Why are cobbles and boulders composed of Precambrian gneiss commonly found on top of the surface bedrock in the Catskills?
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.
Why is the moon's surface heavily pitted and the earth is not?
The moon doesn't have an atmosphere and there any space matter will strike directly, where the earths atmosphere generally burns up space matter on entry. However, if you were on the moon and looked at the earth we are heavily pitted, think of the landscape near where you are
What do we call the water that does not sink but flows on the ground?
We call the water that does not sink but flows on the ground "surface water." This can include rainwater, rivers, streams, and lakes that remain on the Earth's surface rather than infiltrating into the ground.
Which physical characteristic of the bedrock are responsible for the oldest rock remaing at the highest elevation?
The oldest rock remaining at the highest elevation is typically due to the resistant nature of the bedrock. Rocks that are harder and more resistant to erosion will remain at higher elevations over geologic time scales, while softer rocks erode more easily. This can create features like mountain ranges where harder rocks have been uplifted and exposed at high elevations.
How wind erosion might affect rock?
Wind erosion acts by blasting sediment at other rocks, or by using its own sheer force to buffet the rock. Wind erosion would cause the rock to recede, while some more resistant parts would remain prominent.
What mineral least susceptible to chemical attack on earths surface?
Quartz is the mineral least susceptible to chemical attack on Earth's surface. Its strong silicon-oxygen bonds make it highly resistant to weathering and chemical alteration. This durability allows quartz to remain prevalent in various environments, often forming the basis of sand and sedimentary rocks. As a result, it is commonly found in numerous geological settings.
Did anything happen to the surface of the pyrex test tube in this flame?
Pyrex is resistant to thermal shock and can withstand high temperatures, so the surface of the Pyrex test tube likely did not change in the flame. It should remain unaffected under normal laboratory conditions.
Will this landscape with rocks remain this way forever?
no, because the next person will change it when they live near there
What are the odds of a terrorist attack on the US?
It remain an ever present and real threat.
Why does pure silver remain shiny?
The surface was not altered by hydrogen sulfide.
Can a tornado go underground?
Tornadoes cannot go underground. They form from rotating thunderstorms and remain above the ground surface as they move across the landscape. However, they can cause damage to structures below ground such as basements or underground shelters.
When will the aliens attack?
There is no evidence to suggest that aliens are planning to attack Earth. It is important to base beliefs on facts and remain open to new information.
What does 'you must be on your guard or' mean?
It means you must remain alert, anticipating an attack or other trouble.
How does the surface of the cornea remain moist and free from foreign bodies?
lacrimal glands
How long does marijuana residue remain detectable on a surface such as a car?
An week from now...
How are volume and surface area the same when volume stays the same?
There is no reason for the surface area to remain the same even if the volume is the same.
How will the velocity of the book change as it moves across a surface with no friction?
The velocity of the book will remain constant as it moves across a surface with no friction.
