Lecture 1: Introduction Geology - the study of the Earth‚ the processes that shape it‚ and the resources that could be obtained from it. Main branches Physical Geology - deals with the materials that comprise the Earth and the processes that affect it (e.g.‚ Volcanology‚ Seismology‚ Environmental Geology‚ Engineering Geology‚ Mining Geology‚ Petroleum Geology‚ Mineralogy‚ Petrology‚ Geomorphology‚ Geophysics‚ Geochemistry‚ Planetary Geology) Historical Geology - the study of the origin and

Heat: a form of energy Heat In physics and chemistry‚ heat is energy transferred from one body to another by thermal interactions.[1][2] The transfer of energy can occur in a variety of ways‚ among them conduction‚[3] radiation‚[4] and convection. Heat is not a property of a system or body‚ but instead is always associated with a process of some kind‚ and is synonymous with heat flow and heat transfer. Heat flow from hotter to colder systems occurs spontaneously‚ and is always accompanied by an

CFD PROJECT REPORT Submitted by Sai Yashwanth M IMPACT OF AERODYNAMICS ON AUTOMOBILES INTRODUCTION Aerodynamic forces are caused by the relative motion of automobiles with air and they cause: Drag (resistance to forward motion) Lift / down force (come into play during cornering and acceleration) Lateral forces (comes into play during cornering) Moments in roll‚ pitch and yaw As a result these factors have to be taken into consideration during automobile design.

THE FIRST PART OF THE SEMESTER (11 chapters) – main ideas only: Examples of main ideas are: The Earth – origin of Earth‚ oceans‚ life; the Earth’s internal layers… know physical concepts such as energy (kinetic‚ heat)‚ density‚ convection‚ bioaccumulation‚ biodegradation‚ photo-degradation‚ diffusion… Plate Tectonics – major Plate Tectonic principles; What are the 3 plate boundaries and their driving mechanisms? Where are trenches?... What are hot spots? What is our plate boundary

Equatorial The equatorial‚ hot‚ wet‚ climate is found between 5 degrees north and 10 degrees south of the equator. The temperature of the equatorial regions is hot throughout the year‚ with a very low temperature range usually of less than 3 degrees Celsius. Due to the heat in the equatorial belt mornings are bright and sunny. This causes evaporation and conventional air currents are set up‚ followed by heavy down pours of convectional rain. The amount of rainfall recorded in one afternoon may

Gothic Fiction In Victorian times there was a lot of controversy between the theories of superstition and science. There was a very public argument between the two‚ both enforcing different ideas about different aspects of life. The reason for this was because Charles Darwin had come up with the theory of evolution and had gone against all beliefs in religion and in God. Many people disagreed with his theories and idea’s and still chose to believe God created the world and everything on it. Both
