What land form can be produced by the collision of two continental plates?
a.oceanic ridge
b.oceanic trench
c. mountain ranges
d.mountain volcanoes
Plate boundaries are the cracks or the gaps found in between crustal plates.These boundaries are classified based on how two plates move with one another.If two tectonic plates move away from each other what kind of plate boundary do they have?
a.convergent boundary
b. divergent boundary
c.seismic boundary
d. transform boundary
Which of the following will form if two oceanic plates collide in their boundary?
a.oceanic ridge
b. oceanic trench
c. mountain ranges
d. volcanoes
These are areas of the Earth where plumes of magma rise from the outer core and seeps through the crust resulting to volcanic eruption. What do you call these areas?
a. crustal plates
b.hot spots
c.plate boundaries
d.tectonic plates
What converging tectonic plates has no formation of trench, volcano instead just a large group of tall mountains?
a. continental plate & continental plate
b. continental plate & oceanic plate
c.oceanic plate & oceanic plate
d. none of the above
What geologic structures or features are formed in the diverging of tectonic plates
a. formation of rift valleys & oceanic ridges
b.. mountain ranges
c. Volcano
d. volcanic arc
What do you call the deepest part of the ocean? These are also called sub marine valleys formed from the collision of continental and oceanic plates?
a.ocean trenches
b.volcanic island
c. volcanic arc
d.mountain ranges
The San Andreas Fault in California is formed by two large plates moving side to side at opposite direction. What plates formed the San Andreas fault?
a. Eurasian Plate & Pacific Plate
b.Eurasian Plate & North America Plate
c.North American Plate & Pacific Plate
d.Indo Australian Plate & South American Plate
Fault lines are large cracks on the Earth's crust. These are formed when two tectonic plates rub ( moved side by side) against each other. What plate boundary formed these fault lines?
a. convergent boundary
b. divergent boundary
c. transform boundary
d. seismic boundary
Which among the continents will unlikely to experience volcanic eruptions?
Australia
South America
East and Southeast Asia
Western Coast of North America
Where do most of the active volcanoes located?
Mid-continents
Eastern coastline of the Continents
Equatorial Ocean Floor
Edges of the Tectonic Plates
Divergent Plate boundaries forms from the pulling away of plates from each other. When this process happens on land, where is the volcano form?
Rift Valley
Hotspot
Mid -Ocean Ridge
Parallel to the trench
How are most of the earthquake distributed?
not randomly
scattered
randomly
concentrated on the middle of the continents
What two important positions are necessary when pin pointing the location of an earthquake on a map?
Left and Right
East and West
Latitude and Longitude
North and South
The data from seismogram show the arrival time of the P and S waves, which of these can you possibly determine?
The damage at the focus.
The distance to the earthquake.
The intensity of the earthquake.
The location of the epicenter.
Which of the following can be used to determine the distance from the epicenter?
The arrival of surface waves.
The speed of the surface waves.
The difference in the arrival time of the P and S waves.
The ratio of the amplitude of the largest P and S waves,
During the 1960s scientist were already equipped with gadgets needed to explore the deep ocean. What discovery about the ocean floor is associated with the seafloor spreading?
Mountains are denser than the mantle.
The rotational poles of the Earth have migrated.
The crust of the continents is more dense than the crust of the ocean.
The crust of the ocean is very young relative to the age of the crust of the continents.
Who were the two scientists who proposed seafloor spreading in the early 1960s?
Charles Darwin and James Hutton
Harry Hess and Robert Dietz
John Butler and Arthur Smite
Alfred Wegener and Harry Hess
How is the concept of seafloor spreading being stated?
Seafloor is created at the mid-ocean ridges and destroyed at deep ocean trenches.
Sea level is rising.
The earth is expanding.
Earthquakes occur underwater.
If all of the inner layers of the earth are firm and solid, what could have happened to Pangaea?
It remained a supercontinent.
It would have become as it is today.
It would have slowly disappeared in the ocean.
It would have stretched and covered the entire world.
Which of the following theories was proposed by Alfred Wegener?
Continental Drift Theory
Theory of Evolution
Seafloor Spreading
Magnetic Reversals
The lithospheric plates are believed to be moving slowly. What is the driving force that facilitates this movement?
Gravitational force of the moon.
Magnetic force at the poles.
Convection current in the mantle.
The force of the atmosphere.
The movement of the lithospheric plates is facilitated by a soft, weak and plastic-like layer. Which of the following layer is described in the statement?
Asthenosphere
Athmosphere
Lithosphere
Mantle
Which of the following can you infer from the continuous movement of the lithospheric plates over the asthenosphere?
All of the continents
All the volcanoes in the Philippines will become inactive
The continents will not be located in the same place as they are now.
The island of the Philippines will become scattered all over the world.
It occurs at the mid ocean ridges as the result of the rigid lithosphere sliding down the hot raised asthenosphere below the ocean ridges. It is also called gravitational sliding
Convection Current
Slab Pull
Ridge Push
