He has variously served as part-time faculty and taught petroleum engineering, English, geography, and geology at Louisiana State University LSU and taught geology at the University of Louisiana at Lafayette ULLwhere he was an adjunct full professor.

Geology review

Geology review Earth is the third planet from the Sun. We all live on Earth and it is currently the only planet where evidence of life exists.

As we discover more planets in other systems, we are finding a variety of worlds that might support life. However, we have no direct evidence for life anywhere else in the Universe. Of the eight planets in the Solar System, the Earth is one of the inner planets and is made of rock and metal.

You may also hear it described as a terrestrial planet as opposed to gas giants that include Jupiter and Saturn. Because of our distance from the Sun and our atmosphere, we exist in a very narrow temperature range that allows water to exist in solid, liquid, and gas states across the planet.

We live in the "Goldilock's Zone" or for those of you who will become scientists… the circumstellar habitable zone. Life has developed over billions of years because liquid water is present across our planet.

What else makes the Earth special? We have an atmosphere made up of nitrogen N2a relatively inert gas. The Plates and Mantle You will learn about the several layers of the planet in class, but you will spend your whole life on the lithosphere.

Earth processes

The lithosphere is the solid surface layer of the planet. It is a cool crust that surrounds the liquid and solid interior of Earth. You will probably spend your life above water which means you will live on a group of large landmasses or rock plates.

The rock plates that float across the surface of the Earth are called tectonic plates. Those plates float on the mantle, an area between the core and the crust. While the mantle is able to move in a very slow way, it is basically solid. It is a very special solid that is able to deform and move.

There are places where magma seeps to the surface, but the mantle is basically a plastic-like solid that can slowly swirl and move around the planet.

Liquid and Solid in the Core The core of the Earth has two distinct regions. There is a liquid outer core and a solid inner core.

Geology review

Both layers of the core are made of iron and nickel. The inner core is a giant furnace at super-high temperatures and pressures.

The flowing metal of the outer core helps create a dynamo effect. Dynamos can create large magnetic fields. In the case of the Earth, the magnetic field protects our planet from space, solar winds and solar radiation.

Scientists have also discovered that the pressure and temperature increase as you move towards the center of the planet. The outer core of the Earth has extreme temperatures and pressures that keep iron Fe and nickel Ni molecules in a liquid state.

Current evidence suggests that the inner core is 6, degrees Celsius 10, degrees Fahrenheit. The mantle has a range of to 4, degrees Celsius oF. Room temperature is about 23 degrees Celsius 74 oF. The Aurora borealis and Aurora australis are locations above the north and south poles where solar winds collide with the magnetosphere.

The colors of the aurora change when different types of molecules in the atmosphere are hit by the charged particles from the sun. Or search the sites for a specific topic.WAMAP is a web based mathematics assessment and course management platform.

Its use is provided free to Washington State public educational institution students and instructors. “Geology and Apologetics” is an online digital class for grades 8 to adult. The six classes are videos talking about scientific misconceptions that can confuse students and pull them away from a Christian Biblical perspective.

The International Journal of Coal Geology deals with fundamental and applied aspects of the geology and petrology of coal, oil/gas source rocks and shale gas resources.

The journal aims to advance the exploration, exploitation and utilization of these resources, and to stimulate environmental awareness as well as advancement of engineering for effective resource management.

The Himalayas, or Himalaya (/ ˌ h ɪ m ə ˈ l eɪ ə, h ɪ ˈ m ɑː l ə j ə /), form a mountain range in Asia, separating the plains of the Indian subcontinent from the Tibetan Plateau..

The Himalayan range has many of the Earth's highest peaks, including the highest, Mount Himalayas include over fifty mountains exceeding 7, metres (23, ft) in elevation, including ten of. What is science? Science is the concerted human effort to understand, or to understand better, the history of the natural world and how the natural world works, with observable physical evidence as the basis of that understanding is done through observation of natural phenomena, and/or through experimentation that tries to simulate natural processes under controlled conditions.

The progress of the earth sciences and the advancement of technologies associated with the understanding of our planet during the 's and 50's have led geologists to develop a new way of looking at the world and how it works.
