Which types of soil are susceptible to liquefaction in an earthquake?
GeologyPoorly drained fine-grained soils such as sandy, silty, and gravelly soils are the most susceptible to liquefaction. Granular soils are made up of a mix of soil and pore spaces. When earthquake shock occurs in waterlogged soils, the water-filled pore spaces collapse, which decreases the overall volume of the soil. What areas are susceptible to

It was caused not by lava but by the towering walls of sliding mud created when large chunks of hot ash and pumice mixed with melted snow. What was the damage of Nevado del Ruiz? The lahars destroyed everything in
How are mineral replacement fossils formed?
GeologyFossils form through the process of mineral replacement beginning when an organism dies and is buried. Groundwater seeps around the organism, and the minerals in the water gradually replace the minerals in the hard parts of the organism. Over time these minerals turn into a stone replica of an organism. How are replacement fossils formed?
