  3. 4th May

  4. 5th June

Show answer
Correct Option: D
Explanation:

Every year 'World Environment Day' is celebrated on 5th of June by 'United Nations Environment Programme'. 

Which one is not a component of environment?

evs - i interdependence in our environment meaning of environment significance of biodiversity habitat and adaptation

  1. Sunlight

  2. Decomposers

  3. Water

  4. Air

Show answer
Correct Option: B
Explanation:

Environment is defined as a natural ecosystem that includes everything around the biotic factors. These are nonbiotic factors. These includes air, water, sunlight. Decomposers are the biotic factors of an ecosystem.

Thus, the correct answer is 'Decomposers.'

  1. Selection

  2. Introduction

  3. Acclimatization

  4. Quarantine

Show answer
Correct Option: C

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

evs - i interdependence in our environment meaning of environment significance of biodiversity habitat and adaptation

  1. Photosphere

  2. Chromosphere

  3. Terrestrial

  4. None o fthese

Show answer
Correct Option: A
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 

evs - i interdependence in our environment meaning of environment significance of biodiversity habitat and adaptation

  1. Lithosphere

  2. Thermosphere

  3. Ozonosphere

  4. None of the above

Show answer
Correct Option: B
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

evs - i interdependence in our environment meaning of environment significance of biodiversity habitat and adaptation

  1. Mesosphere

  2. Stratosphere

  3. Trophosphere

  4. Thermosphere

Show answer
Correct Option: C
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.

Strengthening of concept of environmental monitoring is important for concern of the 

evs - i interdependence in our environment meaning of environment significance of biodiversity habitat and adaptation

  1. Quality of environment

  2. Quantity of environment

  3. Quality of monitor

  4. Pure air

Show answer
Correct Option: A
Explanation:

Environmental monitoring describes the processes and activities that need to take place to characterize and monitor the quality of the environment. It can be defined as the systematic sampling of air, water, soil and biota in order to observe and study the environment. 

Therefore, the correct answer is option A.

Atmosphere comprises of

evs - i interdependence in our environment meaning of environment significance of biodiversity habitat and adaptation

  1. Lithosphere and hydrosphere

  2. Lithosphere, hydrosphere, stratosphere and ionosphere

  3. Troposphere, stratosphere and ionosphere

  4. None of the above

Show answer
Correct Option: C
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.
