How to Prevent Soil Erosion TERRACING Terrace farming is a farming method that makes use of a hill to create a multiplatform farm. There are severals steps known as andenes which are built into the side of a hill. The idea behind it is that any rain that falls and builds up on the andenes will overflow into another andene below‚ making the most out of the nutrients it provides.

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

ECOSYSTEMS AT RISK – CASE STUDY 2 PART 1: CORAL REEFS – OVERVIEW Coral reefs are often referred to as “the rainforests of the sea” because of they form some of the most diverse ecosystems on Earth. Its massive structure is formed from coral polyps (tiny animals that live in colonies) that support approximately 25% of all known marine species by providing essential habitats. Factors affecting reef development and survival include temperature‚ light‚ sedimentation and salinity of the water. Without

.................................33IntroductionThe aim of my internal assessment is to figure out‚ by testing my hypothesis‚ if human infrastructure (influence) affects the bio-diversity and pollutant intake of a rivera‚ and it ’s surroundings‚ ecosystem. In my hypothesis I state that yes‚ this will in fact affect the bio-diversity and the water will be more polluted in an area very obviously manipulated by humans. To test this‚ I have taken samples and collected data from ten locations‚ five in
