Abrasion by wind-carried sand is the leading cause of erosion in New York.
How did the Finger Lakes in the state of New York form quizlet?
These lakes are shaped like fingers- they are long and narrow. They were formed by glaciers that moved across New York during the last Ice Age.
Which rock layer appears most resistant to weathering and erosion?
Igneous rocks are usually solid and are more resistant to weathering. Intrusive igneous rocks weather slowly because it is hard for water to penetrate them.
What is the primary force responsible for most of the transportation of rock material on the surface of Earth?
Erosion is a mechanical process, usually driven by water, wind, gravity, or ice, which transports sediment (and soil) from the place of weathering. Liquid water is the main agent of erosion. Gravity and mass wasting processes (see Chapter 10, Mass Wasting) move rocks and sediment to new locations.
How did the arch most likely form?
An earthquake forced bedrock upward into the shape of an arch.
What formed the NY Finger Lakes?
glaciers
Huge sheets of ice carved out the U-shaped valleys that hold New York’s Finger Lakes. When they retreated north about 10,000 years ago, glaciers left deposits of gravel that dammed streams and caused the depressions to become lakes.
What are Finger Lakes How do they form?
Finger Lakes Formation
Glaciers crept through the area and carved deep slices into the land, pushing the earth and rocks south. Gradually the ice melted and the glaciers receded, leaving shale valleys of water, which are now the Finger Lakes.
Which type of rock is most associated with erosion?
Sedimentary rocks
Sedimentary rocks are formed on or near the Earth’s surface, in contrast to metamorphic and igneous rocks, which are formed deep within the Earth. The most important geological processes that lead to the creation of sedimentary rocks are erosion, weathering, dissolution, precipitation, and lithification.
What type of rock is more prone to erosion?
Soft rock like chalk will erode more quickly than hard rocks like granite. Vegetation can slow the impact of erosion.
What is the strongest agent of weathering erosion and deposition?
A: The strongest agent of weathering, erosion and deposition is water.
Which agent of erosion is primarily responsible for the formation of the barrier islands along the south shoreline of Long Island New York?
Barrier islands form as waves repeatedly deposit sediment parallel to the shoreline. As wind and waves shift according to weather patterns and local geographic features, these islands constantly move, erode, and grow.
What are the major types of weathering processes operating in natural environment on rocks and minerals?
Weathering is the breakdown of rocks at the Earth’s surface, by the action of rainwater, extremes of temperature, and biological activity. It does not involve the removal of rock material. There are three types of weathering, physical, chemical and biological.
What is are the agents of erosion and deposition primarily responsible in each formation?
Water, wind, ice, and waves are the main agents of erosion. The most effective erosion agent is water, which most generally erodes in streams as flowing water.
What most likely caused this natural rock arch?
Water is the main cause of the unique shapes we often see in natural arches. It tends to run in grooves and cracks along the rock’s walls. Because the water flows towards the cracks, it makes these areas wear away faster. Water washes away the softer rock material first, which often leaves an interesting shape behind.
Which feature is most likely caused by chemical weathering?
The most common feature that can be caused purely by chemical weathering is Karst Landscape, which can lead to caverns and sinkholes. In this type of topography, ground water flows through the bedrock which has a significant amount of calcite in it – most commonly limestone.
How did the sea arch in this feature form quizlet?
How is an arch formed along a sea coast? –Coastal deposition of rock material by wave action creates a headland, which is then eroded, forming an arch.
What are Finger Lakes known for?
The Finger Lakes region is known for its breathtaking scenery, outdoor activities, wineries and craft breweries. Clocking in at 9,000-square-miles (we’re about the size of New Jersey!), it may feel intimidating to plan a Finger Lakes visit.
How was New York formed geologically?
New York City is primarily composed of sediments that were metamorphosed during the Taconic and Acadian orogenies roughly 500 – 400 million years ago. Garnets can be found in the rocks of the Hartland Formation and Manhattan Schist (view a NYC rock sample ).
What landform are the Finger Lakes?
Finger Lakes, group of narrow, glacial lakes in west-central New York state, U.S. They lie in north-south valleys between the vicinity of Syracuse (east) and Geneseo (west).
What are the natural resources of the Finger Lakes?
The lakes are multiuse resources for drinking water sources, fishing, swimming, and other forms of recreation. The lakes and rivers of the region supply drinking water to more than 2 million people.
Where are the fossils in the Finger Lakes?
The Staghorn Cliffs of Skaneateles Lake are recognized as one of NY’s premiere paleontological sites, and are well known examples of an ancient coral reef from the Devonian Period, ca. 400-350 million years ago.
