Just as the rings on a tree can be used to determine its age, the bands on a bivalve’s shell can tell us the how long it’s been around for. Warm, food-filled waters lead to greater growth in the summer and low plankton abundance (the principle food source for filter-feeding molluscs) leads to limited growth during the winter months – hence the banding. But pinning down the age of a bivalve m ...[Read More]

The water that discharges at Mammoth Hot Springs in Yellowstone National Park is highly alkaline (contains a lot of dissolved CO2) and rich in calcium, but as the water cools, the calcium precipitates to form the white limestone terraces you see here. This limestone is known as tra ...[Read More]
