Which was used by Wegner to establish the continental drift?
Alfred Wegener used evidence from the fit of continents, distribution of fossils, rock types, and ancient climate data to support his theory of continental drift.
What were the four types of evidence Wegener showed to prove his theory?
Wegener showed evidence of similar rock formations and mountain ranges on different continents, evidence of matching plant and animal fossils on different continents, evidence of matching glacial deposits on different continents, and evidence of matching ancient climates on different continents to support his theory of continental drift.
What fossil is preserved in ice and snow?
In theory, any kind of fossil can be preserved in ice, but among prehistoric animals, the most commonly found preserved in ice are mammoths and mastodons. We know exactly what a woolly mammoth looked like because entire specimens, hair and all, have been found frozen (the details of hair or skin most dinosaurs are depicted with is basically guesswork).
What were the 3 types of evidence the Alfred Wegener used to support his theory of Continental Drift?
Alfred Wegener used fossil evidence, geological evidence, and paleoclimatic evidence to support his theory of Continental Drift. Fossils of the same species found on different continents, similar rock formations and mountain ranges across continents, and matching ancient climate patterns were key pieces of evidence that he presented.
What are three types of evidence for Pangaea?
Fossil evidence: identical fossils of plant and animal species have been found on continents that are now separated by oceans. Geologic evidence: similar rock formations and mountain ranges are found on opposite sides of different continents. Climate evidence: ancient climate patterns inferred from glacier deposits and coal deposits match up when continents are repositioned together as Pangaea.
What types of evidence of ancient life can preserved as fossils?
Fossils can be made of any material that deteriorates slower than the sediment that forms the fossil hardens
What types of fossils forms wheather there are microbes are present or not?
Fossils can form even if microbes are not present. Microbial fossils, such as stromatolites, can form when microbes are present and leave behind structures or chemical signatures that are preserved in the rock record. Non-microbial fossils can include the preserved remains of plants, animals, or other organisms from ancient environments.
What is so nice about fossils that have been encased in amber or ice?
Fossils encased in amber or ice are well-preserved, offering unique insights into ancient ecosystems and organisms. The amber fossils often capture minute details due to the clarity and protection provided by the resin. Ice fossils can include soft tissues and DNA that are usually not preserved in other types of fossils due to rapid freezing.
How do scientist learn about plants that are extinct?
Scientists can learn about extinct plants through fossils, pollen records, and ancient DNA analysis. Fossils provide direct physical evidence of past plant species, while pollen records give insights into the types of plants that existed based on the pollen grains preserved in sediments. Ancient DNA analysis can also reveal genetic information about extinct plants by extracting and sequencing DNA from preserved specimens, providing a deeper understanding of their evolutionary history.
What are types of evidence that suggest that evolution has occurred?
The two types are Dna, and fossils

How are amber fossils the same from regular fossils?
Amber fossils are preserved in hardened tree resin, while regular fossils are preserved in rocks. Both types of fossils capture the remains of ancient organisms, providing important insights into the past. Amber fossils often preserve delicate details and even soft tissues due to the protective properties of the resin, making them particularly valuable for scientific study.
Explain the difference between trace and body fossils?
Trace fossils refer to evidence of ancient life that is not the actual remains of an organism, such as footprints, burrows, and coprolites (fossilized feces). Body fossils, on the other hand, are the actual remains of an organism, such as bones, teeth, and shells. Both types of fossils can provide important information about ancient life and the environments in which they lived.
What contains different kind of fossils?
Rocks, sediment, and soil contain different kinds of fossils, which are the preserved remains or traces of ancient plants and animals. Fossilized bones, shells, imprints, and tracks can all be found in various types of sedimentary rocks.
Preserved remains of plants or animals are called?
Sometimes they are referred to as bits of dead plants or animals. Others refer to them as fossils, or organic remains. If it is a decayed organism (either plant OR animal) it might be referred to as 'detritus'. If it's the final remains of a human being, it may be referred to as a corpse.
Which was used by Wegner to establish the continental drift?
