Convergent Plate Boundaries Convergent plate boundaries are locations where lithospheric plates are moving towards one another. The plate collisions that occur in these areas can produce earthquakes‚ volcanic activity and crustal deformation. Convergent Plate Boundary – Oceanic-Continental: When continental and oceanic plates collide the thinner and more dense oceanic plate is overridden by the thicker and less dense continental plate. The oceanic plate is forced down into the mantle in a process

The geology of carboniferous of the Midland Valley of Scotland Research Aims This essay will cover the basic geology of the Midland Valley‚ the changes in structure and volcano activities during the carboniferous period. General introduction of the Midland Valley The carboniferous is a period between 290 and 360 million years ago(Ref 1‚p.8‚Scotland Through Time). The Midland Valley was covered with lots of rainforest and numerous of coral reefs flourished in the tropical seas. Volcanos eruptions

Through the years humans have evolved beyond our expectations‚ while this is exciting we have caused damage and deterioration to our environment. From the air we breathe to the water we drink and the animals we consume‚ the environment is constantly being affected. First the very stuff we breathe

designed to impact on a rock particle placed between a fixed and a moving plate (jaw). The faces of the plates are made of hardened steel. Both plates could be flat or the fixed plate flat and the moving plate convex. The surfaces of both plates could be plain or corrugated. The moving plate applies the force of impact on the particles held against the stationary plate. Both plates are bolted on to a heavy block. The moving plate is pivoted at the top end (Blate crusher) or at the bottom end (Dodge-type

earths crust. As it moved along the crust‚ friction caused the plates to move. These convection currents beneath the earths surface forced the Australian plate to collide with the Pacific plate. Along this plate boundary‚ the pacific plate was being subducted underneath the Australian plate- which held the North Island of New Zealand. This made the Australian plate near the boundary buckle and bend as it pressed up against the Pacific plate. The limestone that was formed on the seabed was then forced

The mouth-watering aroma flooded my nose as I entered a room full of patrons and food. I was mesmerized by the atmosphere of the restaurant. The sound of the music mixed with the clashing of utensils and plates‚ and the sizzling sound of food being cooked by professionals was all too familiar. It was here where my family had our very first high class dinner. As my parents were ordering from the menu‚ I was witnessing the chef preparing beef. He first placed the beef on a pan and poured

The structure of the earth The earth has three major parts-the land part or lithosphere‚ the water part or hydrosphere and the air part or atmostpere. The lithosphere is the surface on which you live . It is also the earth solid sphere consisting mainly of massive rocks. The massive rocks form large land masses called continent and small island groups . Different land form such as mountains‚hills‚valleys‚plateaus and plains make up the lithosphere. The hydrosphere include all water forms
