Use the passage to answer: Which scientific theory was supported by this evidence?
the theory of spontaneous generation, which states that matter can form and appear anywhere
the big bang theory, which states that at one point the universe was one confined to a single point
the continental drift theory, which states that all of the continents were once joined together and drifted apart to their current locations
the expanding Earth theory, which states that the position and movement of continents is dependent on the volume of the planet increasing
Index fossils are used to date rock strata that would otherwise be very difficult to date. Which of these statements describes a key characteristic of index fossils?
They existed in a unique location
They are present in very small numbers.
They existed for a short span of time.
They are similar to other fossils
According to the law of superposition, which of the following is true about the layers in location 2?
Layer Z has the darkest color, so it must be the oldest, and layer X has the lightest color, so it must be the newest.
Layer Z has the largest fossils, so it is the oldest, and layer W has the fewest fossils, so it is the newest.
Layer W is on the top, so it is the newest, and layer Z is on the bottom, so it is the oldest.
Layer Z is on the bottom, so it is the newest, and layer W is on the top, so it is the oldest
What is the method of measuring age that gives the most precise results?
radioactive dating, when scientists measure the levels of an isotopic element inside of an object
relative dating, when scientists fill an object with carbon and measure how much will fit
rate of sedimentation, which dates layers of Earth based on their thickness
law of superposition, which dates layers of Earth based on their order
Scientists think the continents once formed a large, single landmass that broke apart and the continents slowly drifted to their present locations. What is the name given to this hypothesis?
Continental rise
Continental drift
Continental shelf
Continental slope
At one time, several kinds of camels lived in Florida. The evidence comes from fossils found in Florida. Which of these objects would be a fossil that shows that camels once lived in Florida?
Sinkhole formed by a retreating glacier
sedimentary rock that formed a long time ago
crystal formation suspended from the ceiling of a cave
remains of an organism preserved by geologic processes
Mountain ridges form and later become eroded, at which point an igneous intrusion rises under the mountains. What does the presence of the igneous intrusion indicate about Earth's history?
Volcanic material cannot be used to date either mountains or volcanoes
Volcanic material can be used to date only mountains
Volcanic material can be used to date only volcanoes.
Volcanic material can be used to date both mountains and volcanoes.
In Canada, Mount Rundle is an example of thrust faulting where millions of years ago a plate collision forced horizontal layers of an ancient ocean crust up at a steep angle. This formed a mountain with one side gently sweeping and full of trees, while the other side is steep with exposed rock. What is Mount Rundle evidence of?
Earth's evolution over time due to natural processes
Earth's evolution over time due to supernatural processes
Earth's evolution over time due to organismal interference
Earth's evolution over time due to natural disasters
