Adaptations of Cave Critters
Caves with the National Natural Landmark (NNL) designation are some of the most fascinating of the thousands of caves around the world, and each one is unique. Caves’ special features are the product of various types of rock, their geologic setting, local climate, and time. This diversity in cave environments provides unique habitats for many different species of plants, animals, and other types of organisms. Each organism has developed specialized adaptations to survive in these cave environments.
Making Caves: How Solution Caves Form
Caves form through a variety of natural processes depending on their local geology and climate. Flowing lava, melting ice, dissolving rock, and crashing waves are the major processes that form these wondrous environments. In this activity, students will observe a model of how the most common type of cave — solution caves — form.
Per student or small group:
• 4 ounces of modeling clay
• Sugar cubes (3-6 per cave)
• See-through bowl (cutting the top off a 2-liter bottle works well)
