Examples of geological changes on Earth

📚 Quick Study Guide

• 🌋 Volcanism: The process of magma rising to the Earth's surface, leading to volcanic eruptions and the formation of volcanic landforms.
• ⛰️ Tectonic Activity: Movement of the Earth's plates, causing earthquakes, mountain building (orogeny), and the formation of rift valleys.
• 🌊 Erosion: The wearing away of the Earth's surface by natural agents like water, wind, and ice. This includes processes like weathering, transportation, and deposition.
• 🧊 Glaciation: The process by which glaciers form and move, carving out landscapes and depositing sediments (moraines).
• 🌍 Sea Level Changes: Fluctuations in the global sea level, caused by factors like glacial melting, thermal expansion of water, and tectonic activity.
• ⏳ Time Scales: Geological changes occur over vast timescales, ranging from rapid events like earthquakes to slow processes like mountain erosion.
• 🌱 Biological Activity: The influence of living organisms on geological processes, such as the formation of sedimentary rocks by marine organisms or the weathering of rocks by plant roots.
