Which statements describe the fossil record check all that apply?

Answer: The fossil record shows which organisms have a common ancestor. The fossil record gives evidence of extinct species. The fossil record documents changes in organisms over time.

What does the fossil record give evidence for?

The Fossil Record Fossils provide evidence that organisms from the past are not the same as those found today, and demonstrate a progression of evolution. Scientists date and categorize fossils to determine when the organisms lived relative to each other.

How would you describe the fossil record?

A fossil record is a group of fossils which has been analyzed and arranged chronologically and in taxonomic order. Fossils are created when organisms die, are incased in dirt and rock, and are slowly replaced by minerals over time.

Which statement best describes the fossil record Brainly?

The correct answer choice is answer B.) The fossil record provides evidence of a common ancestor to many species. Hope this helped!

Which best describes the fossil records?

Explanation: A fossil is a traces or remainings of plants and animals that lived in the past. The fossil record provides evidence of a common ancestor to many species is the option that best describes the fossil record.

How are fossils formed 3 steps?

Stage 1: A dinosaur dies and is buried before the remains are completely destroyed. Stage 2: Over time, layers of sediment build up and press down on the buried remains. Stage 3: Dissolved minerals, transported by ground-waters in the sediment, fill tiny spaces in the bones.

What are the 5 stages of fossilisation?

Fossils form in five ways: preservation of original remains, permineralization, molds and casts, replacement, and compression.

What event happens first when a fossil is made?

Fossil formation begins when an organism or part of an organism falls into soft sediment, such as mud. The organism or part then gets quickly buried by more sediment. As more and more sediment collects on top, the layer with the organism or part becomes compacted.

Why are hard body part fossils more commonly found in the fossil record?

When an organism is buried quickly, there is less decay and the better the chance for it to be preserved. The hard parts of organisms, such as bones, shells, and teeth have a better chance of becoming fossils than do softer parts. One reason for this is that scavengers generally do not eat these parts.

Under which conditions would a fossil most likely form?

The animal is likely to be fossilized only if it is buried soon after it dies (or when it is buried alive!). Even then, it is likely to decompose, because water that seeps through the sediment around it usually is rich in oxygen. Sometimes, however, the body is buried rapidly by fine mud.

Is it possible to determine the age of a fossil?

To establish the age of a rock or a fossil, researchers use some type of clock to determine the date it was formed. Geologists commonly use radiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and carbon, as reliable clocks to date ancient events.

What are 4 ways a fossil can be destroyed?

Once buried, the fossil and surrounding rock might undergo extreme pressure and heat, and the fossils could melt. Once fossils are formed, they might be washed away by streams, moved by glaciers, carried by scavengers, or caught in rockslides. Weathering by wind, water, and sun can destroy a fossil by wearing it away.

What are three ways in which a fossil can be destroyed after it has formed 1?


  • Melting – Changing its appearance by converting its original physical form.
  • Colliding or pressurizing fossils: Physical way of destroying fossils.
  • Changing its natural conditions: Wear out the natural agents which makes it difficult to preserve.

What is the difference between fossilized and petrified?

When a fossil organism is subjected to mineral replacement, it is said to be petrified. For example, petrified wood may be replaced with chalcedony, or shells replaced with pyrite. This means that out of all fossils, only the creature itself could be fossilized by petrification. But “petrified” has a nice sound to it.

How do you know if something is petrified?

Keep an eye out for little bits of sap or sap-like colors like red (often strong reds), orange, and tan around the smooth parts. Smooth sections are often 3 to 5 inches (7.6 to 12.7 cm) in length. If the specimen has no bark but looks and feels like wood, it’s probably petrified.

What is an example of a petrified fossil?

Permineralization or Petrification – After an organism is buried, minerals carried by water such as silica, calcite or pyrite replace the organic material in the fossil. Some common examples are most dinosaur bones, petrified wood, and many trilobite fossils.

What are 3 different types of fossils?

This week’s homeschool science corner is all about the three main types of fossils. Scientists categorize fossils into three main groups – impression fossils, trace fossils, and replacement fossils. Amber is also often looked at as a fourth type of fossil.

How many years does it take to make a fossil?

10,000 years

What is the oldest fossil on record?


What is the oldest fossil ever found?

Scientists discovered what they thought were 3.5 billion-year-old fossils in western Australia almost 40 years ago. A new study reveals that these rocks did indeed contain organic life — making them the oldest fossils ever found.
