  1. Question 1

    What process generates energy in the Sun?

    • ANuclear fission
    • BNuclear fusion
    • CRadioactive decay
    • DChemical reactions
    Show answer

    Answer: B

    Nuclear fusion takes place at the core of the Sun, where hydrogen atoms fuse to form helium (Exercise A 21.1).

  2. Question 2

    The factor which primarily determines a planet's surface temperature:

    • Aits density
    • Bits orbital distance from the Sun
    • Cits gravitational field strength
    • Dthe number of moons it has
    Show answer

    Answer: B

    Orbital distance plays a vital role in determining the amount of solar energy received by each planet (Exercise A 21.2).

  3. Question 3

    What is the primary reason cyclones form over warm ocean waters?

    • AThe presence of strong winds
    • BThe high atmospheric pressure
    • CThe rising of warm, moist air creating low pressure
    • DThe gravitational pull of the moon
    Show answer

    Answer: C

    Air above warm water becomes less dense and rises, creating an area of low pressure (Exercise A 21.3).

  4. Question 4

    How does the Coriolis effect influence cyclones?

    • AIt causes cyclones to spin in opposite directions in different hemispheres
    • BIt strengthens cyclones over land
    • CIt prevents warm air from rising
    • DIt stops the formation of low-pressure areas
    Show answer

    Answer: A

    In the northern hemisphere the air spins anticlockwise and in the southern hemisphere clockwise (Exercise A 21.5).

  5. Question 5

    Information regarding environmental changes in space is collected by:

    • Asatellites orbiting around the Earth
    • Btelescopes on mountains only
    • Csubmarines
    • Dweather balloons only
    Show answer

    Answer: A

    Satellites orbiting the Earth collect data that help scientists protect the Earth.
