What are the characteristics of Contour lines ?

  1. Steep slopes.

  2. Gentle slopes

  3. Summits.

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

Contour lines are used to represent various landforms, including steep slopes (lines close together), gentle slopes (lines far apart), and summits (closed concentric circles). Therefore, all these features are characterized by contour lines.

Which one is not a component of environment?

  1. Sunlight

  2. Decomposers

  3. Water

  4. Air
Reveal answer Fill a bubble to check yourself
B Correct answer
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.'

C Correct answer
Explanation

Acclimatization is the process by which an individual organism adjusts to a change in its environment, allowing it to maintain performance across a range of environmental conditions.

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

  1. Photosphere

  2. Chromosphere

  3. Terrestrial

  4. None o fthese
Reveal answer Fill a bubble to check yourself
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.

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

  1. Quality of environment

  2. Quantity of environment

  3. Quality of monitor

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

  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.
