The last option: over tens of millions of years, the giant supercontinent Pangaea began to slowly drift apart forming the continents
Answer:
The correct answer is "altering the equilibrium of ecosystems".
Explanation:
Ecosystem have a very complex and sometimes intricate equilibrium. Each species in an ecosystem have a role in the food chain, therefore, if humans affect the behavior of one species, undoubtedly, another species will be affected. In this case, insect populations are increasing as a result of birds modifiying they migratory behavior due to the presence of discarded food in the landfills. Most likely the increased insect populations will affect the plants population as well, creating a series of events that alter the equilibrium of the ecosystems.
Wegener supported his theory by means of demonstrating the Pangaea and geological similarities among continents. South America and Africa contain fossils of animals observed simplest on the ones two continents, with corresponding geographic levels.
Pangaea Wegener was satisfied that every one of Earth's continents have been as soon as a part of a good-sized, single landmass referred to as Pangaea. Wegener, educated as an astronomer, used biology, botany, and geology to describe Pangaea and continental drift.
The rock formations of eastern North the USA, Western Europe, and northwestern Africa were later found to have a not unusual starting place, and they overlapped in time with the presence of Gondwanaland. together, those discoveries supported the life of Pangea.
Wegener showed that positive styles of rocks on the continents would match with others in some other continents. What did Wegener realize approximately the oldest rocks on the African and South American continents? That they had been connected collectively whilst the continents were arranged to shape Pangaea.J
