Different terms used for weather conditions


Exercise


A. Fill in the blanks.

  1. The condition of the atmosphere at a particular place and time is called weather.
  2. The rays of the Sun fall vertically on land near the Equator, but are slanting near the poles.
  3. The heat zone within which the Equator lies is the Torrid zone.
  4. The heat zone farthest from the Equator is the Frigid zone.
  5. The heat zone which enjoys a mild climate is the Temperate zone.
  6. The amount of water vapour in the air is known as humidity.
  7. As we go up on a mountain, it becomes cooler. (cooler/warmer)

B. True or False

  1. Climate changes from day to day. False
  2. The air in deserts has low humidity. True
  3. During the summer months, days are longer near the Equator than far away from it. True
  4. Most places in the Temperate Zone have a mild climate. True
  5. The climate near the Equator is hot and wet. True

C. Answer the following Questions.

  1. What is the difference between weather and climate?

    Answer: Weather is the condition of any place at a particular time (short period of time). And climate is the average weather conditions of that place over a long period of time.

  2. How does the climate of a place affect the people living there?

    Answer: Food habits, clothing styles, houses and activities of the people are affected by the climate of any place.

  3. Name the five important factors that determine the climate of a place.

    Answer: 
    (1) Distance from the Equator
    (2) Height above the sea level
    (3) Distance from the sea
    (4) Winds
    (5) The amount of moisture in the air (Humidity)

  4. Why do areas near the Equator receive more heat from the Sun, than those near the poles?

    Answer: The areas near the Equator are closer and in front of the Sun. The Sun rays fall directly and vertically in these areas. So the areas near the Equator receive more heat.

    The areas near the poles are little far and not directly in front of the Sun. The Sun rays fall slanting in the areas. So these areas receive lesser heat as compare to the Tropical region.

  5. Where are the following heat zones located? Describe the general climate of each zone.
    (a) Frigid Zone;
    (b) Temperate Zone;
    (c) Tropical Zone

    Answer:
    (a) Frigid Zone
    is located between the Arctic Circle (66.5°N) and the North Pole (90°N) in the Northern Hemisphere and between the Antarctic Circle (66.5°S) and the South Pole (90°S) in the Southern Hemisphere.

    Frigid Zone receives very little amount of heat from the Sun. So the climate in the Frigid Zone is generally very cold.

    (b) Temperate Zone is located between the Arctic Circle (66.5°N) and the Tropic of Cancer (23.5°N) in the Northern Hemisphere and between the Antarctic Circle (66.5°S) and the Tropic of Capricorn (23.5°S) in the Southern Hemisphere.

    Temperate Zone receives moderate amount of heat from the Sun. So the climate in the Temperate Zone is generally moderate. (Neither too cold nor too hot)

    (c) Tropical Zone (Torrid Zone) is located between the Tropic of Cancer (23.5°N) and the Tropic of Capricorn (23.5°S).

    Tropical Zone receives maximum amount of heat from the Sun. So the climate in the Tropical Zone is generally very hot.


  6. How do winds affect the climate of a place?

    Answer: Different types of winds (hot, cool, dry or full of moisture) flows in particular directions in all the areas. Winds bring heat and moisture with it. So the climate is affected by winds.

  7. How is the humidity in Chennai different from that of Jaisalmer in the Thar Desert?

    Answer: Humidity is very high in Chennai because it is very close to the sea. And humidity is very little in Jaisalmer in the Thar Desert because it is far away from the sea.

D. Multiple Choice Questions.

  1. The climate of a place is affected by
    (A) distance from the Equator.
    (B) humidity.
    (C) height above the sea level.
    (D) All of these.

  2. Which of these zones receive the maximum heat from the Sun?
    (A) Tropical Zone.
    (B) Frigid Zone
    (C) Temperate Zone
    (D) All of these receive equal amount of heat.

  3. A city is expected to have a moderate climate if it is
    (A) near the Equator.
    (B) near the sea.
    (C) near the mountains.
    (D) near the poles.

  4. If the latitude of a place is 30° N, it lies in the
    (A) Tropical Zone
    (B) North Temperate Zone
    (C) Frigid Zone
    (D) South Temperate Zone

  5. A city lies on the Equator. It is located in the plains, far away from the coast. Its climate is expected to be
    (A) hot throughout the year.
    (B) cold throughout the year.
    (C) hot in summers and cold in winters.
    (D) neither very hot nor very cold.
