Which type of wave makes for the best sailing on the ocean?
For boaters, long wave periods (e.g., 12 seconds) are better for sailing because it typically means most of the waves will be swells which means a smoother ride for small boats.
How do ocean waves form quizlet?
Ocean waves form when energy is transferred from a source such as wind to the ocean water. Most ocean waves form when there is energy or motion in the atmosphere that is transferred to the ocean’s surface. a series of waves that form when a large volume of ocean water is suddenly moved up or down.
How does a wave form quizlet?
How do waves form? Most waves form when winds blowing across the water’s surface transmit their energy to the water. Waves break against it, protecting the mainland from erosion.
How do longshore currents shape the land?
How do longshore currents shape the land? Longshore currents both tear down and build up the coastline by moving sand and sediments along the shore.
How big of a wave can a ship handle?
A rule of thumb is 1/3 of your boat length is what your boat can reasonably handle. Obviously, with seamanship, you can take more but the math is against you. Think a boat a boat balanced on a wave 50% of the length. The boat can go down at a 45% angle.
What constitutes rough seas?
If the sea or the weather at sea is rough, the weather is windy or stormy and there are very big waves.
What does an ocean wave need to form?
Waves are created by energy passing through water, causing it to move in a circular motion. Wind-driven waves, or surface waves, are created by the friction between wind and surface water. As wind blows across the surface of the ocean or a lake, the continual disturbance creates a wave crest.
Where do ocean waves get their energy?
Ocean waves get their energy mainly from the winds that blow across their surface. As the winds blow, friction builds up and causes the water to be…
Why have the beaches on Dauphin Island become smaller over the last few decades quizlet?
Why have the beaches on Dauphin Island become smaller over the last few decades? Sand dredged from the mouth of Mobile Bay has reduced the supply of sand to Dauphin Island. To survive, beaches need a constant supply of what? What two main driving forces produce a barrier island’s perceived migration?
What causes Longshores?
Longshore currents are generated when a “train” of waves reach the coastline and release bursts of energy. The speed at which waves approach the shore depends on sea floor and shoreline features and the depth of the water. Also, waves do not typically reach the beach perfectly parallel to the shoreline.
Why do waves hit the beach at an angle?
When waves approach the beach at an angle, the part of the wave that reaches shallow water earliest slows down the most, allowing the part of the wave that is farther offshore to catch up. In this way the wave is refracted (bent) so that it crashes on the shore more nearly parallel to the shore.
Can a wave flip a cruise ship?
Many experts agree that wind alone cannot cause a cruise ship to capsize, but waves caused by extreme wind feasibly could. A rogue wave could also cause a cruise ship to capsize.
