Which faults has horizontal movement of rocks along the fault plane?, Inactive fault, Normal fault, Reverse fault, Strike-slip fault, After an earthquake in a Philippine province, a farmer notices that his straight irrigation canal is now disconnected. The left side has shifted 2 meters forward, but neither side is higher than the other. Which type of fault should be mapped here?, A thrust fault, because the canal is located near a mountain range., A normal fault, because the tension in the ground caused a gap to form., A strike-slip fault, because the movement was horizontal along the strike of the fault., reverse fault, because the two sides of the canal were squeezed together until they broke., Based on the understanding of magnitude, why do higher-magnitude earthquakes often result in the collapse of more buildings in a community?, Higher magnitude quakes make the ground turn into liquid instantly, regardless of the soil types., Lower magnitude earthquakes are sharper and break buildings faster than large ones., Magnitude measures how many buildings fell, so a high magnitude means many collapsed., Higher magnitude typically result in longer durations of shaking, which repeatedly stresses until they collapse., A family in your barangay is planning to build a new house. They use the PHIVOLCS FaultFinder and see that a buffer zone of 5 meters is recommended on both sides of a mapped active fault trace. The map shows the fault line is exactly 3 meters from their proposed bedroom. What should they do?, The downward force of gravity on the book is balanced by the upward force from the table., They should build the house with extra windows so they can see the earthquake coming., They should move the house’s footprint further away to ensure it is outside the 5-meter buffer zone., They should ignore the FaultFinder because the lines on the digital map are not real in the physical world., A model shows a deep focus earthquake and a shallow focus earthquake with equal magnitude. Which outcome best applies the concept?, Both produce identical surface shaking., Deep focus causes stronger surface shaking., Shallow focus produces stronger surface shaking than deep focus., Shallow focus causes slightly stronger shaking but explanation unclear., A magnitude 6 earthquake occurs near a town. How should the relationship between magnitude and intensity be correctly applied?, Magnitude measures release energy, while intensity describes shaking that may vary by location., Intensity is usually stronger near the epicenter even if magnitude stays 6., Intensity and magnitude are always equal in value., Intensity depends only on magnitude., A coastal community receives a tsunami warning from authorities after a strong offshore earthquake. Which explanation best describes the procedures used to alert people and keep them safe?, Authorities wait to see if large waves arrive before telling people what to do., Authorities only close beaches while people stay in their homes near the coast., Authorities tell people to watch the ocean first and evacuate only if they see a big wave., Authorities send out warning sirens, emergency alerts, and advise people to move quickly, Which statement best explains why the atmosphere is important to life on Earth?, The atmosphere is important only because airplanes fly through it., The atmosphere is important because it only makes the sky look blue during the day., The atmosphere is important because it holds clouds, but it does not affect living organism., The atmosphere is important because it contains air that living things breathe and helps, When sunlight reaches Earth’s atmosphere, different processes happen. Which statement best explains how energy from the Sun interacts with the atmosphere?, Some of the Sun’s energy is reflected back to space, some is absorbed by the atmosphere and Earth’s surface, and some helps warm the planet., All of the Sun’s energy passes straight through the atmosphere directly to Earth’s surface without any changes., The Sun’s energy only heats the oceans and does not affect the atmosphere., Most of the Sun’s energy stays in space and does not reach Earth., Authorities issue a tsunami alert level warning after detecting a possible tsunami. Which statement best explains why people should follow these warnings?, People should only follow tsunami alerts if the warning lasts for many hours., People should follow tsunami alerts mainly so authorities can test their equipment., People should ignore the alert unless they personally see large waves approaching the shore., People should follow tsunami alert warnings because they provide guidance that helps, Authorities announce different tsunami alert level warnings after a strong offshore earthquake. Which explanation best shows an understanding of what these alert levels mean for communities?, Tsunami alert levels mean a tsunami will always hit every coastal area with the same strength., Tsunami alert levels are used only to inform scientists, and people in coastal areas do not need to take action., Tsunami alert levels tell people that a tsunami might happen, but communities should wait until they see waves before preparing., This option correctly explains that tsunami alert levels communicate the level of risk and, h of the following action is NOT an appropriate procedure recommended by After a strong offshore earthquake, authorities issue a tsunami warning to coastal communities. Which of the following action is NOT an appropriate procedure recommended by authorities during a tsunami warning?, Listening to official alerts and moving quickly to higher ground or designated evacuation centers, Staying informed through emergency messages and helping others evacuate safely., Waiting at the shoreline to confirm if a large wave will arrive before leaving the area., Following evacuation signs and instructions from emergency responders., A powerful earthquake occurs beneath the ocean floor near a coastal area. Which explanation best describes how this earthquake can cause a tsunami that devastates shorelines?, The earthquake shakes the water on the surface, creating large waves that move quickly toward the shore., The earthquake causes strong winds over the ocean, which push water toward the coastline., The earthquake suddenly moves the ocean floor upward or downward, displacing a large volume of water that travels as powerful waves toward land., The earthquake creates cracks in the shore, allowing ocean water to flood coastal, A seismograph recorded the first fast-moving waves that traveled through solids, liquids, and gases. Seconds later, slower waves arrived that could only pass through solids. Which explanation correctly analyzes the types of seismic waves observed?, Both waves were surface waves because they caused shaking., The first waves were P-waves that travel through solids, liquids, and gases, while the second waves were S-waves that travel only through solids., The first waves were surface waves since it can travel to solids then liquids, and the second waves were ocean wave., The first waves were S-waves because they move faster than all other waves., After the shaking stopped, students were told to evacuate. Mark went back to get his phone. Lani calmly lined up and followed the evacuation route. Tom ran without waiting for instructions, and Sarah stayed inside to rest. Who followed the correct procedure after the earthquake?, Mark, because important belongings should not be left behind., Sarah, because staying inside avoids crowding outside., Tom, because running makes evacuation faster, Lani, because she followed the assigned evacuation route calmly.
