Atmosphere comprises of

  1. Lithosphere and hydrosphere

  2. Lithosphere, hydrosphere, stratosphere and ionosphere

  3. Troposphere, stratosphere and ionosphere

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

Atmospheric layers include the troposphere (0 to 16 km), stratosphere (16 to 50 km), mesosphere (50 to 80km) and thermosphere (80 to 640km). In the troposphere and mesosphere, temperature generally falls with increasing altitude, while in the stratosphere and thermosphere, temperature rises with increasing altitude. In addition to temperature, other criteria can be used to define different layers in the atmosphere. 

The ionosphere, which occupies the same region of the atmosphere as the thermosphere, is defined by the presence of ions, a physico-chemical criterion. 
The region beyond the ionosphere is known as the exosphere. The ionosphere and the exosphere together make up the upper atmosphere (or thermosphere). The magnetosphere is the region above the Earth's surface in which charged particles are affected by the Earth's magnetic field.

  3. Nitrogen zone

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

Exosphere is the outer fringe of Earth's atmosphere, which extends some 20000 miles from the planet. It's dominant element is hydrogen and its temperature ranges from $200^0 F$ to $1000^0 F$. The lower part of exosphere contains abundance of helium besides hydrogen and is called as “helium zone”. Hence, option D is correct.

The environment is composed of

  1. Lithosphere, Hydrosphere, Atmosphere

  2. Lithosphere and Stratosphere

  3. Troposphere and Stratosphere

  4. Lithosphere and Hydrosphere
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Lithosphere consists of the earth's core, the mantle, crust, ocean floor, mountains, sand, rocks, etc.
Hydrosphere is made of everything that includes water such as oceans, rivers, lakes, rain and ice caps.
Atmosphere is made of gasses such as oxygen, hydrogen, water vapor, ozone, and the wind.
All the three make up the environment. 
Thus, the correct answer is option 'Lithosphere, Hydrosphere, Atmosphere'.
