Weathering and Erosion.
🎯 Your mission
Predict it first. Then prove yourself right (or wrong).
⚡ The twist
Today's mountain was yesterday's ocean floor.
Mind = Blown
🌋 There are 1,500 active volcanoes on Earth right now.
Make a hypothesis first
Guess: where will the water go first?
What You'll Learn
Caves form when slightly acidic water dissolves limestone over thousands of years. Stalactites hang from the ceiling and stalagmites grow from the floor as minerals are deposited.
