paragraph_text: Most of the state has a humid subtropical climate, with the exception of some of the higher elevations in the Appalachians, which are classified as having a mountain temperate climate or a humid continental climate due to cooler temperatures. The Gulf of Mexico is the dominant factor in the climate of Tennessee, with winds from the south being responsible for most of the state's annual precipitation. Generally, the state has hot summers and mild to cool winters with generous precipitation throughout the year, with highest average monthly precipitation generally in the winter and spring months, between December and April. The driest months, on average, are August to October. On average the state receives 50 inches (130 cm) of precipitation annually. Snowfall ranges from 5 inches (13 cm) in West Tennessee to over 16 inches (41 cm) in the higher mountains in East Tennessee.

paragraph_text: The Rousseau Range is a small mountain range in southeastern Alaska, United States, located just north of the Peabody Mountains. It has an area of 264 km and is a subrange of the Boundary Ranges which in turn form part of the Coast Mountains. The range is located entirely within Misty Fjords National Monument.

paragraph_text: Pieck Range () is a short mountain range surmounted by Zwiesel Mountain, located at the east side of Humboldt Graben in the Petermann Ranges, Wohlthat Mountains in Antarctica.

paragraph_text: East of the divide, several roughly parallel ranges cover the southern part of the state, including the Gravelly Range, the Madison Range, Gallatin Range, Absaroka Mountains and the Beartooth Mountains. The Beartooth Plateau is the largest continuous land mass over 10,000 feet (3,000 m) high in the continental United States. It contains the highest point in the state, Granite Peak, 12,799 feet (3,901 m) high. North of these ranges are the Big Belt Mountains, Bridger Mountains, Tobacco Roots, and several island ranges, including the Crazy Mountains and Little Belt Mountains.

paragraph_text: The Sifton Ranges are a mountain range along the west side of the Rocky Mountain Trench in northern British Columbia, Canada. It has an area of 1823 km and is a subrange of the Cassiar Mountains which in turn form part of the Interior Mountains.

paragraph_text: The Muskwa Ranges are a group of mountain ranges in northern British Columbia, Canada. They are part of the Northern Rockies section of the Rocky Mountains and are bounded on their west by the Rocky Mountain Trench and on their east by the Rocky Mountain Foothills. They are delimited on the north by the Liard River and on the south by the Peace Reach of the Lake Williston reservoir (formerly the Peace River), south of which the next major grouping of the Rockies is the Hart Ranges.

paragraph_text: The Sawtooth Range is a mountain range of the Rocky Mountains in central Idaho, United States, reaching a maximum elevation of at the summit of Thompson Peak. It encompass an area of spanning parts of Custer, Boise, Blaine, and Elmore counties, and is bordered to the east by the Sawtooth Valley. Much of the mountain range is within the Sawtooth Wilderness, part of the Sawtooth National Recreation Area and Sawtooth National Forest.

paragraph_text: The Round Mountain, one of three peaks of the same name in the region, is a mountain located on the Main Range of the Snowy Mountains, part of the Great Dividing Range, in southeastern New South Wales, Australia.

paragraph_text: The topography of the state is roughly defined by the Continental Divide, which splits much of the state into distinct eastern and western regions. Most of Montana's 100 or more named mountain ranges are concentrated in the western half of the state, most of which is geologically and geographically part of the Northern Rocky Mountains. The Absaroka and Beartooth ranges in the south-central part of the state are technically part of the Central Rocky Mountains. The Rocky Mountain Front is a significant feature in the north-central portion of the state, and there are a number of isolated island ranges that interrupt the prairie landscape common in the central and eastern parts of the state. About 60 percent of the state is prairie, part of the northern Great Plains.

paragraph_text: The Appalachian Mountains (French: les Appalaches), often called the Appalachians, are a system of mountains in eastern North America. The Appalachians first formed roughly 480 million years ago during the Ordovician Period. They once reached elevations similar to those of the Alps and the Rocky Mountains before experiencing natural erosion. The Appalachian chain is a barrier to east - west travel, as it forms a series of alternating ridgelines and valleys oriented in opposition to most highways and railroads running east - west.

