Geological Processes and Plate Tectonics

What supercontinent began to rift approximately 750 million years ago, leading to the formation of the Panthalassa Ocean?

• Pangea

• Gondwana

• Rodinia

• Laurentia

What geological event led to the formation of the Appalachian Mountains?

• The rifting of the North American and Eurasian plates

• The subduction of the Farallon Plate beneath North America

• The collision of the African Plate with Laurentia, forming Pangea

• Upward mantle flow beneath the Colorado Plateau

What process caused magma to rise and crystallize into solid rock, forming features like the granite found in Yosemite National Park and the Sierra Nevada Mountains?

• The rifting of Pangea

• The collision of the African Plate with Laurentia

• The subduction of the Farallon Plate, lowering magma's melting point

• The uplift of the Colorado Plateau

The compression of North America by the subducting Farallon Plate resulted in the formation of which major mountain range?

• Appalachian Mountains

• Sierra Nevada Mountains

• Rocky Mountains

• Cascade Range

What type of plate boundary is the San Andreas Fault, characterized by the North American Plate sliding south and the Pacific Plate shifting north?

• Convergent boundary

• Divergent boundary

• Transform boundary

• Subduction zone
