  • What can be used to determine the relative age of two rocks? - Brainly. com
    To determine the relative age of two rocks, one effective method is to examine the presence of unconformities, which is the interruption in the deposition of sedimentary rocks An unconformity can indicate that erosion has occurred at a certain point, leading to different ages of rock layers that are now situated next to each other
  • What can be used to determine the relative age of two rocks? - Brainly. com
    To determine the relative ages of two rocks, geologists often look for certain indicators within the rock layers themselves One key concept is the principle of superposition, which states that in an undisturbed sequence of sedimentary rock layers, the oldest layers are found at the bottom, while the younger layers are located at the top
  • What can be used to determine the relative age of two rocks?
    Scientists can figure out the relative age of the rocks in a number of different ways One way is to use the law of superposition, which says that the bottom layers of geological rocks are usually older than the top layers
  • What can be used to determine the relative age of two rocks?
    To determine the relative age of two rocks, several key principles in geology can be utilized Here are the main methods: Vertical Position : According to the law of superposition, in a series of undisturbed sedimentary rock layers, the oldest layers are at the bottom, and the youngest layers are at the top
  • [FREE] What two methods are used for determining the age of rocks and . . .
    The two methods used for determining the age of rocks and fossils are Relative Dating, which compares the order of layers, and Absolute Dating, which provides a specific numerical age Relative Dating helps establish the sequence of events without exact dates, while Absolute Dating uses techniques like carbon-14 dating for precise ages
  • [FREE] Explain how fossils can be used to determine the relative ages . . .
    How can fossils be used to determine the relative ages of rock layers? A The way a fossil is preserved indicates the exact age of a rock layer B Knowing the age of fossils can allow us to determine the relative age of the rock layers they're found in C The number of fossils found in a rock layer indicates the layer's age D
  • Compare the relative ages of strata in sedimentary rock. - Brainly. com
    Stratigraphy is the study of rock layers, or strata, and is primarily applied to sedimentary rocks The key principle used to determine the relative age of these layers is known as the law of superposition This law states that in a sequence of undeformed sedimentary rocks, the oldest layers are at the bottom, while the youngest are at the top
  • Which one of these is the most accurate in determining the absolute age . . .
    It is helpful in dating age of a rock or fossil Radioactive dating is a type of absolute aging or dating process This method configures the organic and inorganic materials present in the material to determine the age of the material Hence, radioactive dating of each layer can be the most accurate in determining the absolute age of two rocks
  • What can be used to determine the relative age of two rocks? question . . .
    The relative age of two rocks can be determined by: radioactive dating of each layer Radioactive dating is the method of determining the age of rocks or minerals using the radioactive substances The method is very useful for determining the age of igneous and metamorphic rocks whose dating cannot be done using any other method
  • [FREE] Which is true about radiometric dating? A. It is used to . . .
    a Scientists use radiometric dating to determine the relative age of a new fossil b Scientists use relative dating to determine the absolute age of a new fossil c Scientists use radioactive isotopes to determine the absolute age of a new fossil d Scientists use index fossils to determine the specific years of age of a new fossil
