When was most of the sandstone bedrock in New York State formed?
According to the website of the New York State Geological Survey (see related link), the majority of sedimentary bedrock in New York State was deposited in a 160 million year period in the early to middle Paleozoic era from approx. 520 to 360 million years ago.
What sediment was most sandstone bedrock composed of?
Most sandstone bedrock is primarily composed of quartz grains, which are derived from the weathering and erosion of pre-existing rocks. In addition to quartz, sandstone may also contain feldspar, mica, and other minerals, depending on its source material. The grains are typically cemented together by minerals such as silica, calcite, or iron oxides, giving sandstone its characteristic durability and porosity.
What metamorphic rocks form sandstone?
The most common metamorphic rock associated with the regional, contact, or depth of burial metamorphosis of sandstone is quartzite.
Why is sandstone an example of sedimentary rock?
Yes. Sandstone is considered as a clastic sedimentary rock because it is formed from small particles of weathered and eroded rocks from various sources.
Which type of rock is most found as an outcrop inthe allegheny plateau in nys?
In the Allegheny Plateau in New York State, sedimentary rocks are the most commonly found as outcrops. These sedimentary rocks formed over millions of years from the accumulation and compaction of sediments in ancient seas, lakes, and rivers. Examples of sedimentary rocks in this region include sandstone, shale, and limestone.

Most of the surface bedrock found in New York state was formed during which era?
Most of the surface bedrock in New York state was formed during the Paleozoic Era, particularly in the Ordovician and Silurian periods. This era was characterized by significant geological activity, including the formation of marine sediments and the development of various rock types. The bedrock primarily consists of limestone, shale, and sandstone, reflecting the region's ancient oceanic environment.
Which two kinds of adjoining bedrock would most likely have a zone of contact metamorphism?
shale and sandstone

What is the geologic age of the surface bedrock of most of the Allegheny Plateau landscape region in New York StateWhat is the geologic age of the surface bedrock of most of the Allegheny Plateau land?
The surface bedrock of most of the Allegheny Plateau landscape region in New York State is primarily from the late Devonian to early Carboniferous periods, roughly 360 to 300 million years ago. This bedrock mainly consists of sedimentary rocks, including sandstone, shale, and limestone, formed from ancient marine environments. The region's geological history reflects significant erosion and tectonic activity that has shaped its current landscape.
What is the geologic age of the surface bedrock of most of the Allegheny Plateau landscape region in new york state?
The surface bedrock of most of the Allegheny Plateau landscape region in New York state is predominantly from the Devonian period, which occurred approximately 419-359 million years ago. This bedrock consists mainly of sedimentary rocks like shale, sandstone, and limestone, which were deposited during this geologic time period.
What type of bedrock most likely exists in an area that has numerous sinkholes?
Limestone bedrock is most likely to exist in an area with numerous sinkholes. Sinkholes are formed when acidic groundwater dissolves the limestone bedrock, creating underground cavities that can cause the land surface to collapse.
What metamorphic rocks form sandstone?
The most common metamorphic rock associated with the regional, contact, or depth of burial metamorphosis of sandstone is quartzite.
What landscape feature is most likely to be formed from a bedrock layer that is resistant to erosion?
A ridge or a cliff would be most likely to form from a bedrock layer that is resistant to erosion. These features are created when surrounding softer rock is worn away, leaving the harder bedrock exposed.
Which erosional feature most likely formed on the surface of the bedrock under the glacial ice?
Striations would most likely form on the surface of the bedrock under the glacial ice. Striations are caused by the movement of large rocks embedded in the base of a glacier scraping across the bedrock, resulting in long, parallel grooves being carved into the bedrock surface.
Which process lead to formations of thick salt found in bedrock of new york?
The processes most likely formed a burial and compaction which the shale bedrock is found near Ithaca, New York.
Why is sandstone an example of sedimentary rock?
Yes. Sandstone is considered as a clastic sedimentary rock because it is formed from small particles of weathered and eroded rocks from various sources.
