Answer:
Temperature is measured mainly by two units—
- Degree Celsius (°C) and
- Degree Fahrenheit (°F).
Question 102. What is albedo?
Answer:
Albedo:
About 34% of the sun’s radiation is reflected back into space as long waves. These waves cannot heat the atmosphere or the earth’s surface. This is known as the albedo of the earth.
Question 103. What is effective radiation?
Answer:
Effective radiation:
About 34% of the sun’s radiation returns to space as the earth’s albedo. The rest 66% of solar energy heats up the atmosphere directly (19%) or by radiation of heat from the earth’s surface (47%). This energy that heats up the earth’s atmosphere is known as effective radiation.
Question 104. What is the ‘solar constant’?
Answer:
Solar constant:
The total amount of solar radiation received by a black body (a hypothetical perfect absorber and radiator of energy) on the earth’s surface through perpendicular rays per unit of time and per unit of area at a mean distance between the earth and the sun is known as the ‘solar constant’. It is about 1370 watts per sq. km.
Question 105. Which part of the earth is referred to as the Torrid zone?
Answer:
The region of the earth lies between 23½º and 66½º The average temperature of the earth is The average temperature of this zone is around 27°C. This zone does not undergo many climatic changes.
Question 106. Which part of the earth is known as the temperate zone?
Answer:
The region of the earth lying between 2334° and 6634° latitudes in both hemispheres is known as the temperate zone. The average temperature of this zone varies between 0° and 27°C. This zone can be further subdivided into a warm temperate zone and a cool temperate zone.
Question 107. Which part of the earth is known as the Frigid zone?
Answer:
The region of the earth extending between 6634° and 90° latitudes in both hemispheres is known as the Frigid zone. The average temperature of this zone is about 0°C. Like the equatorial region, this region also does not experience many climatic changes throughout the year.
Answer:
Average monthly temperature Total of the daily average temperature / No. of days in the month = 1078.6c /21 =34.79°C
Question 109. What is Six’s maximum and minimum thermometer?
Answer:
Six’s maximum and minimum thermometer
The Six’s maximum and the minimum thermometer is an instrument that measures the maximum and minimum temperature of a day. It also helps to calculate the average temperature and the diurnal range of temperature.
Question 110. By which processes is the atmosphere heated?
Answer:
The atmosphere is mainly heated by the processes of convection, conduction and radiation. Apart from these, it is also heated by advection, direct reflection of solar radiation, geothermal energy, the release of latent heat, vulcanism, etc.
Question 111. What do you mean by average temperature?
Answer:
Average temperature:
The sum of the highest and lowest temperatures of a place divided by two over a certain period of time is called average temperature. E.g.—If a place has the highest temperature of 30°C and the lowest of 16°C, the average temperature of the day is:
30°C + 16°C /2 = 46°C/2 = 23oC
Question 112. What is the heat equator?
Answer:
Heat equator:
- The ‘heat equator’ or the ‘thermal equator’ is an imaginary line around the earth running across all the meridians and joining the places having the highest average temperature on each meridian.
- This line more or less follows the 5°N latitude due to the presence of large landmasses and therefore greater summer heating.
Question 113. What is advection?
Answer:
Advection:
The lateral or horizontal motion of transfer of heat from warm to cool regions along the surface of the earth is known as advection. Eg- Heat is transferred from the warm equatorial region to the cold polar regions by the advection movement of the air.
Question 114. What are periodic winds? Give examples.
Answer:
Periodic winds
The winds generated over the earth in the atmosphere at certain fixed times of the year are called periodic winds. Examples- A land breeze, sea breeze, monsoon winds, etc.
Question 115. How can a temperature-rainfall diagram prove whether the area is in the northern or southern hemisphere?
Answer: If the temperature graph in the rainfall-temperature diagram appears to be convex, then the place is located in the northern hemisphere. If the curve appears concave, the place lies in the southern hemisphere.
Question 116. How can tundra climate be identified with the help of a rainfall temperature diagram?
Answer: In a rainfall-temperature diagram, if the temperature curve shows temperature below the freezing point for 8-9 months a year and the range of temperature is quite high, the climate thus indicated is a tundra climate.
Question 117. How can a hot-desert climate be identified with the help of a rainfall-temperature diagram?
Answer: In a rainfall-temperature diagram, if the temperature curve shows a huge difference between summer and winter conditions, and rainfall is very scanty and negligible, the climate thus indicated is a hot desert climate
Question 118. What is drizzle?
Answer:
Drizzle
Sometimes precipitation may occur in the form of very tiny droplets (<0.5 mm diameter) continuously from nimbostratus clouds. The droplets are so tiny that they seem to float in the air. This is called drizzle. Drizzles may occur often during the rainy season.
Question 119. What do you mean by super-saturated air?
Answer:
Super-saturated air?
If any special geographical area contains more water vapor in the air than is needed to make the air saturated at that particular temperature, the air is said to be supersaturated to understand the distribution of rainfall throughout the earth.
Question 120. Explain the process of radiation.
Answer:
Process of radiation:
The process of transfer of heat from one place to another without the help of any medium or without heating the medium present in between, is called radiation.
Eg- The earth’s surface radiates back solar energy through long waves and heats up the atmosphere. Radiation occurs faster in days of cloudless clear skies..
