Hey there! I'm happy to help!
This type of rock is called breccia. You may have seen it before. It looks like a ton of random rocks squished together. These types of rocks are sedimentary because they are made up of fragments of other rocks that were basically sealed together, so they are technically made of sediments. The word <u>clastic</u> means the rock is made up of pieces of preexisting rock.
Have a wonderful day and keep on learning! :D
Earthquakes produce three types of seismic waves: primary waves, secondary waves, and surface waves. Each type moves through materials differently. In addition, the waves can reflect, or bounce, off boundaries between different layers.
