Moraine State Park
Moraine State Park is a Pennsylvania state park on in Brady, Clay, Franklin, Muddy Creek, and Worth townships in Butler County, Pennsylvania. The park includes a man-made lake, Lake Arthur, formed by impounding Muddy Creek, which is and is used for recreational purposes. The surrounding park is used for hiking, bicycling, group camping, picnicking, and hunting. Moraine State Park hosts the annual Regatta at Lake Arthur in August. The park was the location of the 1973 and 1977 National Scout Jamborees. Moraine State Park is at the intersection of Interstate 79 and U.S. Route 422 and shares a border with Jennings Environmental Education Center to the north. Moraine State Park was chosen by the Pennsylvania Department of Conservation and Natural Resources (DCNR) and its Bureau of State Parks as one of "25 Must-See Pennsylvania State Parks".

Bituminous Coal
Bituminous coal, or black coal, is a type of coal containing a tar-like substance called bitumen or asphalt. Its coloration can be black or sometimes dark brown; often there are well-defined bands of bright and dull material within the coal seam, seams. It is typically hard but friable. Its quality is Coal analysis#Coal classification by rank, ranked higher than lignite and sub-bituminous coal, but lesser than anthracite. It is the most abundant rank of coal, with deposits found around the world, often in rocks of Carboniferous age. Bituminous coal is formed from sub-bituminous coal that is buried deeply enough to be heated to or higher. Bituminous coal is used primarily for electrical power generation and in the steel industry. Bituminous coal suitable for smelting iron (''coking coal'' or ''metallurgical coal'') must be low in sulfur and phosphorus. It commands a higher price than other grades of bituminous coal (thermal coal) used for heating and power generation. Within the ...

Shale
Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of Clay mineral, clay minerals (hydrous aluminium phyllosilicates, e.g., Kaolinite, kaolin, aluminium, Al2Silicon, Si2Oxygen, O5(hydroxide, OH)4) and tiny fragments (silt-sized particles) of other minerals, especially quartz and calcite.Blatt, Harvey and Robert J. Tracy (1996) ''Petrology: Igneous, Sedimentary and Metamorphic'', 2nd ed., Freeman, pp. 281–292 Shale is characterized by its tendency to split into thin layers (Lamination (geology), laminae) less than one centimeter in thickness. This property is called ''Fissility (geology), fissility''. Shale is the most common sedimentary rock. The term ''shale'' is sometimes applied more broadly, as essentially a synonym for mudrock, rather than in the narrower sense of clay-rich fissile mudrock. Texture Shale typically exhibits varying degrees of fissility. Because of the parallel orientation of clay mineral flakes in shale, it breaks in ...

Limestone
Limestone is a type of carbonate rock, carbonate sedimentary rock which is the main source of the material Lime (material), lime. It is composed mostly of the minerals calcite and aragonite, which are different Polymorphism (materials science), crystal forms of calcium carbonate . Limestone forms when these minerals Precipitation (chemistry), precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly Dolomite (rock), dolomite, a closely related rock, which contains a high percentage of the mineral Dolomite (mine ...

Glacial Till
image:Geschiebemergel.JPG, Closeup of glacial till. Note that the larger grains (pebbles and gravel) in the till are completely surrounded by the matrix of finer material (silt and sand), and this characteristic, known as ''matrix support'', is diagnostic of till. image:Glacial till exposed in roadcut-750px.jpg, Glacial till with tufts of grass Till or glacial till is unsorted glacier, glacial sediment. Till is derived from the erosion and entrainment of material by the moving ice of a glacier. It is deposited some distance down-ice to form terminal, lateral, medial and ground moraines. Till is classified into primary deposits, laid down directly by glaciers, and secondary deposits, reworked by fluvial transport and other processes. Description Till is a form of '' glacial drift'', which is rock material transported by a glacier and deposited directly from the ice or from running water emerging from the ice. It is distinguished from other forms of drift in that it is dep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Farmer
A farmer is a person engaged in agriculture, raising living organisms for food or raw materials. The term usually applies to people who do some combination of raising field crops, orchards, vineyards, poultry, or other livestock. A farmer might own the farmland or might work as a laborer on land owned by others. In most developed economies, a "farmer" is usually a farm owner ( landowner), while employees of the farm are known as '' farm workers'' (or farmhands). However, in other older definitions a farmer was a person who promotes or improves the growth of plants, land, or crops or raises animals (as livestock or fish) by labor and attention. Over half a billion farmers are smallholders, most of whom are in developing countries and who economically support almost two billion people. Globally, women constitute more than 40% of agricultural employees. History Farming dates back as far as the Neolithic, being one of the defining characteristics of that era. By the Bronze ...

