Question 1
Question
Earth’s lithosphere consists of layers, what are those?
Answer
-
Mantle (Upper)
-
Crust
-
Core
-
Plate
-
Continent
Question 2
Question
It is made of a variety of solid rocks like sedimentary, metamorphic,
and igneous. It has an average density of 2.8 g/cm3
and its thickness ranges
from 5 to 50 km.
Question 3
Question
The crust is the outermost layer of the Earth.
Question 4
Question
What are the two kinds of crust?
Answer
-
Continental Crust
-
Plated Crust
-
Oceanic Crust
-
Icelandic Crust
Question 5
Question
The entire lithosphere of the Earth is broken into numerous segments called plates
Question 6
Question
The plates move very slowly but constantly, and this movement is called tectonics.
Question 7
Question
What are the three types of seismic waves released by an Earthquake?
Answer
-
P-wave
-
D-wave
-
S-wave
-
C-wave
-
L-wave
Question 8
Question
It uses distance information from three seismic stations
to locate the earthquake epicenter.
Answer
-
Triangulation Method
-
Pyramid Method
-
Quantum Method
Question 9
Question
What is the formula to compute for the distance of an earthquake's epicenter from each seismic stations?
Question 10
Question
The places on Earth where most of the earthquakes originated or some mountains and volcanoes were formed mark the boundaries of each lithospheric plate.
Question 11
Question
What are the three distinct types of plate boundaries, which are differentiated by the type of movement they exhibit?
Answer
-
Divergent
-
Convergent
-
Transform Fault
-
Insurgent
Question 12
Question
The denser oceanic crust (Plate A) undergoes what we call subduction process or the bending of the crust towards the mantle.
Question 13
Question
What is the deepest part of the ocean?
Question 14
Question
The subduction of plate can cause earthquakes at varying depths.
Question 15
Question
Converging oceanic plates will cause formation of trenches, and these trenches will become sources of earthquakes.
Question 16
Question
A series of ocean waves with very long wavelengths (typically hundreds of kilometers) caused by large-scale disturbances of the ocean.
Answer
-
Storm
-
Flood
-
Tsunami
-
Earthquake
Question 17
Question
Volcanic island arc is a chain of volcanoes positioned in an arc shape.
Question 18
Question
Many parts of the Philippines originated from oceanic-oceanic convergence. This resulted from the collision of two oceanic plates, with one of the plates diving under the other.
Question 19
Question
When two continental plates converge, a collision zone is formed.
Question 20
Question
What plate boundary is formed when they tend to move apart?
Answer
-
Convergent
-
Insurgent
-
Divergent
-
Oceanic
Question 21
Question
When a spreading center develops within a continent, the crust may break into several segments.
Question 22
Question
A type of plate boundary that resembles the strike-slip fault.
Answer
-
Transform Fault
-
Convergent
-
Insurgent
