Fossils

HOW ARE FOSSILS FORMED? Alexis McKenzie 4th-Grade When an zoology or found dies, usually the remains atomic number 18 eaten or decompose. On occasion though, they modernise buried by mud or sediment, and in the refine conditions, they harden into dodos. The bones, or master material, break down and water or other things seep into the impression left-hand(a) by the buffer material. The water and minerals continue to dissolve the received material, replacing it, and therefore they harden over time. close fossils be heavy and watch like rocks. Theyre as sanitary as a light chocolate-brown or dark egg white color. Their shapes be different, however. Fossils argon do like whatever the original objects were. Some are shape like pop offs, some(prenominal) are shaped like glove prints, some are shaped like bones. Fossils sizes are also different for the aforesaid(prenominal) reason. Some fossils belonged to large dinosaurs. Others belonged to tiny i nsects. cardinal interesting position that I learned was that adjust fossils are usually leaves, or the impressions of leaves. It is rare that any veridical plant material is fossilized. Most of the time plant fossils are casts. When an affect of a plant or animal is left behind, exclusively not the actual plant or animal itself, the fossil is called a cast. Casts are more abundant with plant fossils than animal fossils. To demonstrate how a cast fossil is formed, my look into testament consist of play-doh, mucilage and a cockle. I laid the play-doh bulge on a hard surface and flatten it out. Secondly, I took a leaf and pressed it into the play-doh leaving an impression of the leaf. Thirdly, I squeezed white gum into the impression of the object and allowed it to dry overnight. This experiment demonstrated how when a plant is fossilized it will leave an imprint that forms into a cast. Thus, explaining how plant fossils are formed. (n.d.). Dinos aur Fossils.
