Question 2 1/1pts Danny Macaskill puts poetry into mountain biking in " The Ridge & ". Enjoy the whole video, but this question relates to the section of the video starting at 2:35 and ending at 2:50. This section was clearly shot in the high alpine where there is lots of snowfall, snow melt, and then refreezing. The question: what is the process that splits the bedrock into the large blocks that Danny was riding over? freezing of water in tiny fractures exerts a hydraulic pressure that opens the fracture further even though its very cold, dissolution of the rock in joint fractures generated the bedrock splitting oxidation of the iron minerals exerts enough pressure to split the bedrock into the large boulders chelation of organic acids exerts pressure on the walls of fissures, pushing them apart
