1. Are bedrock channels more likely to be found near the head or near the mouth of stream?
Bedrock channels are more likely to be found near the head of a stream where the gradient is steeper and erosion processes are more active. As the stream flows downstream and the gradient decreases, the likelihood of encountering bedrock channels decreases as well.
A fossil that is likely to be found in the same age bedrock as Centroceras is a marine organism such as other types of algae, foraminifera, or marine invertebrates like brachiopods or ammonites. These organisms lived in similar environments and time periods as Centroceras, making them common in the same age bedrock layers.
Aquifers are typically found below the bedrock. Bedrock acts as a barrier that holds the water in the aquifer, with layers of soil, sand, and gravel above the bedrock helping to recharge the aquifer with water.
A resurgent stream is formed when an underground river is forced to reappear when it reaches a layer of impermeable bedrock. For a river to become an underground river in the first place it must flow over an area of limestone rock. The mildly acidified river water (it is acidified by dissolved carbon dioxide which is present in rainwater) reacts with the limestone (which is 80% calcium carbonate) and dissolves it. This forms a swallow hole into which the river flows. The river then continues to chemically weather the limestone underground thus forming an underground river. The river is forced to reappear (in the form of a resurgent stream) on the surface when there is a change of rock type from permeable limestone to impermeable bedrock. Hence resurgent streams are typically only found in limestone areas.
Unweathered bedrock is typically found in the bedrock layer of the Earth's crust, which is known as the lithosphere. This layer is located beneath the soil, regolith, and weathered rock layers.
Bedrock channels are more likely to be found near the head of a stream where the gradient is steeper and erosion processes are more active. As the stream flows downstream and the gradient decreases, the likelihood of encountering bedrock channels decreases as well.
The processes most likely formed a burial and compaction which the shale bedrock is found near Ithaca, New York.
The efflux of potassium ions is maintained by passive potassium channels.

A chalk stream is a type of river or stream that flows over chalk bedrock or through chalk hills. These streams are known for their clear, alkaline water and are usually rich in flora and fauna. Chalk streams are found mainly in southern England.
There is not a specific type of bedrock found along the rocky shores. The types of bedrock found depend on the ecosystem at the different rocky shore sites.
everyone, the answer to this question is burial and compaction
Assuming you are not referring to the 'Flintstones - town of Bedrock' and are referring to geological bedrock then any rock that is not part of the soil or an erosional clast (of any size) is bedrock. Bedrock is therefore found everywhere.
Aquifers are typically found below the bedrock. Bedrock acts as a barrier that holds the water in the aquifer, with layers of soil, sand, and gravel above the bedrock helping to recharge the aquifer with water.
in the tug hill plateau
yes example:I dug really deep and found the bedrock beneath the soil.
