read the passage and answer the following question(s).\ndating rock strata\nscientists can determine the age of rock layers by measuring radioactive elements within the rock. radioactive elements found in sedimentary rocks decay quickly, so this method can only date sedimentary rocks that are less than 50,000 years old. volcanic rock layers have radioactive elements that decay very slowly, so scientists can date volcanic rocks that are much older than 50,000 years.\na team of scientists is investigating a rock formation found in a region. the diagram shows the rock formation that the scientists are investigating.\nhow can volcanic rock layers be used to learn more about a location?\na. they can be used to determine the exact ages of the fossilized organisms.\nb. they can be used to determine the periods between future eruption events.\nc. they can be used to determine the exact dates of the sedimentary rock layers.\nd. they can be used to determine the time periods before and after eruption events.
Answer
Brief Explanations:
Volcanic rock layers can provide information about past volcanic - related events. They can help in understanding the time periods before and after eruption events. Radiometric dating of volcanic rocks is mainly for determining their own age and not for exact ages of fossilized organisms in sedimentary rocks (A is wrong), nor for predicting future eruption events precisely (B is wrong), and not for determining exact dates of sedimentary rock layers (C is wrong).
Answer:
D. They can be used to determine the time periods before and after eruption events.
