Why is the fossil Glossopteris evidence of Gondwana?

Glossopteris is a plant fossil that was found in multiple continents that were once part of the supercontinent Gondwana. The widespread distribution of Glossopteris across these continents suggests that they were once connected, providing evidence for the existence of Gondwana.

What is theory for fossils of tropical plants found on an island in the arctic ocean?

The theory for fossils of tropical plants found on an island in the Arctic Ocean is that the island was once situated in a tropical or subtropical region, and through the movement of tectonic plates, it shifted to its current location in the Arctic. This suggests that the climate of the island has significantly changed over time due to the shifting of the Earth's landmasses.

Are fossils examples of organic matter and why?

Yes, fossils are examples of organic matter because they are the preserved remains or traces of once-living organisms. Fossils can include bones, shells, teeth, and other organic materials that have undergone a process of mineralization or replacement with inorganic materials to become stone-like structures.

What kind of rock did you find?

I found a piece of igneous rock, which is formed from cooled and solidified magma. This rock typically has a crystalline structure and may contain minerals such as quartz, feldspar, and mica.

When did abundant fossil evidence first appear in the geologic record?

Abundant fossil evidence first appeared in the geologic record during the Cambrian Period, around 541 million years ago. This period is known as the "Cambrian Explosion" because it marked a rapid diversification of marine life and the emergence of many major animal groups.

What are the four step scientists use to study fossils?

Scientists use the following four steps to study fossils: 1. Excavation - careful digging to uncover fossils, 2. Preparation - cleaning and preserving fossils, 3. Description - documenting physical characteristics of fossils, and 4. Analysis - using various methods to interpret the fossils' age, environment, and relationships to other organisms.

Why old buildings should be preserved?

Old buildings should be preserved because they often hold historical significance, cultural value, and architectural beauty. They can serve as important reminders of a community's past and contribute to its sense of identity and heritage. Preserving old buildings also helps to maintain a connection to the past and can attract tourism and economic development.

Is it impossible to date a fossil with any certainty?

Well, it depends on how much detail you want. Carbon-dating is actually very accurate to within a few thousand years. This sounds like a long time to us, but when you are talking about a fossil that is millions of years old, a few thousand years is nothing. Of course, you can't say that a fossil has been in the ground since 1:27pm, Monday 5th June, 34,050,389 BC, but considering the time scales involved, we can date fossils pretty accurately.

How do you beat the trainers in rock tunnel?

What is the study of fossils and extinct organisms called?

The study of fossils and extinct organisms is called paleontology. It involves the identification, classification, and interpretation of fossils to understand the history of life on Earth.

What do you do after got a fossil on Pokemon emerald?

you take the fossil to rustboro city and take it to the building where you got the POKENAV talk to the guy on the 2nd floor in the bottom right hand corner, give him the fossil and go talk to Mr.Stone. After that go to the same guy yougave the fossil to and he will give you a ancient pokemon. claw fossil:anorith root fossil:lileep

Why some extinct plants and animals not fossilized?

Not all organisms are fossilized because specific conditions are required for fossilization to occur. Factors such as rapid decay, scavenging, and weathering can prevent an organism from being preserved as a fossil. Additionally, some organisms may have soft body parts that do not lend themselves well to fossilization.

What is special about the fossils of the burgess shale?

The Burgess Shale fossils are special because they preserve soft tissues and detailed body structures of ancient marine organisms from over 500 million years ago. These exceptionally well-preserved fossils provide insights into the early evolution of complex life forms during the Cambrian Explosion.

When tiny spaces inside a fossil are filled in with minerals you have what kind of preservation?

You have what is known as permineralization preservation when tiny spaces inside a fossil are filled in with minerals. This process can result in the fossil being preserved in great detail, often retaining the original structure of the organism.

How does fossils show us that life on earth has changed?

fossils are the remains of the living organisms that existed a long time ago. They are well preseerved by nature and are vital for us as they enable us to know about the living conditions in which they existed. They tell us about the phases of evoultions through which they must have undergone in order to sustain themselves in the competetive environment. The fossils can tell us about the species's evolution and its adaption towards the environmental condition and thus help us in understanding the natural selection easily. natural selection is the theory given by Darwin about the evolution of species.fossils are the remains of the living organisms that existed a long time ago.

What are three ways fossils can be preserved?

There's only one way that they can be formed over millions of years. An animal dies, it soon is compressed with heat/pressure and turns to sediment. The only other way is if you want to make a false fossil. Just use plaster.

Accualy, no. fossils can be formed by....

1. sediment piling on the substance and creating a mold

2. an orginism may be incased in ice, which counts as a fossil

3. mud, bogs, and mucky water may presurve an orginism

4. heat and pressure makes a metamorphic rock, and only sedimentary rock can weild fossils

HOPE I HELPED ^^ IF I DID CHECK OUT JEALOUSNOTAHATER ON YOUTUBE, SUBSCRIBE, RATE, AND COMMENT TOO.

I kept his answer so you could see how wrong he is lol :)

oh, they can also be incased in amber, a sticky substance that ozzes out of trees to protect them from paricites

What are the two types of rocks would you find near a volcano and why?

Igneous - is found deep inside the Earth, where it's hot, it's hot enough to melt rock. After a while it cools down. As it cools it forms igneous rock. Igneous contains randomly interlocking crystals. Igneous rocks like basalt and granite non-porous and so very hard and tough.

Metamorphic Rock - the temperature for metamorphic rock is hot enough to mold rock under pressure, but not enough to melt it. The difference for metamorphic rock is that the crystals are arranged in layers. That's due to the high pressure. Slate is metamorphic rock formed from shale, and marble is metamorphic rock formed from limestone.

What is developed by chemists to supplement fossil fules?

Renewable energy sources like solar, wind, and hydroelectric power are developed by chemists to supplement fossil fuels. These alternatives are more sustainable and environmentally friendly, helping reduce reliance on non-renewable resources. Chemists also work on developing biofuels from sources like algae or waste materials as a renewable energy option.

This type of fossil is formed when an organism is buried in sediment which hardens into rock After the soft parts of the animal rot away a cavity remains?

The type of fossil being described is a mold fossil. These fossils preserve the external shape of an organism by filling in the cavity left behind after the original organism decays. Mold fossils provide important insights into the shape and size of ancient organisms.

What is most likely to have a well-preserved fossil record?

Hard structures like bones or shells are more likely to be well-preserved in the fossil record compared to soft tissues. Organisms that lived in environments conducive to fossilization, such as those with frequent sedimentation or low oxygen levels, are also more likely to have well-preserved fossils.

Is The geologic time scale divided by major changes in the fossil record true?

Yes, the geologic time scale is typically divided based on major changes in the fossil record, called biostratigraphy. These divisions are used to categorize different periods in Earth's history based on the types of organisms that lived during that time.

Are they making a new fossil fighter?

Fossil Fighters: Frontier released in America March 20th, 2015. Whether or not the franchise will continue after this remains to be seen.

Which conditions are best for fossil formation?

Probably the best condition for fossil creation/preservation would be aqueous catastrophism(ie... flood), stratum deposited in rapid succession. Quick coverage of plant or life form would/do present terrific fossils.

The answer of 'Quick freezing' is not so likely. I can't think of anywhere there would suddenly be 'flash freezing' upon our planet. Life forms would have a chance to move away from such conditions of cold and plants would die out. Although death within a cold temperature area would lend to good preservation of a life form.
