Answer:
Sand dunes and strong winds (~90 mph)
Explanation:
Primary succession occurs in lifeless areas. That eliminates lava flow and bare rock. Sand dunes are also formed by this mode.
Secondary succession occurs in areas where an existing ecology has been wiped out by some disaster, such as a blowout in a dune.
A blowout is a steep sided valley in a sand dune caused by strong winds. They blow the beach sand inland and cover up existing vegetation, so the stages of succession must begin anew.
Answer:
By a mix of human and physical geographic evidence.
Explanation:
Civilizations can end due to natural causes. Volcanic eruptions can be devastating for people living close to it. Checking rock age and strata with any historical references could explain. Data from ice core could indicate changes in the atmosphere. A change, such as increased drought, in regions, might end up causing food shortages and the end of civilizations.
Human evidence can provide the answers too. Migration patterns may explain this, such as the Europeans arrived in the Americas. The land has a carrying capacity. Studying the population might indicate the carrying capacity was exceeded, such as Easter Island.
