our eyes keeps varying and so star appears bright at some time and it appears fade at other. So starts apparently twinkles but practically they don’t.Option-5( Polestar being visible in the sky) is NOT an optical illusion.The sky appears to rotate around points called the celestial poles (one north pole and one south pole). These points represent the directions where the Earth’s rotation axis points.Thus, for a fixed observer on Earth, a celestial pole would always be in the same direction (due north or due south, depending where we are), and its altitude over the horizon would be equal to our latitude.Polaris is not exactly at the celestial pole; it is less than one degree from it (so that it is hard to tell the difference without measuring) making it a good indicator for the pole — that is why it is called the Pole Star.

During a thunderstorm, the thunder in the skies is produced by the Meeting of cumulonimbus clouds in the sky. Lightening that separates the nimbus clouds. Violent upward movement of air and water particles. Select the correct answer using the codes given below. (a) 1 only (b) 2 and 3 (c) 1 and 3 (d) None of the above produces the thunder	d

Thunder is the sound caused by lightning. The sudden increase in pressure and temperature from lightning produces rapid expansion of the air surrounding and within a bolt of lightning. In turn, this expansion of air creates a sonic shock wave, similar to a sonic boom, which produces the sound of thunder The cause of thunder has been the subject of centuries of speculation and scientific inquiry. The first recorded theory is attributed to the Greek philosopher Aristotle in the third century BC, and an early speculation was that it was caused by the collision of clouds. Subsequently, numerous other theories were proposed. By the mid-19th century, the accepted theory was that lightning produced a vacuum. In the 20th century a consensus evolved that thunder must begin with a shock wave in the air due to the sudden thermal expansion of the plasma in the lightning channel.

(km.) north of the equator the winds are much weaker, in comparison.
The stronger winds to the south pile up water where the winds are weak. As a result, the surface of the ocean can be up to 6 in. (15 cm.) higher and the thermocline (region of strongest decrease of temperature with increasing depth) as much as 328 ft. (100 m.) deeper than it is directly to the north. The excess water flows eastward under the influence of the Earth’s rotation, giving rise to the equatorial countercurrents.

Standard NCERT question! In the diagram, west of the line falls in Gujarat, while the east falls in Arunachal Pradesh.

55. In the South Atlantic and South Eastern Pacific regions in tropical latitudes, cyclone does not originate. What is the reason?
a) Sea Surface temperature are low
b) Inter Tropical Convergence Zone seldom occurs
c) Coriolis force is too weak
d) Absence of land in those regions
Solution: a)

Option C is wrong. Coriolis force is weak only in the region around 0-5 degrees North or South latitudes.
Option B is also wrong. ITCZ formation is not essential to the formation of cyclones. Cyclones are formed in regions where ITCZ does not form, for e.g. in North Atlantic.
Option D is absurd as absence of land boosts cyclones. Presence of land cuts off moisture from the cyclone. So, the most appropriate answer should be A.
For cyclone formation, a sea temperature of at least 26 degree Celsius is needed. In the South-eastern pacific and South Atlantic region cold currents are found. This leads to lower sea temperatures. Hence, cyclones don’t form there.

“Each day is more or less the same, the morning is clear and bright with a sea breeze; as the sun climbs high in the sky, heat mounts up, dark clouds form, than rain comes with thunder and lightning. But rain is soon over.”
Which of the following regions is described in the above passage?

3. Mizoram
In which of the following states do “Tropical Wet Evergreen Forests” occur?
a) 1 only
b) 2 and 3 only
c) 1 and 3 only
d) 1, 2 and 3
Solution: c)

These are typical rain forests which grow in those areas where the annual rainfall exceeds 250 cm, the annual temperature is about 25°-27°C the average annual humidity exceeds 77 per cent and the dry season is distinctly short.
The true evergreen forests are found along the western side of the Western Ghats (between 500 to 1370 metres above sea level) south of Mumbai, in a strip running from northeast to south-west direction across Arunachal Pradesh, Upper Assam, Nagaland, Manipur, Mizoram and Tripura upto a height of 1070 metres and in the Andaman and Nicobar Islands.

. In which of the following activities are Indian Remote Sensing (IRS) satellites used?

