multiple choice question\necho charts can be used to study the properties of the seafloor because \n\nthe charts include a chemical analysis of the seafloor at the point of reflection\nthe charts provide photographs of the materials\ndifferent rocks and sediments reflect signals differently
Answer
Brief Explanations:
Echo - charts work on the principle of signal reflection. Different rocks and sediments on the seafloor have distinct physical properties that cause them to reflect sound or other signals differently. This allows scientists to infer properties of the seafloor. Echo - charts do not provide chemical analysis or photographs.
Answer:
C. different rocks and sediments reflect signals differently
