What percentage of incoming solar radiation is able to reach the earth?

  1. $5$%

  2. $10$%

  3. $51$%

  4. $65$%


Correct Option: C

The solar radiation reaches the earth in the form of ____________.

  1. short waves

  2. medium waves

  3. long waves

  4. none of the above


Correct Option: A
Explanation:

Our sun is the main source of energy and heat. It provides solar energy or fuel for the process of weather and climate. The energy emitted by the sun is known as solar radiation. The incoming radiation to the earth is known as isolation and it reaches in the earth in form of short waves.

The moderating influence decreases and the people experience extreme weather conditions because of __________.

  1. Pressure and wind

  2. Altitudes

  3. Latitudes

  4. Increasing distance from the sea


Correct Option: D
Explanation:

The moderating influence decreases and the people experience extreme weather conditions because of increasing distance from the sea. Places which are located on coastal region experience moderate climate as they are affected by land and sea breezes. They are neither too hot nor too cold, e.g. Mumbai, Chennai. Places which are located away from the sea have an extreme climate. They are too hot in summer and too cold in winter, e.g. Delhi, Bhopal.

One of the factors influencing climate of any place is ___________.

  1. Human beings

  2. Ocean currents

  3. Moon

  4. None of these


Correct Option: B
Explanation:

The generalization of the atmospheric condition over a long period of time is referred to as climate. It is the long-term pattern of weather in a particular area. Following are the factors which influence the climate of any place:

  1. Distance from equator - Places located near equator have hotter climate as compared to the places located away from equator as they receive direct sun rays.
  2. Altitude - Places located on high altitude have cooler climate as compared to the places located on plains.
  3. Prevailing winds - Places which experiences on-shore winds have high rainfall as compared to the places experiencing off-shore winds.
  4. Ocean currents - Winds which blow over warm currents brings more rainfall as compared to the winds blowing over cold currents.
  5. Distance from sea - Areas located near sea experiences moderate climate, whereas areas located away from sea experiences extreme climate.

Temperature decreases and atmosphere becomes less dense with increasing ____________.

  1. Distance from the sea

  2. Ocean currents

  3. Altitude

  4. Latitude


Correct Option: C
Explanation:

With increasing altitude the the temperature decreases and atmosphere becomes less dence. The direct source of atmospheric heat lies at the surface of the earth,the higher we ascend in the atmosphere,the lower the temperature are.The lower layers of the air at or near the surface are dence cause it contains more water vapour,more water particles and more dust particles than the upper air.Since these substances absorb a large amount of terrestrial radiation,the lower part of the atmosphere has higher temperature and dence than upper part of the atmosphere.

The range of temperature of Delhi in comparison of Kolkata is _________.

  1. extreme

  2. Too little

  3. Zero

  4. Uniform


Correct Option: A
Explanation:
  • Delhi is located in the interior of the continent far away from sea thus it experiences extremes of temperature viz high heat in summer and: very cold in winter. Range of temperature 2 degrees to 45 degrees Celsius approximately.
  • Kolkata is nearer to the sea thus experiences moderate changes in temperature from summer to winter thus Delhi is comparative extreme with respect to the range of temperature.

Temperature varies from place to place with latitude and altitude. It may increase or decrease depending upon the factors that affect temperature. Certain anomalies may also develop on account of unique combination of factors. The inversion of temperature would mean that the _________.

  1. Temperature decreases with elevation

  2. Temperature is constant at different elevations

  3. Temperature decreases and then increases with elevation

  4. Temperature changes along the same latitude


Correct Option: C
Explanation:
  • Normally when we move up the altitude the temperature decreases with a certain rate called the normal lapse rate.
  •  However, sometimes there is inversion or change in this property and the temperature after a certain height starts to increase rather than decreasing. This is called inversion of temperature, thus option C is correct. 

The temperature generally tends to decrease towards the poles because ________________________.

  1. the air movement is generally towards the equator

  2. the polar winds are cool

  3. the earth's shape at poles

  4. the solar rays fall slanting on poles


Correct Option: D

The sun's energy is dissipated and scattered before it reaches the ______.

  1. mars

  2. pluto

  3. moon

  4. earth


Correct Option: D
Explanation:

Earth,

Once the sun's energy reaches earth, it is intercepted first by the atmosphere. A small part of the sun's energy is directly absorbed, particularly by certain gases such as ozone and water vapor. Some of the sun's energy is reflected back to space by clouds and the earth's surface.

Most of the particles of solar wind are charged ________.

  1. electrons

  2. neutrons

  3. protons

  4. mesons


Correct Option: A
Explanation:

Electrons

The solar wind is a stream of charged particles released from the upper atmosphere of the Sun, called the corona. This plasma consists of mostly electrons, protons and alpha particles with kinetic energy between 0.5 and 10 keV. Embedded within the solar-wind plasma is the interplanetary magnetic field.
