Caribbean Geology The oldest land areas of the modern Caribbean are at the extreme ends of the arc of islands in Cuba and Trinidad. The Greater Antillean islands have all had a somewhat similar geological history but they differ from one another in the distribution‚ form and erosion patterns of the limestones deposited during several phases of submergence and uplift through the Tertiary period and Pleistocene. Apart from sporadic unions between islands now separated by shallow seas‚ as within the

2.1. Geology Jalpaiguri Districts almost entirely covered with alluvium expect that a narrow belt of hard rock is exposed along the northern border of the districts. The geological formations found in the districts are given below in the order of increasing antiquity. • Recent and Sub-Recent: Alluvium and other soils boulder and people beds. Miocene: - Siwaliks: - Sandstone with clay and lignite. Permian (Lower Gondwana):- Sandstone shape with Genes of Graphite coal. • Pre-cambnan (Buxa series):

Martin Orozco 11/7/12 Geologic Activity Throughout billions of years‚ Earth’s ground has been formed and transformed through a combination of geological events resulting in canyons‚ basins‚ mountains‚ etc. One of the oldest and most unique geological park is the The Grand Canyon. Today‚ the Grand Canyon is consider one of most fascinating natural wonders of the world due to its natural features and rock deposition that date back to millions of years ago. The Grand Canyon is a canyon divided

Your Name: Professor’s Name: Course Number: Date of Submission: Deep Ocean Mining Part 2 Deep ocean mining is an alternative to land mining in search of minerals such as copper‚ gold‚ manganese or cobalt among other minerals. The minerals on land are being depleted owing to the increasing demand for these minerals‚ and this makes the deep sea bed an alternative to the exploitation of minerals. The fact that the water

Assignment on “Brief History of Earth” Course: ENV 107 1 Brief History of Earth The history of the Earth concerns the development of the planet Earth from its formation to the present day. Nearly all branches of natural science have contributed to the understanding of the main events of the Earth ’s past. The age of Earth is approximately one-third of the age of the universe. An immense amount of biological and geological change has occurred in that time span. Earth formed around

Alfred Wegener(1880-1930) was the first man to propose the theory gplate tectonics.h He had got a Ph.D in astronomy from the University of Berlin‚ but he was also interested in the other science field such as geophysics‚ meteorology‚ and climatology. He also contributed to meteorology by establishing to track air circulation using balloon. In 1911‚ he read a paper that listed identical fossils of plants and animals found on opposite side of the Atlantic‚ and he looked for more of such organisms

On the Digermulen Peninsula‚ the succession starts with the classic Neoproterozoic glacial tillite of the Mortensnes Formation (Fig. 3). This tillite has traditionally been tentatively correlated by many workers (e.g.‚ Rice et al. 2011‚ and references therein) with the type ’Gaskiers’ glaciogenic succession in Newfoundland‚ which is between 584 and 582 Ma old‚ based on zircon U–Pb ages from intercalated ash beds (Bowring et al. 2002). The Mortensnes Formation is separated downwards from the ’Marinoan’

As geologists‚ we examine layers of sediment on the Earth’s surface to approximate the dates of past geologic time periods. Ah sediment as you know is material like sand‚ gravel‚ fossil fragments that is transported by natural processes like wind ‚ water flow or the movement of glaciers. So sediment is transported and then deposited and it forms layers on the Earth’s surface over time. We examine these layers to learn about different geologic time periods including when they began and ended. For

1) Would earthquakes of similar magnitudes in different populated regions of the Earth cause approximately the same levels of damage? In your discussions‚ consider both geologic and human-induced factors. The amount of damage caused by an Earthquake does not solely depend on the magnitude of the Earthquake. Factors such as population‚ geographic location‚ soil type‚ and the type of building material commonly used for construction in a region determine the extent of damage caused. If an Earthquake

Space Exploration What is it and why is it important? Space exploration is scientific studies using scientific equipment in space and anything about it. There are different reasons why space exploration is important. We could discover new resources from other planets or the moon‚ other planets can be could be used when something happens to the earth and we need another place to stay on. Occupation Space exploration is a well-paid job because it could be very dangerous. You also
