Unit 1 Test1 Seasons & the water Cycle

1. Quarter 1: 2013 Test Review Unit 1 Test1Seasons & the water Cycle

2. Beginning with fall, the order of the seasons is • Fall • Winter • Spring • Summer

3. What is the measurement of the tilt of the Earth on its axis? • 23.5

4. During evaporation, the following change occurs: • Liquid changes to gas • Water changes to water vapor

5. Weather is caused by • The uneven heating and cooling of the Earth.

6. Which of the steps in the water cycle requires heat from the sun? • Evaporation

7. What day is the summer solstice? • June 21

8. Name all 3 of Earth’s climate zones. • Tropical zone • Temperate zone • Polar zone

9. How long does it take for the Earth to complete a rotation? • 24 hours

10. What is the Water cycle’s effect on the Earth? • It recycles our water supply so that it is never used up.

11. The ‘buddies’ in the water cycle are • Transpiration & evaporation

12. During evaporation, the following change occurs: • Liquid changes to gas • Water changes to water vapor

13. Why does water vapor rise into the air? • It is lighter than the air.

14. Clouds are formed by • Condensation

15. Why does precipitation occur? • There isn’t enough room for all of the water in the clouds. • The water droplets in the clouds join together and because of their size and weight. • The causes the water to leave the clouds. • None of the above. • Clouds are formed by • Evaporation • Condensation • Precipitation • Transpiration • Why does water vapor rise into the air? • It is drawn to the sun. • It is pushed up by the heat. • It is lighter than the air. • None of the above. • During evaporation, the following change occurs: • Liquid changes to gas • Gas changes to liquid • Water changes to water vapor • Both a &c • The ‘buddies’ in the water cycle are • Evaporation & condensation • Evaporation & precipitation • Condensation & transpiration • Transpiration & evaporation • What is the Water cycle’s effect on the Earth? • It makes us conserve water so that we don’t run out of water. • It gives us a new supply of water every day. • It recycles our water supply so that it is never used up. • None of the above. Which climate zone experiences one long warm and sunny season? • Tropical zone

16. Why does precipitation occur? • The water droplets in the clouds join together and because of their size and weight.

17. NAME THAT CLOUD!!!

18. Often block out the sun, and usually produce light to heavy continuous rain. • Stratus

19. Usually low clouds seen on an overcast day. • Stratus

20. Clouds usually associated with thunderstorms, and rise high into atmosphere & have an anvil shape. Cumulo-nimbus

21. Thin, wispy clouds, typically found at high altitudes. • Cirrus

22. Generally occur in fair weather and point in the direction of air movement at their elevation. • Cirrus

23. These are the ‘typical coloring book style’ clouds. • Cumulus

24. Fog can be considered a low version of this cloud in contact with the ground. • Stratus

25. Composed of ice crystals that originate from the freezing of super cooled water droplets. • Cirrus

26. Puffy clouds with distinct edges and usually a noticeable vertical (upward) development. • Cumulus

27. Vocabulary!!

28. Axis: • The imaginary line that runs through the Earth from the North pole to the South Pole.

29. Revolution: • The movement of the Earth in it’s orbit around the sun. It takes about 365 days, or one year.

30. Summer Solstice: • The day of the year when the Earth receives maximum amounts of daylight. There are more daylight hours on this day than any other day of the year.

31. Equator • The imaginary line of latitude that cuts the Earth into two equal hemispheres.

32. Rotation: • The movement of the Earth as it spins on it’s axis. Takes about 24 hours or one day.

33. Precipitation: • The process in the water cycle after condensation when the liquid water suspended in the atmosphere stick together and become to heavy. When the atmosphere can no longer hold the water it will fall back to the Earth as RAIN, SNOW, SLEET, or, HAIL.

34. Winter Solstice: • The day of the year when the Earth receives the MINIMUM amount of direct sunlight. This gives us the day with the least amount of daylight hours. • December 21

35. Run-off: • When the ground is too saturated to hold any more water, the excess water ‘runs-off’ to lower lying areas. • This helps to move ground water through the water cycle.

36. Evaporation: • Process in the water cycle when heat from the sun heats the surface of Earth’s water and turns it into a gas called water vapor. • Moves water through the water cycle by turning LIQUID water to a GAS. • Water to water vapor • Liquid to gas

37. Fall Equinox: • September 21 • This day receives equal amount of sunlight hours to darkness.

38. Water Cycle: • The recycling process of Earth’s water resource. • Water is changed from a liquid to a gas (water vapor) through evaporation, transpiration (evaporation from plant leaves) • Then as the water vapor rises (because it is lighter than air) and reaches cooler air, the water vapor is condensed back into a liquid (and clouds are formed). The water will remain suspended in the air until the molecules stick together and become to HEAVY for the atmosphere to hold. • It then fall back to the Earth as precipitation (rain, snow, sleet, or hail).

39. Condensation: • The process in the water cycle where water vapor cools in the atmosphere and is changed back into it’s liquid form. This is how clouds are formed. • The liquid water remains in the atmosphere as long as the atmosphere can hold it.

40. Latitude & Longitude • The grid system of imaginary lines running perpendicular to each other. • It purpose is to give a systematic, accurate, and effective means to describe locations on the Earth.

41. Spring Equinox: • March 21 This day of the year has equal amounts of daylight hours to darkness.

42. Transpiration: • The ‘buddy’ to EVAPORATION in the water cycle. • This is the process of water evaporating through the surface of leaves.
