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