Yosemite is a glaciated landscape, and the scenery that resulted from the interaction of the glaciers and the underlying rocks was the basis for its preservation as a national park. With the end of the last glacial advance, the Columbia settled into its present course. It is the process of friction caused by scuffing, scratching, wearing down, marring, and rubbing away of materials. Glacial striations or striae are scratches or gouges cut into bedrock by glacial abrasion. An ice age is a long period of reduction in the temperature of Earth's surface and atmosphere, resulting in the presence or expansion of continental and polar ice sheets and alpine glaciers.Earth's climate alternates between ice ages and greenhouse periods, during which there are no glaciers on the planet.Earth is currently in the Quaternary glaciation.

The loose and dissolved materials move from one location to another. This section of our specification focuses on the major stores of water and carbon at or near the Earths surface and the dynamic cyclical relationships associated with them. It is the process of friction caused by scuffing, scratching, wearing down, marring, and rubbing away of materials. Erosion is the action of surface processes (such as water flow or wind) 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. Archeological records date human presence back to nearly the end of the Ice Age, but the raging torrents erased the land of clear evidence, leaving us to question who, if anyone, may have survived. To geologists, an ice age is defined by the presence of large amounts of land-based ice. Geomorphology (from Ancient Greek: , g, "earth"; , morph, "form"; and , lgos, "study") is the scientific study of the origin and evolution of topographic and bathymetric features created by physical, chemical or biological processes operating at or near Earth's surface.Geomorphologists seek to understand why landscapes look the way they do, to The word is derived from the Old Norse word tjrn ("a small mountain lake without tributaries") meaning pond. The Early Crew. Jackson Lake and Jenny Lake in Grand Teton National Park are In geomorphology, an outburst flooda type of megafloodis a high-magnitude, low-frequency catastrophic flood involving the sudden release of a large quantity of water. An outwash plain, also called a sandur (plural: sandurs), sandr or sandar, is a plain formed of glaciofluvial deposits due to meltwater outwash at the terminus of a glacier.As it flows, the glacier grinds the underlying rock surface and carries the debris along. The work of the glacier then left an overdeepened U-shaped valley that ends abruptly at a valley or trough end.
