Answer: Volcanoes form at B when the oceanic plate is subducted, and the plate melts and forms magma. This magma rises towards the surface and erupts as lava which forms the volcanoes. It can be found in Pacific Northwest in northern CA, Oregon and Washington. The boundary in B shows converging plate boundary. An oceanic plate collides with a continental plate. The result is the oceanic plate sinks below a deep ocean trench into the mantle. The boundary shown in A is a diverging plate boundary. 2 oceanic plates diverge to form a mid-ocean ridge.
Exceptions to A and B are when volcanoes form at hot spots in the middle of continental or oceanic plates. Magma melts through the crust and moves to the surface in a hot spot. Also a collision between two oceanic plates can form volcanoes. One of the oceanic plate is subducted which melts the plate and the formation of magma which erupts to form a chain of volcanic islands called an island arc.
Explanation: I took the test and aced it so i hope this helped
The area surrounding big bear lake accurately described by the statements: Cretaceous or Jurassic quartz monozite is found to the west of the lake, Well-dissected alluvial fan deposits are found to the east of the lake, Many faults are found to the north and east of the lake.
Option: A,B &D
Explanation:
According to the gelogical time period Cretaceous and Jurassic period belong to Mesozoic era. Big bear lake was formed during that time. So the mineral quartz, monozite sand found in the west of the lake.
Alluvial fan is formed by the river in its lower course when velocity goes down and all the transported sediments deposited in the foothill zone forms fan shaped land feature known as alluvial fan.Many faults that created by tensional force on the earth's crust found to the north and east of the lake.
