What is the first step a scientist takes in the scientific method?
what is Making Observations
Lists the layers of the
Earth that are defined by chemical
composition?
What are the three types of plate
boundaries?
what is convergent (subduction zone), divergent (mid-ocean ridges), Transform Boundaries.
True or False: An erosional event is
considered an unconformity.
what is true
what are the three types of sedimentary rocks?
what is Clastic, Bioclastic, and chemical
True or False: Earth systems are simple feedback loops. Processes don't interact and affect one another.
What is False
True or False: P-waves and S-waves are the
waves from an earthquake that cause the
most damage to buildings.
what is False
True or False: Subduction zones are areas
where crust eventually gets destroyed,
balancing out the new crust created at mid-
ocean ridges.
what is True
Strike-slip faults are most typical of what type of plate boundary?
what is Transform
Which type of unconformity is defined as
when there is sedimentary rock on top of a
different rock type (such as seen in the
Grand Canyon)?
what is disconformity
How do geologists think about time?
what is in millions of years or very long periods of time
Which of the following is untrue regarding rock formation?
a) Most rocks form at the Earth's surface
b) Most rocks form underground and are exposed when overlying rocks are removed.
c) Most rocks form underground and are pushed to the surface by magma.
what is a.)Most rocks form at Earth's surface
Which of the following responses best summarizes the relationship between volcanoes, large earthquakes, and tectonic plates?
a.) Volcanoes can happen anywhere; earthquakes happen only on the edges of plates
b.)Earthquakes can happen anywhere; volcanoes only happen on the edges of plates.
c.)Volcanoes and earthquakes can happen anywhere, but most of them are at plate boundaries.
d.)Volcanoes and earthquakes are distributed fairly equally across the map.
what is c.)Volcanoes and earthquakes can happen anywhere, but most of them are at plate boundaries.
Thrust faults are most typical of what type of plate boundary?
what is convergent
What type of sedimentary structure is showing in this sandstone?
what is cross bedding
What defines the boundaries in the geologic time scale, such as eons and periods?
what is the Fossil Record
How is the velocity of sound (and seismic waves) affected by the density of the material it is passing through (air, water, rock, etc.)?
What is The higher the density, the faster the waves move
what evidence supported Hess’
seafloor spreading hypothesis?
what is The ocean floor is younger in the
middle and older on the edges
What factors influence the size of an earthquake? (multiple answers)
a. Strength of the surrounding rocks
b. Rate of plate motions
c. Friction on the fault
d. Strength of the fault
what is A, B, and C
Which is NOT a correct characterization of an isotope?
a. Atoms with the same number of protons, different numbers of neutrons.
b. Atoms of the same element, but with different numbers of protons.
c. Atoms with the same atomic number, different atomic weights.
d. Atoms of the same element but with different atomic weights.
what is B.Atoms of the same element, but with different numbers of protons.
The rock on top of Mt. Everest is a shallow marine limestone deposited 200 million years ago. What does this tell us about the geologic history of the Himalayas?
a) 200 million years ago the Himalayas did not exist.
b) The ocean level 200 million years was much higher than today.
c) There was a high altitude lake in the Himalayas.
What is a) 200 million years ago the Himalayas didn't Exist.
True or False:
1) The difference between crust and mantle is based on chemical composition
2) The difference between the lithosphere and asthenosphere is based on convection.
What is 1. true 2. false
What testable prediction could Fred Vine make about the mysterious magnetic striping on the ocean floor if Hess' idea of new crust forming at the mid-ocean ridges is correct?
a.)The magnetic reversals must be a an artifact of the measuring tool, not a real phenomenon.
b.)The magnetic reversals will be randomly arranged.
c.)The magnetic reversals will be symmetrical parallel to the ridge.
d.)The magnetic reversals will be very old
What is c.) The magnetic reversals will be symmetrical parallel to the ridge.
If you are walking across a flat plateau, and cross these rock units (below), how do know you are crossing a fold
what is the rock units repeat
Which geologic principle tells you the age relationship between metamorphic rock C and sandstone F?
what is the principle of superposition
