4. Gulf Stream is a warm ocean current that flows across the Atlantic Ocean from the Gulf of Mexico into Florida and towards Europe.
5. A region's climate is determined by the movement of air, the movement of water currents, and latitude.
6. People who live in the Tropics usually have a hot climate.
7. El Ninos occur when cold winds from the east are weak.
8. The warming of the earth from the buildup of gases in the air is the greenhouse.

10. Subarctic climate, tundra climate, and ice cap climate are in high latitude climate region.
11. Groundwater is the type of water that can be tapped by wells.
12. Dense forests called rainforests are located along the equator.
13. Land areas in latitudes near the Equator are called the Tropics.
14. The dry area on the leeward side of the coastal mountains is called a rain shadow.

25. The weather pattern characterized by hot, humid, rainy summers, and short, mild winters is known as the humid subtropical climate. 
26. Almost all the water on the earth's surface is salt water.
27. Seventy percent (70%) of the earth's surface is covered by water.
28. Eighty percent (80%) of the earth's freshwater is frozen in glaciers.
29. Areas with humid subtropical climate have heaviest rainfall in summer.
