Answer:
1.)The tilting of rocks or folding or uplifting of the rock.
2.)deposition of new sediments
Explanation:
ANGULAR UNCONFORMITY usually take place when strata of sedimentary rock are deposited and tilted on another layer where the upper layer is younger compare to lower layer. The unconformity could represent the period of time where there no preserved sediments in s region.
TITLING of rocks can occur in many dimension, such as pushing upward of the rock or folding of sedimentary rock,
and this is the first geological
event that needs to take place for angular unconformity to occur.
DEPOSITION OF NEW SEDIMENTS, this is when the layers formed during the tilting of the sediments later turn to rock, and the layer of the sedimentary rocks are compressed and there would be occurrence of angles in the rock. This is the final event in which angular unconformity take place.
