A swath of bedrock in northern Quebec may be the oldest known piece of the Earth’s crust.
Likewise, which rock layer is the most resistant to weathering? Sandstone is a sedimentary rock that is highly resistant to weathering. Other sedimentary rocks you will encounter are mudstone and siltstone. These are soft and easily weathered (lots in the Painted Desert). Yet another sedimentary rock you will see is limestone.
Correspondingly, how were the striations made?
1) Frost action cracked the bedrock during the ice age. 2) Rocks at the bottom of the glaciers were dragged over the bedrock. 3) Particles carried by winds scratched the bedrock during the ice age.
Are river deposits sorted or unsorted?
So as water moves through these unsorted deposits, it will select out only the smaller bits of sand and silt that it can carry. This produces a sorted deposit of just the sand and smaller particles transported by liquid water. Often these deposits form layer on layer and show the direction that rivers flowed.
What landscape region is New York City?

In which New York landscape region is Niagara Falls located?
The Niagara Region is located on a portion of a great plain which runs east to west from the northern Laurentian Highlands (Canadian Shield) approximately 161 kilometres north of Toronto, Ontario to the southern Allegheny Plateau which form the foothills of the Adirondack Mountains and the Appalachian Mountains.
What is the name of the landscape region that Elmira is in?
The City of Elmira is in the south-central part of the county, surrounded on three sides by the Town of Elmira. It is in the Southern Tier of New York, a short distance north of the Pennsylvania state line.
Is the Manhattan prong a Highland?
Equivalent rocks in western Connecticut are called the Housetonic Highlands. The Manhattan Prong is a smaller belt of ancient rock in southern New York (including Manhattan, the Bronx, and segments of Brooklyn and Staten Island), parts of Westchester County, and upland portions of southwestern Connecticut.
Which New York landscape region includes the location 43 30 N 75 45 W?

What type of landscape is the Manhattan prong?
The Manhattan Prong, also known as the Manhattan Hills, is a landscape of rolling hills and valleys with elevations generally less than 100 meters (330 feet) above sea level, but ranging from sea level to nearly 275 meters (900 feet) above sea level.

( Rivers in one color and. all others in a different color) a. What is the difference between a Plateau and Plain? In which Landscape Region is. a.
Is striation erosion or deposition?
With the weight of the ice over them, these rocks can scratch deeply into the underlying bedrock making long, parallel grooves in the bedrock, called glacial striations.
How are cirques formed?
Corrie or Cirque Formation. Corries or cirques are mountain valley heads which have been shaped into deep hollows by the erosion of small glaciers. Under more intense conditions ice caps and ice sheets form and the corries may feed ice into larger glacial systems.
How are grooves formed?
Glacial grooves and striations are gouged or scratched into bedrock as the glacier moves downstream. Boulders and coarse gravel get trapped under the glacial ice, and abrade the land as the glacier pushes and pulls them along.
What occurs when a rock is crushed into a pile of fragments?
What occurs when a rock is crushed into a pile of fragments? A The total surface area decreases and chemical composition changes. D The total surface area decreases and chemical composition remains the same.
What does striation mean in geography?
Striations means a series of ridges, furrows or linear marks, and is used in several ways: Glacial striation. Striation (geology), a striation as a result of a geological fault. Striation Valley, in Antarctica. In hyperbolic geometry, a striation is a reflection across two parallel mirrors.
Where are glaciers found?
Most of the world’s glacial ice is found in Antarctica and Greenland, but glaciers are found on nearly every continent, even Africa.