North Country Trail
The North Country Trail (NCT, officially designated the North Country National Scenic Trail) is a long-distance hiking trail in the Midwestern United States, Midwestern and Northeastern United States, Northeastern United States. The trail extends roughly from Lake Sakakawea State Park in North Dakota to the Appalachian Trail in Green Mountain National Forest in Vermont, passing through eight states along its route. As of 2023, most of the trail is in place, though about one-third of the distance consists of road walking; those segments are frequently evaluated for transfer to off-road segments on nearby public or private lands. The trail was designated a National Scenic Trail by the United States Congress in 1980, and became an official unit of the National Park System in 2023. The NCT is administered by the National Park Service, managed by federal, state, and local agencies, and built and maintained primarily by volunteers coordinated by the North Country Trail Association (N ...

Beaver Wars
The Beaver Wars (), also known as the Iroquois Wars or the French and Iroquois Wars (), were a series of conflicts fought intermittently during the 17th century in North America throughout the Saint Lawrence River valley in Canada and the Great Lakes region which pitted the Iroquois against the Hurons, northern Algonquian peoples, Algonquians and their French allies. As a result of this conflict, the Iroquois destroyed several confederacies and tribes through warfare: the Hurons or Wendat, Erie people, Erie, Neutral Nation, Neutral, Wenro, Petun, Susquehannock, Mohicans, Mohican and northern Algonquins whom they defeated and dispersed, some fleeing to neighbouring peoples and others assimilated, routed, or killed. The Iroquois sought to expand their territory to monopolize the fur trade with European markets. They originally were a confederacy of the Mohawk people, Mohawk, Oneida people, Oneida, Onondaga people, Onondaga, Cayuga people, Cayuga, and Seneca people, Seneca tribes in ...

Clay
Clay is a type of fine-grained natural soil material containing clay minerals (hydrous aluminium phyllosilicates, e.g. kaolinite, ). Most pure clay minerals are white or light-coloured, but natural clays show a variety of colours from impurities, such as a reddish or brownish colour from small amounts of iron oxide. Clays develop plasticity (physics), plasticity when wet but can be hardened through Pottery#Firing, firing. Clay is the longest-known ceramic material. Prehistoric humans discovered the useful properties of clay and used it for making pottery. Some of the earliest pottery shards have been radiocarbon dating, dated to around 14,000 BCE, and Clay tablet, clay tablets were the first known writing medium. Clay is used in many modern industrial processes, such as paper making, cement production, and chemical filtration, filtering. Between one-half and two-thirds of the world's population live or work in buildings made with clay, often baked into brick, as an essenti ...

Sand
Sand is a granular material composed of finely divided mineral particles. Sand has various compositions but is usually defined by its grain size. Sand grains are smaller than gravel and coarser than silt. Sand can also refer to a textural class of soil or soil type; i.e., a soil containing more than 85 percent sand-sized particles by mass. The composition of sand varies, depending on the local rock sources and conditions, but the most common constituent of sand in inland continental settings and non-tropical coastal settings is silica (silicon dioxide, or SiO2), usually in the form of quartz. Calcium carbonate is the second most common type of sand. One such example of this is aragonite, which has been created over the past 500million years by various forms of life, such as coral and shellfish. It is the primary form of sand apparent in areas where reefs have dominated the ecosystem for millions of years, as in the Caribbean. Somewhat more rarely, sand may be composed ...
