Many synthetic organic compounds such as plastic polymers, and a few natural ones, contain halogen atoms; these are known as halogenated compounds or organic halides. Chlorine is by far the most abundant of the halogens in seawater, and the only one needed in relatively large amounts (as chloride ions) by humans.
What is the difference between a tsunami and a tidal wave? Although both are sea waves, a tsunami and a tidal wave are two different and unrelated phenomena. A tidal wave is the wave motion of the tides. A tidal wave is a shallow water wave caused by the gravitational interactions between the Sun, Moon, and Earth.
A tsunami(or tidal wave) is a giant wave caused by a seaquake or eruption of sea volcanoes.After these disasters occur,water near the shore recedes as if there is a low tide.T â¦ hen,the water goes back as a wave at speeds of 800 miles per hour with a height reaching 30 meters.
