Across
  1. 4. an idealized cycle of processes undergone by rocks in the earth's crust, involving igneous intrusion, uplift, erosion, transportation, deposition as sedimentary rock, metamorphism, remelting, and further igneous intrusio
  2. 6. above-average sea-surface temperatures that periodically develop across the east-central equatorial Pacific
  3. 7. a tide just after a new or full moon, when there is the greatest difference between high and low water
  4. 10. the above-average sea-surface temperatures that periodically develop across the east-central equatorial Pacific
  5. 11. the temperature at which water vapor can condense
  6. 14. eclipse in which the sun is obscured by the moon
  7. 15. happens when the Moon passes between the Sun and Earth, but when it is at or near its farthest point from Earth
  8. 18. affects the process through which heat is trapped near Earth's surface by substances known as 'greenhouse gases.
  9. 19. measures the distance north or south of the equator
  10. 20. air pollution that reduces visibility
  11. 22. the gravity of the sun
  12. 24. any liquid or frozen water that forms in the atmosphere and falls back to the earth
Down
  1. 1. when heat moves from one object to another object through direct touch
  2. 2. waves that are created as a result of vibrations between an electric field and a magnetic field
  3. 3. the cycle of processes by which water circulates between the earth's oceans, atmosphere, and land, involving precipitation as rain and snow, drainage in streams and rivers, and return to the atmosphere by evaporation and transpiration
  4. 5. an optical instrument designed to make distant objects appear nearer, containing an arrangement of lenses, or of curved mirrors and lenses, by which rays of light are collected and focused and the resulting image magnified.
  5. 8. the region of the earth's atmosphere above the stratosphere and below the thermosphere, between about 30 and 50 miles (50 and 80 km) in altitude
  6. 9. a high wispy white cloud usually of minute ice crystals formed at altitudes between about 20,000 and 40,000 feet (6,000 and 12,000 meters)
  7. 12. a line or column of light,heat,or electromagnetic radiation
  8. 13. displays yearly temperature and precipitation statistics for a particular location
  9. 14. a wall or embankment erected to prevent the sea from encroaching on or eroding an area of land
  10. 16. relating to or involving volcanic processes
  11. 17. denoting or relating to rock that has undergone transformation by heat, pressure, or other natural agencies, e.g. in the folding of strata or the nearby intrusion of igneous rocks
  12. 21. that has formed from sediment deposited by water or air
  13. 23. a breeze blowing toward the sea from the land, especially at night, owing to the relative warmth of the sea
  14. 24. situated at or near, coming from, or relating to either of the earth's poles or the area inside the Arctic or Antarctic Circles
