Subduction Guides d'étude, Notes de cours & Résumés

apes unit 4 frq with 100% correct solutions 2024/2025describe what happens when two tectonic plates collide in a subduction zone - correct answer in a subduction zone, one plate is pushed beneath the other. a trench may be formed at the subduction zone. explain how subduction leads to volcanic activity - correct answer The plate closer to the core melts and becomes magma, which pushes towards the surface. When the magma reaches the surface, it becomes lava and releases through the crust cau...

What is Geology "Earth knowledge" -Scientific study of our planet -Earth's history -Earth's composition -Earth's internal structure -Earth's surface features Sustainable Development Earth is a "spaceship" with limited resources and a delicate life-support system. "Sustainable Development": Current generation must ensure hospitable planet for future generations. The Roles of Geologists -Find and manage NATURAL RESOURCES -Understand Earth processes well enough to ...

APES Unit 4 Vocab fully solved 2024 passedCore - correct answer The innermost zone of Earth's interior, composed mostly of iron and nickel. It includes a liquid outer layer and a solid inner layer. Mantle - correct answer The layer of Earth above the core, containing magma. Magma - correct answer Molten rock. Asthenosphere - correct answer The layer of Earth located in the outer part of the mantle, composed of semi-molten rock. Lithosphere - correct answer The outermost layer o...

Convection in the Earth's mantle is related to? - ️️-Spreading at MORs. -Convergence at subduction zones. -Rifting of Continental crust. Based on this image what is going on near the grey where the rock is colder? - ️️The rock is denser and sinks What process is being represented by this figure and what is happening to the continental crust ? - ️️-Rifting and upwelling in the mantle below this region which is causing the plate to extend -Rifting, driven in part by subductio...

Aa flow - A type of lava flow that has a jagged, blocky surface. Ablation - A general term for the loss of ice and snow from a glacier. Abrasion - The grinding and scraping of a rock surface by the friction and impact of rock particles carried by water, wind, and ice Abyssal plain - A very level area of the deep-ocean floor, usually lying at the foot of the continental rise. Accretionary wedge - A large wedge-shaped mass of sediment that accumulates in subduction zones. Sediment is scr...

Theory of Plate Tectonics - ANSWER A theory stating that Earth's lithosphere is broken into huge plates that move and change in size over time - explains the process of continental drift - theory is a fusion on the theories of continental drift and seafloor spreading - continents are not floating on the ocean, rather they are rooted What are the 10 major plates of the Earth's lithosphere? - ANSWER African, Antarctic, Australian, Eurasian, North American, South American, Pacific, Cocos, N...

Employee Assistance Programs | EAPS 100 Exam 1 The point where oceanic crust begins sinking in subduction zones is marked by what type of topographic feature? A deep canyon known as a 'trench' What is the key process that causes the ocean crust to be pulled into the Earth's mantle? Metamorphism transforms the basalt that forms ocean crust into a rock that is more dense than the Earth's upper mantle. This transition pulls oceanic crust downward as it sinks. We now think that plate tectonics...

A rock described as arkosic - correct answer is sandstone containing > 25% feldspar If the scale of a map is 1:24000 what does 1 in on a map represent - correct answer 2,000 ft In a region eroded by glaciers, what are bow shaped depressions at the head of a glacial valley? - correct answer Cirques Which two-letter symbol is commonly used for a fat clay? - correct answer CH For a dip-slip fault, what is the area above the fault plane known as? - correct answer Hanging wal...
