  1. The energy needed for the water cycle to occur comes from the _______
  2. Half of the sun's energy reaches Earth's surface, is absorbed by land and oceans, and then transformed into________

    a solar energy
    b light energy
    c heat energy
    heat energy
  3. The continuous movement of water from the oceans and other bodies of water, to the atmosphere, and back to Earth's surface is known as ________

    a the Coriolis effect
    b precipitation
    c the water cycle
    the water cycle
  4. Air will rise if it is warmer than the surrounding air. This transfer of hear energy through the atmosphere occurs because of ___________

    a convection
    b condensation
    c conduction
  5. Differences in Earth's temperature are due to the sun's uneven heating of the Earth's surface. This creates areas of high and low pressure. The movement of air from an area of high pressure to an area of low pressure is called ________

    a precipitation
    b wind
    c humidity
  6. Plants absorb water from the soil and move it through the plant. Excess water leaves the plant though opening in the leaves during a process called ________

    a precipitation
    b transpiration
    c condensation
  7. Clouds form in the atmosphere because warm air, containing water vapor rises, then ______

    a cools and condenses
    b warms up and condenses
    c warms up and evaporates
    cools and condenses
  8. When rain falls on saturated or impervious ground, it then flows downhill contributing to rivers and streams. What is this called?

    a condensation
    b precipitation
    c surface runoff
    surface runoff
  9. When precipitation remains in the shallow soil layer, then filters down to become ground water, the process is known as _______

    a suface runoff
    b infiltration
    c convection
  10. Land areas that are drained by streams and rivers, and are divided by ridges, are known as _________

    a watersheds
    b lakes
    c aquifers
  11. When cloud droplets or ice crystals grow heavy enough to fall through the air, the result is _______

    a condensation
    b evaporation
    c precipitation
  12. The condition of Earth's atmosphere, at a particular time and place, is known as its ______
  13. The average, year-after-year conditions of temperature, precipitation, winds, and clouds in an area is known as its________

    a climate
    b weather
    c seasons
  14. 70% of Earth's surface is made up of oceans. They absorb and store a lot of heat energy. Therefore, the temperature of the oceans affects ______

    a climate
    b global warming
    c seasons
  15. When a cold air mass overtakes a slow-moving warm air mass, big thunderstorms (in the summer) and snowfalls (in the winter) may occur. This is because _____

    B cold front passed over the area
  16. Large bodies of air that have similar temperature, humidity, and air pressure at any given height in the atmosphere are known as ________

    a storm surges
    b weather
    c air masses
    air masses
  17. Jet streams, embedded within the prevailing westerlies, generally push air masses across the U.S. from west to east. Jet streams are responsible for ________

    a major ocean currents
    b the hole in the ozone
    c the movement of major weather events
    the movement of major weather events
  18. When a warm air mass overtakes a cold air mass, it forms a(n) _____ which produces steady, long-lasting rains in the summer and steady snowfalls in the winter.

    a occluded front
    b warm front
    c cold front
    warm front
  19. When a cold air mass and a warm air mass meet and can't move, the result is a(n) ______

    a occluded front
    b warm front
    c stationary front
    stationary front
  20. When a warm air mass is caught between a cool air mass and an even colder air mass, and is cut off from the ground, it is called a(n) _______

    a stationary front
    b cold front
    c occluded front
    occluded front
  21. When climbing a high mountain, why do you get out of breath?

    a air pressure is greater
    b there is less oxygen in each cubic meter of air
    c the percentage of oxygen in the air decreases
    there is less oxygen in each cubic meter of air
  22. What is the atmosphere primarily composed of?

    a nitrogen, oxygen, and trace gases
    b oxygen, carbon dioxide, and trace gases
    c nitrogen, carbon dioxide, and trace gases
    nitrogen, oxygen, and trace gases
