Fossil Quiz

What are fossils primarily considered to be?

• Future predictions of animal evolution

• Remains of organisms from millions of years ago

• Recent biological discoveries

• Hypothetical concepts in science fiction

Which of the following can be a form of fossil?

• A fully preserved insect in amber

• A plastic replica of a dinosaur

• A digital model of an ancient plant

• A fresh sample of oceanic algae

How do geologists determine the age of a fossil?

• By estimating the size of the fossil

• By the depth at which the fossil was found

• By studying the breakdown of radioactive isotopes in the rock

• By comparing it to similar fossils

What condition is necessary for the fossilisation process ?

• Presence of high oxygen levels

• Absence of oxygen and bacteris

• Constant high temperatures

• Abundant bacterial activity

How do high temperatures affect the organisms responsible for decay according to the text?

• They increase the rate of decay

• They have no effect on the organisms

• They destroy proteins which kills the organisms

• They promote bacterial respiration

What is the first step in the fossilisation process ?

• The animal or plant is exposed due to erosion.

• Organisms die.

• Water seeps into the hard remains.

• Sediment builds up and applies pressure.

What happens to the hard parts of the organism during the fossilisation process?

• They are immediately exposed on the surface.

• They dissolve and minerals are left in their place.

• They are buried under volcanic ash only.

• They turn into sedimentary rocks without any mineral replacement.

How long does the fossilisation process take as described in the image?

• A few decades.

• Hundreds of years.

• Thousands of years.

• Millions of years.

What do some fossils represent ?

• Actual organisms that lived in the past

• Traces of past events left behind by organisms

• Modern artifacts mistakenly identified as fossils

• Geological formations unrelated to biological activity

What is a necessary condition for fossil formation according to the text?

• High temperature

• Absence of oxygen and water

• Presence of sunlight

• Rapid cooling
