sedimentary rocks and metamorphic rocks. I. The first type is igneous rocks (from the Greek word for fire) which are formed from molten rock (magma) and lava. A. Formation 1.coming up of magma through cracks 2. forming a layer on surface or filling other cracks 3. cooling forming a very hard igneous rock 4. magma on the surface of the earth‚ lava _ basalt B. Importance 1. geologically important - showing characteristics of a specific tectonic environment 2. allowing tectonic reconstitutions

pockets. As these pockets of magma cool slowly underground‚ the magma becomes igneous rocks. Igneous rocks also form when volcanoes erupt‚ causing the magma to rise above the earths surface‚ above the earths surface magma is called lava. The rocks are formed as the lava cools. Sedimentary rocks are formed at the surface of the Earth‚ either in water or on land. They are layers of fragments of rocks‚ minerals‚ or animal or plant material. Most sedimentary rocks become cemented together by minerals

There are two types of volcanic flows pyroclastic and mud flows. Pyroclastic volcanoes occur when the amount of magma in the chamber collects and the pressure increases causing the volcano to erupt. Mud flows are kind of like pyroclastic accept the lava in the chamber doesn’t collect and cause an eruption it just flows out the top of the volcano. Mount Etna is located on the island of silicon‚

Most people are unfamiliar with the positives of Volcanoes. Volcanoes do cause destruction to people’s houses (and other things) but‚ the ash‚ rocks‚ lava‚ etc. improves the landscapes and the environment.

The volcanoes affect the land in a good way because it is helping to improve our environment/earth. Nowadays‚ people don’t see difference

To what extent can preparedness and planning mitigate the effects of volcanic hazards? (40 marks) Volcanic activity happens across the surface of the globe and naturally hazards occur too. A hazard is a situation that poses a level of threat to life‚ health‚ property‚ or environment. It is easy to locate volcanoes‚ but it is very difficult to predict exactly when activity will take place‚ particularly a major eruption‚ this makes it difficult to prepare or plan for one. There is a very big difference

Mountain ranges are usually segmented by highlands or mountain passes and valleys. •Volcanoes A volcano is an opening‚ or rupture‚ in the surface or crust of the Earth or a planetary mass object‚ which allows hot lava‚ volcanic ash and gases to escape from the magma chamber below the surface. Lava is a hot molten rock or magma that has erupted onto the Earth’s crust. Tephra refers to the airborne matter from a volcanic eruption.

in January 1973‚ the island of Heimaey was the focus of a fissure opening and releasing vast quantities of lava and ash were erupted. As Iceland is a relatively rich country‚ it had the resources to evacuate the nearby port town of Vestmannaeyjar (population 5‚300) in under 7 hours. Furthermore‚ the state had the resources to pump water onto the lava flows‚ solidifying up to 20‚000m3 of lava every hour. This prevented much of the town from being completely destroyed. This shows that in rich countries

population of Kauai is a large amount of not only citizens‚ but vacationers too. Most of the tourism occurs at volcano national parks‚ memorials‚ pearl harbor‚ Napali coast‚ secluded beaches‚ and canyon state parks. The Napali coast is a stretch of black lava shores‚ and is one of the most visited sites in Kauai. The volcano state parks would be cool to visit because they were how Kauai‚ and the other islands of Hawaii‚ formed to begin with. Waimea Canyon is also
