Why are the waves higher at night?

Light and heat from the sun causes the water to warm up and evaporate causing air currents which in turn changes the frequency of the waves. The divergence of heat absorption of the land and the ocean courses a temperature difference which in turn causes large masses of air to flow and change the wave size and frequency. At night when the temperature somewhat equalizes the wind dies down the waves mellow out and the frequency changes. Now by earth standards these are local effects. You need to study the major air currents and the colories effect of the earth spinning has on global wave currents and air flow

HOW DOES GRAVITY ATTRACT?
Anything with mass literally bends the fabric of space around it (see picture), obviously the amount of bending that happens depends on mass of the object. However this means that anything in orbit is much like a penny spinning down a spiral well (but obviously it never loses energy as there are no resistive forces, so it stays at the same level of the well forever). And if you drop an apple (excuse the pun) the falling of it down to earth is like it rolling directly down a well. This is the currently accepted theory of what gravity “is” in effect. If you see the picture the orbiting object is spinning around the “well” created by the object with larger mass.

WHY ARE THINGS DIFFERENT COLOURS?

Well as you probably know our retinas detect electromagnetic radiation in the form of visible light, which is interpreted by our brain to form the picture we see, but that doesn’t explain why my laptop is red and the grass is green…? Well there’s quite a lot more to it than this, but to summarize, the matter of different things will be made up differently, with different atoms and different compounds constituting them. The object you’re looking at will absorb every wavelength of visible light in the spectrum, and re-emit only red (if it is red) for example. But in real life almost everything will absorb some of everything, and reflect some of everything, just a red object will emit predominantly red.
