- 2. Multiple ChoiceThe index fossil of a type of trilobite is discovered in layer A of a set of rock layers found at three different sites of a field investigation. Which conclusion can be made about the rocks in layer A at all three sites?The rocks are all different agesThe rocks are all about the same ageThe rocks were formed from melting magmaThe rocks were formed during a catastrophic event
- 3. Multiple ChoiceFossil remains of a trilobite are most likely to be found in which type of rock?igneousvolcanicsedimentarymetamorphic
- 4. Multiple ChoiceWhich statement best describes the Law of Superposition?Each sedimentary layer of rock represents 1,000 years of Earth's age, much like the rings of a tree.In undisturbed layers of sedimentary rocks, the upper rock layers are older than the lower rock layers.In undisturbed layers of sedimentary rock, the lowest layers contain the older rocks.Rocks that form near volcanoes are older than surrounding rock.
- 5. Multiple Choice
Which statement best supports the inference that most of Earth's present-day land surfaces have, at one time, been covered by water?
Volcanic eruptions contain large amounts of water vapor
Coral reefs formed, in the past, along the edges of many continents
Seafloor spreading has pulled landmasses apart and pushed them together.
Sedimentary bedrock of marine origin covers large areas of Earth's continents.
- 6. Multiple Choice
