Which word means the history of life in the geologic past as indicated by the imprints or remains of living things?
Fossils are created by the mineralization of the remains of dead organisms, especially their skeletons. Sometimes there are fossil imprints where remains were pressed into rock, ash, or sediment that later hardened. More rarely, an animal part decomposes and the space is filled to form a cast impression. (see the related link)
All fossils are non-living. However, they are always created by living things. Fossils are either a form of preserved remains of a living thing from at least hundreds of thousands of years ago (otherwise they are simply remains), or they are the remnants of signs of a living thing from an equally long period ago (footprints, imprints, fossilized dung, etc).
only if a turtle counts to 5 Real answer, no they aren't. Shells are made of minerals such as calcium, which molluscs derive from thei environment. The only shells that could be classed as rock aren't really shells at all but fossilised remains of them- fossils being the imprints left behind in sedimentary rocks by prehistoric animals and plants after their real remains have rotted away.
I think your looking for Fossils, They contain imprints of Plant and Animal material up to millions of years old. If you want a specific rock that contains Preserved animal or plant remains, try Amber, its Tree sap that has solidified into rock over time and often the insects or plants are perfectly preserved inside. I hope this was helpfull!
Fossils are the preserved remains or traces of organisms that lived in the geologic past. Trace fossils are made by marks left by organisms while still alive, such as tracks, burrows, and dung. Decomposition, weathering, and scavenging all contribute to what makes fossils so rare. Almost all fossils are found in sedimentary rock; almost none are found in metamorphic or igneous rock. Fossils are our only direct key to the past, informing us about migratory…
Earth does have impact craters, but it has much few than the moon or Mercury and many of them are not readily visible. The main reason is that Earth has many active geologic processes that renew and change its surface, burying and destroying impact craters. If an impact crater on Earth is clearly visible then it probably formed quite recently in geologic history. Many of the impact craters on the moon and Mercury are billions…
I guess it depends on your ISP. I'm not too sure. But if you're looking for browsing history you may have deleted you will be satisfied to know that all your history still remains on your computer (Deleted or Not). You can use progams that can dig up and find your browsing history from your Temp Internet Files.
