How are glacial grooves made?
Glacial grooves are created when rocks embedded in the base of a glacier scrape the underlying bedrock as the glacier moves. The immense pressure and friction exerted by the moving glacier cause the rocks to plow into the bedrock, leaving long, parallel grooves behind. These grooves are a common feature in areas that were once covered by glaciers during the last ice age.
Which process led to the formation of thick salt deposits found in the bedrock at same locations in NYS?
The thick salt deposits found in the bedrock at some locations in New York State were formed by the evaporation of ancient seas that once covered the region. Over time, as the seawater evaporated, it left behind layers of salt that eventually solidified into the thick deposits we see today.
A geologist finds a section of rock that shows ripple marks What does the presence of ripple marks say about the area where the rock formed?
The presence of ripple marks indicates that the area where the rock formed used to be covered by moving water, such as a river, stream, or a wave-dominated shoreline. Ripple marks provide evidence of past water currents and can help geologists interpret the depositional environment of the rock.
Which is evidence that an area was once covered by a glacier?
Evidence a region was (or just as importantly, was not) covered by glaciers usually comes in the form of such glacial features asmorainescirques"erratics" (rocks moved from one place to another)glacial tarnsmost especially wide, U-shaped valleys with stepped stream gradientsdeep coastal fjordsabsence of deep sediment and short distance to bedrockEven in very cold climates, these features are different from those found in central and northern Alaska, Siberia and Manchuria. We know that central and northern Alaska, eastern Siberia, most of Mongolia, and Manchuria were never covered by glaciers because of such features as V-shaped valleys, concave stream gradients and most importantly the deep sediment in their soils.The reason Siberia, Manchuria, central and northern Alaska, and also the Patagonian steppes, were not glaciated during the Quaternary is simply that they were too dry. Except for the Patagonian steppes, all these regions are even today cold enough for glaciers, but so little snow fell and falls that even with much reduced ablation glaciers cannot develop. (For instance, Barrow receives only 29 inches of snow whereas glaciated Nunavik receives over 100.)In hot regions, soils are so weathered it clear that glaciers could never have formed since the Carboniferous even if there is no deep sedimentation.
Which process led to the formation of thick salt deposits found in the bedrock at some locations in New yORK sTATE?
The thick salt deposits found in the bedrock in some locations in New York State were formed through the process of evaporation of ancient seas that once covered the region. Over millions of years, as these seas evaporated, the salt minerals precipitated out and accumulated to form the thick salt deposits that we see today.

Antarctica is made of frozen what?
Antarctica, the continent, is bedrock and soil. Ninety-eight percent of it is covered, however, by frozen water -- an ice sheet.
My guinnea pig constantly scratches itself and is covered in cuts and scratches. What can I do?
TAKE IT TO THE VET IMMEDIATELY! It might have mites or some other bug bite, so make an appointment with a vet that has someone who specializes with pocket pets!!!

How might land once covered by glaciers look different from places that never had glaciers?
Land once covered by glaciers might have features such as moraines, glacial erratics, and u-shaped valleys, as well as evidence of glaciation in the form of striations and polished bedrock. In comparison, places that never had glaciers may have smoother topography and lack these distinctive glacial landforms.
How do you run damaged discs?
Some don't. The scratches can be covered using a special gel. Or, the disc data can be converted to a working CD disc.
What is evidence that a glacier once covered an area?
u shaped valleys
Does scratching a rental car which is fully covered by the rental company affect your insurance rate?
Rental cars have dents and scratches all over them, but are covered up with a little paint. Maybe they can be dated and traced back to you, maybe not.
What evidence proves that the guards killed duncan?

Which observation is evidence that a unicellular organism is not a eukaryote?
The cell lacks a membrane-covered nucleus.
