natural hole that forms in the Earth’s surface as a result of the chemical weathering of carbonate rocks like limestone‚ as well as salt beds or rocks that can be severely weathered as water runs through them. Sinkholes develop when sub-surface rock develops a hole or void due to erosion‚ gradually soil from above seeps to fill the void in the rock‚ creating an open area or void in the sub-surface soil (“Staff”). Chemical weathering and loose limestone soil are ingredients to a sinkhole‚ naturally

Mass Wasting Mass Wasting In our previous unit we learned about the rock cycle. Part of this cycle is the external processes we have come to know as weathering‚ mass wasting‚ and erosion. These processes occur near the surface of the Earth and are powered by the energy from the sun. In this essay I will talk about the process of mass wasting (Lutgens‚ Tarbuck‚ & Tasa‚ 2011). Under tremendous strain from gravity‚ mass wasting is the movement of soil and rocks being pulled down. Mass wasting evens

Weathering- is a process where rocks are physically broken down or chemically modified by climatic or biological elements. Works through 3 processes: physical weathering‚ chemical weathering and biological weathering. Physical weathering- is the breaking down of rocks into smaller fragments brought about by physical (mechanical) forces. Works through 4 processes: alternate expansion and contraction‚ frost action‚ pressure release and salt crystal growth. Alternate expansion and contraction- this

2 Chemical warfare What is Chemical Warfare: To understand chemical warfare you must first understand what a chemical agent is. A United Nations report from 1969 defines chemical warfare agents as " ... chemical substances‚ whether gaseous‚ liquid or solid‚ which might be employed because of their direct toxic effects on man‚ animals and plants ... ". This means basically that any chemical that is used to directly effect and harm a person‚ plant‚ or animal would be an act of chemical warfare

Explain how the processes of weathering‚ erosion‚ transportation and deposition have shaped New Zealand. New Zealand is an amazing Ever-changing land‚ full of natural wonders. But there is more to our country than this‚ much more‚ because our country is unique on Earth. Four and a half billion years have made it a country of extraordinary landforms‚ through four main processes. These processes are called weathering‚ erosion‚ transpiration and deposition. As well as our environment and physical shape

Chemical equations are the symbolic representations of chemical reactions that are made up of reactants and products. It is made up of the chemical formulas of the reactants and the chemical formula of the products. The reactants are the substances or chemicals that takes part in during a reaction and the products are the chemicals are the substances that result from the chemical reaction. Reactants are on the left side of the chemical equation and the products are on the right side of the chemical

down into very small particles by various processes such as weathering. There are two types of weathering: Physical Weathering and Chemical Weathering. Physical Weathering arises from the heating and cooling‚ the wetting and drying‚ and the freezing and thawing of the land. These actions cause alternate expansion and contraction of rocks which eventually cause the rocks to crack. Factors which play important role in physical weathering include: * Erosion by wind and water. * The action
