What are the 4 main factors that affect the size of a wave?
A number of factors affect the size of waves. These include wind speed, duration, water depth, distance of wind travel over open water or fetch, direction of tide, speed of tide, etc. Higher wind speeds result in bigger waves and smaller speeds result in relatively smaller waves.
What causes huge waves in the sea?
Waves on the ocean surface are usually formed by wind. When wind blows, it transfers the energy through friction. The faster the wind, the longer it blows, or the farther it can blow uninterrupted, the bigger the waves. … The largest waves occur where there are big expanses of open water that wind can affect.
How are tides formed?
Tides are very long waves that move across the oceans. They are caused by the gravitational forces exerted on the earth by the moon, and to a lesser extent, the sun. … Because the gravitational pull of the moon is weaker on the far side of the Earth, inertia wins, the ocean bulges out and high tide occurs.What is worse a tidal wave or tsunami?
Strong tides have the potential to cause damage to the houses on the beach and can result in flooding. Tsunamis can have wavelengths of up to 200 kilometres and can travel over 800 kilometres per hour. When tsunamis approach shallow water near land masses, the speed decreases, and the amplitude increases very rapidly.Where do most tsunamis occur?
the Pacific Ocean
The largest number of earthquakes occur around the rim of the Pacific Ocean associated with a series of volcanoes and deep-ocean trenches known as the “Ring of Fire”. As a result, the largest source region for tsunamis is in the Pacific Ocean with 71% of all occurrences.
Can you swim under a tsunami?
“A person will be just swept up in it and carried along as debris; there’s no swimming out of a tsunami,” Garrison-Laney says. “There’s so much debris in the water that you’ll probably get crushed.”Which wave is carrying the most energy?
1 Answer
- Gamma( γ ) radiation has the greatest energy.
- This is because γ -radiation has the highest frequency.
- Energy α frequency.
What is the most important source of electromagnetic waves on earth?
Answer 1: The most obvious source of electromagnetic energy and radiation is the sun. The sun provides the initial energy source for much of the remote sensing of the Earth surface. The remote sensing device that we humans use to detect radiation from the sun is our eyes.
Which of the waves is carrying the greatest amount of energy?
gamma rays
