Chapter 1: An Introduction to Geology What is geology‚ and what is the difference between physical and historical geology? Geology is the scientific study of the Earth and its major systems Physical Geology is the Study of the Earth’s composition. structure‚ and the processing that shape it Historical Geology is the Study of Earth’s history and the history of life With respect to why we study geology‚ in class I cited three areas of benefit to humanity where geologic knowledge is needed.

all. But yet‚ people show none. They have busy lives and don’t have time for "silly" things such as destructive volcanic eruptions. On top of that‚ they have all seen the movies in which people have effortlessly escaped the wrath of magma flow of "the rather gentle and atypical volcanoes in Hawaii." These people willingly‚ and sometimes unknowingly‚ make themselves easy prey for volcanic eruptions. But there is one group of people--people who have seen the horror that volcanoes wreak‚ people who have

Located in Greece‚ the volcano is in modern-day Santorini an island in the south of the Aegean Sea (Fig 1). Thera is part of the South Aegean Volcanic arc‚ which a consequence of the subduction of the

or may not survive. Shifting focus on natural selection‚ Darwin believes natural selection and change can happen to all species in the world as opposed to in individual species at certain times. From geological evidence through landforms‚ he concludes species and landforms may develop simultaneously‚ labeling this idea as parallel succession. However‚ he also argues species do not remain in their environment forever. He believes geological change‚ such as migration‚ may affect the rate of descent

features of a glacier can be extremely large or extremely small. As a glacier moves‚ its scours away material underneath it pulling up rocks‚ this is the material that is embedded in the ice at the base of a glacier. Though there are many landforms caused by glaciers but here are a few‚ cirque‚ crevasse‚ erratic‚ a kettle. A cirque is a bowl shaped depression carved out of a mountain by an alpine glacier. A crevasse is a deep‚ vertical crack that develops in the upper portion of glacier ice

Volcanic and Seismic events are major factors towards providing that plate techtonics theory is valid. Discuss the extent to which you agree with the statement. (40 marks) Throughout close analysing we can see patterns in the occurance of seismic and volcanic activity worlwide. These patterns can be used as clues to help discover why such events occur‚ and it is clear that both volcanic and seismic activity is most abundant on and around plate margins. However despite there being a clear link

Sinkholes are incredible destructive unpredictable natural disasters. Florida has many sinkhole occurrences‚ caused by its limestone soil weakening with dried up water pockets in it. Much like every other natural disaster‚ sinkholes do take lives. Sinkholes tend to most occur in the mid-Florida to Tampa area. Though sinkholes are not very talked about or are normal occurrences‚ they do happen and many people do not know what they are. A sinkhole is a natural hole that forms in the Earth’s

Yellowstone’s volcanic potential‚ however far-fetched‚ was intriguing and urged the viewer to wonder about the future of Yellowstone. 2. The ratio of drama to documentary in Supervolcano was probably 80:20. Although there was factual evidence presented in the film‚ it seems as though it was manipulated to fit the plotline‚ and did not actually coincide with any scientific theory. It could easily be construed that the normal fluctuations at Yellowstone are indicators of looming volcanic activity

erupt violently into the air. Rocks ripped loose from the inside of the volcano or torn apart by the gas may be shot into the air with the lava. These rocks are blown out of a volcano and are called volcanic bombs. Along with these bombs dust‚ ash‚ lava and cinder are released into the air. Volcanic activity is classified by how often a volcano erupts. A volcano may be active‚ dormant‚ or extinct. Active volcanoes erupt constantly. Dormant volcanoes are inactive‚ but not long enough to determine

Its name is Olympus Mons and it measures a whooping 600km (373 miles) wide and 21km (13 miles) high. * The object with the most volcanic activity in our solar system is Io‚ one of Jupiter’s
