EOSC 110 MIDTERM ONE ACTUAL 2025/2026 QUESTIONS AND 100% CORRECT ANSWERS What is the Core made of? - Answer -Predominantly iron and nickel Is the inner core solid or liquid? - Answer -Solid What are the properties of the Mantel? - Answer -It is less dense than the core, has an abundance of iron and magnesium, and lots of silicates What are the properties of the Crust? - Answer -It is the least dense, has an abundance of silicates, and is richer in potassium and sodium. What are tectonic plates made of? - Answer -Broken lithosphere chunks that are strong, cool, brittle, and form an outer shell. These plates float on top of the asthenosphere. What is an active margin? - Answer -Regions where lithospheric plates interact with each other. What is a passive margin? - Answer -Transitions between oceanic and continental crust where there is no interaction between plates.

Do Transform Boundaries have volcanoes and earthquakes? - Answer -They have earthquakes but not volcanoes. What is Magnetic Striping? - Answer -Changes in polarity are recorded in rock that crystallize from magma. This polarity recorded on the sea floor can be correlated to dated rocks on land. What are ways to track plate movement? - Answer -GPS tracking, Hot Spot tracking, lithological correlation. How fast do tectonic plates move? - Answer -About the same velocity as human finger nails grow. What is a ridge push? - Answer -Movement of plates at ridges is propelled by sliding along the elevated lithosphere-asthenosphere boundary. What is a slab pull? - Answer -Dense sub-ducting lithosphere "pulls" the plate away with it. What is the definition of a mineral? - Answer -1. Inorganic 2. Naturally occurring 3. Crystalline Solid 4.
