- Q1
How does the composition of the magma affect the formation of the different landforms? The composition of magma determines its ______________.
the land existence of tremendous earthquakes
the existence of phenomenal land features.
viscosity, which affects how a lava flows the kind of volcano formed
the height of the landforms produced.
30s - Q2
What are the resulting forces of metamorphism?
Horizontal pressures are developed as rocks deform and heat is released as rocks bond during crystallization.
The internal heat of the Earth, the weight of overlying rocks, and horizontal pressures developed as rocks become deformed.
Horizontal pressures are developed as rocks deform and heat is released as rocks bond during crystallization.
The weight of the overlying rocks, solar heating, and nuclear fusion.
30s - Q3
While walking on a beach, an Earth Science student with his friend saw a rock which he believes is a “gneiss”. Which characteristic of the rock did he see that would convince his friend?
It demonstrates mode of foliation.
It is a high-grade silicate mineral banded metamorphic rock.
It is commonly used in billiard table construction.
It would fizz with the application of acid.
30s - Q4
What happens when tension acts on rocks?
Compressional stresses cause a rock to shorten.
Longitudinal stress causes the build-up of strain, which causes the deformation of rocks and the Earth's crust.
Tensional stresses cause a rock to elongate, or pull apart.
Shear stresses cause rocks to break down into fine, smaller pieces.
30s - Q5
Rocks respond differently to the same stress because of their ______.
different compositions and physical properties.
different characteristics and origin of formation.
different textures.
formations.
30s - Q6
Seafloor spreading is a process that occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge as illustrated it this Figure. What is the importance of seafloor spreading?
It causes folding of rock layers into mountains that spreads on the Earth’s surface.
Shifts along a fault can also cause earthquakes.
Seafloor spreading helps explain continental drift in the theory of plate tectonics.
The plates are always moving and interacting.
30s - Q7
Which of the following DOES NOT support the theory of seafloor spreading?
Radiometric age dating
Magnetic strips and drilling
Molten material
Presence of plates
30s - Q8
What causes the plates to move?
It is due to human activities.
The heat from radioactive processes within the planet's interior causes the plates to move.
This is due to movements of plants and animals.
This is due to solar and nuclear radiation on the Earth’s surface.
30s - Q9
What type of fault is characterized by the rocks above the fault plane moving downward relative to the rocks below the fault plane?
strike-slip
normal fault
divergent
reverse fault
30s - Q10
Which of the following is the result from either vertical or horizontal stratification of sedimentary rocks?
changes in lava flow
changes in texture or composition during deposition
convection current
formation of internal heat
30s - Q11
Where is the older layer of rock located according to the principle of Superposition?
random
top
middle
bottom
30s - Q12
Which statement best describes the principle of original lateral continuity?
The oldest layer will be on the bottom of the sequence, while all the other layers are successively more recent.
The layers of sediment extend in all directions until they become thinner or until they are interrupted by an obstacle.
Each rock containing inclusions of a neighboring rock must be younger than that rock.
Sedimentary rocks are deposited under the action of gravity, in approximately horizontal layers.
30s - Q13
One way of determining the age of a rock is based on the radioactive decay of isotopes. Which of the following is NOT emitted by the radioactive elements?
protons
α particles
gamma rays
β particles
30s - Q14
Radioactive decay is the emission of energy in the form of ionizing radiation. What happens during radioactive decay?
A stable isotope of one element changes into an unstable isotope of the same element
An unstable isotope of one element changes into a stable isotope of the same element
A stable isotope of one element changes into an unstable isotope of a different element
An unstable isotope of one element changes into a stable isotope of a different element
30s - Q15
The age of a certain rock can be determined by dating. How do scientists perform absolute dating?
The age of rock determined by relative dating.
The age of rock determined by radiometric dating.
The age of rock based on its location.
The age of rock based on living animals.
