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. 

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

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

  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

Show answer
Correct Option: D

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

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

  1. mars

  2. pluto

  3. moon

  4. earth

Show answer
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 ________.

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

  1. electrons

  2. neutrons

  3. protons

  4. mesons

Show answer
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.

Which of the following is transmitted in long wave?

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

  1. solar radiation

  2. Heat radiation

  3. Both a and b

  4. None of these

Show answer
Correct Option: A
Explanation:

Solar radiation transmits longwave radiation.
Solar radiation is radiant energy emitted by the sun from a nuclear fusion reaction that creates electromagnetic energy. The spectrum of solar radiation is close to that of a black body with a temperature of about 5800 K. About half of the radiation is in the visible short-wave part of the electromagnetic spectrum.

Terrestrial radiation is long waves _________.

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

  1. radiated by the earth 

  2. reflected by the earth

  3. both A and B

  4. none of these

Show answer
Correct Option: A
Explanation:

Radiation is the direct heating by the transmission of the heat waves. The upper layer of the atmosphere absorbs some amount of heat of the sun as they pass through the atmosphere. Radiation from the earth is called terrestrial radiation. Terrestrial radiation is long wave radiated by the earth. 

Only one part of ____________ billion parts of sun's radiation reaches the earth.

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

  1. 2

  2. 3

  3. 4

  4. 5

Show answer
Correct Option: A
Explanation:

Only one part of 2 billion parts of sun's radiation reaches the earth.
The sun's radiation must make it through multiple barriers before it reaches Earth's surface. The first barrier is the atmosphere. About 26% of the sun's energy is reflected or scattered back into space by clouds and particulates in the atmosphere 34. Another 18% of solar energy is absorbed in the atmosphere.

The amount of solar radiation reflected by the earth is called as its _______.

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

  1. Albedo

  2. Scattering

  3. Refraction

  4. Dispersion

Show answer
Correct Option: A
Explanation:

A part of the solar radiation falling on any surface is reflected back. Thus a certain amount of energy is lost and it does not play any role in heating the atmosphere. The reflectivity of a substance usually expressed as a percentage of the incident radiation reflected is known as it's albedo or reflection coefficient. It differs from place to place as well as from time to time.
