What 3 factors determine the characteristics of sedimentary rock?
Regional SpecificsWhat three factors determine the characteristics of sedimentary rocks? The source of sediment, the way sediment was moved and the conditions that sediment was deposited. How are newly formed sediments transported to new locations? They are transported by wind, water or ice. What 3 characteristics determine the type of sedimentary rock? Clastic sediments or sedimentary
What are the 4 ways plates move?
Regional SpecificsWhat are the major plate tectonic boundaries? Divergent: extensional; the plates move apart. Spreading ridges, basin-range. Convergent: compressional; plates move toward each other. Includes: Subduction zones and mountain building. Transform: shearing; plates slide past each other. Strike-slip motion. What are the 4 plate boundaries? There are four main types of plate boundary. These are constructive,
What minerals are in rock dust?

What tectonic plate is Pakistan on?
Regional SpecificsPakistan is split along the boundary between the Eurasian and Indian plates where the India plate slides northward relative to the Eurasia plate in the east. Is Pakistan on the Indian tectonic plate? Pakistan geologically overlaps both with the Indian and the Eurasian tectonic plates where its Sindh and Punjab provinces lie on the north-western
What is isotopic dating used for?
Regional SpecificsRadioactive dating is a method of dating rocks and minerals using radioactive isotopes. This method is useful for igneous and metamorphic rocks, which cannot be dated by the stratigraphic correlation method used for sedimentary rocks. Over 300 naturally-occurring isotopes are known. What does isotopic dating deal with? Isotopic dating of rocks, or the minerals in
Why is pyrite called fool’s gold?
Regional SpecificsPyrite is called “Fool’s Gold” because it resembles gold to the untrained eye. While pyrite has a brass-yellow color and metallic luster similar to gold, pyrite is brittle and will break rather than bend as gold does. Gold leaves a yellow streak, while pyrite’s streak is brownish black. Does pyrite have gold in it? Ironically,
