Horizontal sedimentary rock layers.
The Adirondack Mountains region of New York has surface bedrock that is similar in age to the erratics found in the area. Both the bedrock and the erratics are primarily composed of ancient Precambrian rocks, dating back over a billion years. This similarity highlights the geological history of the region, shaped by glacial activity during the last Ice Age.
A region of Earth's surface with similar elevation is known as a plateau or a highland. These areas are characterized by relatively flat or gently sloping terrain at higher elevations compared to the surrounding areas.

No, the bedrock at the South Pole is not at or below sea level. The South Pole sits on the Antarctic Plateau, which is a high, flat, and elevated region with an average height of 9,800 feet (3,000 meters) above sea level. The bedrock beneath the ice is also above sea level.
The Hudson River in New York State has large amounts of metamorphic bedrock exposed at the surface, particularly in the Hudson Highlands region. This area features prominent cliffs and rock formations formed from metamorphic rocks such as gneiss and schist.

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.
Plateau- it has a horizontal bedrock structure and is a continuation of the Allegheny plateau. It looks like mountains because of stream and glacial erosion.
The Allegheny Plateau is primarily composed of sedimentary bedrock, including sandstone, shale, and limestone. These rock types were formed from ancient marine environments and are often layered, reflecting the geological history of the region. The plateau's bedrock is also characterized by coal deposits, which were formed from ancient plant materials during the Carboniferous period. This diverse geological composition contributes to the plateau's unique topography and ecosystems.
Cobbles and boulders composed of Precambrian gneiss are commonly found on the top of the surface bedrock in the Catskills because they were deposited there by glacial action during the last Ice Age. Glaciers transported these rocks from their original bedrock source areas and left them scattered across the region as they melted. The resistant nature of gneiss allows these rocks to remain on the surface long after the glaciers have retreated.

Bedrock formations are solid rock layers that underlie the Earth's loose surface material, such as soil or sediment. These formations are composed of different types of rock, such as granite, basalt, or limestone, and they provide the foundation for the Earth's surface features. Studying bedrock formations can provide insights into the geological history and composition of a region.
The Adirondack Mountains, Taconic Mountains, and the Hudson Highlands have the most resistant bedrock.
