Answer:
About 3500 meters of summit of a composite volcano collapsed after an explosive eruption of about 500 cubic kilometers of pyroclastic material. Later the caldera was eventually filled with water.
Explanation:
Crater Lake is one that is found to occupy a basin in Mount Mazama in south-central Oregon in the western United States. Mount Mazama, which is about 12,000 ft (roughly 3,700m) collapsed during an intense volcanic eruption, which led to the formation of volcanic depression called caldera.
Pyroclastic flows of pumice and ash affected the nearby areas which also included the water body that drained the mount Mazama.
Answer:
transform plate boundary
Tectonic setting of the San Andreas Fault (transform plate boundary) in California, the subduction zone (convergent plate boundary: oceanic-continental collision) in the Pacific Northwest.
Landslides along cut banks are common; a landslide along a cut bank affects the discharge of a river because the landslide the discharge would increase because the cross-sectional area of the river would increase.
Landslides are resulting from disturbances in the herbal stability of a slope. They are able to accompany heavy rains or comply with droughts, earthquakes, or volcanic eruptions. Mudslides broaden while water rapidly accumulates in the ground and results in a surge of water-saturated rock, earth, and debris.
The cross-sectional area is the place of a -dimensional form that is obtained while a three-dimensional item - which includes a cylinder - is sliced perpendicular to some special axis at a factor.
Cut banks are caused by the moving water of the river sporting away the earth. A factor bar then again is placed on the interior of a bend in a river (meander). Because the river curves around the bend within the river, the water slows down and sediment is dropped to the river bed.
