Which of the following statements about the Earth’s core is true? A. It is entirely liquid. B. It is entirely solid. C. It is composed of the same material as the mantle. Answer: D. It has a solid inner core and a liquid outer core. Explanation: The Earth’s core consists of a solid inner core and a liquid outer core, both primarily composed of iron and nickel. 2 / 202. Which of the following is a direct source of information about the Earth’s interior? A. Magnetic surveys Answer: B. Gravity anomalies C. Seismic waves D. Volcanic eruptions Explanation: Volcanic eruptions bring magma, or lava, to the surface, providing direct samples of material from the Earth’s interior. 3 / 203. What is the name for the instrument used to record earthquake waves? A. Magnetometer Answer: B. Seismograph C. Mercalli scale D. Richter scale Explanation: A seismograph is a device that detects and records ground motions caused by seismic waves. 4 / 204. Where do mid-ocean ridge volcanoes occur? A. Along the edges of continents B. In the center of ocean basins C. Near subduction zones D. On volcanic islands Answer: Explanation: Mid-ocean ridges are underwater mountain ranges where new oceanic crust is formed through volcanic activity. 5 / 205. Which of the following volcanic landforms is considered the feeder for the Deccan Traps? A. Batholith B. Laccolith C. Sill D. Dyke Answer: Explanation: Dykes are believed to have been the pathways for magma that led to the formation of the Deccan Traps, a massive flood basalt province in India.6 / 206. Which of the following is NOT a factor that affects the reading of gravity at different locations on Earth? A. Temperature Answer: B. Distribution of mass C. Latitude D. Altitude Explanation: While latitude, altitude, and the distribution of mass influence gravity readings, temperature does not have a direct effect. 7 / 207. Which type of earthquake is caused by the collapse of underground mines? A. Tectonic earthquake B. Explosion earthquake Answer: C. Collapse earthquake D. Volcanic earthquake Explanation: Collapse earthquakes are minor tremors caused by the collapse of mine shafts or underground cavities. 8 / 208. What is the name for the outermost solid layer of the Earth? A. Crust B. Core C. Mantle D. Asthenosphere Answer: Explanation: The crust is the Earth’s thinnest and outermost layer, composed of solid rock. 9 / 209. What is the term for the shaking of the Earth caused by the release of energy? A. Seismic wave B. Earthquake C. Fault rupture Answer: D. Tremor Explanation: An earthquake is the shaking or trembling of the Earth’s surface caused by the sudden release of energy in the Earth’s crust. 10 / 2010. What is the name for the point where an earthquake’s energy is released? A. Epicenter B. Focus C. Fault line D. Shadow zone Answer: Explanation: The focus, also known as the hypocenter, is the point of origin of an earthquake within the Earth’s crust. 11 / 2011. What is the term for a wall-like structure formed when lava solidifies within cracks in the Earth’s crust? A. Laccolith B. Sill C. Batholith Answer: D. Dyke Explanation: Dykes are vertical or near-vertical intrusions of igneous rock that cut across existing rock layers. 12 / 2012. Which of the following is NOT a characteristic of flood basalt provinces? A. Explosive eruptions B. Thick basalt layers Answer: C. Highly fluid lava D. Extensive lava flows Explanation: Flood basalt provinces are characterized by massive outpourings of low-viscosity lava, not explosive eruptions. 13 / 2013. Which of the following is NOT a type of volcano classified based on its form and eruption style? A. Composite volcano B. Shield volcano C. Fault volcano Answer: D. Caldera Explanation: There is no recognized type of volcano called a “fault volcano.” 14 / 2014. What is the name for a large, dome-shaped intrusive body with a level base and a pipe-like conduit? A. Batholith B. Phacolith C. Dyke Answer: D. Laccolith Explanation: Laccoliths are lens-shaped intrusions of magma that push up the overlying rock layers. 15 / 2015. What is the name for a volcanic depression formed by the collapse of a volcano? A. Caldera B. Crater C. Vent D. Fissure Answer: Explanation: Calderas are large, basin-shaped depressions that form when a volcano collapses after a major eruption. 16 / 2016. Which of the following is NOT a type of body wave generated during an earthquake? A. None of the above Answer: B. Surface wave C. P-wave D. S-wave Explanation: Surface waves are not body waves; they travel along the Earth’s surface, while body waves travel through the Earth’s interior. 17 / 2017. Which of the following is NOT a characteristic of the Earth’s mantle? A. It is the source of magma. B. It is composed of solid rock. C. It is mostly made up of iron and nickel. Answer: D. It is located beneath the crust. Explanation: The Earth’s core, not the mantle, is primarily composed of iron and nickel. 18 / 2018. What is the term for the difference between the observed gravity value and the expected value at a location? A. Seismic anomaly B. Gravity anomaly C. Magnetic anomaly D. Gravitational shift Answer: Explanation: Gravity anomalies provide insights into the variations in the density and distribution of materials within the Earth’s crust. 19 / 2019. What is the name for the process by which earthquake waves change direction when encountering different materials? A. Diffraction B. Dispersion Answer: C. Refraction D. Reflection Explanation: Refraction occurs when seismic waves bend as they pass through materials with different densities. 20 / 2020. Which of the following is NOT a factor that influences the formation of volcanic landforms? A. Location of lava cooling B. Nature of eruption C. Earth's magnetic field Answer: D. Type of lava Explanation: The Earth’s magnetic field does not play a direct role in the formation of volcanic landforms.
