2 _________ 1. the force that pulls fresh water toward the ocean _________ 2. streams of water moving like rivers through the ocean _________ 3. the up-and-down movements on the surface of the ocean Gravity Currents Waves

3 _________ 4. the cause of most waves and surface currents _________ 5. regular changes in the water level of the ocean Wind Tides

4 Precipitation Condensation Evaporation Surface Water Ground Water

5 _______ 1. Only half of the earth is covered by water. _______ 2. Water can be either fresh water of salt water. _______ 3. Fresh water carries nutrients and minerals to the ocean. _______ 4. Germs are tiny plants and animals that live on or near the surface of the ocean. False True True False

The ocean floor has mountains, valleys, and plains. _______ 8. Surface currents can affect the climate of land that they are near. True False True True

7 The path water takes as it travels between the earth and the air is called ________________. The gravitational pull of the sun and the moon on the ocean cause __________. Underwater earthquakes, volcanoes, and landslides sometimes cause __________. the water cycle tides waves

8 The largest and deepest ocean is the ______________. The smallest and shallowest ocean is the ______________. Temperature changes and the amount of salt in the water control the _____________________. Pacific Ocean Arctic Ocean deep ocean currents

9 Why do tides happen in different places on the earth? Name two ways wind determines the size of waves. wind speed by the distance the wind blows how long the wind blows The earth is rotating as the moon pulls on the earth
