An arête is a thin, knife-like ridge of rock formed by the erosion of parallel glacial valleys or converging cirques. Clouds Rest and Striding Edge are examples of famous arêtes, with Clouds Rest located in Yosemite National Park, California and Striding Edge in the Lake District of England. Arêtes are commonly formed when two glaciers erode parallel U-shaped valleys, leaving a central ridge between them that is sharpened by freeze-thaw weathering.

Arêtes
An arête is a sharp, narrow ridge formed by the erosion of adjoining corries (cirques) by glaciers. As glaciers expand due to increased snow and ice, they erode and carve the underlying landscape. This can result in the formation of U-shaped valleys, corries, tarns, and arêtes. Crib Goch in Wales is a prominent example of an arête, formed from the erosion of two opposing corries that were once occupied by alpine glaciers. It is a steep and narrow ridge that can be dangerous to climb, especially in winter conditions. Arêtes are common landforms found in mountainous areas that have been subjected to past glaciation.
Glacial landforms2
This document describes various landforms created by glacial erosion and deposition. It defines cirques, corries, and cwms as hollows on mountainsides deepened and widened by corrie glaciers. Arêtes are knife-edged ridges between corries, while pyramidal peaks form when multiple corries erode a central horn-shaped area. Glacial troughs or U-shaped valleys have hanging valleys, truncated spurs, and misfit streams. Features of glacial deposition include till, moraines, drumlins, eskers, kames, kettles, and outwash plains.

The document discusses the geology around Lake Tahoe, including the area's granite formations from the underlying Sierra Nevada batholith. It also describes various rock types found in the region such as diorite, andesite, gneiss, and an angular unconformity example on Twin Peaks. Local plants and animals like the sagebrush lizard and mule's ear flower are also mentioned. The area was impacted by a large 2007 wildfire on Angora Ridge that destroyed homes but led to new construction.
Glacial features
The document discusses different types of glacial ice formations including glaciers, ice caps, ice sheets, and niche ice. It provides examples of each type through photographs of glaciers in locations like Wyoming, Ecuador, Alaska, and New Zealand. The text also examines glacial landforms created by erosion and deposition as glaciers advance and retreat, such as moraines, eskers, drumlins, and outwash plains.
Ezekel gulls
The gulls of Sulphur Bay make their nests each spring on the rocks around the edge of the lake. They do not build nests in trees like other birds. Sulphur Bay provides a warm area for the gulls to live, but it can also cause some problems for them. The bay is an important habitat for observing the birds from a nearby walkway, though permission is required to access the rocks at Sulphur Point. The water at Sulphur Bay stays warm due to heat from underground magma reaching the earth's surface in some places like Rotorua, causing the water to boil.

Blizzards bring heavy snow and wind making travel difficult and dangerous. Tornadoes form from hot air that starts spinning rapidly. It is best to take shelter during severe weather.
Ppt s2u8 different landscapes
This document describes different types of landscapes:
- Mountainous landscapes contain mountains, peaks, slopes, mountain ranges, valleys, and rivers.
- Plains and flat lands lack high mountains and contain flat land, fields, straight roads, valleys, and rivers.
- Coastal landscapes have cliffs, beaches, islands, archipelagos, and harbors.
- Rainforests are hot and rainy year-round, containing many trees, plants, and animal species like amphibians, birds, reptiles, mammals, and insects.
- The poles are very cold with ice, snow, penguins, seals, polar bears, whales, and Inuit people living in igloos.
#6.1 Subduction
Subduction zones occur when denser oceanic crust slides beneath less dense continental crust, forming volcanic mountain ranges along coastlines like the Andes and Cascades, or when oceanic crust subducts beneath other oceanic crust, forming island arc volcanoes such as the Aleutians and Japan. The Ring of Fire surrounds the Pacific Ocean and experiences many volcanoes due to its numerous subduction zones.
Rocks
Rocks are divided into three main groups based on how they are formed: igneous, sedimentary, and metamorphic. Igneous rocks form from cooled magma, sedimentary rocks form from compressed plant and rock remains, and metamorphic rocks form from rocks subjected to heat or pressure. Granite forms from slowly cooled magma and basalt forms from quickly cooled magma. Sandstone forms from compressed sand layers and limestone forms from compressed sea creature remains. Quartzite forms from metamorphosed sandstone and marble forms from metamorphosed limestone. Rocks are extracted through drilling, shaft mining, or quarrying.

