Soil Porosity and Permeability GEO 101 LAB – Earth Science July 26‚ 2014 Soil Porosity and Permeability The focus of week three’s lab in Earth Science is to figure out the porosity and permeability of four different soil types: gravel‚ sand‚ potting soil‚ and soil from my back yard. This lab is designed to look at the porosity and permeability of these four soil samples. Porosity is basically the measure of how much of the soil volume is open space. Permeability is the measurement of how long

Landforms by Erosion (erosion is the main process) * High-energy waves * Rocks that are easily eroded 1) Cliff and shore platforms Point : A cliff is a high‚ steep rock face along the coast. Explanation: A cliff is formed when waves repeatedly pound against a rocky coast Elaboration: This weakens the rock‚ causing the lines of weakness to form in the rock face * Over time‚ the waves erode the coast to cut a notch along the lines of weakness. * The notch may be further

Pamela Aragon TOK Essay 1 February 17‚ 2012 “Truth is that which the community ultimately settles down.” (Charles Pierce) The human race‚ ever since its existence began‚ has been seeking truth. Living in a limited spherical space has forced us to adapt to communities. This has involved accepting laws‚ social contracts‚ morals‚ values‚ and most importantly‚ communal knowledge. Our pursuit of knowledge has been modeled by different groups and their accepted beliefs. Every new piece of knowledge

Coastal Erosion Coastal Erosion is a huge problem today and is causing our beaches to get smaller and smaller every year. Coastal erosion is also causing the coast lines to recede and therefore taking away space for which people build on. Even though coastal erosion causes issues it is also the effect of something‚ Humans! Nature has a way of keeping the world in balance‚ it creates things such as barrier islands and sand dunes to help protect against costal erosion. However‚ humans play a

Community service is one of many ways to help the surrounding community and make society a better place. There are many different forms of community service which include volunteering at local hospitals‚ churches‚ fire stations‚ clinics‚ and schools as well as other public or private organization within the community. Each task preformed at any of these establishments may help improve not only the economy of the society but help the performance of the organization. The efforts put forth to better

How has erosion effect beaches in recent times? In recent decades erosion has become a major issue to beaches around Australia‚ since beaches are temporary features. There is always sand being removed and sand being added to them‚ often‚ they change drastically during the year‚ depending upon the frequency of storms. Eventually‚ a beach erodes because the supply of sand to the beach cannot keep up with the loss of sand to the sea. The Sand dunes and vegetation help to hold the sand in place when

Soil is an important natural resource that covers much of the earth’s land surface. All life on earth depends on the soil as a direct or indirect source of food. Plants are rooted in the soil and obtain nutrients (nourishing substances) from it. Animals get nutrients from plants or from animals that eat plants. Certain microbes in the soil cause dead organisms to decay‚ which helps return nutrients to the soil. In addition‚ many kinds of animals find shelter in the soil. Soil contains mineral

The soil is an important part of the landscape and contributes to determine the way in which natural vegetation‚ crops and human settlements are distributed on the territory. But the importance of the soil is mainly related to its double role as a reserve of nutritional elements and water and mechanical support (how would plants be able to stand upright if they did not have the soil to put their roots in?) for vegetation‚ leading to the creation of forests and protected areas.
