Answer: Fossils are any impressions or imprints left by some previous organism in soft mud or sedimentary rocks, which subsequently hardened. Fossils are also moulds and casts of entire organisms that got preserved. Fossils are documentary evidences of organic evolution.
What are fossil fuels Class 7?

What are fossils Class 11?
Fossils are the remains or impressions of a very old plant, animal or human which have turned into stone. These are often embedded in rock, and are thus preserved for millions of years. 364 Views.
What is rock short answer?
A rock is a solid made up of a bunch of different minerals. Rocks are generally not uniform or made up of exact structures that can be described by scientific formulas. Scientists generally classify rocks by how they were made or formed. There are three major types of rocks: Metamorphic, Igneous, and Sedimentary.
Why are fossils found in sedimentary rocks Class 7?
A. Sedimentary rocks: these are also called as layered or sedimentary rocks. When the sediments get aggregated and compacted they form sedimentary rocks. These sediments come from the older rocks, plant and animal remains and therefore they contain animal and plant fossils.
Where do fossils come from?
Fossils are typically found in sedimentary rocks and occasionally some fine-grained, low-grade metamorphic rocks. Sometimes the fossils have been removed, leaving moulds in the surrounding rock, or the moulds may have later been filled by other materials, forming casts of the original fossils.

What are fossil fuels Class 10?
A natural fuel formed deep under the earth from the pre-historic remains of living organisms (like plants and animals) is called a fossil fuel. Coal, petroleum and natural gas are fossil fuels. Fossil fuels are dug out from the earth.
What is fossil Class 8?
Fossil means Remains of Dead Plants and Animals obtained millions of years ago.
What is fossil science class 8?
A fossil fuel is a fuel formed by the decomposition of buried dead organisms under the pressure and heat in the earth’s crust. It takes millions of years for organic matters to chemically alter and form fuels. Fossil fuel is continuously formed by natural process. … It is a combustible sedimentary rock.
What are fossil fuels Class 6?
The natural resources which are formed from the dead remains of living organisms (fossils) are all known as fossil fuels. Coal, natural gas and petroleum are examples of fossil fuels.
What is fossil in botany?
A fossil is the mineralized partial or complete form of an organism, or of an organism’s activity, that has been preserved as a cast, impression or mold. A fossil gives tangible, physical evidence of ancient life and has provided the basis of the theory of evolution in the absence of preserved soft tissues.
Do you mean by fossil?
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 body fossils?
Fossils are classified as either body fossils or trace fossils. Body fossils were parts of the organism, such as bones or teeth. Trace fossils include foot impressions, eggs, burrows, and dung. Objective. In this activity, students will learn to distinguish between body fossils and trace fossils.
