rock is arranged in layers or not‚ and creates immense pressure that forces the rock apart. This continuous cycle of the build up of pressure and release of pressure (Dilatation) eventually causes sediments of the cliff to fall off. Abrasion‚ or Corrasion‚ happens when rocks and other pieces or sediment carried in suspension in the water is thrown at the cliff‚ thus braking off pieces of the cliff that can then be used to throw back at the cliff. This is particularly effective on exposed coastlines

The Grand Canyon: Geology The Grand Canyon‚ with its many layers of sediment‚ tells a story as old as 2 billion years. Chronologically‚ the layers fallow the Law of Superposition (youngest rocks on top‚ oldest on bottom). In toltal one would see 9 distinctive layers that give us evidence to how and what was going on millions of years ago. The first layer of sediment dating back 250 mil years ago existed during a time where the area was submerged in water. This is evident by its Kaibab limestone

This has caused irreversible damage to trees‚ birds and animals. While separating the sediment and mercury from the gold-yielding gravel deposits‚ small-scale miners who are less equipped than industrial miners‚ may ignore release of some mercury into the river. This mercury enters the food chain through aquatic animals and their predators. Highly poisonous compound ’cyanide’ is also used to separate gold from sediment and rock. In spite of all precautionary measures‚ it sometimes escapes into the surrounding

What is the Effect of the Colour of Light on the Rate of Photosynthesis? By Amelia Rowan‚ 12SDa Aim To discover whether the colour of the light source has any effect on the rate of photosynthesis of a sample of algae. Hypothesis It was predicted that the colour of the light source would have a very slight effect on the rate of photosynthesis. It was further predicted that when the sample was placed under the green light‚ the rate of photosynthesis would be the lowest. This hypothesis was arrived

Young Earth Creation Recently‚ new speculation has shown that mother earth may in fact not be 4.5 billion years old‚ as has been taught in schools for many generations. However‚ young earth creationist believe that the world is only approximately six thousand years old. According to the Christian Bible‚ if we were to follow the chronology of many of its books including Genesis‚ Exodus‚ Galatians and 1 Kings‚ we would gather a general timeline of when God created the universe and the Earth. No

from fossil remnants dating back to more than 3.5 billion years ago. Name the organism that forms Stromatolites and how they form them: Cyanobacteria form’s Stromatolites from the Cyanobacteria forming ‘colonies’‚ trapping sediments with their sticky surface. The sediment‚ now trapped‚ reacts with calcium carbonate in the water which creates limestone. The limestone starts to build up slowly; i.e. it can take a Stromatolite‚ approximately‚ 100 years to grow five cm until it reaches its full height

Mining companies would spray the mountains with high pressure water to make all the sediment come down and extract the gold from the sediment. This was not well regulated at the time and ended up having disastrous effects on the rivers in California. After the harm was done it was then outlawed in the state. This will most likely be the same thing that happens with

to be able to sustain and diversify the life that exists in these biomes. ‘Organisms that live in beach-estuary systems are phytoplankton‚ zooplankton and fish (in the water-column) and microphytobenthos‚ macrofauna and meiofauna which inhabit the sediment. The above mentioned organisms are the main organisms that drive ecosystem functioning in a beach-estuary system’. If the present environments had to disappear‚ there would be devastating effects not only in the biological sector but also the environmental
