Earth History (Geological Timeline) Lecturer Dr. Sameh Abu El Soud History of Early Geology Catastro‐phism Tries to explain the presence of everything on earth and their composition by catastrophes. E.g. A catastrophe happened to dinosaurs 80 million years ago. A comet fell on earth surface leading to volcanoes‚ leading to dust clouds in the atmosphere‚ preventing solar rays penetration ‚ the plants died and then the dinosaurs. Uniformi‐tarianism (James Hu on‚ late 1700s) ‐ He proposed that the

materials may move by falling‚ toppling‚ sliding‚ spreading‚ or flowing. Some landslides are rapid‚ occurring in seconds‚ whereas others may take hours‚ weeks‚ or even longer to develop. Causes of landslides Many factors contribute to slides‚ including geology‚ gravity‚ weather‚ groundwater‚ wave action‚ and human actions. Although landslides usually occur on steep slopes‚ they also can occur in areas of low relief. Landslides can occur as ground failure of river bluffs‚ cur and fill failures that may accompany

According to Wegener‚ a geologist stated that segments of the Earth has made continental drift true (possible) whilst other pieces of information supported that continental drift has happened and is happening. 1. Geological Similarity The geology in terms of rocks‚ plants and animals‚ ice-shapes‚ and the outline of the land matches. To begin with‚ the rocks in the eastern coastline of South America and the rocks in the western

Geophysics was not of my passion when I was young or rather I did not know what Geophysics is and when I grow-up and completed high school I began to know what Geology means. I then started study it and read more about it which inferred from my interest to know and discover the wealth that is available underground. Accordingly‚ I have decided to join the Faculty of Earth Science to learn and study the discipline and master it. I now have completed a B.Sc. at King Abdulaziz University in FALL 2010

Throughout the past few decades‚ there have been advancements in new techniques to help determine the age of the Earth. Currently scientific evidence believes that the Earth is between 4.5 and 4.6 billions years old. To help determine the age of the earth‚ radiometric dating

Introduction The Forest Hill Formation is a geological area that mainly stretches from west-central to southeastern Mississippi‚ but thins right at the border of and barely touches Clarke County‚ Alabama (Echols‚ et al.‚ 1893). Geologist Ephraim Nobel Lowe originally proposed the name Madison Sands for this formation‚ due to the fact that he had studied it in Madison County‚ Mississippi. The name was later changed to Forest Hill by Charles Wythe Cooke. The Forest Hill Formation overlies the Red

Continental Drift It takes a lot of courage to stand up for something you believe in‚ especially when faced with intense amounts of scrutiny and rejection from colleagues and peers alike. But this is exactly what Alfred Wegener experienced when he advanced the unthinkable thoughts that all continents were once upon a time‚ all part of one massive supercontinent. He battled through the adversity‚ and continued to collect sources and ideas that backed his thinking. The purpose of this paper is
