Galena Granite The science of Geology Geology is the science that pursues an underst in addition to ing of planet Earth Physical geology – examines the materials composing Earth in addition to seeks to underst in addition to the many processes that operate beneath in addition to upon its surface Historical geology – seeks an underst in addition to ing of the origin of Earth in addition to its development through time

The science of Geology Geology, people, in addition to the environment There are many important relationships between people in addition to the natural environment Some of the problems in addition to issues addressed by geology involve natural hazards, resources, world population growth, in addition to environmental issues El Salvador L in addition to slide 2001 Remotely Sensed Image Mt. Vesuvius in addition to Naples Italy. This is the volcano that buried Pompeii in addition to Herculaneum in A.D. 79.

The science of Geology Some historical notes about geology The nature of Earth has been a focus of study as long as centuries Catastrophism Developed in the mid-1600s. Great catastrophes shaped the l in addition to scape. Uni as long as mitarianism – Late 1700s. The present is the key to the past. Geologic time Geologists are now able to assign fairly accurate dates to events in Earth history Relative dating Relative dating means that dates are placed in their proper sequence or order without knowing their age in years Absolute dating With absolute dating we can determine the age of an object Fossil Evidence Fossil Fish from the Eocene age, found in Wyoming Extinct amphibian from the Permian age, found in Texas

Geologic time The magnitude of geologic time Involves vast amounts of times – millions or billions of years An appreciation as long as the magnitude of geologic time is important because many processes are very gradual The Geologic Time Scale Idealized Geologic Time Scale

The nature of scientific inquiry Science assumes the natural world is consistent in addition to predictable Goal of science is to discover patterns in nature in addition to use the knowledge to make predictions Scientists collect “facts” through observation in addition to measurements The nature of scientific inquiry How or why things happen are explained using a Hypothesis – a tentative (or untested) explanation Theory – a well-tested in addition to widely accepted view that the scientific community agrees best explains certain observable facts The nature of scientific inquiry Scientific methods Scientific method involves gathering facts through observations in addition to as long as mulation of hypotheses in addition to theories There is no fixed path that scientists follow that leads to scientific knowledge

A view of Earth Earth’s four spheres Hydrosphere Atmosphere Biosphere Solid Earth Earth as a system Earth is a dynamic planet with many interacting parts or spheres Parts of the Earth system are linked Characterized by processes that Vary on spatial scales from fractions of millimeter to thous in addition to s of kilometers Have time scales that range from milliseconds to billions of years Earth as a system The Earth system is powered by the Sun that drives external processes in the Atmosphere Hydrosphere At Earth’s surface

Earth as a system The Earth system is also powered by the Earth’s interior Heat remaining from the as long as mation in addition to heat that is continuously generated by radioactive decay powers the internal processes that produce volcanoes, earthquakes, in addition to mountains The rock cycle: part of the Earth system The loop that involves the processes by which one rock changes to another Illustrates the various processes in addition to paths as earth materials change both on the surface in addition to inside the Earth The Rock Cycle

The face of Earth Earth’s surface has two principal divisions Continents Ocean basins Significant difference between the continents in addition to ocean basins is their relative levels The face of Earth Continents Most prominent features are linear mountain belts Shields Ocean basins Ocean ridge system – the most prominent topographic feature on Earth Deep-ocean trenches Earth’s Physical Features
