You would expect this layer to contain the simplest (least complex) fossils.
Layer 1
100
Explain the relationship between ground and surface water.
Surface water can seep into the ground to become groundwater
100
In what order were these layers of rock deposited over time?
C, B, A, D, E

What type of environment does weathering happen the quickest?
a. hot & dry c. cold & dry
b. hot & humid d. cold & humid
B. hot & humid

Rocks are classified as sedimentary, metamorphic, or igneous on the basis of ___________
The way the rocks are formed
200
Paleontologist know that the dashed rock layer is the same age at both Outcrop 1 & 2 because of this.
They have the same fossils present at both layers
200
What part of the water cycle would you have erosion taking place?
Run off
200
They have the same type of fossils
200
This process moves rock particles by wind, water, and ice.
What is erosion?
200
True or False
Any rock can change and become any other type of rock
True
300
These two fossils would make good index fossils.
Trilobites & Ammonites
300
When water infiltrates the ground, the water tends to move downward until it reaches what?
Water Table
300
What type of rock feature is layer D?
Intrusion
300
This sandstone erosional feature was formed near the Grand Canyon. What erosional agent is most likely sandblasting this rock formation?

a. waves
b. ice
c. wind
c. wind
300
This type of rock is formed due to cooling and crystallization.
Igneous Rock
400
A student stated: Marine animals with hard body parts are less likely to fossilize than marine animals with soft tissues.
Is the student correct?
No. Marine fossils with soft tissues are less likely to fossilize.
400
Which diagram represents the soil with the greatest permeability?
Diagram 4
400
Scientist discovered a crater near the Yucatan peninsula. This crater is believed by scientist to have formed due to the impact of a giant asteroid that struck earth more than 65 million years ago. During this time a large amount of debris was released into the atmosphere and blocked the sun. How could this catastrophic event have affected the Earth's environment at that time?
It caused a mass extinction of most life forms at that time due to climate change. The debris blocked the sunlight (insolation) which lowered temperatures worldwide.
400
This diagram shows a natural process that weathers rock. What type of weathering would this be?
Mechanical (Physical) Weathering
400
What is the stage where fossils are formed?
When sediments turn into sedimentary rock
500
This information can be learned from a fossil using the Law of Superposition.
The age of the fossil comparing it to other fossils
500
Letters A through F represent some processes of the water cycle. Letter X indicates the top of the underground zone that is saturated with water.
Which process is represented by letter F?
Infiltration
500
240 million years old
500
What's the difference between the processes that formed these two caves?
The underground cave has been formed due to chemical weathering while the sea cave was formed due to the weathering of the rocks by waves.
500
Correctly list the steps of an INDIRECT way igneous rock can become metamorphic rock?
Igneous rock goes through weathering and erosion to become sedimentary rock. Then sedimentary rock goes through intense heat and/or pressure to become metamorphic rock.
