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