Upwelling is the intrusion or rising of magma to the surface of the earth. Where does upwelling
process most likely occur?
Abyssal Plain

How does Compressional Stress takes place?
It commonly occurs in transform plate boundaries.
It happens when the dominant force is directed away from each other.
It happens when the two sides are pushed using equal force on the same axis.
It develops when the forces are directed towards each other but not along the same axis.
How does the rocks behave after the application of Compressional Stress?
Be pulled apart
Break apart
Fold or fracture
Lengthen

What happens to the rocks under Shear Stress? The rocks __________.
are pulled apart
are squeezed

walls slip to each other on opposite direction
Pacific Ocean basin is the largest, deepest, and oldest existing ocean basin. Through the formation of
ocean basins, different features and structures are formed, why are undersea mountains flat?
Because of the __________.
earthquake
erosion caused by waves
large marine animals
arge ships that pass through it
How did scientist discover that rocks farther away from the mid-ocean ridge were older than those
near it?
By mapping rocks on the sea floor using sonar
By measuring how fast sea floor spreading occurs
By observing eruptions of molten materials on the sea floor
By determining the age of rock samples obtained by drilling on the sea floor
An ocean basin formed a narrow, irregular seas with young mountains. What stage of the Wilson
cycle was exhibited?
Juvenile
Mature
Suturing
Terminal
Identify which of the following statements is NOT associated with Radiometric dating.
Considering the fossil or organic materials content to identify the estimated eon it belongs.
Examining fossils in one layer with those in a dated layer providing relative timing of events in Earth’s history.
Examining a tree's age by counting the annual growth rings in the trunk of a dicot, with each ring representing one year of growth.
The ratio of parent to daughter atoms in an igneous rock reveals the time since it solidified.
Which statement best explains how flux melting is related to the laws of stratigraphy in geological studies?
Flux melting creates new rock layers on the Earth’s surface, which then follow the law of superposition in stratigraphy, with newest layers forming on top of older ones.
Flux melting alters the position of rock layers, making it impossible to apply the law of original horizontality in stratigraphy.
Flux melting directly supports the law of cross-cutting relationships, as molten rock from the mantle rises and intrudes into pre-existing rock layers.
The process of flux melting directly forms sedimentary layers that can then be used to apply the law of lateral continuity in stratigraphy.
How might decompression melting interfere with the application of the law of superposition in stratigraphy?
Decompression melting causes rock layers to bend, placing older rocks above younger ones.
When decompression melting creates magma, the magma can cut through existing rock layers, disrupting the original sequence and making it difficult to tell the order of the layers.
Decompression melting removes certain layers, making it impossible to use the law of superposition because some parts of the sequence are missing.
Decompression melting leads to erosion of top layers, leaving only the oldest rock layers exposed on the surface, which simplifies the stratigraphic sequence.
What happens during flux melting? Rock’s melting point is _______________.
reduced by adding some water or carbon dioxide
reduced by adding some oxygen or carbon dioxide
increased by adding some water or carbon dioxide
increased by adding some oxygen or carbon dioxide
How can chemical weathering impact the reliability of relative dating in sedimentary rock layers?
Chemical weathering can alter the mineral composition of rock layers, potentially disrupting the sequence used for relative dating.
Relative dating is unaffected by chemical weathering, as it only relies on radioactive decay rates to determine the age of rocks.
Chemical weathering has no effect on the relative dating process because it only occurs on igneous rocks, not sedimentary layers.
The processes involved in chemical weathering help identify the exact numerical age of sedimentary layers though relative dating.
Which of the following is an isotope that is present in the core of the earth?
Uranium – 235
Uranium – 253
Uranium – 523
Uranium – 325
Which of the following best describes Continental Slope?
It is the flattest part of the ocean.
It is where the ocean actually begins.
It starts from oceanic crust to continental crust.
It is part of the ocean basin that extends up from the ocean floor.
What is the difference between a volcanic island and a seamount?
Both the seamount and volcanic island are underwater.
Both the seamount and the volcanic island rise above the water.
A volcanic island rises above the surface of the water and a seamount does not.
A seamount rises above the surface of the water and a volcanic island does not.
