Tides, Waves, and Currents

2. Caused by plates underneath the ocean slipping during an earthquake, or weather systems.
3. Phenomena caused by people, causing changes in the processes that propel water across the globe.
4. When perigee, perihelion, and the new or full moon occur at the same time.
5. A force which acts on the earth, pushing it away from the sun, and contributing to the tide-generating forces
6. This refers to when an area experiences 2 tides in the same day which are of the same height.
7. The maxima of a wave.
8. Fundamental force which influences currents.
11. When apogee, aphelion, and the first or third quarter moon occur at the same time.
13. powerful, narrow channels of fast moving water, kill ~100 people/year
15. This refers to when an area experiences 2 tides in the same day which are of different heights.
17. Seawater forms a crested shape and moves energy from one area to another.
18. When the moon is over the _______, we get semidiurnal tides.
20. _____ wave are caused by energy transfers from wind to the water via friction.
23. The discoloration of the ocean, caused by an explosion in the algae population.
26. This is a factor which affects riptides, that is, the direction from which wave-sources originate.

1. The influence of continents over the height of tides.
2. The largest waves on the planet, causes sea levels to rise and fall, caused by gravitational pull of moon and sun
4. A less destructive type of tsunami caused by weather systems.
5. A large movement of water in one general direction.

10. This refers to wherever the water meets land.
12. The sun’s _______ influences currents
14. If caught in a rip current, swim ________ to it.
16. When the moon is farthest away from the earth, the tide generating forces are weaker than average.
19. This refers to when a location only has 1 high tide and 1 low tide per day.
21. A type of current which joins with other currents of its type to form a riptide.
22. A wave’s _____ is influenced by wind speed, duration, and fetch
24. The minima of a wave.
25. Strong currents influence global climate patterns by moving _____ around the world.
26. Movement of air from hot regions to cold regions. Can influence waves, currents, and tides.
