Rock layer A is inferred to be older than intrusion B because

parts of layer A were altered by intrusion B

When did the folding of rock layer B most likely occur?

after the deposition of rock layer C

Which is the best explanation for the irregular surface between layers 1 and 2?

Layer 1 was partially eroded before 2 was deposited.

Corals are found in warm seas. Coral fossils have been found in the sedimentary rocks of Alaska

Alaska once had a tropical marine environment

Why is layer 4 likely to be a good time marker?

Volcanic ash is usually rapidly deposited over a largearea.

Utica and Binghamton
Plattsburgh and Watertown
Jamestown and Rochester
Syracuse and Albany
4
Rock layer A is inferred to be older than intrusion B because

layer A is composed of sedimentary rocks
parts of layer C were altered by intrusion B
parts of layer A were altered by intrusion B

When did the folding of rock layer B most likely occur?
after the deposition of rock layer C
after the deposition of rock layer E
after the deposition of rock layer D
before the deposition of rock layer A
7
Fossils are least likely to be found in which rock?
D
F
E
C
8
Unless a series of sedimentary rock layers has been overturned, the bottom rock layer usually
contains fossils
is the youngest
is the oldest
has the finest texture
9
Which is the best explanation for the irregular surface between layers 1 and 2?
Layer 1 was folded after 2 was depos ited.
Pressure from the layers above pushed layer 2 intolayer 1
Volcanic actions pushed layer 1 up before 2 was deposited
Layer 1 was partially eroded before 2 was deposited.
10
which period did surface bedrock separate the Adirondacks from the Catskills formed
Triassic
Jurassic
Ordovician
Precambrian
11
Which rock unit is the youngest?
limestone
shale
sandstone
basalt
12
Which feature is represented by line WX?
an igneous intrus ion
a fault
an area of metamorphism
a former erosional surface
13
Corals are found in warm seas. Coral fossils have been found in the sedimentary rocks of Alaska
Alaska once had a tropical marine environment
Alaska's cold climate fossilized the coral
coral usually develops in cold climates
ocean currents carried the coral to Alaska

Carboniferous Age
Cambrian Age
Tertiary Age
Triassic Age
16
Why is layer 4 likely to be a good time marker?
Volcanic ash is usually a unique gray color
Volcanic ash is usually rapidly deposited over a largearea.