paragraph_text: The Great Plains lie west of the Mississippi River and east of the Rocky Mountains. A large portion of the country's agricultural products are grown in the Great Plains. Before their general conversion to farmland, the Great Plains were noted for their extensive grasslands, from tallgrass prairie in the eastern plains to shortgrass steppe in the western High Plains. Elevation rises gradually from less than a few hundred feet near the Mississippi River to more than a mile high in the High Plains. The generally low relief of the plains is broken in several places, most notably in the Ozark and Ouachita Mountains, which form the U.S. Interior Highlands, the only major mountainous region between the Rocky Mountains and the Appalachian Mountains.

paragraph_text: Mount Twynam is a mountain located on the Main Range, part of the Great Dividing Range, in the Snowy Mountains in New South Wales, Australia. The mountain is located close the border between New South Wales and Victoria.

paragraph_text: The X-10 Graphite Reactor at Oak Ridge National Laboratory (ORNL) in Oak Ridge, Tennessee, formerly known as the Clinton Pile and X-10 Pile, was the world's second artificial nuclear reactor (after Enrico Fermi's Chicago Pile) and was the first reactor designed and built for continuous operation. Argonne National Laboratory's Experimental Breeder Reactor I, located at the Atomic Energy Commission's National Reactor Testing Station near Arco, Idaho, became the first nuclear reactor to create electricity on 20 December 1951. Initially, four 150-watt light bulbs were lit by the reactor, but improvements eventually enabled it to power the whole facility (later, the town of Arco became the first in the world to have all its electricity come from nuclear power generated by BORAX-III, another reactor designed and operated by Argonne National Laboratory). The world's first commercial scale nuclear power station, Obninsk in the Soviet Union, began generation with its reactor AM-1 on 27 June 1954. Other early nuclear power plants were Calder Hall in England, which began generation on 17 October 1956, and the Shippingport Atomic Power Station in Pennsylvania, which began on 26 May 1958. Nuclear power was used for the first time for propulsion by a submarine, the USS Nautilus, in 1954.

The mountain is part of the Carter-Moriah Range of the White Mountains, which runs along the northern east side of Pinkham Notch. The summit is approximately southeast of the center of the town of Gorham. Mount Moriah is flanked to the northeast by Middle Moriah Mountain and to the southwest by Imp Mountain. The summit is located on the Appalachian Trail and affords views in all directions.

paragraph_text: The Rocky Mountain elk ("Cervus canadensis nelsoni") is a subspecies of elk found in the Rocky Mountains and adjacent ranges of Western North America. The winter ranges are most common in open forests and floodplain marshes in the lower elevations. In the summer it migrates to the subalpine forests and alpine basins. Elk have a diverse habitat range that they can reside in but are most often found in forest and forest edge habitat and in mountain regions they often stay in higher elevations during warmer months and migrate down lower in the winter. They may even come down the mountain and leave the forest into some grassland for part of the day but head back into the timber in the evening. The total wild population is about one million individuals.

paragraph_text: The McGregor Range is a mountain range in the Central Interior of British Columbia, located between the main spine of the Rocky Mountains and the Fraser River on the northeast and southwest, and between the Torpy River on its southeast and the McGregor River on its northwest. Though adjacent to the Rockies and very mountainous, the McGregor Range is part of the McGregor Plateau, a subdivision of the Fraser Plateau.

paragraph_text: The Geologic history of the Chiricahua Mountains concerns the Chiricahua Mountains, an inactive volcanic range located in Coronado National Forest of southeastern Arizona, in the United States. They are part of an "archipelago" of mountain ranges known as the sky islands that connect the Sierra Madre Occidental in Mexico with the Rocky Mountains. The Chiricahua Mountains are home to a number of unusual geologic features associated with the Turkey Creek Caldera, some of which are protected by Chiricahua National Monument. The landscape has been dominantly shaped by faulting due to Basin and Range extension during the Miocene, volcanic activity, and erosion.

paragraph_text: The Lincoln Mountains is a mountain range in southeastern Alaska, United States, located on the Alaskan side of the Portland Canal between the Salmon River and the Soule River, near the community of Hyder. It has an area of 235 km and is a subrange of the Boundary Ranges which in turn form part of the Coast Mountains.
