Washingtion history: How was the Olympic Peninsula formed? (1 point) Responses by subduction, which resulted in an excessive amount of volcanic activity by subduction, which resulted in an excessive amount of volcanic activity through volcanic activity off the coast of Washington that led to the buildup of Pacific plates through volcanic activity off the coast of Washington that led to the buildup of Pacific plates when a large chunk of the ocean floor was lifted up and attached to Washington’s coastline when a large chunk of the ocean floor was lifted up and attached to Washington’s coastline when shifting plates caused a large section of land to break away from Washington’s coast when shifting plates caused a large section of land to break away from Washington’s coast

The Olympic Peninsula was primarily formed through the process of subduction. This geological activity involved the Juan de Fuca Plate being forced beneath the North American Plate, which resulted in significant volcanic activity and the uplift of land. The combination of volcanic activity and tectonic processes over time contributed to the unique landscape of the Olympic Peninsula. Therefore, the correct response is: "by subduction, which resulted in an excessive amount of volcanic activity."
