What rocks are in the lower mantle?
Natural EnvironmentsThe rocks that make up Earth’s mantle are mostly silicates—a wide variety of compounds that share a silicon and oxygen structure. Common silicates found in the mantle include olivine, garnet, and pyroxene. The other major type of rock found in the mantle is magnesium oxide. What is found in the lower mantle? Silicon and magnesium

How can organisms be preserved?
Natural EnvironmentsFreezing, drying and encasement, such as in tar or resin, can create whole-body fossils that preserve bodily tissues. These fossils represent the organisms as they were when living, but these types of fossils are very rare. Most organisms become fossils when they’re changed through various other means. What are 5 ways organisms can be preserved?

Where is erosion concentrated along a meandering stream?
Natural EnvironmentsWhere do deposition and erosion of material occur along a meander? Deposition occurs on the inside of the meander, whereas erosion occurs on the outside. Where is erosion most dominant in a stream? 1. As suggested above, in response to a streams velocity, a river will tend to erode along the outside of a meander,

How do scientists detect P and S waves?
Natural EnvironmentsP waves can travel through liquid and solids and gases, while S waves only travel through solids. Scientists use this information to help them determine the structure of Earth. For example, if an earthquake occurs on one side of Earth, seismometers around the globe can measure the resulting S and P waves. How do scientists
