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.
Answer: 2) secondary succession
Explanation:
Ecological succession is the change in the biotic community of the ecosystem due to the changes occurring in the abiotic components such as water, soil, atmosphere and others. These changes occur with respect to time until the ecosystem attains the stability.
A secondary succession can be define as the changes which occur after a catastrophic event or ecological disturbance. Such changes brings stability with the help of precursors of previously existing species at the same place.
According to the given situation, secondary succession could have occurred this is because of the fact that the forests fire can burn the vegetation in an area. The burn sites will regrow into a healthy forests because of some of the precursors of previously existing plant species like seeds, stem, roots and others which will help in regrowth of new plants.
