Where does most of our knowledge about the Earth come from?
Regional SpecificsMost of our knowledge of Earth’s interior comes from the study of earthquake waves. How do we get knowledge about the interior of the earth? Scientists are able to understand Earth’s interior by studying seismic waves. These are waves of energy that travel through Earth, and they move similarly to other types of waves, like
What are the different types of tephra?
Regional SpecificsClassification Ash – particles smaller than 2 mm (0.08 inches) in diameter. Lapilli or volcanic cinders – between 2 and 64 mm (0.08 and 2.5 inches) in diameter. Volcanic bombs or volcanic blocks – larger than 64 mm (2.5 inches) in diameter. Which of the following are types of tephra? For example: Ash tuff –
What are the factors do the damage earthquakes cause depend on?
Regional SpecificsWhen an earthquake strikes, the intensity of earthquake shaking determines the severity of damage. In turn, the main factors affecting earthquake shaking intensity are earthquake depth, proximity to the fault, the underlying soil, and building characteristics—particularly height. What are the factors that cause earthquakes? The tectonic plates are always slowly moving, but they get stuck
What is a example of geology?
Regional SpecificsAn example of geology is the study of rocks and stones. An example of geology is learning about how the Earth was formed. The structure of the earth’s crust in a given region, area, or place. The structure of a specific region of the Earth, including its rocks, soils, mountains, fossils, and other features. What
What is clastic texture?
Regional SpecificsClastic texture: grains or clasts do not interlock but rather are piled together and cemented. Boundaries of individual grains may be another grain, cement or empty pore space. Overall rock is generally porous and not very dense. What is an example of a clastic? Clastic sedimentary rocks form from the accumulation and lithification of mechanical
Are subduction zones convergent or divergent?
Regional SpecificsConvergent boundaries (subduction zones) Are subduction zones convergent? Subduction zones are where the cold oceanic lithosphere sinks back into the mantle and is recycled. They are found at convergent plate boundaries, where the oceanic lithosphere of one plate converges with the less dense lithosphere of another plate. Can subduction zones be divergent? Therefore, divergent double
