Tides Case Essay1)why the east cost has one high and one pocket-size heave a day but other parts of the world have two per day?The more or less common type of heave around the world is the semi-diurnal type this consists of two high and two low tides per day. Semi-diurnal tides occur when water is not uniformly raised this may be due to ocean currents, contributory rivers and other out and in flowing systems. This results in water sloshing around, making the tide phases twice per day. The microscope slide off Florida however, has a diurnal type of tide, having only one low and one high tide per day. Diurnal tides occur when water is relatively trapped, resulting in a uniform movement resonating from the midriff which follows the lunar phases.2) How is it we are experiencing GLOBAL WARMING LA NINA? I am confused how both back tooth exist at the same time.The worlds temperature is increasing due to global warming. La Nia is brought upon by the abnormal self-possesseding o f the pacific Ocean. How can this two phenomena coexist? The farmings temperature is regulated by wind and ocean currents, evenly distributing the Earths heat. The increase in the Earths temperature is an added strain to this system, implying that the currents need to distribute more heat. In distributing this heat, some areas become abnormally cool while other become abnormally hot. Whaen the abnormally cool area falls upon the Pacific Ocean, La Nia then occurs.3)Is gravity the only cause of a brandish change in shape at the shoreline?Gravity plays an important part in determining what shape a wave takes as it approaches the shore. However, strong winds that hit the wave can also mould it, either making it roll, or making its top crumble altogether. Additional, the tide in effect near the shore can designate how high a wave is when approaching.SourceCalvert J.B.
