What is the asthenosphere? A. The solid core of the Earth B. A type of tectonic plate C. The mobile layer beneath the lithosphere D. The rigid outer layer of the Earth Explanation: The asthenosphere is the partially molten layer beneath the lithosphere, over which the tectonic plates move. 2 / 202. What is the fastest moving oceanic ridge? A. The Arctic Ridge B. The East Pacific Rise C. The Mid Sources and related content-Atlantic Ridge D. The Indian Ocean Ridge Explanation: The East Pacific Rise has the fastest rate of plate movement, with rates exceeding 15 cm per year. 3 / 203. What is the concept of seafloor spreading? A. Formation of mountains due to volcanic activity B. New oceanic crust is formed at mid-oceanic ridges and spreads outwards C. Movement of continents due to tidal forces D. Continents are stationary, and only the ocean floor moves Explanation: Seafloor spreading proposes that volcanic activity at mid-oceanic ridges creates new crust, pushing the older crust outwards. 4 / 204. What is the approximate age of the oldest rocks in the oceanic crust? A. 3,200 million years old B. 200 million years old C. 4,600 million years old D. 540 million years old Explanation: The age of rocks in the oceanic crust does not exceed 200 million years, significantly younger than the oldest continental rocks.5 / 205. What is the slowest moving oceanic ridge? A. The Indian Ocean Ridge B. The Arctic Ridge C. The East Pacific Rise D. The Mid-Atlantic Ridge Explanation: The Arctic Ridge has the slowest rate of plate movement compared to other ridges. 6 / 206. What happens to the oceanic crust at deep trenches? A. It remains unchanged B. It is destroyed C. It is created D. It becomes thicker Explanation: The oceanic crust sinks and is consumed at deep trenches, balancing the creation of new crust at mid-oceanic ridges. 7 / 207. How are the rates of plate movement determined? A. By analyzing magnetic stripes in the ocean floor B. By observing volcanic activity C. By measuring the depth of trenches D. By measuring the height of mountains Explanation: The magnetic stripes in the ocean floor provide a record of plate movement, allowing scientists to determine the rates. 8 / 208. Where was the Indian subcontinent located about 140 million years ago? A. Near the South Pole B. 50°N latitude C. Near the equator D. 50°S latitude Explanation: The Indian subcontinent was located much further south 140 million years ago. 9 / 209. What is the driving force behind plate movement? A. Volcanic activity B. Tidal forces C. Magnetic forces D. Convectional currents in the mantle Explanation: The heat within the mantle creates convectional currents, which are the driving force behind plate movement. 10 / 2010. What major event occurred during India’s movement towards Asia? A. Separation of Australia from Antarctica B. Formation of the Mariana Trench C. Outpouring of lava and formation of the Deccan Traps D. Formation of the Atlantic Ocean Explanation: The Deccan Traps were formed by massive volcanic eruptions during India’s northward movement. 11 / 2011. How many major tectonic plates are there? A. Six B. Eight C. Seven D. Five Explanation: The Earth’s lithosphere is divided into seven major and some minor tectonic plates. 12 / 2012. What is a subduction zone? A. Where mountains are formed B. Where plates slide past each other C. Where new crust is generated D. Where crust is destroyed Explanation: A subduction zone is where one tectonic plate sinks beneath another, leading to the destruction of the crust. 13 / 2013. What is a tectonic plate? A. A large island formed from volcanic activity B. A type of volcano C. A deep trench in the ocean floor D. A massive, irregularly-shaped slab of solid rock Explanation: A tectonic plate, also called a lithospheric plate, is a massive slab of solid rock that makes up the Earth’s lithosphere. 14 / 2014. What type of plate boundary is the San Andreas Fault? A. Divergent boundary B. Transform boundary C. Subduction zone D. Convergent boundary Explanation: The San Andreas Fault is a transform boundary where plates slide horizontally past each other. 15 / 2015. What was the name of the sea that separated India from Asia? A. The Pacific Ocean B. The Atlantic Ocean C. The Tethys Sea D. The Indian Ocean Explanation: The Tethys Sea separated the Indian and Eurasian plates before their collision. 16 / 2016. What is the “rim of fire”? A. The area where seafloor spreading occurs B. The edge of a tectonic plate C. The zone of active volcanoes around the Pacific Ocean D. The boundary between two continents Explanation: The “rim of fire” refers to the region around the Pacific Ocean with a high concentration of volcanic activity. 17 / 2017. What is an example of a divergent plate boundary? A. The San Andreas Fault B. The Mariana Trench C. The Mid-Atlantic Ridge D. The Himalayas Explanation: The Mid-Atlantic Ridge is a divergent boundary where the American plates are moving away from the Eurasian and African plates. 18 / 2018. What does the term “Pangaea” mean? A. All earth B. All water C. Supercontinent D. Land of the dinosaurs Explanation: The term “Pangaea” translates to “all earth,” referring to the supercontinent that Wegener proposed. 19 / 2019. What is the northern plate boundary of the Indian plate? A. The Mid-Atlantic Ridge B. The Himalayas C. The Java Trench D. The Kirthar Mountains Explanation: The Himalayas were formed by the collision of the Indian and Eurasian plates, marking the northern boundary of the Indian plate. 20 / 2020. When did India collide with Asia? A. 10 million years ago B. 200 million years ago C. 100 million years ago D. 40-50 million years ago Explanation: The collision of India and Asia, leading to the formation of the Himalayas, occurred around 40-50 million years ago.
