sedimentary rocks that record deposition of fine grained sediments following by subaerial desiccation would likely contain which of the following sedimentary structures?
convoluted bedding
cross bedding
ripple marks
mudcracks

Explanation:

• For Question 15: VEI stands for Volcanic Explosivity Index, a scale for measuring the explosiveness of volcanic eruptions.
• For Question 16: Mudcracks form when fine - grained sediments dry out and crack due to subaerial desiccation.
