Detailed explanation-1: -Waves on the ocean surface are usually formed by wind. When wind blows, it transfers the energy through friction.
Detailed explanation-2: -Surface currents in the ocean are driven by global wind systems that are fueled by energy from the Sun. Patterns of surface currents are determined by wind direction, Coriolis forces from the Earth’s rotation, and the position of landforms that interact with the currents.
Detailed explanation-3: -Movement of water caused by meteorological effects (winds and atmospheric pressure changes) are called surges. Surges are not regular like tides.
Detailed explanation-4: -Horizontal Currents They are currents that occur on the top layer of the ocean and are primarily driven by wind.
Detailed explanation-5: -A wave causes the water surface to move up and down in simple harmonic motion as the wave crests and troughs. The time for one complete cycle is the wave’s period T. The wave’s frequency will be f=1/T.
