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. 2 / 202. What is the slowest moving oceanic ridge? A. The Mid-Atlantic Ridge B. The Arctic Ridge C. The East Pacific Rise D. The Indian Ocean Ridge Explanation: The Arctic Ridge has the slowest rate of plate movement compared to other ridges. 3 / 203. What was the name of the sea that separated India from Asia? A. The Atlantic Ocean B. The Pacific Ocean C. The Indian Ocean D. The Tethys Sea Explanation: The Tethys Sea separated the Indian and Eurasian plates before their collision. 4 / 204. What type of plate boundary is the San Andreas Fault? A. Divergent boundary B. Convergent boundary C. Transform boundary D. Subduction zone Explanation: The San Andreas Fault is a transform boundary where plates slide horizontally past each other. 5 / 205. What is the “rim of fire”? A. The area where seafloor spreading occurs B. The zone of active volcanoes around the Pacific Ocean C. The boundary between two continents D. The edge of a tectonic plate Explanation: The “rim of fire” refers to the region around the Pacific Ocean with a high concentration of volcanic activity. 6 / 206. What is the approximate age of the oldest rocks in the oceanic crust? A. 540 million years old B. 4,600 million years old C. 200 million years old D. 3,200 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.7 / 207. What is the asthenosphere? A. A type of tectonic plate B. The mobile layer beneath the lithosphere C. The solid core of the Earth 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. 8 / 208. How many major tectonic plates are there? A. Six B. Seven C. Five D. Eight Explanation: The Earth’s lithosphere is divided into seven major and some minor tectonic plates. 9 / 209. What happens to the oceanic crust at deep trenches? A. It becomes thicker B. It is destroyed C. It is created D. It remains unchanged Explanation: The oceanic crust sinks and is consumed at deep trenches, balancing the creation of new crust at mid-oceanic ridges. 10 / 2010. What is the concept of seafloor spreading? A. Continents are stationary, and only the ocean floor moves B. Movement of continents due to tidal forces C. Formation of mountains due to volcanic activity D. New oceanic crust is formed at mid-oceanic ridges and spreads outwards Explanation: Seafloor spreading proposes that volcanic activity at mid-oceanic ridges creates new crust, pushing the older crust outwards. 11 / 2011. What is the northern plate boundary of the Indian plate? A. The Kirthar Mountains B. The Java Trench C. The Himalayas D. The Mid-Atlantic Ridge Explanation: The Himalayas were formed by the collision of the Indian and Eurasian plates, marking the northern boundary of the Indian plate. 12 / 2012. What is the fastest moving oceanic ridge? A. The Arctic Ridge B. The Indian Ocean Ridge C. The Mid Sources and related content-Atlantic Ridge D. The East Pacific Rise Explanation: The East Pacific Rise has the fastest rate of plate movement, with rates exceeding 15 cm per year. 13 / 2013. What does the term “Pangaea” mean? A. All earth B. Supercontinent C. Land of the dinosaurs D. All water Explanation: The term “Pangaea” translates to “all earth,” referring to the supercontinent that Wegener proposed. 14 / 2014. 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. 15 / 2015. Where was the Indian subcontinent located about 140 million years ago? A. 50°S latitude B. Near the South Pole C. Near the equator D. 50°N latitude Explanation: The Indian subcontinent was located much further south 140 million years ago. 16 / 2016. When did India collide with Asia? A. 40-50 million years ago B. 10 million years ago C. 200 million years ago D. 100 million years ago Explanation: The collision of India and Asia, leading to the formation of the Himalayas, occurred around 40-50 million years ago. 17 / 2017. What major event occurred during India’s movement towards Asia? A. Formation of the Atlantic Ocean B. Separation of Australia from Antarctica C. Formation of the Mariana Trench D. Outpouring of lava and formation of the Deccan Traps Explanation: The Deccan Traps were formed by massive volcanic eruptions during India’s northward movement. 18 / 2018. What is an example of a divergent plate boundary? A. The Himalayas B. The San Andreas Fault C. The Mariana Trench D. The Mid-Atlantic Ridge Explanation: The Mid-Atlantic Ridge is a divergent boundary where the American plates are moving away from the Eurasian and African plates. 19 / 2019. What is the driving force behind plate movement? A. Convectional currents in the mantle B. Magnetic forces C. Tidal forces D. Volcanic activity Explanation: The heat within the mantle creates convectional currents, which are the driving force behind plate movement. 20 / 2020. 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.
