When the landmasses are again collected together in a specific area

The Pangea theory supports the theory of plate tectonics because it is based on the idea that all the present continents were one super-continent. For reasons still unknown, the super-continent got separated and created separate smaller continents. This theory also supports the fact that this movement will continue until the day arrives when all the smaller continents will again merge in a different configuration to create another super-continent.

Answer:

A. Populations of native wetlands plants will recolonize the land.

Explanation:

From many years' wetlands are converted into farmlands as they provide retention of soil, proper food and clean water, and the cycling of nutrients. But wetlands should not be permanently converted because it can increase the load on soil and add pollutants (pesticides or fertilizers) in the soil and groundwater.

If the farming stops and water flows on the land again, the native plants present in wetlands will help to recolonize the land which is disrupted by farming activities.

Hence, the correct option is A.
