Pangaea or Pangea ( /pænˈdʒiːə/) was a supercontinent that existed during the late Paleozoic and early Mesozoic eras. It assembled from earlier continental units approximately 335 million years ago, and it began to break apart about 175 million years ago.
Desertification occurs<span> due to a decrease in vegetation. This can </span>happen<span> naturally due to a drought or can be caused by human activities. The lack of plants can cause changes to the land. Plants help shade the soil, so when plants are removed, the soil will be exposed to the sun and will dry out more quickly. So, I would say C. An area of forest is clear cut.

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 Checking rock age and strata with any historical references could explain.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.
