Question 25 (1 point)
Certain types of lichen grow on rocks. These lichen secrete a form of acid that breaks bonds and weakens the rock over time. This is an example of:
a
Salt Wedging
b
Abrasion
c
Chemical Weathering
d
Physical Weathering
Question 26 (1 point)
At a convergent boundary, where a more dense plate sinks underneath the less dense plate, the process ____ occurs.
a
subduction
b
mountain building
c
divergence
d
metamorphism
Question 27 (1 point)
The resulting landforms of two Oceanic plates converging is a Deep Ocean Trench along an Island Arc.
True
False; non-volcanic mountains
Question 28 (1 point)
Earth Scientists found a Fossil in a Sedimentary rock formation. How can they use Radiocarbon dating of the Fossil to determine the ages of the rock layers around it?
a
Radiocarbon dating is Absolute dating which will determine the exact age of the fossil, and therefore also its rock layer. Once they know the age of this layer, they can estimate the ages of the adjacent rock layers above and below it through relative aging.
b
Radiocarbon dating determine the amount of carbon still present in the fossil/rock layer and then you can use the equation of carbonation from chemical weathering to determine the age of the layers above and below it.
c
Radiocarbon dating is only a Relative dating procedure, and therefore they would not be able to tell any specific ages of the fossil, the rock layer it is embedded in, or the rock layers above or below it.
