Across
  1. 4. a rising current of warm air created by solar energy heating the ground
  2. 5. the material through which energy flows
  3. 7. the transfer of heat energy in a fluid (gas or liquid) by the actual movement of the particles in the fluid from one place to another
  4. 11. a kind of waves that can travel through empty space and do not need a medium. Light is an example.
  5. 13. the day-to-day pattern of temperature and precipitation in your local area
  6. 15. a blanket of air (mainly nitrogen and oxygen) and moisture that surrounds the earth
  7. 16. electromagnetic energy that comes from the sun
Down
  1. 1. gases like carbon dioxide, methane, and water vapour that exist in low concentrations in the atmosphere; these gases allow sunlight in but block outgoing heat
  2. 2. any material that absorbs radiant energy
  3. 3. the extent to which a given object reflects light from the sun
  4. 6. the layer closest to the earth’s surface, extending upwards to approximately 15 kilometres above the ground
  5. 8. energy: energy that travels by radiation, such as light
  6. 9. the transfer of heat energy, generally in solids, through the collision of atoms in the
  7. 10. weather conditions in an area that are averaged over many years
  8. 12. the transfer of energy by electromagnetic waves (which do not need a medium)
  9. 14. all the water in the earth system, including the water in oceans, lakes, rivers, and groundwater
