answer I will discuss the positive impacts of volcanic activity. These positive impacts are geothermal energy‚ tourism and fertile soils. The first positive impact I will discuss is geothermal energy. Geothermal energy is heat that is generated by the plumes of magma that rise from the earth’s core to the crust. This magma heats the rocks of the earth’s crust. Geothermal energy is used as a major source of energy in Iceland. Iceland is a volcanic island formed by tectonic forces along the Mid-Atlantic

Natural Bridge Cavern Tour This was my third trip to the Cavern in the last five years‚ but I believe this is the first time that I have taken the time to appreciate the time line that the rock formations truly represent. Our tour guide explained that the caverns were first explored and mapped in the 1960’s and have been under continual exploration and development since that time. According to the website it is the largest commercially operated cave system in Texas‚ though not the largest

Explain how each of the following landforms are formed including diagrams and annotated photographs. When a river runs over alternating layers of hard and soft rock‚ rapids and waterfalls may form Waterfalls A waterfall is a place where water flows over a vertical drop in the course of a stream or river. Landforms in upland regions are dominantly created by erosion processes‚ where land is worn away. Generally‚ the volume and discharge of rivers in upland regions tends

What causes a volcanic eruption? When a part of the earth’s upper mantle or lower crust melts‚ magma forms. A volcano is essentially an opening or a vent through which this magma and the dissolved gases it contains are discharged. Although there are several factors triggering a volcanic eruption‚ three predominate: the buoyancy of the magma‚ the pressure from the exsolved gases in the magma and the injection of a new batch of magma into an already filled magma chamber. What follows is a brief description

Undara Lava tubes consist of a lava field remaining from a massive volcanic eruption of Mt Undara which occurred 190‚000 years ago. During the Cenozoic‚ there was wide spread igneous activity in Eastern Australia. Volcanism commenced in the late Cretaceous (approximately 70 Ma) and continued through the Cenozoic. The cenozoic is the current geological era. It began 66 million years ago and continues today. About 23.3 km³ of lava flowed from the Mt Undara volcano at an estimated rate of 1000 m³ a

part of the world heritage site (the Jurassic Coast)‚ from Old Harry Rocks to St Oswald’s Bay Discordant Coast - the structure and alignment of these rocks have a significant effect on the landforms produced. This is a discordant coast where the geological sequence has produced distinctive coastal landforms. At Old Harry/Ballard Point and at Durlston Head are outcrops of rocks resistant to erosion. The chalk escarpment which bends from St Oswald’s Bay eastwards to Old Harry increases in width
