Question

Quizplus · Accepted Answer

Most of Earth's coastlines are relatively young and undergoing continuous change due to a variety of factors such as sea level rise, erosion, tectonic activity, and human activities like construction and land use changes. Therefore, option A is the best choice. Option B is incorrect as coastlines are shaped by several processes that occur over millions of years. Option C is incorrect as many inputs beyond tidal action, such as storms, tsunamis, and human activities, affect coastlines. Option D is also incorrect as coastlines vary significantly across the planet due to different geological, climatic, and cultural factors.
