Which of the following heat zone receive minimum Insolation?

geography temperature process of heat transfer in the atmosphere temperature and insolation sun: the ultimate source

  1. Torrid Zone

  2. Tempearate Zone

  3. Frigid Zone

  4. None of these

Show answer
Correct Option: C
Explanation:

The regions of the earth to the north of the Arctic Circle and to the south of the Antarctic Circle are collectively called as the Frigid Zone or the Polar Region. The sun does not come vertically above these regions at any time in a year. Throughout the year Frigid Zone receives slanting sun rays and hence experience a very cold climate. Most of the land there is covered with permanent ice. 

 which of the following cities can never have the sunshine directly overhead at noon?

  1. Bengaluru

  2. Mumbai

  3. Visakhapatnam

  4. Delhi

Show answer
Correct Option: D
Explanation:

Delhi,

The Tropic of Cancer divides the Indian sub continent into two zones- the Temperate Zone and the Tropical Zone. The northern part of India which lies in the Temperate Zone experiences cold winter season and the hot weather season. The southern part of the country which lies in the Tropical zone experiences hot season with no clear cut winter season and the Sun shines vertically overhead at least twice during any part of the year. 
While Chennai lies in the southern zone or the Tropical zone, Delhi lies in the northern zone or the warm temperate zone. This is the reason that while we can see the mid-day sun exactly overhead twice a year at Chennai , one is not able to do so even once at Delhi .

Distribution of temperature is uniform on the earth's surface.

  1. True

  2. False

Show answer
Correct Option: B
Explanation:

The temperature is not uniformly distributed on the earth's surface.  Temperature varies at different altitudes of the atmosphere at different places over the surface of the earth and even at different times during a day or during a month or during a year. There are several factors that control temperature variations on the earth's surface. 

Identify the Heat Zone with the help of given information:

  1. The Sun is never directly overhead
  2. The climate is mild, generally ranging from warm to cool
  3. The four annual seasons, spring, summer, autumn and winter occur in this region

geography temperature process of heat transfer in the atmosphere temperature and insolation sun: the ultimate source

  1. Temperate Zone

  2. Torrid Zone

  3. Frigid Zone

  4. Torrid as well as Frigid Zone

Show answer
Correct Option: A
Explanation:

Average yearly temperatures in these regions are not extreme, not burning hot nor freezing cold. Temperate remains moderate. Unlike in the tropical zones, temperatures can change greatly in temperate zone, between summer and winter. So, most places with a temperate climate have four seasons: summer, autumn, winter and spring.

At which place will you find maximum sunlight in December?

  1. Kanniyakumari

  2. Pune

  3. Kolkata

  4. Leh

Show answer
Correct Option: A
Explanation:
Kanniyakumari
Kanyakumari is nearest to the Tropic of Capricorn, and the sun's rays fall vertically here during December.

______________ is the radiant energy emitted by the sun from a nuclear fusion reaction that creates electromagnetic energy.

  1. Solar Radiations

  2. Alpha Radiations

  3. Beta Radiations

  4. None of these

Show answer
Correct Option: A
Explanation:

Solar radiation is the radiant energy emitted by the sun from a nuclear fusion reaction that creates electromagnetic energy.
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.

Electromagnetic spectrum consists of

  1. Alpha radiation

  2. Gamma radiation

  3. Beta radiation

  4. All of these

Show answer
Correct Option: D
Explanation:

The electromagnetic spectrum is the range of all possible frequencies of electromagnetic radiation. There are 7 regions in the electromagnetic spectrum and they are gamma rays, x-rays, ultraviolet, visible light, infrared, microwaves and radio waves. All types of electromagnetic radiation are transverse waves and they all travel at the same speed in a vacuum.  The regions of the electromagnetic spectrum are explained below in order of increasing wavelength and decreasing frequency.

The sun's radiation is made up of  _________.

  1. white light, infrared and ultraviolet radiation

  2. red light, infrared and ultraviolet radiation

  3. green light, infrared and ultraviolet radiation

  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 __________.

  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.
