Geology Exam 2 Questions Correctly Answered. What do the two stars near the center of this block represent? - CORRECT ANSWER a) location of the earthquake b) the star at depth is the place where the earthquake is generated c) the star at depth is the hypocenter d) the star on the surface is the epicenter e) All of the Above All of the Above is the answer An earthquake generated on this type of fault would most likely be associated with a: - CORRECT ANSWER transform boundary If ...

What is convection correct answers Cold air sinks because it is more dense What is the lithosphere correct answers The top part of the mantle and all crust, on top of asthenosphere In SoCal our plate boundary is... (list plate, boundary and rise) correct answers Pacific plate, transform boundary, east pacific rise Why is San Francisco in the same location correct answers It must be East of the San Andreas What will happen to Western California correct answers It will move more northw...

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...

Volcanic eruptions C. Meteorite impacts D. Radiation decay - C. Meteorite impacts How does metasomatism affect lithospheric diamond formation? A. Supplies heat B. Transports rock C. Removes oxygen D. Provides hydrogen - C. Removes oxygen What are the rock types where most diamonds form? A. Basaltic cr...

Which of the following best describes the fundamental concept if superposition? - Any sedimentary deposit accumulates on older rock or sediment layers. New oceanic crust and lithosphere are formed at ______________ - divergent boundaries by submarine eruptions and intrusions of mafic magma Deep ocean trenches are surficial evidence for _________________ - Sinking of oceanic lithosphere into the mantle at a subduction zone. Since the early Mesozoic, the ________ has been passive tectonica...

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...

superposition - The principle that any given rock layer is probably older than those above it and younger than those below it continental crust - Extends from surface of Earth down to 20-30 miles. Continental crust (granite) is less dense then ocean crust (basalt). oceanic crust - Extends down from the surface of the Earth to 7 miles. Crust is layered and very uniform. Composed of basalt. mantle - Contains most of Earth's mass. Composed of iron, magnesium, aluminum, and siliconoxygen comp...

The type of magma associated with oceanic hot spots - mafic Decompression melting in this setting forms a long, submarine ridge - divergent boundary When mafic magma rising from the mantel rises through this type of crust, it will form int-felsic magma - Continental crust Shield volcanoes may form here, when magma upwells from the asthenosphere - hot spot The type of magma that most commonly forms at subduction zones - int-felsic magma This tectonic setting can form an explosive caldera - ...
