What are fossils short answers 6?
Fossils are the remains or traces of ancient life that have been preserved by natural processes. Examples of fossil include shells, bones, stone imprints of animals or microbes, exoskeletons, objects preserved in amber, petrified wood, coal, hair, oil, and DNA remnants. … Body Fossils.
What are called fossils?
Fossil, remnant, impression, or trace of an animal or plant of a past geologic age that has been preserved in Earth’s crust. The complex of data recorded in fossils worldwide—known as the fossil record—is the primary source of information about the history of life on Earth.
What are fossils in history?
A fossil is physical evidence of a prehistoric plant or animal. This may be their preserved remains or other traces, such as marks they made in the ground while they were alive. Fossilised remains – including fossil bones and teeth – are known as body fossils. Fossilised shells are also body fossils.

What is the study of fossils?
Fossils are the geologically altered remains of a once-living organism and/or its behaviour. … The study of fossils is called paleontology, from the Greek meaning ‘ancient (paleo-) being (onto-) study (-logy)’. Scientists who study fossils are called paleontologists.
What are fossils class 10th?

Where is fossil found?
Fossils are usually found in sedimentary rock (sand, silt or clay that settles to the bottom of an ocean or lake and compresses). Fossils have been found on all continents, but mostly in North and South America, and Asia.
How is fossil formed?
Fossils are formed in different ways, but most are formed when a plant or animal dies in a watery environment and is buried in mud and silt. Soft tissues quickly decompose leaving the hard bones or shells behind. Over time sediment builds over the top and hardens into rock.

Over time, layers of sediment build up and press down on the buried remains. Dissolved minerals, transported by ground-waters in the sediment, fill tiny spaces in the bones. The combination of pressure, chemical reactions and time eventually turns into minerals fossils.

What are the 3 conditions necessary to form fossils?
What conditions favor the formation of fossils? How might this cause the fossil record to be biased? The organism generally must have hard parts such as shell, bone, teeth, or wood tissue; the remains must escape destruction after death; and the remains must be buried rapidly to stop decomposition.
