Question

when a heavier sea plate dives beneath a lighter continental plate, this process is known as ____. a) faults b) tectonics c) accretion d) subduction when moving plates grind past each other, the activity sometimes produces cracks called ____. a) faults b) folds c) accretions d) volcanoes

Explanation:

First Question:

• Option A: Faults are fractures in Earth's crust where movement occurs, not the process of one plate diving under another.
• Option B: Tectonics is the study of plate movements and related processes, not the specific process described.
• Option C: Accretion is the growth of a landmass by adding material, not subduction.
• Option D: Subduction is defined as a denser (heavier) oceanic plate diving beneath a less dense (lighter) continental plate.

• Option A: Faults are cracks (fractures) in the Earth's crust formed when plates grind past each other (transform boundary movement).
• Option B: Folds are bends in rock layers due to compressional forces, not from plates grinding past.
• Option C: Accretions are related to adding material to a landmass, not cracks from plate movement.
• Option D: Volcanoes are formed by magma rising, not from plates grinding past to form cracks.

Answer:

D) subduction
