Cave Weathering & Erosion

Cave Weathering & Erosion

Dive into cave weathering and erosion! Caves are hollow spaces underneath the earth’s surface with openings large enough for a person to enter. Many caves form in a karst environment, a type of landscape made of rocks like limestone, or dolomite, that slowly dissolve in the presence of water with a slightly acidic tinge. There are several different types of caves, and they are named by how they are formed. The most common type of cave is a solutional cave, a cave formed by the chemical reaction of water with limestone bedrock. While chemical weathering gets things started, caves continue to develop over time through ongoing physical and chemical weathering, as well as erosion.

Meteorology

Today’s podcast focuses on the field of meteorology and the forces that create weather patterns and natural phenomenon like rain, thunder, and lightning. The kids discuss and explain how the weather is predicted and how it affects our everyday lives. Weather changes can be caused by temperature shifts that affect our atmosphere and cause the air to move differently. A meteorologist is someone who studies and predicts weather patterns and helps us understand what is going on in our atmosphere.
