Soil is one of the main elements in the environment‚ it covers most of the dry part of the Earth’s crust‚ and the content of the materials‚ including salts‚ it is very important for the green vegetation cover on earth. On the other hand soil is one of the main components of construction‚ study of soil in the workplace is one of the first steps in the beginning of the project‚ and the lack of knowledge of soil characteristics and types and how to deal with it may lead to the failure of projects in

My long-time enjoyment of earth science‚ especially when it included fossil activities‚ had me doing earth science activities for kids from the time my own children were little ones. So when my middle school asked me to pick something to teach for six weeks that I just enjoyed‚ this was the first thing that came to mind. It was set up to be more like a club than a class‚ so while there were definitely learning goals‚ the most important goal was to have fun and enjoy ourselves. I knew I should include

* Minerals are non-renewable resources because the amounts that exist are finite although most are very abundant. * Economically recoverable resources account for a tiny proportion of the total that exists. * The main limitations on mineral availability are the locations‚ chemical form and purity of the deposits‚ and the availability of technologies to exploit them. * Their exploitation is economically important but can cause environmental damage. Factors affecting the viability of

When most people hear the term fossil dating‚ two things come to mind‚ one being‚ “Is that what you’re grandparents do?” (Valls‚ biology class) and two‚ “what is that?”. By using either relative or radioactive dating methods‚ most geologists have the ability to tell how old a single fossil is. As always though‚ we are left with the question of which is better? Delve deeper to understand the comparisons and contrasts of Relative and Radiometric dating‚ as well as further information on both topics

Alfred Wegener started a proposal of continental drift that simply stated that there was once a supercontinent called Pangaea. He believed that 200 million years ago the continent began breaking into smaller continents which began the layout of where they lie now. Many people and geologists rejected Wegener?s idea especially the North American geologists due to most of his evidence to back his proposal up had been gathered from Southern continents. Evidence that Wegener had listed to support his

Kamerer‚ Wesley‚ Williston Basin This report was prepared at the request of Mr. Tom Moore of Indiana University of Pennsylvania. It presents a concise overview of the Williston Basin’s key aspects including location/extent‚ tectonic setting‚ stratigraphy and major oil and gas plays. The Williston Basin covers a large geographic area stretching west from North Dakota to Montana and north from South Dakota into Saskatchewan and Manitoba provinces of Canada. The boundaries of the basin are defined by

Have you ever wondered how you could compare continental drift‚ sea-floor spreading‚ and plate tectonics? Well there are actually plenty of ways to compare these three topics in earth science. You could compare these topics in similarities; continental drift and plate tectonics both start on the same basis of idea‚ that Earth’s lithosphere is made up of tectonic plates. You could also state some differences‚ such as continental drift occurs on all plate types‚ but sea-floor spreading only takes place

<center><i>The Fundamental Principles of Relative Dating</i></center><br><br>Relative dating involves placing events in their proper chronological sequence‚ that is‚ in the order of their occurrence (Dutch 1998). This type of dating tells us which geologic event happened first‚ but does not give an exact date to which something happened. There are several different methods that are used in relative dating. These are the fundamental methods that are used in the field by geologists ’ and earth scientists

The San Andreas Fault is an intense‚ significant geological feature that greatly affected the passionate study of earthquakes. The San Andreas Fault influenced the notable geological characteristics such as wealthy minerals and created rare‚ breath-taking sceneries. This catastrophic geological feature motivated scientists to learn more of its powers and what we can do to better prepare for it earthquakes. I chose this geological feature because it constantly changes and affects the reoccurrence

Marine and Lacustrine Deposits ORIGINS AND GEOTECHNICAL ISSUES Robert Bartus s2721227 | 4 104ENG Geotechnical Engineering Practice | August 19‚ 2012 1 The origins of soil deposits on the earth’s crust can reveal significant findings in the chemical and mechanical characteristics of the soils themselves. It is important to uncover such origins to find how and where such deposits may have formed over tens of thousands of years ago. Marine and Lacustrine deposits are two soil types that are commonly
