What is the study of waves from earthquakes has helped scientists understand the interior layers?
siesmology
Can scientists know where past earthquakes were?
By looking at the rocks and the way the layers of rock are stacked scientist feel they have pretty good idea of the time and severity of many past earthquakes.
How can scientist tell earthquakes occurred before records were kept?
Shifts in geological layers on different sides of a fault...
Diffrenciate geologic time with geologic column?
Geologic column is an ordered arrangement of rock layers that is based on the relative age of the rocks. Geologic time is the time IN the geologic column.
Explain how scientists use the law of crosscutting relationships to determine the relative ages of rock layers and a fault that cuts through the layers?
well love is a boy and a girl together ...........like meh3>
Could you tell the relative age of a fossil if layers of rock have been shifted by earthquakes?
yes
Could you tell the relative age of a fossil if layers of rock have been shifted by earthquake?
it cool
How the relative age of a fossil is determined by studying layers of rock?
It is determined because in layers of rocks the fossils are found so the layers of rocks give information to the scientist about the age of a fossil so like that the relative age of a fossil is determined.
Why can relative dating be used only to estimate the age of a fossil?
by comparing its placement with that of fossils in other layers of rock
Which characteristics of a fossil would you make it useful as an index fossil in determining the relative age of widely separated rock layers?
C). a narrow time range and a wide geographic range
What is the method of determining whether a fossil is older or younger than other fossils found in the many layers of sedimentary rock is called what?
relative dating
Do sedimentary rock layers always stay horizontal?
No. It is not uncommon for the layers to be shifted out of a horizontal position.
How relative dating works?
Relative dating is how scientists determine how old a species is by looking at the undisturbed layers of rock. The deeper down the layer is the older the fossil is. (:
What causes rock layers to be displaced?
Earthquakes
What are disturbed rock layers associated with?
earthquakes
A fossil that is found in the rock layers of only one geologic age and that is used to establish the age of the rock layers?
An index fossil.
A fossil that is used to date surrounding rock layers is?
This is called an index fossil.
