Final answer:
The correct label for the connection between hoodoo formations and frost wedging is 'b. E' for effect, as frost wedging is an erosional process that contributes to the creation of hoodoo formations.
Step-by-step explanation:
In answering the question about the connection between hoodoo formations and frost wedging, the correct labeling would be 'b. E' for effect. Frost wedging, an erosion process, acts over thousands of years as a major contributing factor to the shaping of hoodoo formations which are common in many national parks. This physical process involves the freezing and expansion of water within the cracks and joints of rocks, leading to the gradual breaking apart of those rocks, thus contributing to the creation and perpetuation of the striking hoodoo landscapes.
Frost wedging occurs when water seeps into fractures in the rock, freezes, and then expands. As ice, it exerts significant force on the surrounding rock, eventually causing it to shatter and break apart. This process fits within the larger framework of weathering and erosion that, along with other physical processes like soil creep and chemical weathering, sculpts the earth's surface. Bryce Canyon, in Utah, is a famous example where frost wedging plays a vital role in landscape formation.
