While it takes nature hundreds of years to make a few centimeters of topsoil‚ erosion can easily remove it. Without topsoil‚ people cannot raise crops for food.People know that without good soil they cannot raise agricultural crops. They also know from experience that wind and water can easily remove topsoil. Because of

Erosion caused by waves can be as subtle as the gentle wave constantly hitting the shoreline‚ or it can be a violent interaction between lake Michigan or inland lakes and the earth around them during ever during severe storms. In Michigan‚ there are primarily two types of material found on the shoreline. Bedrock‚ which is the harder of the two‚ known a consolidated substance and the effects of the water cause less erosion. Then there are the items like sand

The temperature of the Riparian zone affects the physical and the chemical properties of the water and largely influences the organisms affecting their feeding‚ metabolic rates and reproduction. It also affects how much oxygen can be dissolved in the water and how quickly the nutrients will be cycled through the water. Oxygen is better dissolved in cold water because gases are trapped by water molecules at colder temperatures. When temperatures rise‚ the molecules move around more‚ and gases‚ such

Determining Red 40 Concentrations Using Absorption with Beer’s Law Introduction I like color and enjoyed learning about wavelengths and the spectrum of light‚ so I considered incorporating something related to that into my Internal Assessment. We also had just used concentrations in our Group 4 Project‚ so when I found an experiment that dealt with both of these I thought it was a great idea. This experiment is not completely original; the basic concept has been used multiple times. It uses Beer’s
