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

Which one of the following is the region of cold temperature? 

  1. Mesosphere

  2. Thermosphere

  3. Ionosphere

  4. Exosphere
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
A. Mesosphere is the layer just above the stratosphere and extends from 50-85 km. Temperature is about -90° C in this region.
B. Thermosphere is the layer above the mesosphere. Ultraviolet radiations can penetrate this layer and causes photodissociation of molecules. Temperature increases in this region.
C. Ionosphere is the region of upper atmosphere of Earth that extends from 60-1000 km. Ionization by solar radiation occurs in this region.
D. Exosphere is the outermost layer of Earth's which hardly contains air.
Hence,the region of cold temperature is Mesophere.
So, the correct answer is 'Mesophere'.
Multiple choice biology global environmental change causes of greenhouse effect greenhouse effect pollution and its effects

High concentration of greenhouse gases has resulted in maximum rise of atmospheric temperature in 

  1. Tropic region

  2. Middle latitude

  3. Polar region

  4. Temperate region
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Increases in the level of greenhouse gases has led to considerable heating of earth leading to global warming. During the past century, the temperature of earth has increased by $ 0.6  $, most of it during the last three decades. Rise in temperature is slight in tropics, moderate in middle latitudes and maximum in polar regions. It will led to melting of polar ice caps as well as of other places like the Himalayan snow caps.
So, the correct answer is 'Polar region'.
Multiple choice biology animal world oviparous and viviparous diversity and classification in animals adaptations in animals

Which of the following is incorrect match?

  1. Polar bear - Eurythermal

  2. Archaebacteria - Hydrothermal vents

  3. Cyanobacteria - Thrive in Antarctic water

  4. Desert lizards - Body temperature fairly constant
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
  • Polar bears are stenothermal because they can tolerate only a narrow range of temperature and are restricted to specific regions only. On the other hand, eurythermal animals can tolerate a wide range of temperature variations and thus have a wider distribution on earth.
  • Archaea are microorganisms that define the limits of life on Earth. They were originally discovered and described in extreme environments, such as hydrothermal vents and terrestrial hot springs. 
  • Cyanobacteria can be found in almost every terrestrial and aquatic habitat—oceans, freshwater, damp soil, temporarily moistened rocks in deserts, bare rock, and soil, and even Antarctic habitats, some of the driest and coldest ecosystems on the Earth.
  • Ectotherms like desert lizards do not use metabolic heat to maintain their body temperature but manage to keep their body temperature fairly constant by behavioural means. They bask in the sun and absorb heat when their body temperature drops below the comfort zone but move in to shade when the ambient temperature starts increasing.
  • So the incorrectly matched option is A.

Multiple choice chemistry planet earth acid deposition air and air pollution natural resources- air, water and land

Which of the following is a wet deposition of acid rain?

  1. Fog

  2. Rain

  3. Snow

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

Wet deposition is rain, sleet, snow, or fog that has become more acidic than normal. Wet deposition of acids occurs when any form of precipitation removes acids from the atmosphere and delivers it to the Earth's surface.

Multiple choice chemistry planet earth acid deposition air and air pollution natural resources- air, water and land

Rain, snow or fog, which is acidic in nature, is known as:

  1. acid rain

  2. acid snow

  3. acid fog

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

Acid rain includes any form of precipitation with acidic components from the atmosphere.

This can include rain, snow, fog, hail or even dust that is acidic.
This happens when oxides of sulphur and nitrogen that are emitted by the industries react with water and oxygen in the atmosphere to form sulphuric acid and nitric acid respectively.
These acids are responsible for the acidic nature of the rains. Their pH is usually between 5.5 to 5.
Thus, the correct answer is option (A).

Multiple choice chemistry planet earth acid deposition air and air pollution natural resources- air, water and land

Low visibility in cold weather is due to:

  1. formation of fossil fuel

  2. unburnt carbon particles or hydrocarbons suspended in air

  3. lack of adequate power supply

  4. none of these
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Smog is a dark brown or greyish smoky mist that occurs in cold weather. It is formed by unburnt carbon particles or hydrocarbons suspended in the air. It is a visible indication of air pollution. Smog not only reduces visibility but is highly suffocating and harmful to human beings, animals and plants.


Hence, the correct option is $B$

Multiple choice chemistry planet earth acid deposition air and air pollution natural resources- air, water and land

Which of the following is correct about acid rain?

  1. Rain which is acidic in nature

  2. Rain which is basic in nature

  3. Rain which is neutral in nature

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

When oxides of sulphur and nitrogen which are emitted by the industries, react with the moisture present in the atmosphere, they form acids.

Thus, these acids reduce the pH of the rain falling on the Earth and hence acid rain is acidic in nature.
It's pH acid  rain is 5.5
Hence, the correct answer is option (A).
