EESA06H3 Chapter Notes - Chapter 1: Mantle Convection, Engineering Geology, Space Debris
Document Summary
Chapter 1 introduction to physical geology & the environment. Pangea: large land mass (all the lands) Great amounts of time are required for most geological processes. Geology involves deep time (greater amounts of time) Some geological processes occur quickly (landslide/volcanic eruption) when stored energy is suddenly released. Rapidly to a geologist may mean few million years. Earth is estimated to be at least 4. 55 billion years old. Fossils in rocks indicate that complex forms of animal life have existed on. Humans have been here only about the last 3 million years. In the past, they spent most of their time in the field looking for signs of minerals (prospector) Location of geological resources is important, but skills of geoscientists are required. Geoscientists: modern geologists expanding into additional scientific fields. Geophysicists - learn more about nature of physical conditions on or under earth"s surface. Petroleum geologists search for oil and gas. Seismologists study how to measure and mitigate earthquake activity.
