The Clearwater Craters

It’s more like an inland sea. It goes on for ever and ever amen, that’s how it looks. And you know what? Millions of years ago, before there were any human beings at all, that lake was full of water monsters. All different kinds of dinosaurs. They all died

Lake Huron is one of the most polluted fresh water lakes in America. It covers about 189 000 kilometers squared, and it is a component of the Lauretian Great Lakes. It drains to the Atlantic Ocean through St. Lawrence River. It receives an inflow from Lake Michigan and Lake Superior, while it drains to Lake Erie. The population surrounding the lake is about 3 million, which also contribute to its pollution (Ylvisaker 28).

The youngest of these rocks are dated at about 220,000 years ago. Rhyodacties and quartz latites in the modern caldera area extruded from about 320,000 years ago to 260,000 years ago, and then silica-rich rhyolites at Glass Mountain northeast of the caldera erupted from about 210,000 years ago to 80,000 years ago. The scattered distribution of the initial mafic eruptions indicates that they were erupted from the mantle, while the slightly younger domes and flows were from a deep-crustal source. The youngest rhyolite eruptions erupted at the northeast rim of the caldera at Glass Mountain and were the first activity of the silicic Long Valley magma chamber (Bailey, et. al., 1989).

The U-high freshman biology class designed an experiment to test the question; based on the number of micro invertebrates, what is the water quality of the U-high creek? On 9/22/14, the day of the experiment, the conditions were recorded at 10:05 AM. The temperature was 55 degrees with a 6 mph wind, and 62% humidity. One of the observations of the creek is that there was some garbage and trash on the banks, although there was minimal amount. Another observation was that there was run-off leading into the creek from roads, nearby parking lots, and neighboring yards. There were about 40 small fish, only about 2-3 inches long swimming north against the current. The water was also very clear, and the bottom was clearly visible. Based on the observations

It began 2 million years ago, Canada and the upper U.S. were covered in glaciers. All the repeated melting and freezing of the glaciers created thousands of cavities in the Canadian Shield, which were filled with melted glacier water which created the Great Lakes (and many other rivers and lakes). In the west, there used to be a HUGE lake (Lake Bonneville) but it drained into the Pacific Ocean through rivers and dried out

Mimas and another Saturn moon, Rhea, have been called the most heavily cratered bodies in the Solar System. It is believed that the craters on Mimas have been around since the beginning of the Solar System. Mimas is so heavily cratered that new impacts will overwrite the old craters that were created in the past. There just is not a part of the Mimas that has not been pounded by impacts.

Alabama is divided into four main physical regions. First, the Coastal Plain dominates the southern half of the state. It is the home of the Black Belt, which contains rich, chalky soil, and consists mostly of lowlands and low ridges. Second, the Piedmont Plateau is situated just to the north in east-central Alabama. This area is known for its rolling hills and valleys, as well as Alabama’s highest elevation point—the Cheaha Mountain. Third, ridges and valleys surround the Piedmont Plateau to the north and west. These landforms run northeast-southwest, and extend as far south as Birmingham. Finally, the Appalachian Plateau makes up most of the northeast. Part of the Highland Rim and the floodplain of the Tennessee River cut into Alabama’s extreme

The impact of the bolide created what geologists call the “Exmore Crater,” which is thought to have been as large as the state of Rhode Island and as deep as the Grand Canyon (“Chesapeake Bay Geology”). The area was covered in Ice Age glacial sheets up until 18,000 years ago when climatic warming forced the sheets to melt and retreat, allowing new wildlife and plant species to appear. The melting water of the glacial sheets flooded into the Susquehanna, Potomac, James, and York rivers and eventually poured into the Atlantic Ocean, causing sea levels to rise. This rise in sea level, in turn, submerged the Susquehanna River Valley, and formed the rough outline of the present day Chesapeake Bay (”Bay

Skagit Herald report, Skagit Valley REACH (Recovery, Empowerment, Advocacy, Community and Hope) Center support people who suffer from history of mental illness and substance abuse. They are based on peer counseling, career support, crisis intervention classes, social gathering, and/or just safe place to come and stay. One of the program members at the center who is in recovering from addiction had a mental health crisis, suicide ideation. Her response was to get to REACH center right away because she knew the place can keep her safe. She states the center has been a life-saver. Now, she is in the process of becoming a certified peer counselor for the center. The center is a self-help recovery center for people with mental health and recovering from addiction. The center puts emphasis on Wellness, Recovery, Action Plan (WRAP) which is a group intervention for adult with mental illness. The plan teaches key concepts of recovery, helpful tools during crisis, post crisis plan, and assist in creating advance directives. (Demay, 2014).

Lake deposits are primarily fine-grained clay- and silt-size sediments. The most extensive area of lake deposits is in north- ern Ohio bordering Lake Erie. These deposits, and adjacent areas of wave-planed ground moraine, are the result of sedimentation and erosion by large lakes that occupied the Erie basin as Wisconsinan-age ice retreated into Canada. Other lake deposits accumulated in stream valleys whose outlets were temporarily dammed by ice or outwash. Many outwash-dammed lake deposits are present in southeastern Ohio far beyond the glacial boundary. Peat deposits are associated with many lake deposits and formed through the accu- mulation of partially decayed aquatic vegetation in oxygen-depleted, stagnant water.

Impact craters are geologic structures formed when a large meteorite, asteroid or comet smashes in to a planet or a satellite. Meteorites are small rocks in space that hit the earth's atmosphere at a high velocity. Throughout their history they have heavily bombarded all the inner bodies in our solar system. In this experiment we will use marbles as our meteorites, these will be free falling objects that will be used to copy an asteroid impact. The surfaces of the Moon, Mars and Mercury, where other geologic processes stopped millions of years ago, record this bombardment clearly. On the Earth, however, which has been

The five Great Lakes (Lake Erie. Lake Huron, Lake Michigan, Lake Ontario. And Lake Superior) in North America are the largest group of freshwater lakes in the world.

Quebec is the providence in Canada, covering nearly 600,000 square miles. The notable landmasses found within Quebec include the Canadian Shield and the Appalachian Mountains. The Encyclopedia of Britannica reveals that the Canadian Shield has ice-smoothed hills, and is the most massive area containing exposed Precambrian rock (Behiels). The Appalachian Mountains are the separating feature distinguishing the Quebec’s borders from Main, Vermont, and New Hampshire (“Quebec Mountains”). The St. Lawrence River flows southwest of Lake Ontario to the northeast. Attractions involving the river include the Québec-Lévis ferry, cruises, and strolls on the Promenade Samuel-De Champlain (Quebec).

The process formed a lake second only to the Great Lakes in terms of volume of water and length of shoreline.

It is best described as water evaporating into the atmosphere and continues to condense into the clouds. It will than fall back to earth as precipitation. This precipitation soaks down into the soil as a process called infiltration, where it joins the groundwater, or it will run off over the landscape to join surface water. The surface water may evaporate out of the lake and back into the atmosphere or the water will move through the soil towards the groundwater and be taken up by plants that will put it back into the atmosphere. This process will just keep continuing and continuing over and
