The sun and moon cause ocean currents in several ways. First, the sun's heat causes the ocean water to expand and become less dense, which creates a rise in sea level. This rise in sea level creates a current that flows away from the equator and towards the poles.

Second, the moon's gravitational pull causes the oceans to bulge, creating tidal currents. These tidal currents can be very strong, and they cause the water to flow in circular patterns around the coasts.

Third, the moon's gravitational pull also causes the earth to rotate on its axis. This rotation creates a current called the Coriolis effect, which causes the ocean water to move in a circular pattern around the earth. This current helps to distribute heat and nutrients throughout the oceans.

Overall, the sun and moon cause ocean currents through their effects on sea level, tidal forces, and the earth's rotation.

Answer:

The sun warms up parts of the oceans. Warm waters rise just like warm air rises. So, as the warmer ocean waters begin to rise in a particular area, the cooler ocean waters from a different area will move in to replace the warmer ocean waters, and this creates our ocean currents.

What is equilibrium?

Equilibrium, in physics, the state of a system when neither the state of motion nor the state of internal energy tends to change over time. A simple mechanical body is in equilibrium when it experiences neither linear nor angular acceleration. This state will continue indefinitely unless disturbed by an external force. Equilibrium occurs for a single particle when the vector sum of all forces acting on the particle is zero. A rigid body (which by definition differs from a particle by its properties of extension) is in equilibrium when, in addition to the states listed above for particles, the vector sum of all torques acting on the body is equal to zero, Its state of rotational motion remains constant. An equilibrium is said to be stable when a small externally induced displacement from that state produces a force opposing the displacement tending to return the body or particle to the equilibrium state. Examples include weights suspended from springs or bricks placed on a flat surface. Equilibrium is unstable when small deviations produce forces that tend to increase the displacement. An example is the ball he bearing balanced on the edge of a razor.

In physics, wavelength is the spatial period of a periodic wave, i.e. the distance over which the wave shape repeats. This is the distance between consecutive corresponding points of the same phase in the wave. A crest, trough, or zero-crossing of two adjacent waves, characteristic of both traveling and standing waves, and other spatial wave patterns. The reciprocal of wavelength is called spatial frequency. Wavelength is usually represented by the Greek letter lambda (λ). The term wavelength is also sometimes applied to the sinusoidal envelope of modulated waves and waves formed by interference of modulated waves or multiple sinusoids.

Assuming a sine wave traveling with constant wave velocity, the wavelength is inversely proportional to the frequency of the wave. Higher frequency waves have shorter wavelengths and lower frequency waves have longer wavelengths.

Waves should be monochromatic - they should have a single wavelength. Suppose we have two sources emitting the same wave in phase.

This is the distance from the point to one source minus the distance from the point to the other source.
