With 71% percent of the whole world being covered in water, it is no wonder that we as humans have a fascination with the Earth’s oceans and its tides. In fact, it’s even worthwhile to invest in knowledge of the causes and effects of tides and currents in regard to the planet we inhabit. First, we shall examine the causes of tides and currents and then explore the effects of those tides and currents on various subjects of interest.
At first glance, tides appear simple, but the complexity of them perplexed great scientific thinkers to extent of Galileo proposing a false theory. He theorized that the tides were controlled by the earth’s daily and annual revolutions , proposing that parts of the earth moved faster than others causing the earth’s water to slosh about similar to a barrel of freshwater on a barge that suddenly jerks and turns. He was later proven wrong and we now know that the tides are caused by gravitational forces. In 1687, Sir Isaac Newton explained that ocean tides result from the gravitational attraction of the sun and moon on the oceans of the earth. Distance plays an important part in the cause of tides as well, more so than the magnitude of the gravitational attractive force. The effect of distance is seen in the relationship between the sun, the moon, and the Earth’s waters. The Moon controls the motion of tides despite being smaller, and thus having a lesser gravitational pull than the Sun, because of the Moon’s closeness to the earth compared to the…
