How a rock formed from explosive volcanic eruption could resemble a clastic sedimentary rock?

A rock formed from an explosive volcanic eruption, such as volcanic ash or pumice, can resemble a clastic sedimentary rock due to its fragmented texture and composition. During an eruption, volcanic materials are expelled and can rapidly cool and fragment, creating particles that can be similar in size and shape to sedimentary clasts. If these volcanic fragments become compacted and cemented over time, they may resemble clastic sedimentary rocks, which are typically formed from the accumulation and lithification of pre-existing rock fragments. Thus, both types of rocks can share similar physical characteristics despite their different origins.
