Accurate measurements have been collected for more than a century.
Answer:
Fine-grained extrusive igneous rock
Explanation:
The andesitic sample is a fine-grained rock formed from stratovolcanoes. It solidifies quickly on reaching the surface. It is an intermediate sample between basalt and granite. It is an extrusive igneous rock. They have relatively high aspect ratio which implies that it is thick and advances only short distance down the volcano edges.
Beaches are more vulnerable to erosion because of destructive waves which erode the sediments
The combination of the weathering and erosion of the stream bank and the cutting into the bedrock from the velocity of the stream combine to make a "stream valley".
<h3>
What is stream valley?</h3>
A stream valley is an earthen dip where water is present at its lowest point. These valleys are the result of erosion, which is the transfer of decomposed rock or soil from one location to another.
The formation of stream valley is given below-
- The typically V-shaped stream valley is changed to a U-shaped valley because the U-shape offers the flowing glacier the least amount of frictional resistance.
- Because a glacier's cross section and viscosity are substantially greater than those of a river, its route has fewer and wider bends.
