Weekly Quiz Competition
  • Question 1
    1 / -0
    The wind system in equatorial areas is known as
    Solution
    As part of the Hadley cell, surface air flows toward the equator while the flow aloft is towards the poles. A low-pressure area of calm, light variable winds near the equator is known as the doldrums, near-equatorial trough, intertropical front, or the Intertropical Convergence Zone.
  • Question 2
    1 / -0
    Fill in the blank: The winds blow from sea towards the coastal areas are called ____________.
    Solution
    In areas close to the shore, in daytime the land is warmer than the sea. Therefore the air pressure of the land is lower than the sea. As a result, wind usually blows from the sea to the land. Such type of wind is called a "sea breeze".
  • Question 3
    1 / -0
    Anticyclones are caused by
    Solution
    In an anticyclone, winds move out from a high-pressure area with wind direction clockwise in the northern hemisphere, anti-clockwise in the southern hemisphere. When it displaces the heavier nitrogen and oxygen, it causes an anti-cyclone.
  • Question 4
    1 / -0
    In the earth`s atmosphere, the atmospheric pressure
    Solution
    The air around you has weight, and it presses against everything it touches. That pressure is called atmospheric pressure, or air pressure. It is the force exerted on a surface by the air above it as gravity pulls it to Earth.Atmospheric pressure is commonly measured with a barometer.Atmospheric pressure drops as altitude increases.
    For example :The atmospheric pressure on Denali, Alaska, is about half that of Honolulu, Hawai'. Honolulu is a city at sea level. Denali, also known as Mount McKinley, is the highest peak in North America.
    So option 2 is correct.
  • Question 5
    1 / -0
    The four major components of the atmosphere are
    Solution
    According to NASA, the gases in Earth's atmosphere include:
    Nitrogen — 78 percent.
    Oxygen — 21 percent.
    Argon — 0.93 percent.
    Carbon dioxide — 0.04 percent.
  • Question 6
    1 / -0
    Which of the following occurs more frequently than the other three in the Indian Ocean?
    Solution
    Cyclone is a large scale air mass that rotates around a strong center of low atmospheric pressure. Cyclones are characterized by inward spiraling winds that rotate about a zone of low pressure.
  • Question 7
    1 / -0
    `Bilzzard` is a
    Solution
    A blizzard is a severe snowstorm characterized by strong sustained winds of at least 56 km/h (35 mph) and lasting for a prolonged period of time—typically three hours or more. A ground blizzard is a weather condition where snow is not falling but loose snow on the ground is lifted and blown by strong winds.
  • Question 8
    1 / -0
    The ozone layer in the upper part of the atmosphere protects us from
    Solution
    The ozone layer or ozone shield is a region of Earth's stratosphere that absorbs most of the Sun's ultraviolet radiation. It contains high concentration of ozone (O3) in relation to other parts of the atmosphere, although still small in relation to other gases in the stratosphere.
  • Question 9
    1 / -0
    Which of the following sequences of atmospheric layers is correct from below?
    Solution
    The atmosphere can be divided into layers based on its temperature:
    The troposphere is the lowest layer of Earth's atmosphere, and is also where nearly all weather conditions take place. It contains approximately 75% of the atmosphere's mass and 99% of the total mass of water vapor and aerosols.
    The tropopause is the boundary in the Earth's atmosphere between the troposphere and the stratosphere.
    The stratosphere is the second major atmospheric layer above the troposphere and tropopause extending in altitude from about 8 to 30 miles high. No weather occurs in the stratosphere.
    The ionosphere is defined as the layer of the Earth's atmosphere that is ionized by solar and cosmic radiation. It lies 75-1000 km above the Earth.

    By following these information option 3 is correct.

