Set-5 Flashcards
Quantity of fresh air required for a man is 1000 cubic feet of air for every____________?
0
A. 5 minutes
B. 10 minutes
C. 15 minutes
D. 20 minutes
D. 20 minutes
What kind of weathering takes place on the valley side above the surface of the glacier?
0
A. Plucking
B. Abrasion
C. Chemical weathering
D. Frost shattering
D. Frost shattering
Frost shattering is a type of physical weathering that occurs when water freezes and expands in cracks in rocks. The expansion of the ice puts pressure on the rock, which can cause it to break apart. Frost shattering is most common in cold climates where there is a lot of freezing and thawing.
Rainfall related to mountains is:
0
A. Orographic rainfall
B. Normal rainfall
C. Monsoon rains
D. Cyclonic rainfall
A. Orographic rainfall
Rainfall related to mountains is called orographic rainfall. It occurs when moist air is forced to rise over a mountain range. As the air rises, it cools and condenses, forming clouds. The clouds eventually release their moisture as rain or snow.
What is meant by “Equinox”?
0
A. The longest day
B. The shortest day
C. The sun-month long day
D. Equal duration of day and night
D. Equal duration of day and night
The distance of longitude represents how many minutes difference in time?
0
A. 10 minutes
B. 4 minutes
C. 15 minutes
D. 1 minute
B. 4 minutes

1
A. Moon is revolving round the earth
B. Earth is revolving round its axis
C. Earth is revolving round the sun

0
A. 1932
B. 1940
C. 1930
D. 1928
A. 1932
The oldest barrage on the river Indus at Sukkur was built in 1932. It is a barrage on the Indus River near the city of Sukkur in the Sindh province of Pakistan. The barrage was built during the British Raj from 1923 to 1932 and was named Lloyd Barrage.
The Head Works and Canals were completed by 1932. On its completion it was opened by The 1st Earl of Willingdon, Viceroy of India. The scheme had been launched by the Governor of Bombay, Sir George Lloyd (later known as Lord Lloyd), and it was named in his honour
Afternoon rains in the equatorial region are the result of influences _______?
0
A. Land Breeze
B. Monsoon
C. Frontal
D. Convectional
D. Convectional
Convection is the process of heat transfer by the movement of fluids. In the atmosphere, convection is responsible for the formation of clouds and precipitation.
The sun’s heat warms the Earth’s surface, and the warm air rises. As it rises, it cools and condenses, forming clouds. The clouds eventually release their moisture as rain or snow.
Convection is most common in the equatorial region, where the sun’s heat is strongest. The warm, moist air rises and condenses, forming clouds that produce afternoon rains.
When a warm air is lifted off the surface in temperature depression it is called ________?
0
A. An occlusion
B. A cold front
C. An anticyclone
D. A warm front
A. An occlusion
a process by which the cold front of a rotating low-pressure system catches up the warm front, so that the warm air between them is forced upwards off the earth’s surface between wedges of cold air.
Water vapour turns into clouds in the atmosphere when:
0
A. It rains
B. The temperature rise
C. Dew point is reached
D. Evaporation takes place
C. Dew point is reached
Weather describe the condition of ______ at any one time.
0
A. The earth
B. The land surface
C. The atmosphere
D. The ionosphere
C. The atmosphere

0
A. Wet bulb thermometer
B. Maximum thermometer
C. Ordinary thermometer
D. Anemometer
D. Anemometer
A wind which reverses seasonally is known as_____?
0
A. Trade
B. Cyclonic
C. Monsoon
D. Polar
C. Monsoon
A canyon is a large form of ________?
0
A. Dry valley
B. Gorge

Which of the statements to about the Troposphere is not true?
0
A. It contains 85-90% of the atmosphere’s mass
B. It contains nearly all the water and oxygen of the atmosphere
C. It is the zone which exhibits changes in condition of weather
D. It is about 350 km thick
D. It is about 350 km thick
The final phase of a star’s evolution is determined by the star’s:
0
A. Age
B. Gravitational pull
C. Density
D. Mass
D. Mass
Which of these is not a Metamorphic rock?
18
A. Quartzite B. Slate C. Gneiss D. Schist E. Diorite
E. Diorite ✓
Diorite is an igneous rock, which means it is formed when molten rock (magma or lava) cools and solidifies. Metamorphic rocks, on the other hand, are formed when existing rocks are subjected to heat and pressure. This can cause the rocks to change their mineral composition, texture, and structure.
Bore is caused by______?
0
A. Rising tide while meeting river currents
B. Friction from prevailing winds
C. Spring tide and strong winds
D. Unequal heating of oceans
A. Rising tide while meeting river currents
The strength of wave action depends on all these EXCEPT:
0
A. Currents in the sea
B. Wind strength
C. Depth of coastal water
D. Height of waves
A. Currents in the sea
The areas around the North and South poles within the Polar circles is called _____________?
0
A. The Torrid Zone
B. The Frigid Zone
C. The Temperature Zone
D. The Hardiness Zone
B. The Frigid Zone

0
A. 27.5%
B. 20.3%
C. 14.5%
D. 8.23%
D. 8.23%
