Geography Of Long Island
Long Island is in southeastern New York, United States, separated from the rest of the state by the East River and from Connecticut by Long Island Sound. Long Island contains four counties, of which the western two are boroughs (Queens and Brooklyn) of New York City, and the other two ( Nassau and Suffolk) are mainly suburban. Geology Long Island, as part of the Outer Lands region, is formed largely of four spines of glacial moraine, with a large, sandy outwash plain towards its barrier islands and the Atlantic Ocean. These moraines consist of gravel and loose rock left behind during the two most recent pulses of Wisconsin glaciation some 21,000 years ago (19,000 BC). The northern moraine, which directly abuts the North Shore of Long Island at points, is known as the Harbor Hill moraine. The more southerly moraine, known as the Ronkonkoma moraine, forms the "backbone" of Long Island; it runs primarily through the very center of Long Island, roughly coinciding with the le ...

Long Island
Long Island is a densely populated island in the southeastern region of the U.S. state of New York, part of the New York metropolitan area. With over 8 million people, Long Island is the most populous island in the United States and the 18th-most populous in the world. The island begins at New York Harbor approximately east of Manhattan Island and extends eastward about into the Atlantic Ocean and 23 miles wide at its most distant points. The island comprises four counties: Kings and Queens counties (the New York City boroughs of Brooklyn and Queens, respectively) and Nassau County share the western third of the island, while Suffolk County occupies the eastern two thirds of the island. More than half of New York City's residents (58.4%) lived on Long Island as of 2020, in Brooklyn and in Queens. Culturally, many people in the New York metropolitan area colloquially use the term "Long Island" (or "the Island") to refer exclusively to Nassau and Suffolk counties, a ...

Atlantic Ocean
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the " Old World" of Africa, Europe and Asia from the " New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N.

Jayne's Hill
Jayne's Hill (also known as High Hill, West Hills, Oakley's Hill, and Janes Hill) is the highest point on Long Island, New York, with an elevation of between and above sea level. It is situated on the Harbor Hill moraine, a terminal moraine that makes up the northern spine of Long Island, in West Hills County Park in Suffolk County, a little more than a mile to the north of Melville. Name and height The United States Board on Geographic Names based on a 1903 ruling calls it "High Hill." On the Geographic Names Information System it is listed as 387 feet based on the National Elevation Dataset. Suffolk County, which owns the peak, calls it Jayne's Hill and lists its elevation on its website as 400 feet. An interpretative sign in the park refers to it as "Jaynes Hill" (no apostrophe) and lists the height as 401 feet. History Jayne's Hill has been known by several different names. In 1825 Long Island historian Silas Wood called it "Oakley's High Hill Field" with a surveyo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kettle Lake
A kettle (also known as a kettle lake, kettle hole, or pothole) is a depression/hole in an outwash plain formed by retreating glaciers or draining floodwaters. The kettles are formed as a result of blocks of dead ice left behind by retreating glaciers, which become surrounded by sediment deposited by meltwater streams as there is increased friction. The ice becomes buried in the sediment and when the ice melts, a depression is left called a kettle hole, creating a dimpled appearance on the outwash plain. Lakes often fill these kettles; these are called kettle hole lakes. Another source is the sudden drainage of an ice-dammed lake. When the block melts, the hole it leaves behind is a kettle. As the ice melts, ramparts can form around the edge of the kettle hole. The lakes that fill these holes are seldom more than deep and eventually fill with sediment. In acid conditions, a kettle bog may form but in alkaline conditions, it will be kettle peatland. Overview Kettles are fluvi ...

Ronkonkoma Lake
Lake Ronkonkoma is a freshwater lake in Suffolk County, New York. It is a kettle lake formed by retreating glaciers and is the largest freshwater lake on Long Island; it has a circumference of about and is across on average. The lake is owned by the Town of Islip under the terms of the Nichols Patent. The land around it is controlled by three town governments – Smithtown, Islip and Brookhaven. The separation originated because three different Native American communities claimed lands on different shores, and these claims continued when the tribes gave separate deeds to the land under their control. The name Ronkonkoma comes from an Algonquian expression meaning "boundary fishing-lake", also earlier written as Raconkumake and Raconkamuck. Beginnings Smithtown founder Richard Smith's original holdings included the headwaters of the Nissequogue River east to a "freshwater pond called Raconkamuck," which translates as "the boundary fishing place" in the Algonquian languag ...

Glaciers
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its ablation over many years, often centuries. It acquires distinguishing features, such as crevasses and seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand. Between latitudes 35°N and 35°S, glaciers occur onl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Appalachian Mountains
The Appalachian Mountains, often called the Appalachians, (french: Appalaches), are a system of mountains in eastern to northeastern 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. Definitions vary on the precise boundaries of the Appalachians. The United States Geological Survey (USGS) defines the ''Appalachian Highlands'' physiographic division as consisting of 13 provinces: the Atlantic Coast Uplands, Eastern Newfoundland Atlantic, Maritime Acadian Highlands, Maritime Plain, Notre Dame and Mégantic Mountains, Western Newfoundland Mountains, Piedmont, Blue Ridge, Valley and Ridge, St. Lawrence Valle ...

Hempstead Plains
The Hempstead Plains is a region of central Long Island, in what is now Nassau County, in New York State. It was once an open expanse of native grassland estimated to once extend to about . It was separated from the North Shore of Long Island by the Harbor Hill Moraine, later approximately Route 25. The modern Hempstead Turnpike approximately traces the separation of the plain from the South Shore of Long Island. The east-west extent was from somewhat west of the modern Queens, New York City border to slightly beyond the Suffolk County border. The Town of Hempstead, now America's most populous civil township, was first settled by Europeans around 1644. Although the settlers were from the English colony of Connecticut, a patent was issued by Dutch New Netherland after the settlers had purchased land from the local Native Americans. The town may have been named for either Hemel Hempstead in England, or the city of Heemstede in North Holland. In early US history, the Hempstead ...

Outwash Plain
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 meltwater at the snout of the glacier deposits its load of sediment over the outwash plain, with larger boulders being deposited near the terminal moraine, and smaller particles travelling further before being deposited. Sandurs are common in Iceland where geothermal activity accelerates the melting of ice flows and the deposition of sediment by meltwater. Formation Sandurs are found in glaciated areas, such as Svalbard, Kerguelen Islands, and Iceland. Glaciers and icecaps contain large amounts of silt and sediment, picked up as they erode the underlying rocks when they move slowly downhill, and at the snout of the glacier, meltwater can carry this sediment away from the glacier and deposit it on a broad pla ...

South Shore (Long Island)
The South Shore of Long Island, in the U.S. state of New York, is the area along Long Island's Atlantic Ocean shoreline. Description Though some consider the South Shore to include parts of Queens, particularly the beach communities in the Rockaways such as Belle Harbor, the term is generally used to refer to the Long Island coastline in Nassau and Suffolk counties. It is often used as a generic name for the entire southern half of Long Island rather than just the area immediately adjacent to the coastline. The South Shore tends to be diverse in culture and income as it varies from one hamlet or village to another. In Suffolk County, there still remain pockets of old money from the Gilded Age, including the country seats of families from the Vanderbilts, Havemeyers, and Bournes to the Gardiners, Bayard-Cutting as well as many others. The South Shore is also home to the seaside resort of The Hamptons on its east end, located on the South Fork of Long Island. On its wes ...
