Reveal answer Fill a bubble to check yourself
A Correct answer
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.

  1. electrons

  2. neutrons

  3. protons

  4. mesons
Reveal answer Fill a bubble to check yourself
A Correct answer
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.

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

  1. 2

  2. 3

  3. 4

  4. 5
Reveal answer Fill a bubble to check yourself
A Correct answer
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.

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

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

  1. Albedo

  2. Scattering

  3. Refraction

  4. Dispersion
Reveal answer Fill a bubble to check yourself
A Correct answer
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.

  4. Insolation
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
  • The energy from the sun to earth comes in the form of solar radiation while the earth radiates it back to the atmosphere in the form of terrestrial radiations, hence option B is correct.
  • Radioactivity is the energy released with the breakdown of matter in the form of gamma rays.
  • Insolation is the reduction of energy transfer between objects.

A Correct answer
Explanation

The earth receives solar energy in form of short-wave solar recitation.On the other hand solar radiation is radiated back to the atmosphere in the form of long-wave terrestrial rediation.

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

The amount of solar radiation received by the surface of the earth is called ___________.

  1. solar light

  2. heat balance

  3. terrestrial radiation

  4. insolation
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The amount of solar radiation received by the surface of the earth is called insolation. The word insolation means incoming solar radiation. It consists of a bundle of rays of radient energy of different wavelengths. The sun emits radient energy in the form of electromagnetic waves.

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

The solar radiation can be divided into ________.

  1. white light

  2. ultraviolet rays

  3. infrared rays

  4. all of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The solar radiation can be divided into three parts, namely, white light, ultraviolet rays and infrared rays.

White light: The white are also known as visible rays of the sun.  white light helps us the see any object. This light can not be seen but can be observed.
Ultraviolet rays: Ultraviolet Ray in very harmful rays come from the sun. They are responsible for many skin diseases. The wavelength is shorter than white light but longer than x rays.
Infrared rays: The wavelength of this Ray is longer than white Ray and ultraviolet rays. Most of the sun's energy comes in the form of infrared rays. This ray is also used in night vision devices.

  1. Organic farming

  2. Greenhouse farming

  3. Inorganic farming

  4. All of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In greenhouse farming, the roof is made of either glasses or cloth to allow the sun rays to penetrate and sustain the heart of the building. In this method of farming the dependency on climate reduces. Mainly flower, vegetable, fruits are grown in greenhouse farming.  Some crops also are grown in this method.  With increasing technology greenhouse farming also increasing day by day. 

Multiple choice physics observing space: telescopes maxwell's equations the nature of light introduction to electromagnetic waves

Which of the following is an electromagnetic waves that cause sunburn?

  1. ultraviolet

  2. X-rays

  3. infrared

  4. microwaves

  5. gamma rays
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

UV waves are shorter than visible light waves, so UV possesses more energy than regular light.

UV photons have the right energies to cause chemical changes. When UV light hits your skin, the DNA in your skin cells can undergo chemical change. This chemical change is what sunburn is. In extreme cases, this change in DNA can result in cancer.

Which of the following statements is / are correct ?

  1. A solar panel is made by combining a large number of solar concentrators.

  2. To work properly, wind energy generators need wind speeds of at least about 15 km/h.

  3. Many of the sources ultimately derive their energy

  4. none

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A solar concentrator uses lenses, called Fresnel lenses, which take a large area of sunlight and direct it towards a specific spot by bending the rays of light and focusing them. Some people use the same principle when they use a magnifying lens to focus the Sun's rays on a pile of kindling or paper to start fires.
