We exist because we all have a purpose, sometimes in life humans face challenges that contemplates past decisions and their future; they contemplate life. we exist to fulfill our dreams, without a dream, without a goal we can’t fulfill it. we exist from our mother womb, and born into a world of life. so to say “why do we exist” we exist to create dreams and goals. to fulfill them, to experience life.
Answer:
Option (4)
Explanation:
Tsunamis are usually defined as the large and extensive wave that occurs in the oceans and seas due to the occurrence of an earthquake below the oceans, underwater landscape and other strong volcanic explosions.
They are mostly initiated by earthquakes, and these types of disasters are unpredictable. The movement of seismic waves is responsible for the generation of tsunamis over the ocean water body. The occurrence of tsunamis is somewhat predictable, by observing the changes that occur in terms of the height of sea level. By making these observations, immediate warnings are given, and the coastal areas are vacated at the earliest.
These tsunamis produce larger or smaller waves depending on the magnitude of the earthquake.
Thus, the correct answer is option (4).
The barrier islands shelter and protect the mainland from the powerful forces of wind, waves, tides, currents and the ravages of storms and hurricanes. They shelter the estuaries that form behind the barriers.
Barrier islands form as waves repeatedly deposit sediment parallel to the shoreline. As wind and waves shift in keeping with weather styles and neighborhood geographic features, those islands constantly pass, erode, and grow. They can even disappear entirely.
Key Biscayne is a barrier island found at the bottom give up of a sequence of islands that stretches alongside the southeastern coast of Florida. Barrier islands are construct-united states of sand that shape alongside the coast of larger land bodies.
Barrier islands are critically crucial in mitigating ocean swells and different hurricane events for the water systems at the mainland aspect of the barrier island, in addition to defensive the coastline. This efficaciously creates a unique environment of exceedingly low strength, brackish water.
