All Time Top Ten of Polemic for Geography

Interior Plains: The Interior Plains are a vast physiographic region that spreads across the Laurentian craton of central North America, extending along the east flank of the Rocky Mountains from the Gulf Coast region to the Arctic Beaufort Sea. In Canada, it encompasses the Canadian Prairies separating the Canadian Rockies from the Canadian Shield, as well as the Boreal Plains and Taiga Plains east of the Mackenzie and Richardson Mountains; while in the United States, it includes the Great Plains of the West/Midwest and
Weathering: Weathering is the deterioration of rocks, soils and minerals as well as wood and artificial materials through contact with water, atmospheric gases, and biological organisms. Weathering occurs in situ, and so is distinct from erosion, which involves the transport of rocks and minerals by agents such as water, ice, snow, wind, waves and gravity
Coastal plain: A coastal plain is flat, low-lying land adjacent to a sea coast. A fall line commonly marks the border between a coastal plain and a piedmont area. Some of the largest coastal plains are in Alaska and the southeastern United States. The Gulf Coastal Plain of North America extends northwards from the Gulf of Mexico along the Lower Mississippi River to the Ohio River, which is a distance of about 981 miles (1,579 km). The Atlantic Coastal Plain runs from the New York Bight to Florida
Arctic Lowlands: The Arctic Lands is a physiographic region in northern Canada. It is one of Canada's seven physiographic regions, which is divided into three divisions—the Innuitian region, Arctic Coastal Plain, and Arctic Lowlands
Old Harry Rocks: Old Harry Rocks are three chalk formations, including a stack and a stump, located at Handfast Point, on the Isle of Purbeck in Dorset, southern England. They mark the most eastern point of the Jurassic Coast, a UNESCO World Heritage Site
Great Lakes–St. Lawrence Lowlands: The Great Lakes-St. Lawrence Lowlands, or simply St. Lawrence Lowlands, is a physiographic region of Eastern Canada that comprises a section of southern Ontario bounded on the north by the Canadian Shield and by three of the Great Lakes — Lake Huron, Lake Erie and Lake Ontario — and extends along the St. Lawrence River to the Strait of Belle Isle and the Atlantic Ocean. The lowlands comprise three sub-regions that were created by intrusions from adjacent physiographic regions — the West Lowland
Trail of Tears: The Trail of Tears was a series of forced displacements of approximately 60,000 American Indians of the "Five Civilized Tribes" between 1830 and 1850 by the United States government. Part of the Indian removal, the ethnic cleansing was gradual, occurring over a period of nearly two decades. Members of the so-called "Five Civilized Tribes"—the Cherokee, Muscogee (Creek), Seminole, Chickasaw, and Choctaw nations —were forcibly removed from their ancestral homelands in the Southeastern United States to
Five themes of geography: The five themes of geography are an educational tool for teaching geography. The five themes were published in 1984 and widely adopted by teachers, textbook publishers, and curriculum designers in the United States. Most American geography and social studies classrooms have adopted the five themes in teaching practices, as they provide "an alternative to the detrimental, but unfortunately persistent, habit of teaching geography through rote memorization". They are pedagogical themes that guide how
Erosion: In earth science, erosion is the action of surface processes that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location where it is deposited. Erosion is distinct from weathering which involves no movement. Removal of rock or soil as clastic sediment is referred to as physical or mechanical erosion; this contrasts with chemical erosion, where soil or rock material is removed from an area by dissolution. Eroded sediment or solutes may be
Valley Forge: Valley Forge functioned as the third of eight winter encampments for the Continental Army's main body, commanded by General George Washington, during the American Revolutionary War. In September 1777, Congress fled Philadelphia to escape the British capture of the city. After failing to retake Philadelphia, Washington led his 12,000-man army into winter quarters at Valley Forge, located approximately 18 miles (29 km) northwest of Philadelphia. They remained there for six months, from December 19, 1777 to
