     With the greeting “Aloha”, you will enjoy all varieties of activities and relaxation on passionate islands, Hawaii. You will get the opportunities of having dinner in the cruise, watching dolphins on the coast, stargazing in the tents. However, have you ever thought about how the naturally beautiful islands form? Hawaii, made of several islands, is a chain of volcanic islands on the North Pacific Ocean. The Hawaiian chain is a well-known island for the creation of volcanic islands. There are three orderly steps that formed the chain of Hawaii, it includes the influence of hot spot, the formation of islands, and the movement of the Pacific plates. (please see pic1)

     To begin with, Hawaiian hot spot is the key contributor to the emergence of a chain of islands. The hot spot is unique, owing to the fact that is it doesn’t exist in the boundaries of the plates. It occurs in the North Pacific because of the heat from the outer core. Rising through the process of convection, the heat radiates through the earth’s mantle, forming the bulges. Under the bulges, the hotness melts the solid rocks into liquid state, which is called as magma or lava. (please see pic2)

     Next, magma will lead to the creation of lava, and lava will cool down and form islands. Magma will reach the surface of the earth through magma plume. Once magma flows from the vent in a slow level of eruption, it will be called as lava. When heating the cooler water, lava hardens into the volcanic mountains underneath the ocean. As time flies, the accumulation of volcano form lands slowly and gently. Once the mountains emerge from the Pacific Ocean, the creation of islands is complete.  (please see pic3)

     Then, the chain of Hawaii stretches from northwest to southeast as a result of the movement of the Pacific plate. The plate is moving ahead toward northwest slowly, while the hotspot remains stationary; thus, it contributes to creation of a chain of Hawaii islands. The hotspot might move too, but there is no specific evidence. The volcano of Niihau and Kauai, the northwesternmost islands of the chain, has been existing for 5.5 million years. On the other hand, the main island of Hawaii, the biggest one, has started forming for merely 400,000 years. Hence, the hotspot is the cause of all of the Hawaiian mountains, no matter above the sea or not. As long as there is the hotspot and the moving plate, it will create new islands in the future. (please see pic4)

     The creation of Hawaiian chain is totally the masterpiece of mother nature. There are three chief steps to generate these gorgeous mountains. The hot spot generates heat; heat creates islands; and the unique Pacific plate causes a chain of islands. If you have the chance to explore Diamond Head, a Hawaiian mountain tourist spot, you can not only oversee the awe-inspiring views, but share the creation of the volcanic mountains to your partners.
