bedded flat and had layers. Its elevation was also less than 1,000 and the thickness was approximately 20. The newest rock in the area was the quaternary till that was on the top. This could have been deposited in the last million years. The sand sediments found…

widespread destruction of coral reefs are many, all acting simultaneously to contribute to the problem. Firstly, humans serve as a huge detriment to the coral reefs, boating, recreational diving, destructive fishing practices, and the runoff of sediments, nutrients, and contaminants from, industry, sewage, and agriculture are all known to be harmful to coral reefs. To further discuss the…

period of six days to ensure further safety and reduce the possible consumption of the contaminated materials. Groundwater is highly susceptible to the artificial components residing in crude oil and natural gas containing wells. Fracturing of the sediments creates openings that allow the fracking fluid to not only enter the targeted areas but travel into the surrounding areas as well, in cases of leaks. A study conducted by the United States Environmental Protection Agency released evidence in…

1. A breakwater has been constructed at Holdfast Shores because of some inconveniences and also because the area is for recreation. The breakwater was built because the sediment flow in the abrasion zone was being weathered away, it is clear why the breakwater was therefore constructed. If the erosion and weathering of the sediment flows continued the prime real estate and the area would begin to decay. It is a barrier placed offshore to absorb the impact and effects of ocean waves and release…

Our task was to figure out a way to stop, or decrease, a certain situation that is affecting the water quality of a particular body of water in our neighborhood. The body of water that we will be focusing on today, will be the Foxstone Creek in Vienna Virginia. Although there are many different problems that have occurred in this creek, the problem that we noticed that is the most impactful, is the amount of erosion on the creek. Erosion is the process by which the surface of earth is being…

Trimlines, which are rings of newly exposed rock, became noticeable around the inlet throughout the 2000s. Glaciers lift and carry sediments, rocks, and other fragments of the Earth’s surface and pile on the moraines. The moraine of the Columbia created an underwater ridge that prevented the sediments from moving past it. The moraine’s structure played an important role in the strength of the glacier before 1980. The glacier built its moraine over a period of time…

Introduction Postulated to be the result of either a long-runout landslide, or a structural pop-up, the Poverty Hills present a unique problem in the geologic community. Located on the western-most edge of the Basin and Range Province in eastern California (Fig.1), and within the Owens Valley basin, flanked by the Sierra Nevada and Inyo/White mountain ranges to the west and east, respectively. The hills are of particular interest as they represent an unusual combination of lithologies,…

the loss of natural habitats, the loss of real estate, and the loss of tax revenue. Loss of Natural Habitats Normally, wet lands keep pace with the gradual sea level rise through constant vegetative growth and a healthy sediment supply from up streams and tributaries. If sediment supply into the estuary system begin to lower, or sea level rise outpaces growth, wet lands can become submerged, and for all intensive purposes, reduced to open water areas. Unfortunately, Delaware is already losing…

The Elena Gallegos Open Space area sits near the base of the Sandia Mountains on a piedmont surface. This exercise was intended to gain insight into the mountain-front landforms of the Pino Embayment area. Through the use of surficial geological mapping and soil descriptions we were able to establish relative ages of geomorphic surfaces of the area and determine whether the area displayed qualities of alluvial fan and pediment surfaces. The geomorphic setting of the study area showed…

In the Panhandle of Florida, Okaloosa County is a place where the Earth Team volunteer program supports the USDA Natural Resources Conservation Service (NRCS) to assist the local service center activities. Nearly 25 years ago, District Conservationist Darryl Williams agreed to allow Linda Johnson to map the West Baker Gully project for emergency funding. This encounter began a lasting relationship between Williams and Johnson and he gained her as a member of the volunteer Earth Team. If you want…
