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.
I think the answer is B: sediments melt deep beneath the Earth's surface.
Answer:
Explanation:
Ans 1) The approximate elevation of wonderland lake is about 5500 feet, because it lies in the vicinity of the ridge where peak are having contour values upto 6600 feet and the wonderland lake lies on the lower contour of near about 5500 feet.
Ans 2) The peak elevation of poorman hill is 6485 feet as it can easily seen in the map that the highest contour value us 6485 feet. Poorman hill is lying in this contour value.
Ans 3) It is clearly seen and observed from the map that the elevation of the poorman hill is about 6485 feet where as the elevation of the boulder creek present at the south of poorman hill is less than 6000 feet. Thus poorman hill has higher elevation as compared to bank of boulder creek.
