Faults
Which type of fault is being described by the statement: Two tectonic plates moving laterally past each other, causing a horizontal displacement.
A. Normal Fault
B. Reverse Fault
C. Strike-Slip Fault
D. Thrust Fault
C. Strike-Slip Fault
Which type of earthquake wave is responsible for providing information about the Earth's liquid outer core?
Primary Waves or P-waves
What is the name of the region in the Philippines where tropical cyclones are monitored?
Philippine Area of Responsibility
What term describes tropical cyclones that form in the Northwest Pacific Ocean?
Typhoon
Identify the periodic comet visible from Earth approximately every 76 years.
Halley's Comet
Which type of fault is characterized by compression?
Reverse Fault
Can S-waves pass through the Earth's outer core? Yes or No, and why?
No, because S-waves cannot travel through liquid materials.
What specific sea surface temperature is required to sustain typhoon formation?
26°C
True or False -- Precipitation in a typhoon results from warm air rising, cooling, and condensing into water droplets.
True
What do you call the event when Earth passes through the debris left by a comet, resulting in a light display?
Meteor Shower
Morse Type: True or False -- The movement of tectonic plates along faults is the primary source of energy release during earthquakes. Earthquakes only occur along active faults.
First statement is TRUE, second statement is FALSE.
Differentiate the epicenter of an earthquake from its focus.
The epicenter is located on the Earth's surface, directly above the focus, which is the point where the earthquake originates underground.
How do landmasses affect the strength of a typhoon?
They disrupt moisture intake and weaken the typhoon.
Differentiate typhoon, hurricane and a cyclone.
Typhoon: A tropical storm that occurs in the Northwest Pacific Ocean, particularly affecting East and Southeast Asia (e.g., Japan, the Philippines).
Hurricane: A tropical storm that occurs in the North Atlantic Ocean, the Northeast Pacific Ocean, or the South Pacific Ocean, affecting regions like the Americas and the Caribbean.
Cyclone: A tropical storm that occurs in the Southwest Pacific Ocean, the Indian Ocean, or the South Atlantic Ocean, affecting regions like Australia, India, and Africa.
Differentiate meteorites, meteors, and meteoroids.
Meteoroid - A small rocky or metallic body traveling through space.
Meteor - The streak of light produced when a meteoroid enters Earth's atmosphere and burns up due to friction.
Meteorite - A meteoroid that survives its passage through the Earth's atmosphere and lands on the Earth's surface.
What fault type is primarily associated with transform plate boundaries?
Strike-Slip Fault
Which type of earthquake wave is responsible for providing information about the Earth's liquid outer core?
Primary Waves
What is the most significant factor that weakens a typhoon after it makes landfall?
Loss of warm, most air as an energy source
True or False -- The Coriolis effect influences the rotation of typhoons, causing them to spin counterclockwise in the Northern Hemisphere.
True
Morse Type: True or False -- Asteroids have highly elliptical orbits, similar to comets. Comets are primarily found in the asteroid belt between Mars and Jupiter.
Both statements are FALSE.
Creep is the imperceptibly slow, steady, downward movement of slope-forming soil or rock. Movement is caused by shear stress sufficient to produce permanent deformation, but too small to produce shear failure.
True or False -- Earthquake intensity measures the energy released, while magnitude measures the earthquake's effects on people and structures.
False
Morse Type: True or False: The Philippines' location in the Pacific Ocean's warm pool makes it less prone to typhoons. High atmospheric pressure and cold ocean waters are key factors for typhoon development.
Both statements are FALSE.
Discuss how a typhoon is formed.
Typhoons develop over warm ocean waters when the sea surface temperature exceeds 26.5°C. Warm, moist air rises, creating an area of low pressure beneath it. This rising air cools and condenses, releasing heat that further fuels the system.
Explain how meteor showers occur
Meteor showers occur when Earth passes through the trail of debris left behind by a comet. As the debris enters Earth's atmosphere, it burns up, creating streaks of light. The timing of meteor showers can be predicted by tracking the comet’s orbit and noting when Earth intersects the debris field.