Polar bears are endangered due to melting sea ice in the Arctic Circle caused by global warming, reducing their habitat and ability to hunt seals. If polar bears go extinct, it could disrupt the entire Arctic food chain. There are currently estimated to be only 22,000 polar bears remaining.
Deserts of Australia
The Great Sandy Desert is Australia's second largest desert located in northwest Western Australia covering 284,993 square kilometers. The Simpson Desert is the fourth largest desert in Australia and the largest sand dune desert globally, spanning parts of Queensland, South Australia, and the Northern Territory where they meet at Poeppel Corner. The Great Victoria Desert is Australia's largest desert and the third largest in the world, covering 348,750 square kilometers across Western Australia and South Australia.
Glacial Features On Topographic Maps
Glacial landforms are features formed by the action of glaciers such as U-shaped valleys, cirques, arêtes, and horns. U-shaped valleys form when glaciers erode a river valley into a broader U-shape. Cirques are bowl-shaped depressions carved by alpine glaciers. Arêtes are sharp ridges formed between adjacent cirque glaciers. Horns are high mountain peaks formed where cirque walls intersect. Moraines are ridges of glacial debris and include terminal, lateral, and recessional moraines.

Glacial legacies new
Glaciers covered most of the northeastern United States during the last ice age, leaving behind distinctive geological features. During this time, continental glaciers as thick as a mile advanced as far south as New York. As the glaciers retreated around 10,000 years ago, they sculpted U-shaped valleys, deposited unsorted sediments and erratic boulders, and formed landforms like drumlins, eskers, and moraines that shape the region's landscape today. Evidence of glacial erosion such as striations, polish, and chatter marks can still be seen on exposed bedrock throughout the Northeast.

Geology of Yosemite Lakes Park, Ca
The Sierra Nevada uplifts at a rate of 4 centimeters per 100 years due to the subduction of the Farallon Plate under the North American Plate. The Sierran Block forms the core of the Sierra Nevada and consists of granite, granodiorite, and diorite plutonic rocks. Yosemite Lakes Park's geology is dominated by the exfoliating granite dome of Revis Mountain, which stands at 2,162 feet and displays igneous intrusions. The region's hydrology is shaped by its Mediterranean climate, and Coarsegold Creek is a source of placer gold deposits.

