The Bering & Chukchi Seas: Arctic Coastal Plains & Barriers •The volcanic Aleutian Mountains extend some km ( miles) forming the border between the Pacific Ocean and the Bering Sea. •Beyond the Alaska Peninsula and bordering the Bering Sea, extensive coastal plains are found with numerous lakes and meandering streams. Eastern Africa, part of sub-Saharan Africa comprising two traditionally recognized regions: East Africa, made up of Kenya, Tanzania, and Uganda; and the Horn of Africa, made up of Somalia, Djibouti, Eritrea, and Ethiopia. Eastern Africa consists largely of plateaus and has most of the highest.
The geology of Delaware includes parts of two geologic provinces: the Appalachian Piedmont Province and the Atlantic Coastal Plain Province. The Piedmont occurs in the hilly northernmost part of the state and is composed of crystalline metamorphic and igneous rocks. This chart summarizes the age and distribution of the geologic units that are recognized in the state by the Delaware Geological. Interior Plains physiographic region, and is formed of thick, flat-lying Phanerozoic strata. The Peel Plateau is a striking and rather even land surface lying between the eastern front of the Richardson Mountains and the northern front of the Mackenzie Mountains (Fig. 5).
The eastern part of this province, is the Valley and Ridge w here t he once‑horizontal layers are now faulted and tightly folded in a northeast-southwest direction (parallel to the major structural trend of the Appalachians) such as at Lookout Mountain (whose eastern escarpment marks the edge of the Cumberland Plateau), whereas farther. The plains slope gently from interior highlands toward the Atlantic and Gulf coastlines with few elevations higher than m. The coastal plains are underlain by sedimentary rocks of Cretaceous, Tertiary, and Quaternary age. Cretaceous rocks crop out in a .

The Arctic (/ ˈ ɑːr k t ɪ k / or / ˈ ɑːr t ɪ k /) is a polar region located at the northernmost part of Arctic consists of the Arctic Ocean, adjacent seas, and parts of Alaska (United States), Finland, Greenland (), Iceland, Canada, Norway, Russia, and within the Arctic region has seasonally varying snow and ice cover, with predominantly treeless permafrost.

[C J Yorath; H R Balkwill; R W Klassen]. Arctic Coastal Plain Nest Colonies. The Arctic Coastal Plain is a primary nesting site for many migrating birds, including the Black Brant.
From year to year, the location of brant colonies varies. One explanation for these changes is that the springtime flooding determines which nest sites are available when the brant first arrive in the spring. Arctic - Arctic - Terrain: Although the detail of the terrain in many parts of the Arctic is directly attributable to the Pleistocene glaciations, the major physiographic divisions reveal close correlation with geologic structure.
The two largest shield areas, the Canadian and the Baltic, have developed similar landscapes. West of Hudson Bay, in southwestern Baffin Island, and in Karelia the. The Northern Great Plains is a large region of generally low relief sloping eastward from the Rocky Mountains toward the Missouri and Mississippi Rivers.
Its basic bedrock structure is a broad syncline, punctuated by the Black Hills and a few smaller uplifts, and by structural basins such as the Williston, Powder River, and Denver-Julesburg.
Shallow ocean waters covered a significant part of the interior of North America, including the region we recognize as the Great Plains, for most of Paleozoic and Mesozoic time. Typically between 5, feet of layered sediments, predominantly limestones, shales, and sandstones representing a mixture of seafloor, near-shore, and delta.
The book is a comprehensive compilation of all aspects of the geology of Northwest Borneo (Sarawak, Brunei and Sabah) and the contiguous South China and Sulu Seas.
The sedimentary formations are described, their palaeontology tabulated and ages discussed. Stratigraphic charts illustrate their relationships across the whole region. Northern Canada, colloquially the North, is the vast northernmost region of Canada variously defined by geography and politics.
Politically, the term refers to three territories of Canada: Yukon, Northwest Territories, and rly, the Far North (when contrasted to the North) may refer to the Canadian Arctic: the portion of Canada that lies north of the Arctic Circle, east of Alaska.
Northern Europe is a loosely defined geographical region in er definitions may describe Northern Europe as being roughly north of the southern coast of the Baltic Sea, which is about 54°N, or may be based on other geographical factors such as climate and ecology.A broader definition would include the area of Europe north of the Alps (but excluding Eastern Europe).
Appalachian Mountains - Appalachian Mountains - Geology: The Appalachians are among the oldest mountains on Earth, born of powerful upheavals within the terrestrial crust and sculpted by the ceaseless action of water upon the surface.
The two types of rock that characterize the present Appalachian ranges tell much of the story of the mountains’ long existence. North Asia or Northern Asia (Russian: Северная Азия, romanized: Severnaya Aziya), sometimes also referred to as Siberia, is a sub-region of Asia, consisting of the Russian regions east of the Ural Mountains: Ural, Siberia and the Russian Far region is sometimes also known as Asian Russia (as opposed to the smaller European Russia).
In Delaware, the oldest unit of the Atlantic Coastal Plain is the Potomac Formation. Sediment eroded from the Appalachian Mountains was deposited in rivers and swamps in a tropical climate along the margins of the forming ocean during the latter part of Early Cretaceous time, about million years ago.

