it is impossible for a piece of the Martian surface to fall to Earth.
d.
both a and b are true.

Which statement would a scientist most likely offer to explain this situation? A.) The fish in the lower layer lived in the deep sea. While the other fish lived in shallow water. B.) The fish in the upper layer lived a healthier life than the other fish. C.) The rock in the lower layer is denser than the rock in the upper layer D.) The rock in the upper layer must have formed in freshwater E.) The fish in the upper layer lived more recently than the other fish.

- Earth is about 4.5 billion years old. In order to characterize the events that happened in this very long time scale, scientists have developed the geologic time scale. Here, the age of Earth is divided into (1), which in turn divided into (2), and are further subdivided into (3). The geologic time scale is so-called since the different subdivisions are based on the fossil record.arrow_forwardDuring the Paleozoic, many life forms developed hard parts (shells/bones/etc.). Why would it be useful for organisms to have hard parts?arrow_forwardIn radiometric dating, scientists use the half-life of a radioactive isotope, to determine the approximate age of rocks, and the fossils that are embedded in them. Half-life is the time it takes for half of a radioactive element to become stable.Uranium 238 (238U) is a radioactive element that decays into Lead (206Pb) after 4.5 billion years. 6) Scientists found a fossil in a layer of rock that tested as 1/8th U and 7/8th Pb. What is the approximate age of the fossil? A) 562 million years old B) 4.5 billion years old C) 9 billion years old D) 13.5 billion years old Not Gradedarrow_forward
