Sedimentary rocks are one of the three main types of rocks found on Earth, along with igneous and metamorphic rocks.They are formed through the accumulation, compaction, and cementation of various sediments over time. Sediments are fragments of rocks, minerals, organic material, and even chemical precipitates that have been weathered …

The crust is the thinnest layer in the earth, making up only 1 percent of the mass and 2 percent of the volume. Relative to the rest of the earth, the crust is rich in elements such as silicon, aluminum, calcium, sodium and potassium. Crustal materials are very diverse, consisting of more than 2000 minerals.

Rocks are classified based on how they were formed. The three major types are igneous, sedimentary, and metamorphic rocks. This classification is essential to geologists as it provides critical information about the history of specific regions on Earth. These rocks change forms via the rock cycle.

Many of the real creatures whose bones became fossilized were no less marvelous than the mythical creatures they inspired (Figure 11.3). The giant pterosaur Quetzalcoatlus had a wingspan of up to 12 meters (39 feet). The dinosaur Argentinosaurus had an estimated weight of 80,000 kg, equal to the weight of seven elephants! Other fossils, such as the …

Most fossils form when a dead organism is buried in sediment. Layers of sediment slowly build up. The sediment is buried and turns into sedimentary rock. The remains inside the rock also turn to rock. The remains are replaced by minerals. The remains literally turn to stone. This type of fossilization is called permineralization. …

Due to friction, to bend the strata, all inside layer is under the action of a pair of forces, one of which (on the roof of the layer) is directed towards the anticlinal dome. The other (in the wall layer) is directed to the hook of the syncline. This torque tends to cause a deformation in the displacement layer. Types of Geological Folds
