Moses Coulee in the US showing multiple flood basalt flows of the Columbia River Basalt Group. The upper basalt is Roza Member, while the lower canyon exposes Frenchmen Springs Member basalt A flood basalt (or plateau basalt [ 1 ] ) is the result of a giant volcanic eruption or series of eruptions that covers large stretches of land or the ...
A view through a coulee in Alberta, with steep but lower sides, and water in the bottom. Coulee, or coulée (/ ˈ k uː l eɪ / or / ˈ k uː l iː /), [1] is any of various different landforms, all of which are kinds of valleys or drainage zones. The word coulee comes from the Canadian French coulée, from French couler 'to flow'.
Greenhouse gasses act as the internal forcing of the climate system. Particular interests in climate science and paleoclimatology focus on the study of Earth climate sensitivity, in response to the sum of forcings. Analyzing the sum of these forcings contributes to the ability of scientists to make broad conclusive estimates on the Earth’s ...
Moses Coulee is the second-largest and westernmost canyon of the Channeled Scablands, located about 30 kilometres (19 mi) to the west of the larger Grand Coulee. This water channel is now dry, but during glacial periods, large outburst floods with discharges greater than 600,000 m 3 /s (21,000,000 cu ft/s) carved the channel. [ 1 ]
The larger cataract was that of the upper Grand Coulee, where the river roared over an 240 m (800 ft) waterfall. The eroding power of the water plucked pieces of basalt from the precipice, causing the falls to retreat 32 km (20 mi) and self-destruct by cutting through to the Columbia River valley near what is now the Grand Coulee Dam.

The Coulee Region is the southwestern part of the Driftless Area in Wisconsin. It is named for its numerous ravines. It is named for its numerous ravines. Never covered by ice during the last ice age , the area lacks the characteristic glacial deposits known as drift .
Tectonic–climatic interaction is the interrelationship between tectonic processes and the climate system. The tectonic processes in question include orogenesis, volcanism, and erosion, while relevant climatic processes include atmospheric circulation, orographic lift, monsoon circulation and the rain shadow effect.
Grand Coulee is a large coulee on the Columbia River Plateau.This area has underlying granite bedrock, formed deep in the Earth's crust 40 to 60 million years ago. The land periodically uplifted and subsided over millions of years giving rise to some small mountains and, eventually, an inland sea.