The park's hydrology is shaped by its Mediterranean climate, with wet winters bringing significant rainfall that is an important source of water for California.
Anne Claire Science Powerepoint Final!
Glaciers erode and shape the landscape by picking up rocks, dirt, and other debris as they move. Most of the world's largest glaciers are located in Alaska, where the Hubbard Glacier is the largest tidewater glacier in North America. Glaciers help provide fresh water for drinking and irrigation, but storing over 70% of the Earth's fresh water, melting glaciers threaten to raise sea levels by up to 80 meters if climate change is not addressed.
Plate Tectonics
This document describes the four main types of plate tectonic boundaries: divergent, convergent, transform, and subduction. At divergent boundaries, plates move apart from each other, creating mid-ocean ridges and rift valleys on land. At convergent boundaries, plates move toward each other, resulting in mountain building or one plate subducting under the other. Transform boundaries involve plates sliding horizontally past one another, forming strike-slip faults. Subduction occurs when one oceanic plate sinks beneath another plate into the mantle.
Glacial landforms
The document contains photos and descriptions of various glacial landforms and features. It includes images and explanations of niche glaciers in Wyoming, an ice cap on Cotopaxi volcano in Ecuador, glaciers in Alaska and West Greenland, retreating glaciers in New Zealand and Canada, glacial erosion features like striations and erratics, lateral and terminal moraines on Bylot Island, and diagrams labeling landforms created by glacial erosion and deposition including U-shaped valleys, hanging valleys, and drumlins.
Glacial transportation and deposition
This document discusses different types of glacial landforms formed by the deposition of debris (moraine) transported and deposited by glaciers. It describes erratics as large rocks transported far from their source, moraines as ridges of glacial debris including terminal, lateral, and recessional moraines, and drumlins as streamlined hills that indicate the direction of past ice flow. Drumlins are proposed to form through subglacial deformation as the glacier becomes overloaded with debris and moulds it into characteristic elongated shapes aligned with ice movement.
Glacial legacies new
At least 4 ice ages occurred where glaciers covered most of New York and Vermont. This included the last continental glacier called the Wisconsin Ice Sheet which covered the area around 20,000 years ago. Evidence of glaciers can still be seen today through features like drumlins, eskers, striations on bedrock, and U-shaped valleys carved out by the ice.
Ahmad glacier
Glaciers form from compacted snow and ice in areas where snowfall exceeds melting. They are large masses of ice that flow due to basal slip and plastic deformation. There are two main types of glaciers - ice sheets that form over large land areas, and valley glaciers that form in mountainous regions. Glaciers erode land and leave behind features like U-shaped valleys, cirques, and moraines as they advance and retreat over time.
Adirondack mountainseditreferences
The Adirondack Mountains in New York form a circular dome consisting of many summits rather than a connected mountain range. There are 46 high peaks over 4,000 feet considered part of "The 46". Mount Marcy is the highest at 5,344 feet. The mountains were formed during the Grenville Orogeny approximately 1 billion years ago and consist of metamorphic rocks like gneiss and marble. Glaciers helped shape the landscape, depositing erratic boulders.
Glen Alpine to Grass Lake
This 5.45 mile hike begins at Glen Alpine Trailhead and follows an old road to Glen Alpine Springs Resort before reaching Grass Lake. The hike goes around the southern shore of the lake with views of the mountains and a cascade on the west side of the lake. Desolation Wilderness was formed through glaciation that carved out basins holding nearly 130 lakes. Along the way, hikers can see granite rock formations, sandstone, California corn lilies, and Sierra garter snakes.
Hills And Mountains
There are key differences between hills and mountains. Hills have gentle slopes that can be easily climbed, while mountains have steep slopes and may have glaciers and snowfields. Mountains are formed by tectonic plate movement which can cause mountain ranges like the Himalayas. Glaciers form from accumulated snow in mountain valleys and carve out U-shaped valleys as they flow downhill.

Was the Olympics Worth it for the Environment?
The 2012 London Olympics made significant efforts towards sustainability and environmental protection. The stadium used recycled steel for its structure and roof. Carbon emissions were cut by 47% through renewable energy and green suppliers. Nearly all waste was diverted from landfill and over 70% was recycled. The legacy of the games included extensive regeneration of the surrounding area through tree planting, soil remediation, and underground power lines to enhance the environment.
Olympics 2012
The document discusses several negative social impacts of hosting the 2012 Olympics in London, including noise pollution from increased traffic and events, overcrowding on public transportation as seen in tube stations, increased security through more police and private security personnel as well as surveillance technologies, local businesses being displaced, the high price of tickets limiting access, and strict visa requirements preventing some families from attending. In conclusion, while there may be positive impacts as well, the document argues that overall the Olympics were not worth hosting due to these social disadvantages.
Ice on the land
1) Glaciers retreat due to less snowfall in the accumulation zone and rising temperatures in the ablation zone caused by global warming.
2) The glacier has accumulated in the u-shaped valley it resides in, carrying debris like moraines.
3) Glacial troughs form as the mass of ice abrades and erodes the valley walls and floor over time, creating a characteristic u-shape.

