  • Sunlight shines almost directly onto the oceans in the tropics. What weather condition can be caused by the warming of surface ocean water in tropical regions?
    Hurricanes

  • Which system on Earth insulates the planet and protects it from solar radiation?
    Atmosphere

  • Most solar energy passes through the atmosphere and reaches Earth’s surface. Which process transfers energy from the sun to Earth’s atmosphere?
    radiation
  •  15
  • Earth's axis is tilted. Because of this, Earth's surface does not receive the same amount of sunlight everywhere. Which is a direct result of this uneven heating of Earth?
    global winds
  •  15
  • Solar energy does not warm Earth’s surface evenly. For example, during the day, land areas warm up faster than nearby bodies of water. How does this uneven warming affect the movement of air over land and water?
    sea breeze
  •  15
  • Although the Sun is millions of miles away, we are able to receive light and heat from it here on Earth. The Sun’s heat and light travel to Earth in the form of ultraviolet (UV) rays. Which type of heat transfer is this an example of?
    radiation
  •  15
  • Warm air moves from Earth's surface to the higher atmosphere where it cools and sinks is an example of?
    convection
  •  15
  • When energy from the Sun reaches Earth, the energy is not absorbed at the same rate by the air, the land, or the surface water. What does the uneven absorption rate of solar energy by air, land, and surface water cause to Earth?
    the change in global air circulations or wind
  •  15
  • Earth has hot, dry regions and cool, wet regions. How does convection contribute to the distribution of heat and moisture across Earth?
    causes air masses carrying water and energy as heat to rise and fall, all over Earth.

  • What factor contributes to the relatively high humidity levels that occur in the southeast United States?
    Warm, moist air from the Gulf of Mexico flows over this region

  • The transfer of heat is responsible for many of the events that occur on Earth. What event is most directly caused by radiation?
    the warming of Earth's surface
  •  15
  • The illustration shows layers of the atmosphere. Each layer blocks some radiation from outer space while allowing other radiation to pass through. Which layer of the atmosphere receives the least amount of radiation?
    Troposphere
  •  15
  • The Gulf Stream is a warm ocean current that flows north along the east coast of North America. How does the Gulf Stream affect the climate along the coast of the eastern United States?
    Its water warms the air, causing milder winter weather along the coast.

  • You have learned that the ozone layer protects Earth by absorbing some harmful ultraviolet radiation from the sun. Which layer of the atmosphere absorbs harmful X-rays and gamma rays from the sun?
    Thermosphere
  •  15
  • The atmosphere holds in the heat that comes through in the same way that a blanket holds in human body heat on a cold day. What will most likely happen if changes allow more heat to enter Earth's atmosphere but do not allow it to escape?
    Earth’s climate will become warmer.

  • Suppose it has been raining steadily for three days and there is danger of flooding. What type of weather system is the most likely cause?
    low pressure system
