Vesuvius and Mount Tambora are stratovolcanoes. A stratovolcano is a tall‚ conical volcano that often reaches the height of 2500 meters. They are made up of one layer of hardened lava‚ tephra (often called block rocks or bombs)‚ and volcanic ash and are characterized by a step profile and periodic and explosive eruptions. The lava is highly viscous or thick‚ it cools and hardens quickly before spreading far. The magma is composed of rock that is acidic‚ and high in silica. Mount Vesuvius reaches the

punished. Hephaestus was mad‚ he had already been thrown off Olympus for being ugly‚ now he was yet again blamed for something out of his control. Hephaestus didn’t realize that his anger had vented down to earth‚ mountains were exploding and pouring out lava‚ thankfully out of range of causing any harm. He had created the first volcano. Regardless‚ Zeus was furious‚ he ordered Hephaestus to clean up the disaster. Hephaestus had no choice but to listen‚ unless he wanted to face Zeus’s wrath. The fire was

Geology a science that examines the earth‚ its form and composition‚ and the changes it has undergone and is undergoing involves the knowledge of what happened before and the events occurring within the atmosphere requires not only a study of the materials found on earth but an understanding of the various geologic processes aims to develop an understanding of the earth’s materials and how these materials were changed and modified through the action of natural forces over a period of time Geology

liquid-like. The surface is like this‚ because it is searching for any possible escape route to relieve some of the atmospheric pressure. Also‚ with the surface as liquid-like as it is‚ its surface is constantly refilling all impact craters with molten lava. This lava ’s contents are not exactly discovered yet‚ but scientists are led to the belief that it contains sulfur

These craters range in size up to many hundreds of kilometers‚ but the most enormous craters have been flooded by lava‚ and only parts of the outline are visible. The total area of the moon is 37 930 000 square kilometers. One of these craters found‚ is the Alfrancus C. It has a maximum diameter of 10 km and a maximum radius of 5km. It has an estimated depth of

Professor Radcliffe Geology 1 Lab Report December 10‚ 2012 Geology of the Caribbean Islands Have you ever wondered how the famous tropical land masses located in Central America‚ known as the Caribbean Islands‚ came to existence? Well geologists have dated some of the rocks in the islands such as‚ Cuba and Trinidad‚ as far back as the Jurassic time period. This means the rocks formed about 145-200 million years ago‚ therefore the eldest islands from the Caribbean date way back to the time

mantle is hotter than average causing ‘mantle plumes’ to rise to the bottom of the lithosphere‚ find a thin or weak part of the lithosphere‚ and breaks through. In the case of the Hawaiian islands‚ the hotspot is underneath an oceanic plate and the lava has built up until it is higher than the surface of the sea. These hotspots remain in the same place in relation to the mantle‚ but the plates move across the hotspots. The Pacific plate has moved across a hotspot in the ocean leaving the chain of

What is a hazard- volcanic hazards include tephra‚ lava‚ pyroclastic flows‚ volcanic bombs and seismic hazards include earthquake‚ tsunami‚ liquefaction‚ landslides 2. Human issues- proximity to lowland coast‚ ability to adapt to change‚ socioeconomic effects‚ impacts within a community‚ difference in rich and poor‚ urban and
