Which type of volcano is characterized by low-explosivity eruptions and fluid lava flows? A. Composite volcano B. Mid-ocean ridge volcano Answer: C. Caldera D. Shield volcano Explanation: Shield volcanoes have gentle slopes and erupt fluid basalt lava, often in the form of fountains. 2 / 202. Which of the following is an indirect source of information about the Earth’s interior? A. Drilling Answer: B. Meteorites C. Volcanic eruptions D. Mining Explanation: While not from the Earth’s interior, meteorites are believed to be composed of similar material, providing clues about our planet’s composition. 3 / 203. Which of the following is NOT a type of earthquake? A. Collapse earthquake B. Volcanic earthquake C. Magma earthquake Answer: D. Tectonic earthquake Explanation: There is no recognized category of earthquake called a “magma earthquake.” 4 / 204. Which of the following is NOT an intrusive volcanic landform? A. Caldera B. Batholith C. Dyke Answer: D. Laccolith Explanation: A caldera is a large depression formed by the collapse of a volcano after a massive eruption, making it an extrusive landform. 5 / 205. What is the name for a thin, horizontal deposit of intrusive igneous rock? A. Dyke B. Laccolith Answer: C. Sheet D. Sill Explanation: Sheets are relatively thin, horizontal layers of igneous rock formed when magma intrudes between existing rock layers. 6 / 206. What is the term for the release of energy that causes an earthquake? A. Seismic shift B. Tectonic release C. Fault rupture D. Magma flow Answer: Explanation: Earthquakes occur when rocks along a fault suddenly break and slide past each other, releasing energy in the form of seismic waves. 7 / 207. What is the name for the boundary between the Earth’s crust and mantle? A. Asthenosphere Answer: B. Lehmann discontinuity C. Gutenberg discontinuity D. Mohorovicic discontinuity Explanation: The Mohorovicic discontinuity, or Moho, marks the transition between the Earth’s crust and the denser mantle. 8 / 208. Which of the following is NOT a hazard associated with earthquakes? A. Tsunami B. Soil liquefaction Answer: C. Landslide D. Volcanic eruption Explanation: While volcanic eruptions can cause ground shaking, they are not a direct hazard caused by earthquakes themselves. 9 / 209. Which layer of the Earth is the source of magma during volcanic eruptions? A. Asthenosphere B. Inner Core Answer: C. Crust D. Outer Core Explanation: The asthenosphere is a weaker zone in the mantle from which magma rises to the surface during volcanic eruptions. 10 / 2010. Which of the following is NOT a component of volcanic material ejected during an eruption? A. Ash B. Petroleum Answer: C. Pyroclastic debris D. Lava Explanation: Petroleum is a fossil fuel formed from organic matter over millions of years and is not associated with volcanic eruptions. 11 / 2011. Which of the following is NOT a characteristic of composite volcanoes? A. Explosive eruptions B. Pyroclastic material C. Gentle slopes Answer: D. Viscous lava Explanation: Composite volcanoes have steep slopes due to the buildup of layers of lava and pyroclastic material. 12 / 2012. Which type of earthquake wave can only travel through solid materials? A. S-waves B. Surface waves C. All of the above Answer: D. P-waves Explanation: S-waves, or secondary waves, cannot travel through liquids, which is how scientists know the Earth’s outer core is liquid. 13 / 2013. What causes the formation of a shadow zone for S-waves? A. The presence of a liquid outer core B. The Earth's magnetic field C. The Earth's gravitational pull D. The reflection of waves from the Earth's surface Answer: Explanation: S-waves cannot travel through the Earth’s liquid outer core, creating a large shadow zone where they are not detected. 14 / 2014. Which of the following statements about P-waves is true? A. They vibrate parallel to the direction of wave propagation. B. They can only travel through solids. C. They are more destructive than surface waves. Answer: D. They are slower than S-waves. Explanation: P-waves cause compression and expansion in the direction they travel, similar to sound waves. 15 / 2015. What is the name for the zone where earthquake waves are not recorded? A. Volcanic zone Answer: B. Fault zone C. Seismic zone D. Shadow zone Explanation: Shadow zones are areas on the Earth’s surface where certain types of earthquake waves are not detected due to the Earth’s internal structure. 16 / 2016. What is the name for a large body of magmatic material that cools deep within the Earth’s crust? A. Dyke Answer: B. Laccolith C. Batholith D. Phacolith Explanation: Batholiths are massive, dome-shaped bodies of intrusive igneous rock that form deep underground. 17 / 2017. What is the approximate thickness of the Earth’s oceanic crust? A. 200 km Answer: B. 5 km C. 30 km D. 70 km Explanation: Oceanic crust is thinner than continental crust, averaging about 5 kilometers in thickness. 18 / 2018. What is the most destructive type of earthquake wave? A. Body waves Answer: B. S-waves C. Surface waves D. P-waves Explanation: Surface waves travel along the Earth’s surface and cause the most damage during an earthquake. 19 / 2019. What is the name for the scale used to measure the intensity of an earthquake based on its visible damage? A. Magnitude scale Answer: B. Richter scale C. Seismic scale D. Mercalli scale Explanation: The Mercalli scale assesses the impact of an earthquake on the environment and human-made structures. 20 / 2020. What is the point on the Earth’s surface directly above the focus of an earthquake called? A. Epicenter B. Fault line C. Shadow zone Answer: D. Hypocenter Explanation: The epicenter is the point on the surface closest to the focus, where the earthquake’s energy is first felt.
