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