Trace fossils
Permineralized fossils
Preserved fossils
Carbon film
Preserved fossils can be found in all of the following types of materials except for -----.
Ice
Tar

Wood
All of these things make the best index fossils except for ---.
Fossils that lived for a short period of time
Fossils that lived in many time periods
Fossils that are widespread
Fossils that are unique
This is an image of the female wooly mammoth that was found in Siberia frozen for thousands of years. This wooly mammoth is what kind of fossil?
Mold fossil
Cast fossil
Preserved fossil
Permineralized fossil
Based on this diagram, what fossil is the youngest?
Early horses
Dinosaurs
Armored fish
Trilobites
Fossil evidence has mainly been used to do what?
Explain how the Earth's environment is currently
Subdivide geologic time into units or periods
Identify unconformities in rock layers
Explain catastrophic events that have happened in the past and today
This diagram shows a cross section of rock layers. Which geologic event happened the most recently
C
F
D
E
In an undisturbed sedimentary rock layer, which layer would be the oldest?
A
C
D
E
A team of Scientist discovered a trail of dinosaur tracks and were able to calculate how fast the dinosaur could walk. What type of fossil is this?
Mold fossil
Cast fossil
Trace fossil
Carbon film
Which layer of rock in this cross section represents an intrusion?
C
F
Z
E
In what order were these layers of rock deposited over time?
A, B, C, D, E
C, B, A, D, E
C, D, B, A, E
D, C, B, A, E
What is the relative age of the igneous intrusion?
The igneous intrusion is younger than layer E
The igneous intrusion is older than layer E
The igneous intrusion is the same age as layer C
The igneous intrusion is older than layer F
Compare the relative ages of these rock layers.
The trilobites are younger than the dinosaurs
The trilobites are older than the early horses
The early horses are older than the dinosaurs
The armored fish are younger than the early horses
A team of scientist discovered a fossil that was formed when an organism was buried by sediment and changed into rock. The organism decayed and left an impression of its shape in the rock that was filled with sand and mud before hardening. What type of fossil did these scientist discover?
Cast fossil
Mold fossil
Petrified fossil
Preserved fossil
What type of fossils are unique, lived for a short amount of time, and many of the organisms can be found in rock layers?
Petrified fossils
Index fossils
Trace fossils
Carbon film
What type of fossil is formed when water and minerals soak into buried remains in sediment, replacing the remains and crystalizing them changing them into rock?
Why were jellyfish an uncommon fossil?
They evolved in very small numbers and were rare to find
They have soft body structures that tend to decay leaving no traces after decomposition
They have tiny bodies and were difficult to find after decomposition
They died in swamps and the acid in the water caused the remains to decay
Many fossils that probably lived in the ocean were found in a mountain range. What can be concluded regarding the place in which these fossils are found?
The mountains were once covered by the sea at some point in the past
The mountains were once covered by glaciers at some point in the past
The mountains were once covered by desert land at some point in the past
The mountains were dry and cold in the past
How are volcanic ash deposits useful to geologist?
It shows when an unconformity might have occurred
Serve as a geologic time marker
Serve as an indicator of mass extinctions
Date catastrophic geologic events
What could have caused diversity of mammals and larger mammals to appear in the Paleogene period?
Evolution of humans
Appearance of the first flowering plants
Extinction of the dinosaurs
Appearance of the first vascular land plants
What do fossils preserved in ash deposits reveal about the Earth's past?
There were massive volcanic eruptions in the past
There were more aquatic organisms in the past
The climate was changing from hot to cold in the past
The area was once a part of a mountain range
Pieces of rock and a huge crater were discovered in the Yucatan peninsula. It is believed this discovery was from the giant asteroid that struct Earth almost 65 million years ago. What did this catastrophic event cause?
The ocean levels to rise covering the entire Earth with water
Caused the start of a series of volcanic explosions
Caused a mass extinction of many life-forms at the time
Caused all of the continents to collide to form one large landmass called Pangea
A student studies the geologic time scale and concluded that the dinosaurs became extinct due to humans. Why is the student's claims wrong?
Dinosaurs suddenly evolved into aquatic animals leaving the land for the sea
Dinosaurs died due to the loss of food sources during the Jurassic Period
Dinosaurs evolved into humans after the Cenozoic Era began
Dinosaurs did not exist at the same time as humans according to the time scale
The Law of Superposition helps Scientists determine what?
The absolute age of rock layers
The species in which a fossil is closely related to
The age of a fossil in comparison to other fossils
The diet of most organisms by looking at their fossils
Scientists use radioactive dating to measure ---.
relative time
absolute time
half-lives
time of day
Scientists chose where units of geologic time began and ended based on the appearance or disappearance of life.
true
false
What type of event usually marks the end of an Era
A Mass Extinction
A Quinceanera
An earthquake
A Volcanic Eruption
