9 Questions
Match the branches of Geology with their descriptions:
Mineralogy = Study of properties & uses of minerals Petrology = Study of types of rocks Structural Geology = Study of causes and classification of geological structures Historical (Stratigraphy) = Study to understand the origin of Earth
Match the following layers of the Earth with their descriptions:
Crust = Rocky silicate material with some aluminum & trace amounts of all naturally occurring elements Mantle = Largest chemical layer by volume, composed of silicates with large amounts of iron & magnesium Core = Consists mostly of iron, nickel, and possibly some oxygen, magnetic iron & nickel responsible for Earth's magnetic field Continental Crust = Relatively low density, composition similar to granite
Match the Geotechnical Issues with their descriptions:
Road Subsidence = Occurrence of shrinkage in subsoil Road Damage = Result of road construction on slope without proper protection Bridge Wash Out = Protection required for soil below the bridge Liquefaction = Result of supersaturation of water/soil leading to landslide
Match the Engineering Responses with the corresponding challenges:
Soft Ground & Settlement = Redistribute loading to address the issue Weak Ground & Potential Failure = Ground improvement/cavity filling as a solution Unstable Slopes & Potential Sliding = Stabilize/support slopes to prevent sliding Severe River/Coastal Erosion = Use concrete defenses to combat erosion
Match the following types of crust with their characteristics:
Oceanic Crust = Relatively high density, composition similar to basalt Continental Crust = Thickness of 30-70 km, relatively low density, composition similar to granite
Match the following discontinuities with their descriptions:
Mohorovicic Discontinuity = Zone between Earth’s solid crust & mantle where density shifts dramatically Gutenberg Discontinuity = Base of the mantle, at the boundary with the outer core, where P waves slowdown and S waves vanish completely
Match the following Earth layers with their characteristics:
Lithosphere = Includes brittle upper portion of the mantle & the crust, outermost & coolest layer Asthenosphere = Moves & flows due to convection currents, relatively unbroken
Match the following historical figures with their contributions to Earth science:
Alfred Wegener = Identified lines of evidence supporting continental drift theory, proposed Pangaea Marie Tharp & Bruce Heezen = Started using SONAR in 1947 to map middle of Atlantic Ocean
Match the following factors for creating distinct chemical layers with their role:
Temperature = One of the factors essential for creating 3 distinct chemical layers Pressure = One of the factors essential for creating 3 distinct chemical layers
Test your knowledge on the core branches of geology like physical, historical, mineralogy, petrology, and structural geology. Learn about the science of geology, understanding the processes that shape the Earth's surface, the types of rocks and minerals, and geological structures.
