1.they have varying resources, industries, and populations.
Step-by-step explanation:
Regions of Washington contribute to the economy in different ways because "they have varying resources, industries, and populations."
This is evident in the fact that the regions of Washington are in five places namely: Coastal Range, the Puget Sound Lowlands, the Cascade Range, the Columbia Plateau, and the Rocky Mountain region.
Each of the regions has its varying resources, industries, and populations that make them unique in the economic contributions.
For example, the coastal region has fishing and timber industries. Puget Sound Lowlands has a higher population and aerospace and software industries.
Cascade Range is well known for having volcanic mountains. Columbia plateau has a large territory and is well known for farming wheat, apples, cherries, and grapes.
Also, Rocky Mountain is well known for ranching, farming, and mining.
