Examples of Earth's surface changing in national parks

📚 Quick Study Guide

• 🌋 Volcanic Activity: Eruptions create new landforms quickly (e.g., craters, lava flows).
• 🏞️ Erosion: Water, wind, and ice wear away rocks and soil over time, forming canyons, valleys, and coastlines.
• 🏔️ Glaciation: Glaciers carve out valleys, deposit sediment (moraines), and create lakes.
• 🌊 Coastal Processes: Waves and tides erode coastlines, creating cliffs, beaches, and sand dunes.
• 🌱 Biological Activity: Plants and animals can contribute to weathering and erosion.
• 🪨 Weathering: The breakdown of rocks through physical (temperature changes) and chemical (acid rain) processes.
• 🌍 Tectonic Activity: Earthquakes and plate movement can cause rapid changes to the landscape (e.g., uplift, subsidence).
