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 encountered during soil exploration‚ both of which are primarily traced back to either glacial

Threats to Biodiversity: Habitat loss is mainly due to human population growth‚ industrialization and changes in the land use patterns‚ poaching of wild life and man wildlife conflicts. Man has begin to overuse or misuse most of these natural ecosystems. Due to unsustainable resource-use‚ once productive forests and grasslands have been turned into deserts and wastelands have increased all over world. Scientists have estimated that human activities are likely to eliminate approximately 10 million

The idea of conservation is when someone changes the shape of the substance in which it does not change the amount volume or mass. This is to see if children can think logically. In the experiment there is going to be two girls that are going to be tested over one 9 year and 13 year old. My prediction is that the 9 year old will not be able to conserve. The first experiment was using the 9 year girl. The experimenter first pour the same amount for each cup then ask the participant if there is the

Watershed Management and Soil Erosion Forests provide a buffer to filter water and to hold soil in place. They sustain water and soil resources through recycling nutrients. In watersheds where forests are degraded or destroyed‚ minimum flows decrease during the dry season‚ leading to drought‚ while peak floods and soil erosion increase during the wet season. Flooding along the Baram River in Sarawak has increased significantly since logging began‚ the major floods occurring in 1979 and 1981.168

Hydroponics: Growing Without Soil The science of growing plants without soil has been known and used for more than one-hundred years. The word “hydroponics”‚ however‚ is comparatively new. Dr. W.E. Gericke is usually given credit for coining the word‚ which translated from Greek‚ means “working water”. The famous hanging gardens of Babylon were probably on of the first attempts to grow plants hydroponically. The work of Dr. Greicke in the 1920’s and 1930’s
