  4. blue light, infrared and ultraviolet radiation

Show answer
Correct Option: A
Explanation:

White light, infrared and ultraviolet radition
Radiation from the Sun. Radiation from the Sun, which is more popularly known as sunlight, is a mixture of electromagnetic waves ranging from infrared (IR) to ultraviolet rays (UV). It of course includes visible light, which is in between IR and UV in the electromagnetic spectrum.

The amount of the solar energy received by the earth is called _________.

geography environmental changes elements of weather and climate : temperature process of heat transfer in the atmosphere environmental regions (zones)

  1. insolation

  2. radiation

  3. heat

  4. none of these

Show answer
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 solar radiation to the earth is known as insolation.

Solar wind contains __________.

geography environmental changes elements of weather and climate : temperature process of heat transfer in the atmosphere environmental regions (zones)

  1. atomic energy

  2. atomic heat

  3. charged particles

  4. none of these

Show answer
Correct Option: C
Explanation:

Charged particles,

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.

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

geography environmental changes elements of weather and climate : temperature process of heat transfer in the atmosphere environmental regions (zones)

  1. $5$%

  2. $10$%

  3. $51$%

  4. $65$%

Show answer
Correct Option: C

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

geography environmental changes elements of weather and climate : temperature process of heat transfer in the atmosphere environmental regions (zones)

  1. short waves

  2. medium waves

  3. long waves

  4. none of the above

Show answer
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 __________.

geography environmental changes elements of weather and climate : temperature process of heat transfer in the atmosphere environmental regions (zones)

  1. Pressure and wind

  2. Altitudes

  3. Latitudes

  4. Increasing distance from the sea

Show answer
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 ___________.

geography environmental changes elements of weather and climate : temperature process of heat transfer in the atmosphere environmental regions (zones)

  1. Human beings

  2. Ocean currents

  3. Moon

  4. None of these

Show answer
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 ____________.

geography environmental changes elements of weather and climate : temperature process of heat transfer in the atmosphere environmental regions (zones)

  1. Distance from the sea

  2. Ocean currents

  3. Altitude

  4. Latitude

Show answer
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 _________.

geography environmental changes elements of weather and climate : temperature process of heat transfer in the atmosphere environmental regions (zones)

  1. extreme

  2. Too little

  3. Zero

  4. Uniform

Show answer
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 _________.

geography environmental changes elements of weather and climate : temperature process of heat transfer in the atmosphere environmental regions (zones)

  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

Show answer
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.
