Stratigraphy - Layers of Earth
Stratigraphy On Morro Rock Morro Rock @ Morro Bay CA The erosion that exposed the layers was most likely caused by natural weathering processes, including wind, water, and wave action, which gradually wore away the softer surrounding rock to reveal the harder volcanic plug. The layers appear to be similar, indicating they are likely composed of the same or similar types of rock/material. This similarity suggests a consistent volcanic process that deposited layers of ash, lava, and volcanic debris over time. We can greatly assume that these layers were created by successive volcanic eruptions that deposited ash, lava, and other volcanic materials because of its passed activity with frequent eruptions, lava flows, and ash falls. The creation of all the layers likely spanned millions of years, with each volcanic event contributing to the buildup of the layers. Isabella Uhlik Morro Rock - May 27th, 2024