  • Question 10
    1 / -0
    The instrument used for measuring air pressure is called
    Solution
    A barometer is a scientific instrument used in meteorology to measure atmospheric pressure. A simple barometer consists of a long glass tube (closed at one end, open at the other) filled with mercury and turned upside down into a container of mercury.
  • Question 11
    1 / -0
    Less dew is formed on cloudy nights because
    Solution
    Cloudy nights are less likely to experience dew formation at the Earth's surface because radiation cooling is reduced. Wind will also reduce the chance of dew formation as it reduces the humidity (and therefore the dew point) of the air in contact with the ground.
  • Question 12
    1 / -0
    The instrument used for measuring relative humidity in air is
    Solution
    Hygrometer, instrument used in meteorological science to measure the humidity, or amount of water vapour in the air. Several major types of hygrometers are used to measure humidity.
  • Question 13
    1 / -0
    Which of the following are forms of precipitation?
    1. Snow
    2. Dew
    3. Hail
    4. Fog
    Choose the correct answer from the codes given below:
    Solution
    The five main types of precipitation are rain, snow, hail, sleet, and freezing rain. So, Snow, Dew and Hail are the forms of precipitation.
  • Question 14
    1 / -0
    A sudden fall in the barometric reading indicates
    Solution
    Meteorologically, a drop in barometric reading means atmospheric pressure is falling.A barometer that is falling indicates that a low pressure system is moving in, and you can expect poorer weather i.e a storm . A storm is any disturbed state of an environment It may be marked by significant disruptions to normal conditions such as strong wind, tornadoes, hail, thunder and lightning , heavy precipitation etc.
  • Question 15
    1 / -0
    The formation of fog occurs when
    Solution
    Water vapor normally begins to condense on condensation nuclei such as dust, ice, and salt in order to form clouds. Fog, like its elevated cousin stratus, is a stable cloud deck which tends to form when a cool, stable air mass is trapped underneath a warm air mass. Fog normally occurs at a relative humidity near 100%.
  • Question 16
    1 / -0
    Hail storm occurs in summer season due to the formation of clouds called
    Solution
    Hail is a type of precipitation, or water in the atmosphere. Hail is formed when drops of water freeze together in the cold upper regions of thunderstorm clouds or Cumulonimbus clouds. Cumulonimbus is a dense, towering vertical cloud, forming from water vapor carried by powerful upward air currents.
  • Question 17
    1 / -0
    When moist air meets cold surface of earth, some of the water vapours condense on the particles of dust in air. It is called
    Solution
    Fog is a visible aerosol consisting of tiny water droplets or ice crystals suspended in the air at or near the Earth's surface. Fog can be considered a type of low-lying cloud, usually resembling stratus, and is heavily influenced by nearby bodies of water, topography, and wind conditions.
  • Question 18
    1 / -0
    Dew point is
    Solution
    Dew points indicate the amount moisture in the air. The higher the dew points, the higher the moisture content of the air at a given temperature. Dew point temperature is defined as the temperature to which the air would have to cool (at constant pressure and constant water vapor content) in order to reach saturation.
  • Question 19
    1 / -0
    Which type of rainfall leads to the formation of the windward and the leeward side?
    Solution
    In meteorology, leeward and windward are technical names for the directional sides of a mountain. The windward side is that side which faces the prevailing wind (upwind), whereas the leeward, or "lee" side, is the side sheltered from the wind by the mountain's very elevation (downwind).
    Orographic rainfall leads to the formation of the windward and the leeward side. It is a rain that is produced from the lifting of moist air over a mountain.
  • Question 20
    1 / -0
    The term 'rock' comprises
    Solution
    Rocks are composed of grains of minerals, which are homogeneous solids formed from a chemical compound arranged in an orderly manner.Rocks are formed when magma cools in the Earth's crust, or lava cools on the ground surface or the seabed.
  • Question 21
    1 / -0
    Which of the following is not a sedimentary rock?
    Solution
    Marble is not a sedimentary rock. Sedimentary rocks are one of the three types of rocks that is formed through solidification of layers of sediment. Rather, marble is a metamorphic rock that is formed from dolostone or limestone that is given tons of pressure and heat deep within the Earth.
  • Question 22
    1 / -0
    Which of the following metals is most abundant in the Earth's crust?
    Solution
    Aluminium is the most abundant metal in the Earth's crust, forming 8.23%. It is followed by iron which makes up 5.63% of the crust.
  • Question 23
    1 / -0
    In which type of rocks are metals like gold and copper mostly found?
    Solution

    Gold and copper mostly found in Igneous rock . This rock is one of the three main rock types, the others being sedimentary and metamorphic. Igneous rock is formed through the cooling and solidification of magma or lava.
  • Question 24
    1 / -0
    The instrument used for recording earthquake waves is
    Solution
    A seismograph is an instrument used to detect and record seismic waves. Seismic waves are propagating vibrations that carry energy from the source of an earthquake outward in all directions. They travel through the interior of the Earth and can be measured with sensitive detectors called seismographs.