LA MOREAUX Geologist United States Geological Survey Published in cooperation with United States Department of Interior, Geological Survey,D. The northern Appalachians are made up of two parts: the St. Lawrence Valley, a small region defined by the St. Lawrence River and St. Lawrence rift system, and the New England province, which formed hundreds of millions of years ago and owes much of its present topography to recent glacial ically speaking, the Adirondack Mountains are quite different than the Appalachian.
Sedimentary and volcanic strata are found in rift valleys in the eastern part of the Piedmont Province, relics of the rifting of Pangea about million years ago.
The Atlantic Coastal Plain is covered by sedimentary layers of the modern passive continental margin. The deeper you go into the Earth the higher the temperature and pressure. The Northern Basin and Range ecoregion is a Level III ecoregion designated by the United States Environmental Protection Agency (EPA) in the U.S.
states of Oregon, Idaho, Nevada, Utah, and contains dissected lava plains, rolling hills, alluvial fans, valleys, and scattered mountain ranges in the northern part of the Great gh arid, the ecoregion is higher and cooler.
Most of the interior of Australia, from the mountains along the eastern margin to the plateaus in the far west, is one vast desert plain. The majority of the world’s most extensive plains were formed as a result of the dominance of erosional and depositional processes over tectonic activity— e.g., uplift or subsidence of the Earth’s crust.
The northern boundary of the Raton section is placed somewhat indefinitely at the northern limit of the area injected by igneous dikes. The eastern boundary of the Raton section is at the eastern margin of the lavas of Mesa de Maya and adjoining mesas, where lava-capped outliers of Ogallala Formation are separated from the Ogallala of the High Plains only by the canyon of Carrizo.
Relief. Three of the country’s large physiographic regions extend into or across the state. The Interior Highlands (Ozark Plateaus and Ouachita provinces) cover part of eastern Oklahoma; the Atlantic Plain (Coastal Plain provinces), extending through Texas to the Gulf of Mexico, is in the southeast; and the Interior Plains, including the Central Lowland and Great Plains provinces, cover the.
Region 3: The Coastal Plain In terms of its geology, the Coastal Plain is the least complicated region of the United States. Following the breakup of Pangaea, as the North American plate began drifting away from the Mid-Atlantic Ridge, mountain building along the eastern margin of North America ceased.A long period of erosion continued from the Cretaceous through the Quaternary, as sediment.northern range is the Arctic Mountains province of the Rocky Mountain System, dominated by the Brooks Range whose sum- mit altitudes are 6, feet.
North of this province are the Arctic Foothills, also part of the Rocky Mountain System, and the Arctic Coastal Plain, the northwestern extension of the Interior Plains.Northern California Living on the Edge: Coastal Hazards in Northern California the northern part of the state to the southern portion.
