What role do faults play in the Law of Superposition?
Faults create new types of rock.
Faults are younger than the layers they cut through.
Faults are the same age as the layers they cut through.
Faults are older than the layers they cut through.
The type of Earth material most likely to contain fossils is:
igneous rock
metamorphic rock
sedimentary rock
native material
Scientists find dinosaur fossils in the bottom rock layers of a cliff and mammal fossils in the middle rock layer of the cliff. Which could best be concluded from this evidence?
Dinosaurs ate plants.
Dinosaurs were eaten by the mammals.
Dinosaurs lived on Earth before the mammals.
Dinosaurs and mammals lived at the same time.
When two fish die, Fish A sinks to the bottom of a lake and Fish B washes up on the rocky lake shore.
Why is a fossil more likely to form from the body of Fish A than from the body of Fish B?
Soft parts of the fish will decay more quickly in the water.
Sediments in the water will quickly cover the fish
Scavengers in the water will eat the remains of the fish.
Currents in the water will move the fish.
What are strata?
inconsistencies in the fossil record
rock layers
well-known and widespread fossils
units of time
