Which of the following is NOT a characteristic of flood basalt provinces? A. Highly fluid lava B. Extensive lava flows C. Thick basalt layers Answer: D. Explosive eruptions Explanation: Flood basalt provinces are characterized by massive outpourings of low-viscosity lava, not explosive eruptions. 2 / 202. What is the term for a wall-like structure formed when lava solidifies within cracks in the Earth’s crust? A. Sill B. Laccolith C. Dyke D. Batholith Answer: Explanation: Dykes are vertical or near-vertical intrusions of igneous rock that cut across existing rock layers. 3 / 203. What is the name for the point where an earthquake’s energy is released? A. Shadow zone Answer: B. Focus C. Fault line D. Epicenter Explanation: The focus, also known as the hypocenter, is the point of origin of an earthquake within the Earth’s crust. 4 / 204. What is the name for a large, dome-shaped intrusive body with a level base and a pipe-like conduit? A. Dyke Answer: B. Phacolith C. Laccolith D. Batholith Explanation: Laccoliths are lens-shaped intrusions of magma that push up the overlying rock layers. 5 / 205. Where do mid-ocean ridge volcanoes occur? A. In the center of ocean basins B. Near subduction zones C. Along the edges of continents D. On volcanic islands Answer: Explanation: Mid-ocean ridges are underwater mountain ranges where new oceanic crust is formed through volcanic activity. 6 / 206. Which of the following is NOT a factor that influences the formation of volcanic landforms? A. Nature of eruption B. Type of lava C. Location of lava cooling D. Earth's magnetic field Answer: Explanation: The Earth’s magnetic field does not play a direct role in the formation of volcanic landforms. 7 / 207. Which of the following statements about the Earth’s core is true? A. It has a solid inner core and a liquid outer core. B. It is entirely liquid. C. It is entirely solid. D. It is composed of the same material as the mantle. Answer: Explanation: The Earth’s core consists of a solid inner core and a liquid outer core, both primarily composed of iron and nickel. 8 / 208. What is the name for a volcanic depression formed by the collapse of a volcano? A. Fissure Answer: B. Caldera C. Vent D. Crater Explanation: Calderas are large, basin-shaped depressions that form when a volcano collapses after a major eruption. 9 / 209. What is the name for the outermost solid layer of the Earth? A. Mantle B. Crust C. Core D. Asthenosphere Answer: Explanation: The crust is the Earth’s thinnest and outermost layer, composed of solid rock. 10 / 2010. Which type of earthquake is caused by the collapse of underground mines? A. Explosion earthquake Answer: B. Tectonic earthquake C. Volcanic earthquake D. Collapse earthquake Explanation: Collapse earthquakes are minor tremors caused by the collapse of mine shafts or underground cavities. 11 / 2011. 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. 12 / 2012. Which of the following is NOT a type of body wave generated during an earthquake? A. None of the above Answer: B. S-wave C. P-wave D. Surface wave Explanation: Surface waves are not body waves; they travel along the Earth’s surface, while body waves travel through the Earth’s interior. 13 / 2013. Which of the following is NOT a type of volcano classified based on its form and eruption style? A. Composite volcano B. Fault volcano Answer: C. Caldera D. Shield volcano Explanation: There is no recognized type of volcano called a “fault volcano.” 14 / 2014. What is the name for the instrument used to record earthquake waves? A. Richter scale B. Seismograph C. Magnetometer Answer: D. Mercalli scale Explanation: A seismograph is a device that detects and records ground motions caused by seismic waves. 15 / 2015. Which of the following is a direct source of information about the Earth’s interior? A. Seismic waves B. Gravity anomalies C. Volcanic eruptions D. Magnetic surveys Answer: Explanation: Volcanic eruptions bring magma, or lava, to the surface, providing direct samples of material from the Earth’s interior. 16 / 2016. What is the term for the shaking of the Earth caused by the release of energy? A. Seismic wave B. Tremor C. Fault rupture Answer: D. Earthquake 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. 17 / 2017. What is the term for the difference between the observed gravity value and the expected value at a location? A. Magnetic anomaly B. Gravitational shift Answer: C. Gravity anomaly D. Seismic anomaly Explanation: Gravity anomalies provide insights into the variations in the density and distribution of materials within the Earth’s crust. 18 / 2018. What is the name for the process by which earthquake waves change direction when encountering different materials? A. Reflection B. Dispersion Answer: C. Diffraction D. Refraction Explanation: Refraction occurs when seismic waves bend as they pass through materials with different densities. 19 / 2019. Which of the following is NOT a factor that affects the reading of gravity at different locations on Earth? A. Altitude B. Temperature Answer: C. Latitude D. Distribution of mass Explanation: While latitude, altitude, and the distribution of mass influence gravity readings, temperature does not have a direct effect. 20 / 2020. Which of the following volcanic landforms is considered the feeder for the Deccan Traps? A. Sill B. Laccolith C. Batholith 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.Please insert your information to see your ranking अपनी Ranking जानने के लिए कृपया अपनी जानकारी भरे NamePhone Number Your score isThe average score is 0% 0% Restart quiz Category: Class 11 Geography Quizzes in English
