Fill in the Blanks Sinkoles and LandslidesOnline version Water can change not only landforms on earth´s surface but also features underground. For example, groundwater can weather and erode soft rocks. Undergorund erosion causes caves to form. Often, the roof of a cave collapses due to the weight of material above it. If the cave is near the surface, a large hole, called a sinkhole, may open suddenly. Most skin holes are found where limestone is common, such as in Florida. As you learned water isn´t the only factor that causes erosion and deposition. Gravity can also cause these land-changing processes to happen. Gravity can make soil, mud, and rocks move quickly down a slope. this form of erosion is called landslide. Landslides can happen suddenly, especially after heavy rains or earthquakes. by Clara Villa 1 Gravity erosion limestone landslide underground sinkhole Water surface rocks soil groundwater slope can change not only landforms on earth´s surface but also features .
