Ocean Waves and Tides

For my post I'm going to tell you what causes ocean surface waves and ocean tides. I'll even going to explain many vocab words. Ocean tides is the rising and falling action of the ocean waters. Ocean tides occur when the moon and sun have a gravitational pull on the Earth. The moon's gravitational pull is stronger because it is closer to the Earth than the sun. The moon causes the Earth's ocean to bulge outward so the side facing the moon has a high tide and the side that does not face the moon has a low tide. The strongest tide is called the spring tide because the sun and moon are combined of the gravitational pull. The Neap tide is the lowest tide and it comes twice in a month, comes in the first and third quarters of the moon.      
Tides
Ocean surface waves occur by the wind so it turns into small ripples than into waves and the harder the wind the more powerful the wave is. A wavelength  is the distance between a the two points of the waves. The wave height is the height of the wave. Trough is the lowest part of the wave and the highest part of a wave is called the crest. Tsunami's are over sized waves caused by earthquakes, volcanic eruptions, and landslides beneath the ocean. The sea level is the horizontal plane of the sea or the level between high and low tide. Tidal range is the difference between the high tide and the low tide.
