What potential consequence can arise from tectonic movements in coastal areas?

Tectonic movements in coastal areas can lead to the creation of new shorelines and habitats due to processes such as uplift and subsidence. When tectonic plates shift, they can cause coastal land to rise or fall. Uplift can expose new land, creating fresh shoreline environments that can be colonized by various marine and terrestrial species, facilitating the development of new ecosystems. Additionally, when coastal areas subside as a result of tectonic activity, it may lead to the formation of estuaries or wetlands, further contributing to habitat diversity. This dynamic process shapes the coastal landscape and influences the interplay between terrestrial and marine ecosystems, making it a significant consequence of tectonic movements in these regions.
