When wave come nears shore?
As a wave approaches the shore, its height increases and its speed decreases. This causes the wave's energy to be concentrated, leading to the wave breaking as it reaches shallow water near the shore. The breaking of the wave causes it to release its energy, creating the crashing sound associated with waves hitting the shore.
Near the shore tsunamis are higher or lower than average waves?
Tsunamis near the shore can be much higher than average waves because they are caused by underwater earthquakes or landslides, resulting in a massive displacement of water. This leads to a large wave with a much greater amplitude compared to normal waves.
Explain why coarse particles are likely to be deposited near shore while finer particles are deposited away from shore?
Coarse particles are heavier and settle quickly due to gravity, leading to deposition near the shore where energy from waves and currents is lower. Finer particles are lighter and are carried further offshore by the water flow before settling, resulting in deposition at greater distances from the shore.
Name and describe two kinds of currents that wave action can cause near shore?
Two kinds of currents that wave action can cause near shore are "Longshore Current", which is the overall direction and movement of the waves that strike the shore at an angle. The other kind of current is "Rip Currents", which are narrow streams of water that break through sandbars and drain rapidly back to sea.
How are tsunamis different from just big ocean waves?
An ordinary large wave has a short wavelength. When it reaches shore it will break wash in, and wash out in a matter of seconds. A tsunami wave behaves in a much different way. Such waves can be hundreds of miles in wavelength. When they reach shore, they do not behave as breaking waves, but rather come in as a massive surge of water, that continues to come in for several minutes.
What happen when waves come near the shore?
they break
When wave come near the shore they speed up?
Yes
What is the effect when the waves get to shallow water near the land?
When waves reach shallow water near the shore, their speed decreases while their height increases. This causes the waves to become steeper and eventually break against the shore, leading to the formation of surf.
Near shore crest shaped waves are called what?
Near shore crest shaped waves are called "plunging waves." These waves are characterized by a curling crest that breaks forward as the wave approaches the shore.
How do wave change as they apporch the shore?
As waves approach the shore, their height increases, and their speed decreases due to the interaction with the sea floor. The wave crests become steeper and eventually break as the waves approach the shallow water near the shore.
Why do waves come into shore?
Waves come into shore because they are generated by the wind. As the wind blows over the surface of the water, it transfers energy to the water molecules, creating ripples that eventually develop into waves. When these waves reach shallow water near the shore, they slow down and their height increases, causing them to break onto the beach.
When wave come nears shore?

The breaking of the wave causes it to release its energy, creating the crashing sound associated with waves hitting the shore.
Why do waves change direction when they are near shore?
Waves change direction near shore due to shoaling, which is the process of waves slowing down and increasing in height as they move into shallower water. This change in speed and height causes the waves to bend, aligning more parallel with the shoreline. The energy in the waves is also compressed which results in them breaking as they reach the shore.
Near the shore tsunamis are higher or lower than average waves?
Tsunamis near the shore can be much higher than average waves because they are caused by underwater earthquakes or landslides, resulting in a massive displacement of water. This leads to a large wave with a much greater amplitude compared to normal waves.
Why are large pebbles near shore?
Large pebbles near the shore are typically deposited by wave action. As waves hit the shore, they can pick up and transport larger rocks and pebbles, eventually depositing them closer to the shore. The size of the pebbles also helps to protect the shore from erosion by dissipating the energy of the waves.
Why do waves slow down close to the shore?
Waves slow down near the shore due to the decrease in water depth. As the waves approach shallower water, the wave energy is compressed, causing the wavelength to decrease and the wave height to increase. This change in wave characteristics ultimately leads to a decrease in wave speed.
What do waves change as they approach the shore?
As waves approach the shore, their wavelength decreases, causing the waves to grow in height. This phenomenon is known as wave shoaling. Additionally, wave velocity decreases as they enter shallower water near the shore.
