sub-disciplines of earth science (geology, meteorology, oceanography, and astronomy)? Know the definition of each of these. Geology is the study of Earth divided into two broad areas –Physical and historical. Physical Geology examines the materials comprising earth, Historical Geology is to understand the origin of earth. Meteorolgy is the study of the Atomosphere and the processes that produce weather and climates. Oceanography integrates chemistry, physics, geology, and biology. It includes the study

A Civil Action We live on the blue planet; a planet that is named after the abundant presence of water on its surface. So yes there is a lot of water but how much of that water is actually useful to us? Most of the water on Earth is deposited in seas and oceans i.e. it is salty. The human species cannot digest saltwater hence the only water that is useful to us is in the handful of lakes, ponds and under the ground surface. Thus our illusion of there being enough water for us to live on for generations

Homework 3 Solutions 1. What indirect evidence provides us with information about Earth’s interior? Many pieces of evidence provide information about Earth’s interior, including meteorites, volcanic rock inclusions from the mantle, and laboratory experiments; however, we gain the most insight about Earth’s interior from the study of the behavior of seismic waves. 2. How do we know that the Earth’s interior is layered? We know that Earth’s interior is layered because seismic waves (S and P

Next, how are the arches actually formed after the fins have been started. The arches and alcoves form when horizontal bedding planes in the rock fins are attacked by weathering and erosion. One major section of weakness is the contact between the Dewey Bridge and Slick Rock Members. The groundwater is slightly acidic and percolates along this contact point which dissolves the calcite cement releasing grains of sand and silt. Over time, the fin is breached and a small opening is created at the contact

The word pyrite is derived from a Greek word pyrites lithos meaning “the stone which strikes fire,” also portrays the ability of the mineral to spark fire if stroked against iron. (Pyrite). It also has a common name which depicts the ability of this mineral to fool inexperienced people by looking like gold on the river bed hence the nickname of this mineral is ”fools gold.” .”(Mineral Information.) The chemical formula for pyrite is FeS2 (Iron Sulfide.) (Plummer.) It contains 46.6% Fe (iron)

Wegener, published his theory that all the continents were once joined together in one large supercontinent, which was named Pangaea. Wegeners theory of continental drift combined information from several subject areas, examples include: maps, biology, geology and climatology. Be that as it may, specialists in those disciplines rejected his ideas partly because he was not regarded as an expert himself, but mainly because he could explain how solid continents had changed their position. Wegener could never
