birds. This shows that biological isolation is a major point of the uniqueness of the Australian environment. The Australian environment also has relative geological stability. The last volcanoes were active many years ago‚ and the last of the glaciers shrank and melted many years ago. We only had volcanoes and glaciers because of the separation of Pangaea therefore making the Continental Drift Theory. There is little geological activity to create or refresh fertile soils. The majority of Australia

The island of Oahu and the Big Island are formed from volcanoes with hot spots in the middle of the Pacific plates‚ as to why both islands have the same landscape such as mountains‚ and volcanoes. Another likeness is the location of the islands‚ both islands are part of the state Hawai’i and are two of the eight major Hawaiian islands. Furthermore‚ the two islands also share

Geographers are interested in locational aspects of Earth phenomena (can it be mapped?) * Physical geography involves natural phenomena * Human/cultural geography involves phenomena caused by inhabitants Many different fields of geography overlap one another.

Sulfur is a native element that is found commonly in salt domes in the gulf region of the U.S states not only is the element found their but is found also in active and extinctive volcanoes. It able to be extract commercially from pyrite once it mined. For domestic production about ninety percent is converted to Sulfuric acid. Our human body even needs sulfur to survive.

accordion‚ the tambora‚ the marimba‚ the güira‚ as well as the occasional alto saxophone‚ broke sound barriers as the dominant style in the early twentieth century in the Dominican Republic. The accordion is a box-shaped musical instrument of the aerophone family. It is used by expanding or compressing a bellows while pressing keys‚ causing pallets‚ to open‚ which allow air to flow across strips of brass or steel‚ called reeds‚ which then vibrate to produce sound inside the box. The tambora is a short

Grímsvötn volcano is located near the center of the Vatnajökull ice cap in central Iceland. At a height of 5658 feet‚ it has the highest eruption frequency of all the volcanoes in Iceland. Grímsvötn volcano has a complex of calderas‚ of about six by eight kilometers in area‚ and a subglacial caldera lake sustained by geothermal heat. A caldera‚ a large‚ circular depression at the summit of a volcano‚ is formed when magma is withdrawn or erupted from a shallow underground magma reservoir. The caldera
