Earth's surface temperature can be altered, by changing concentration of

  1. Heat

  2. Greenhouse Gases

  3. Air pollutants

  4. All of above

Reveal answer Fill a bubble to check yourself

Global climatic changes will affect ___________ in many places, due to affects of soil erosion and reduced rainfall, on agricultural production.

  1. incomes of people

  2. food security

  3. employment level

  4. demand of goods

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
Global warming refers to an increase in the average temperature of the globe due to heat that gets trapped in the atmosphere because of which the surface of the earth is heated. Global warming has caused global climatic changes that have hampered food security as a result of soil erosion and reduced rainfall, or events of extreme rainfall.

_______  is a gradual increase in the average temperature of the earth's lower atmosphere as a result of the increase in greenhouse gases since the _____.

  1. Ozone depletion, Industrial Revolution

  2. Global warming, Industrial revolution

  3. Global warming, Green revolution

  4. Ozone depletion, Green revolution

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The Industrial Revolution spanned the 18th and early 19th Century. Over this period, global CO2 emissions were a fraction of current levels. During the 18th Century, global CO2 emissions were around 3 to 7 million tonnes per year. During the early 19th Century, CO2 emissions steadily rose reaching 54 million tonnes per year by 1850. Currently we are emitting over 8000 million tonnes per year.

Global warming is the consequence of the over proportional activities of the humans on the earth such that what the earth stored and built in very long time is to be consumed in a very short time. This disturbs much the dynamic balance on the earth leading to huge production of substances and gases such as the carbon dioxide that can not be reprocessed again by the earth and remains in the environment. 
The recent  industrial civilization is based on machines driven by energy taken from fossil fuels. It has good achievements but the cost is very serious. The cost is the environmental pollution especially CO2 as it leads to global warming which can has unseen serious effects on our climate.

Multiple choice zoology global environmental change causes of greenhouse effect global warming adaptation in animals

In the event of global warming, which one of the following is most likely to occur?

  1. Existing plant and animal communities will move North in response to warming.

  2. Agriculture in the prairie provinces will be redeveloped on soils of the Canadian Shield.

  3. The anticipated rise in sea level will be caused primarily by the melting of polar ice caps.

  4. The decomposition of organic matter in the unfrozen surface layer of polar soils will increase.

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
It is believed that increase in concentration of greenhouse gases has resulted in rise of atmospheric temperature which is slight in tropics, moderate in middle latitudes and maximum in polar regions. Global warming could raise sea level due to thermal expansion of sea water, melting of glaciers and Greenland ice sheet. There is a danger of submersion of large area as one third of human population lives within 60 km of coastline. Coastal salt marshes and estuaries, wetlands, drylands, freshwater supplies, fisheries, fish breeding areas and other types of wildlife will undergo extinction.
So, the correct answer is 'The anticipated rise in sea level will be caused primarily by the melting of polar ice caps'.
Multiple choice zoology global environmental change causes of greenhouse effect global warming adaptation in animals

Which of the following would happen in the presence of greenhouse effect in the atmosphere?

  1. Pollution will increase

  2. The earth's surface temperature will increase

  3. The earth's surface temperature remains the same,

  4. The depleted ozone layer will decrease the earth's temperature.

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Greenhouse gas like co$ _2$, methane, CFC absorbs the radiation reflected from the earth's surface in the form of heat and increases the atmosphere's temperature is called as greenhouse effect which leads to the global warming.

What immediate hazard is likely to occur if the temperature of the earth rises by 5$^oC$?

  1. Increase in productivity

  2. Melting of polar ice

  3. Destruction of phytoplanktons

  4. Inundation of coastal towns

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

While all listed options are potential consequences of climate change, the melting of polar ice is a direct and immediate physical response to a significant rise in global temperature.

Multiple choice zoology global environmental change causes of greenhouse effect global warming adaptation in animals

What is the potential danger of greenhouse effect?

  1. Poor photosynthesis

  2. Heavy rainfall

  3. Coastal flooding

  4. More humidity in environment

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Coastal flooding is a major potential danger of the greenhouse effect because rising temperatures cause glaciers to melt and seawater to expand, leading to a rise in sea levels.

Multiple choice zoology global environmental change causes of greenhouse effect global warming adaptation in animals

Increased level of carbon dioxide in the atmosphere traps the heat rays reflected by the earth causing an increase in the temperature on the earth. This is

  1. Local warming

  2. House warming

  3. Global warming

  4. Country warming

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

When carbon dioxide and other air pollutants are collected in the atmosphere they absorb sunlight that has bounced from the earth’s surface. This leads to an increase in the earth's average surface temperature and is called global warming. Carbon dioxide emissions from burning fossil fuels and deforestation are the primary cause of global warming. Thus the correct answer is option C.

Multiple choice zoology global environmental change causes of greenhouse effect global warming adaptation in animals
Increased $CO _2$ concentration in the atmosphere leads to
  1. Global warming

  2. Eutrophication of lakes

  3. Depletion of the ozone layer

  4. Magnification in the food chain

  5. Acid rain

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Global warming is caused by increased atmospheric concentration of $CO _2$ and other green house gases. As greenhouse gases absorbs the solar energy when radiation is reflected back to the atmosphere from earth's surface and increase the earth's temperature. Eutrophication refers to the presence of excess organic compounds in water. Depletion of the ozone layer is caused by the excess release of chlorine and bromine-containing the chemical in the atmosphere. Acid rain is the result of increased sulphur and nitrogen oxide levels in the atmosphere. Slow metabolism and excretion of pesticides causes their accumulation in fat tissues of organisms and is referred to as biomagnifications. The correct answer is A.

Multiple choice zoology global environmental change causes of greenhouse effect global warming adaptation in animals

Which of the following would happen in the absence of greenhouse effect in the atmosphere?

  1. Pollution will increase.

  2. The earth's surface temperature will decrease.

  3. The earth's surface temperature remains the same.

  4. The depleted ozone layer will increase the earth's temperature.

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

When carbon dioxide and other air pollutants are collected in the atmosphere they absorb sunlight that has bounced from the earth’s surface. This leads to an increase in the earth's average surface temperature and is called global warming. When there is no effect of the global warming, the temperature of the Earth's surface will decrease. 

Thus, the correct answer is option B.
