A $400$km thick, bright layer around the sun is known as _______.

  1. Photosphere

  2. Chromosphere

  3. Terrestrial

  4. None o fthese

A Correct answer
Explanation

Photosphere is the lowest layer around the sun in which the energy of the sun is emitted as light. Due to this the layer appears bright. It is approximately 400 km in thickness. So, the correct option is 'Photosphere'.

Ionosphere is also known as 

  1. Lithosphere

  2. Thermosphere

  3. Ozonosphere

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The ionosphere is defined as the layer of the Earth's atmosphere that is ionized by solar and cosmic radiation. It lies 75 to 1000 km above the Earth. It is distinguished because it is ionized by solar radiation. It plays an important part in atmospheric electricity and forms the inner edge of the magnetosphere. It has practical importance because, among other functions, it influences radio propagation to distant places on the Earth. It is also called as thermosphere.

The lower most layer of atmosphere in which man and other living organisms exist, is called as

  1. Mesosphere

  2. Stratosphere

  3. Trophosphere

  4. Thermosphere
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The troposphere is the lowest layer of Earth's atmosphere and site of all weather on Earth. The troposphere is bonded on the top by a layer of air called as the tropopause, which separates the troposphere from the stratosphere, and on bottom by the surface of the Earth. It contains approximately 75% of the atmosphere's mass and 99% of its water vapour and aerosols. The average depth of the troposphere is approximately 17 km in the middle latitudes.
