What effect does erosion have on rock features over time?
It causes rock features to become larger and sharper over time.
It causes rock features to become more rounded and broken down over time.
Erosion does not impact rock features at all.
What is gravity's role in erosion?
Gravity provides the force necessary for mass movement like landslides.
Gravity provides the medium through which sediment can flow (rivers, etc.).
Gravity constructs new landforms, such as sand dunes and sea arches.
Gravity provides the force that folds mountains and causes weathering.
Which fossil the best index fossil for the time depicted in these three geologic columns?
Fish fossil
Braciopod fossil (looks like a flat shell)
Gastropod (looks like a spiral shell)
What is the condition for a good index fossil?
appears in only one geologic column (location).
appears in multiple geologic columns (locations).
What is the condition for a good index fossil?
the fossil appears in only one layer of rock (short-lived).
the fossil appears in multiple layers of rock (long-lived).
A good index fossil cannot be in a layer of rock with other fossils...like in the picture.
True
False
The Law of Superposition states that in any undisturbed sample of sedimentary rock, the...
youngest rock is found at the top of the rock sample.
youngest rock is found at the bottom of the rock sample.
sedimentary rock doesn't fall in layers.
rocks form in layers from the middle outward.
How do weathering and erosion impact sedimentary rock and landforms?
they build up landforms because they are constructive forces.
they break down landforms because they're destructive forces.
they do not affect landforms at all.
Read the question in the picture. Select the correct answer.
A
B
C
D
The oldest feature/layer is ____ and the youngest feature/layer is ____.
E/A
E/C
C/E
D/E
What evidence supports that the igneous rock intrusion D is younger than rock layer B?
igneous rocks are always younger than other rocks.
the igneous rock isn't younger than rock layer D-no evidence.
intrusion D is below rock layer B so it is younger.
intrusion D cuts across rock layer B; so it much be younger.
