(topographical sheet‚ scale 1:50) and their sizes were determined using one scale of the map and also information recorded at the site. Sample of the sediment that was found at locality one (1) were collected random‚ by the students taking up a piece of rock without looking. These were placed on a study board were the long and l short axis of the sediments were measured by the use of large ruler and tape measure then the samples were recorded. The velocity at these localities two and three were obtained

debris and carrying them to a new location. These processes happen through gravity‚ wind‚ ice and water. In the Tongariro Volcanic Centre‚ winds are an effective denudation agent because the mountain top gales are frequent and severe. Winds can transport and deposit debris. They carry with them fine silts and sand particles and depositing them downwind. Material that is not protected by matted roots of plants‚ like tussock‚ is eroded by the wind leaving the plant isolated. Winds also distribute ash

Coastal Erosion Coastal Erosion is a huge problem today and is causing our beaches to get smaller and smaller every year. Coastal erosion is also causing the coast lines to recede and therefore taking away space for which people build on. Even though coastal erosion causes issues it is also the effect of something‚ Humans! Nature has a way of keeping the world in balance‚ it creates things such as barrier islands and sand dunes to help protect against costal erosion. However‚ humans play a

millimetres per year • The Ebro delta dates back to the end of the last ice age it has constantly changed‚ with the 15th to 16th centuries being the periods of greatest growth for the Delta 2. Which man-induced phenomenon accelerated sediment built up in the Ebro Delta? • Building of Dunes (specifically in 1991) • Construction of walkways on Dunes to fight against erosion • Removal of infrastructure located on the shore that prevents the normal development

As geologists‚ we examine layers of sediment on the Earth’s surface to approximate the dates of past geologic time periods. Ah sediment as you know is material like sand‚ gravel‚ fossil fragments that is transported by natural processes like wind ‚ water flow or the movement of glaciers. So sediment is transported and then deposited and it forms layers on the Earth’s surface over time. We examine these layers to learn about different geologic time periods including when they began and ended. For

pieces can also hit other land forms‚ shaping their form as well. In the mountains‚ there is slow moving glacial erosion‚ occurring over the span of thousands of years to move huge chunks and boulders. Glacial ice picks up everything‚ including sediment and water‚ and its increasing size is directly proportional to the force of erosion. Glacial erosion is the most noticeable in glacial mountains‚ such as the Athabasca Ice fields. Coastal erosion‚ also thought of as erosion done by waves‚ is crucial

At Red Bluff‚ the Tumblagooda Sandstone in this section is different to the Tumblagooda Sandstone found at Natures Window‚ and thus‚ the deposition environment is different. Red Bluff was most likely deposited in a fluvial-intertidal environment (shallow waters) as indicated by the high abundance of skolithos trace fossils‚ skolithos generally reside in shallow waters (refer to notebook‚ page 58). The higher abundance of trace fossils in the upper section of the sandstone than the lower section suggests

The Oregon Coast Range is composed of accreted oceanic sediments. The oldest rocks were formed during the Paleocene to the middle of the Eocene era. The rocks are gently folded and have a slight westward dip. As we walked out onto the Jetty‚ you could see how the waves came in at a slight angle rather than directly at the coast. Most of the rocks (particularly the smaller hand held size rocks) were jagged and triangular looking. This told me that these rocks came from a relatively close proximity

BAY RIVER DELTA The Morant Bay River Delta was our first location on the geography trip This delta is known as an arcuate delta. It is 4000m in width. The delta is orientated in a north to south direction. This delta is made up of a mixture of sediments in sizes from sand to small boulders (sand‚ gravel‚ coble‚ small boulder).It was also noted that the delta is very mature because it had people living on it. Some features that were observed on the Morant bay river delta are: * Flood plain
