Into how many temperature zones the earth can be divided?

geography environmental changes elements of weather and climate : temperature process of heat transfer in the atmosphere environmental regions (zones)

  1. Two

  2. Three

  3. Four

  4. Five

Show answer
Correct Option: C
Explanation:

The earth can be divided into four temperature zones. They are, 

1. Torrid zone:  It extends on both sides of the equator bounded by the tropic of cancer and tropic of Capricorn. In this area sun's rays are more or less perpendicular. The temperature in this area is always high.
2. North Temperate zone: This area is between tropic of cancer and Arctic circle in the northern hemisphere. Sun rays do not fall perpendicularly nor slanting at this place. So places within this area neither too hot not too cold.
 3. South Temperate zone: This area is between the Tropic of Capricorn and Antarctica circles. Here temperature is neither too hot nor too cold.
4. Frigid zone: The frigid zone in the northern hemisphere lies Arctic circle and the North Pole and in the southern hemisphere between Antarctic circle and south pole. They receive very little heat from the sun and hence very cold.

The solar energy which reaches the earth in the form of short waves is called ____.

  1. ultravioletrays

  2. global warming

  3. insolation

  4. radiation

Show answer
Correct Option: C
Explanation:

Our sun is the main source of energy and heat. It provides solar energy or fuel for the process of weather and climate. The energy emitted by the sun is known as solar radiation. The incoming radiation to the earth is known as isolation and it reaches in the earth in form of short waves.

Sensitivity of a thermometer refers to _________.

geography environmental changes elements of weather and climate : temperature process of heat transfer in the atmosphere environmental regions (zones)

  1. Amount of change in thermometric property for a unit change in temperature

  2. Minimum and maximum temperatures that thermometer can measure

  3. How quickly thermometer can register change in temperature

  4. None of these

Show answer
Correct Option: A
Explanation:

Sensitivity of a thermometer refers to the amount of change in thermometric property for a unit change in temperature. It refers to the smallest temperature change that can be detected or measured. The range of a thermometer on the other hand refers to the difference between the maximum and the minimum temperature.

In which type of farming, roof is made of either glass or cloth to allow the sun rays to penetrate and sustain the heat inside the building?

geography environmental changes elements of weather and climate : temperature process of heat transfer in the atmosphere environmental regions (zones)

  1. Organic farming

  2. Greenhouse farming

  3. Inorganic farming

  4. All of the above

Show answer
Correct Option: B
Explanation:

In greenhouse farming, the roof is made of either glasses or cloth to allow the sun rays to penetrate and sustain the heart of the building. In this method of farming the dependency on climate reduces. Mainly flower, vegetable, fruits are grown in greenhouse farming.  Some crops also are grown in this method.  With increasing technology greenhouse farming also increasing day by day. 

Which gas can hold the heat in the atmosphere for a long time?

geography environmental changes elements of weather and climate : temperature process of heat transfer in the atmosphere environmental regions (zones)

  1. Oxygen

  2. Nitrogen

  3. Carbon di oxide

  4. Ozone

Show answer
Correct Option: C
Explanation:

Carbon dioxide can hold the heat in the atmosphere for a long time. It constitutes only 0.03 percent of the dry air. Being an effective absorber of heat from the upper atmosphere as well as the earth, carbon dioxide is considered to be of great climatic significance. This gas emits about half of the absorbed heat back to the earth.

The lines which connects places of equal temperature are called ___________.

geography environmental changes elements of weather and climate : temperature process of heat transfer in the atmosphere environmental regions (zones)

  1. isohytes

  2. isobars

  3. isotherms

  4. contours

Show answer
Correct Option: C
Explanation:

The places having similar temperature conditions are joined by means of imaginary lines known as isotherms. For convenience, the temperature is reduced to sea level as if the places actually existed at sea level. The isotherms have east-west trends and generally follow the latitude. 

The highest recorded temperature is about $58^oC$ at Al-Aziziyah which is in ____________.

geography environmental changes elements of weather and climate : temperature process of heat transfer in the atmosphere environmental regions (zones)

  1. Libya

  2. Algeria

  3. Niger

  4. Sudan

Show answer
Correct Option: A
Explanation:

The highest recorded temperature is about 58 $^oC$ at Al-Aziziyah which lies in Libya. It is located around 25 miles south of Tripoli. World Meteorological Organization had recorded this temperature on 13 September 1922. After exactly 90 years, on 13 September 2012, this record was disqualified. Now, the highest recorded temperature is in Death Valley, California.

The mean annual temperature of a country varies between $7^oC\,\, to\,\, 17^oC$. This country lies in the.

geography environmental changes elements of weather and climate : temperature process of heat transfer in the atmosphere environmental regions (zones)

  1. Alpine climate region

  2. Sub-tropical region

  3. Temperate region

  4. Tropical region

Show answer
Correct Option: C
Explanation:

The Köppen climate classification defines a climate as "temperate" when the mean temperature is above −3 °C (26.6 °F) but below 18 °C (64.4 °F) in the coldest month.

Global warming and climate change are two different concepts.

geography environmental changes elements of weather and climate : temperature process of heat transfer in the atmosphere environmental regions (zones)

  1. Yes

  2. No

  3. Can't say

  4. None of these

Show answer
Correct Option: A
Explanation:

Yes,

The term "climate change" is often used to refer specifically to anthropogenic climate change (also known as global warming). Anthropogenic climate change is caused by human activity, as opposed to changes in climate that may have resulted as part of Earth's natural processes.

Greenhouse effect is a ________ phenomenon to keep the climate warm up.

geography environmental changes elements of weather and climate : temperature process of heat transfer in the atmosphere environmental regions (zones)

  1. Natural

  2. Commercial

  3. Both A and B

  4. None of these

Show answer
Correct Option: A
Explanation:

A greenhouse is a body which allows the shortwave incoming solar radiation to come in but does not allow the longwave outgoing terrestrial infrared radiation to escape. The greenhouse effect is a natural phenomenon which helps in keeping the earth's surface warm up. Carbon dioxide, water vapour etc are the important gases of the greenhouse.
