Final answer:
Geological processes like plate tectonics, erosion, and volcanic activity have changed Earth's surface over the years.
Step-by-step explanation:
Geological Processes and Earth's Surface Changes
Over the years, various geological processes and interactions have significantly changed the Earth's surface. One such process is plate tectonics, which involves the movement and interaction of Earth's lithospheric plates. This movement has led to the formation of mountains, ocean basins, and other landforms. For example, the collision of two continental plates can result in the uplift of land and the formation of towering mountain ranges like the Himalayas.
Another key geological process is erosion, which is the wearing away of Earth's surface by natural forces such as wind, water, and ice. Erosion can reshape coastlines, carve out valleys, and create canyons over time. The Grand Canyon is a remarkable example of how erosion over millions of years has shaped the Earth's surface.
Volcanic activity is yet another process that has molded the Earth's surface. When molten rock (magma) erupts onto the surface, it can form mountains, islands, and volcanic features like lava flows and calderas. The Hawaiian Islands are a prime example of how volcanic activity has created a series of islands over time.
