Multiple choice physics heat and energy causes of greenhouse effect global warming adaptation in animals

When we are near to ice, why do we feel cold?

  1. Because our body temperature is higher than the surrounding temerature

  2. Because there is ice near to us

  3. Because we wear warm cloth

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

When we are nearer to the ice, our body temperature is higher than the surrounding temperature. So heat flows from out body to the surrounding resulting in lowering the body temperature. Thus we feel cold when being nearer to the ice.

The global warming has resulted in

  1. the increase in yield of crops

  2. the decrease in sea levels

  3. the decrease in human deaths

  4. the increase in sea levels
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Two major mechanisms are causing sea level to rise.
First, shrinking land ice, such as mountain glaciers and polar ice sheets, is releasing water into the oceans.
Second, as ocean temperatures rise, the warmer water expands. 
The warming of the atmosphere caused by increases in greenhouse gases is melting glaciers and causing ocean water to warm and expand thermally. Both effects increase the volume of the ocean, raising its surface level.
Thus Option D is correct.

Why do we feel cold during winter?

  1. Because our body temperature is higher than surrounding temperature

  2. Because our body temperature is lower than surrounding temperature

  3. It doesn't depend on our body temerature

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

During winter, our body temperature is higher than the surrounding temperature. So heat flows from out body to the surrounding resulting in lowering the body temperature. Thus we feel cold during winter.

What causes wind currents across the globe?

  1. The gravitational pull of the earth

  2. Change in season

  3. Uneven heating of earth surface

  4. Gravitational pull of the sun.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Wind currents are generated across the globe due to the uneven heating of the earth surface by the sun, creating temperature and pressure differences in the atmosphere.

Multiple choice physics heat and energy causes of greenhouse effect global warming adaptation in animals

When we use blanket why do we feel warm?

  1. Because the blanket is warm

  2. Because the blanket doesn't allow air to enter

  3. Because our body is warm

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

Cold air tries to carry body heat away. Blankets form a barrier between the body and cold air. Hence heat doesn't transfer through the blankets as air will not flow through the blankets.

Multiple choice physics heat and energy causes of greenhouse effect global warming adaptation in animals

Without green house effect, the average temperature of earths surface would have been :

  1. $-18^{\circ}C$
  2. $33^{\circ}C$
  3. $0^{\circ}C$
  4. $15^{\circ}C$
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

If an ideal thermally conductive black body were the same distance from the Sun as the Earth is, it would have a temperature of about 5.3 C. However, since the Earth reflects about 30% of the incoming sunlight, this idealized planet's effective temperature (the temperature of a black body that would emit the same amount of radiation) would be about 18 C. The surface temperature of this hypothetical planet is 33 C below Earth's actual surface temperature of approximately 14 C. The mechanism that produces this difference between the actual surface temperature and the effective temperature is due to the atmosphere and is known as the greenhouse effect.
Thus Option A is correct.

How will global warming effect the sea level.

  1. rise

  2. climate change

  3. effect on whether

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

    Due to global warming the temperature of earth's atmosphere in increasing , and the temperature at poles and high mountains is also increasing . This increase in temperature will melt the ice on poles and peaks of mountain and will melt the glaciers . This will result in rise in the level of sea .

Multiple choice physics heat and energy causes of greenhouse effect global warming adaptation in animals

Which of the following is/are correct regarding global warming?

  1. Ozone becomes harmful

  2. Economic consequences

  3. Increasing temperature

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

Due to global heating temperature of the atmosphere increases,which inturns requires its controlling measures that consequently involves new technologies and hence becomes a burden in terms of money.

Multiple choice physics heat and energy causes of greenhouse effect global warming adaptation in animals

Which of the following is true regarding future effects of global warming?
A. Hurricanes will get worse and hurricanes like katrina will be common on the coastal area.
B. In the next century the sea level is predicted to rise between $9$ and $88$ cm.
C. The global temperature would increase by $2.5$ to $10$ degrees F.

  1. Only A

  2. Only B

  3. Only A and B

  4. All A , B and C
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

A hurricane is a large rotating storm with high speed winds that forms over warm waters in tropical areas. According to 2006 studies by the National Oceanic and Atmospheric Administration, the strongest hurricanes in the present climate may be upstaged by even more intense hurricanes over the next century as the Earth's climate is warmed by increasing levels of greenhouse gases in the atmosphere. Hurricanes will get worse and hurricanes like katrina will be common on the coastal area. It is predicted that the global temperature would increase by $2.5^0F$ to $10^0F$. 

Earth’s warming climate is causing sea levels to rise in two different ways. First, warmer air temperatures are causing glaciers and land ice to melt. As the melt water flows into the ocean, the increase in the total amount of water causes the sea level to rise. Second, as ocean water warms, it expands—pushing water farther up along our shores and resulting in physical changes to ocean heat and temperature. In the next century the sea level is predicted to rise between $9\,cm$ to $88\,cm$.

Multiple choice physics heat and energy causes of greenhouse effect global warming adaptation in animals

Which of the following may be the cause of greenhouse effect?

  1. Burning of fossil fuel like coal in the industries for producing electricity.

  2. Burning of fossil fuel leads to high emissions of carbon di-oxide gas.

  3. Nitrous oxide, also a green house gas is produced during nylon and nitric acid production.

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

A greenhouse gas is a gas that absorbs and emits radiant energy within the thermal infrared range. Greenhouse gases cause the greenhouse effect on planets. The primary greenhouse gases in Earth's atmosphere are water vapour $(H _2O)$, carbon dioxide $(CO _2)$, methane $CH _4)$, nitrous oxide $(N _2O)$ and ozone $(O _3)$. 

Carbon dioxide enters the atmosphere through burning fossil fuels (coal, natural gas, and oil), solid waste, trees and other biological materials, and also as a result of certain chemical reactions. Nitrous oxide is emitted during nylon and nytric acid production, agricultural and industrial activities, combustion of fossil fuels and solid waste, as well as during treatment of wastewater.