It shows step-by-step instructions with illustrations on how to take the tie and wrap it around your neck, pass one side through a loop, and tighten it into place. The entire process is demonstrated slowly and clearly so anyone can learn to properly tie a tie.
Hanging Valleys
The document discusses the formation of hanging valleys over several centuries or millennia as glaciers erode the main valley deeper than tributary valleys, leaving them 'hanging' high above the main valley floor. It provides the example of Cym Bochlwyd, a classic hanging valley in North Wales, and explains that glacial overdeepening is responsible for eroding valleys hundreds of meters underground, leaving hanging valleys as evidence of glacial erosion over time.
Corries
The document describes the formation of cirques and corrie lakes through glacial erosion processes. At high altitudes, snow accumulates in hollows and is compressed into firn and eventually ice by additional snowfall. The weight of the ice causes it to erode the surrounding bedrock through plucking and abrasion, widening the hollow over time into a characteristic armchair shape. Weathering further down also contributes to erosion. As the glacier melts, a corrie lake sometimes remains behind, contained by the rock lip formed from deposited debris.
Sidewinder Rattle Snake
The sidewinder rattlesnake lives in the Mojave and Sonoran deserts of Southwestern America. It has adapted to the hot, dry climate through behaviors like moving in an S-shape across the sand to avoid overheating its body, and hiding under the top layer of sand during the day to stay cool. As a nocturnal hunter, it uses pits on its face to detect the infrared radiation of warm-blooded prey like rodents through the sand.

A.为什么留学生需要操作留信认证?
留信认证全称全国留学生信息服务网认证,隶属于北京中科院。①留信认证门槛条件更低,费用更美丽,并且包过,完单周期短,效率高②留信认证虽然不能去国企,但是一般的公司都没有问题,因为国内很多公司连基本的留学生学历认证都不了解。这对于留学生来说,这就比自己光拿一个证书更有说服力,因为留学学历可以在留信网站上进行查询!
B.为什么我们提供的毕业证成绩单具有使用价值？
查询留服认证是国内鉴别留学生海外学历的唯一途径但认证只是个体行为不是所有留学生都操作所以没有办理认证的留学生的学历在国内也是查询不到的他们也仅仅只有一张文凭。所以这时候我们提供的和学校颁发的一模一样的毕业证成绩单就有了使用价值。乌龟和王八贼头贼脑的倒也逗人喜爱日上三竿时山娃总爱窜进自家瓜棚里跟小伙伴们坐着聊天聊着聊着便忍不住往瓜田里逡巡一番抱起一只硕大的西瓜用石刀劈开抑或用拳头砸开每人抱起一大块就啃啃得满嘴满脸猴屁股般的红艳大家一个劲地指着对方吃吃地笑瓜裂得古怪奇形怪状却丝毫不影响瓜味甜丝丝的满嘴生津遍地都是瓜横七竖八的活像掷满了一地的大石块摘走二三只爷爷是断然发现不了的即便发现爷爷也不恼反而教山娃辨认孰熟孰嫩孰甜孰淡水

Arêtes
- 2. What is an Arête? An arête is a thin, knife-like, ridge of rock.
- 3. How are arêtes formed? They are usually formed when two glaciers erode parallel U-shaped valleys. The arête is the ridge separating the two valleys. They can also be formed when two corries (cirques) erode towards each other. The edge is then sharpened by freeze-thaw weathering, and the slopes on either side are steepened by plucking.
- 4. Arêtes Around the World Clouds Rest is a mountain in Yosemite Village in California, USA. Striding Edge is part of the Helvellyn mountain in the Lake District in England.
- 5. Arêtes Around the World (cont).. The Sawtooth is joins onto the Mount Bierstadt in Colorado, USA. The Garden Wall is in the Glacier National Park in Montana, USA.
