The process in which sedimentary rocks are arranged in layers is known as

Fossils help us to understand

Fossil record is helpful to tell us that how was the life millions of years ago.

Fossils are found mostly in which type of sedimentary rock?

• Fossils are preserved remains of ancient plants and animals.
• Can be in the form of Rocks.
• Can be impressions.

Which type of fossil is formed when minerals fill in the space left from a living organism?

What happens to insects when they get trapped in amber?

The Fossils in which any small organism trapped in resin of tree which becomes rigid after burring in soil are called Amber fossils.

This is an example of    

• Fossils changed by minerals are said to be mineralized.

Which of the following statements is true about fossilization?

• Harder parts made up of carbon compounds which doesn't decay or destroy easily.

The picture shows which type of fossil?     

• Imprint fossils don't contain any carbon material.
• These include coprolites, foot print, plants or track etc.

Which of the following objects is most likely to become a fossil?

• Hard parts are made up of calcium carbonate and other elements so can't be destroyed or decayed even in diverse conditions easily.
• So the parts are most likely to be fossils.

__________ are remains of ancient plants and animals.

• Fossils are used by paleontologists to know about ancient world.
• Fossils tell us about history of life on earth.

In the case of fossils, what is amber?

• Amber fossils are made up of hardened tree sap.
• It has whole organism trapped in it.

When parts of an organism like feathers or leaves of a tree leave imprints, then the fossilization is known as

• The Fossils give knowledge about history of life on earth.
• Knowledge of the ancient world.

Rocks formed from sediments are called

• The rocks can be on surface of earth or maybe near the earth surface.

When the minerals from sediments replace tissues of an organism, __________ fossilization has occurred

Which of the following is true about fossils?

• Fossils can be of different types like mineralized fossils, casts and molds, impression fossils etc.

A dead organism is more likely to become a fossil if it contains _________ parts like teeth or bones.

• Fossils are the preserved parts for many years so the parts have ability to resist decaying can become fossils only.
• Hard parts of organisms like shells, bones and teeth etc are made up of calcium carbonate which is very strong.
• So the hard parts have greater ability to don't decay and become fossils than the soft parts.
• As a result, an organism is more likely to become fossil if it contains Hard parts as compared to soft parts.