Select the correct answer using the code given below
a) 1, 2 and 3 only
b) 4 and 5 only
c) 1 and 2 only
d) 1, 2, 3, 4 and 5
Solution: a)

For telecommunications geo-stationary satellites are used. Hence, you can easily eliminate statement 4, which then also eliminates statement 5 (because both occur together).
Under remote sensing, Hyperspectral imaging produces an image where each pixel has full spectral information with imaging narrow spectral bands over a contiguous spectral range. Hyperspectral imagers are used in various applications including mineralogy, biology, defence, and environmental measurements.
So, the only possible answer can be A.

Tides occur in oceans and seas due to which of the following?
1. Gravitational Force of the Sun
2. Gravitational Force of the Moon
3. Gravitational Force of the Earth

Select the correct answer using the code given below
a) 1 only
b) 2 and 3 only
c) 1 and 3 only
d) 1, 2, and 3
Solution: d)

Tides are the rise and fall of sea levels caused by the combined effects of gravitational forces exerted by the Moon, Sun, and rotation of the Earth.

The times and amplitude of tides at a locale are influenced by the alignment of the Sun and Moon, by the pattern of tides in the deep ocean, by the amphidromic systems of the oceans, and the shape of the coastline and near-shore bathymetry.

Consider the following statements

1. The winds which blow between 30 degrees N and 60 degrees S latitudes throughout the year are known as westerlies.
2. The moist air masses that cause winter rams in North-Western region of India are part of westerlies.
Which of the statements given above is/are correct?
(a) 1 only
(b) 2 only
(c) Both 1 and 2
(d) Neither 1 nor 2
Solution: b)

Westerlies flow between latitudes 30-60 degrees North and 30-60 degrees South. The statement mentions 30N-60S. So it is wrong.
The western cyclonic disturbances are weather phenomena of the winter months brought in by the westerly flow from the Mediterranean region. They usually influence the weather of the north and north-western regions of India. They are a non-monsoonal precipitation pattern driven by the Westerlies.

In India the steel production industry requires the import of
a) saltpeter
b) rock phosphate
c) coking coal
d) All of the above
Solution: c)

Saltpetre (Potassium nitrate) is not used in the production of steel. It is instead used in fertilizers, tree stump removal, rocket propellants and fireworks. It is one of the major constituents of gunpowder (blackpowder) and has been used since the Middle Ages as a food preservative.
India definitely imports coking coal. So, the answer has to be C.
It requires 0.8 tonnes coking coal to produce one tonne of steel. The government had recently imposed a 2.5 per cent duty on coking coal import.

Which of the statements given above is/are correct?

(a)1 and 3 only

(b)2 only

(d)1, 2 and 3

ANS:B

Statement 1 is not correct. The Teesta River originates from the Pahunri (or Teesta Kangse) glacier and flows southward through the Sikkim Himalaya. where the Rangpo River joins, and where it forms the border between Sikkim and West Bengal up to Teesta Bazaar. Just before the Teesta Bridge, where the roads from Kalimpong and Darjeeling join, the river is met by its main tributary, the Rangeet River. Hence Statement 2 is correct.

It changes course southwards flowing into West Bengal. The river then goes merging up with the Brahmaputra River after it bifurcates the city of Jalpaiguri and flows just touching Cooch Behar district at Mekhliganj and moves to Fulchori in Bangladesh. Thus it does not flow directly into the Bay of Bengal. Hence statement 3 is not correct.

Which of the following is/are the possible consequence/s of heavy sand mining in river beds?

Decreased salinity in the river
Pollution of groundwater
Lowering of the water-table

Select the correct answer using the code given below:

(a)1 only

(b)2 and 3 only

(d)1, 2 and 3

ANS:B

Excessive instream sand-and-gravel mining causes the degradation of rivers. Instream mining lowers the stream bottom, which may lead to bank erosion. Depletion of sand in the streambed and along coastal areas causes the deepening of rivers and estuaries, and the enlargement of river mouths and coastal inlets. It may also lead to saline-water intrusion from the nearby sea. The effect of mining is compounded by the effect of sea level rise. Any volume of sand exported from streambeds and coastal areas is a loss to the system.

Excessive instream sand mining is a threat to bridges, river banks and nearby structures. Sand mining also affects the adjoining groundwater system and the uses that local people make of the river. Sand aquifer helps in recharging the water table and sand mining causes sinking of water tables in the nearby areas, drops leaving the drinking water wells on the embankments of these rivers dry. Turbidity increases at the mining site.
