Answer» According to the passage, When an animal or plant DIES, it may fall into mud or soft sand and make an impression or mark in the DIRT. The body is then covered by another layer of mud or sand. Over time, the body falls apart and is dissolved. The mud or sand can harden into ROCK preserving the impression of the body, leaving an animal or plant shaped hole in the rock. This hole is called a MOLD fossil. If the mold becomes filled over time with other MINERALS the rock is called a cast fossil. So option 3 is the right answer. |
