Why were the modern clues not available in wegeners time?
During Wegener's time, modern clues such as advancements in technology and research methods were not available. Additionally, the scientific community at that time did not widely accept the theory of continental drift proposed by Wegener, which limited the exploration and investigation of supporting evidence.
What paleo climatic evidence for polar wandering?
Layers of glacial deposits are found at same place in sequence of rocksNote directions of glacial ice movement as indicated by striations or grooves in the rock
What evidence do the scientists have to support the idea that continents were once a large landmass?
The evidence scientists have are fossil clues, plant clues, climate clues and rock clues. Fossil clues supported the idea because a certain fossil the Mesosaurus was found in two continents on opposite sides of the Earth and the only reason for that is if the lands came together at one time. Plant clues support the idea the same way fossil clues do, like the plant called a Glossopteris was found in different areas around the world. Climate clues support the idea because some of the fossils and plants from warmer climates were found in the Arctic. That explains why there are glaciers in tropical areas. Lastly rock clues support the idea because if the continents were once connected at one time, then the rocks that made up the continents should be in the same locations where they were joined.
How do rock climate and fossil clues support the hypothesis of continental drift?
Rock clues support Wegners theory of continental drift and Pangaea because when India hit Eurasia the Himalayas formed and that is where Mt Everest is today! Climate clues include glacial evidence in tropical places it shows glacial evidence that there was once glaciers there. Fossil clues in clue many tropical plants and animal fossils were found in places like Antarctica where these plants and animals could not grow. Also dinosaur bones were found scattered around there earth. Dinosaurs can't swim, so they must have walked around this way!
What Rock clues were used to support the theory of continental drift because .?
parts of the Appalachian Mountain of the eastern US are similar to those found in Greenland and western Europe. Rock clues like these support the idea that the continents were connected in the past.
What is the theory shown to be correct by age evidence and magnetic clues?
Magnetometer
What theory is shown to be correct by age evidence and magnetic clues?
Magnetometer
Is plate tectonics the main lines of evidence are fossils climate clues rock and the theory of seafloor spreading?
Yes, plate tectonics is supported by various lines of evidence such as fossils showing similar species on different continents, climate clues like ancient glaciers in tropical regions, rock formations matching across continents, and the theory of seafloor spreading confirmed by magnetic striping on the ocean floor. These pieces of evidence collectively support the concept of plate tectonics and the movement of Earth's lithosphere.
What evidence in rocks supports the theory of seas-flooring spreading?
1.) The age of the rocks- the oldest ones are found further away from the original mid-atlantic ridge. 2.) Magnetic clues. The rocks with iron in them have shown that the Earth's magnetic field has reversed itself several times. It is imprinted in the rock.
How do scientist discover theories?
they work in there lab and find all the evidence they can get and then put all the clues together to make a theory
Clues available at a scene is called?
Evidence.
How does seafoor age and magnetic clues support seafloor spreading?
Seafloor is youngest near the mid-ocean ridges and gets progressively older as you move away from the ridge. Magnetic stripes on the seafloor provide evidence of seafloor spreading, as they show alternating patterns of normal and reversed magnetic polarity that match the Earth's magnetic reversals over time. This supports the theory of seafloor spreading as new oceanic crust is created at the mid-ocean ridge and spreads outward.
What is another name for clues?
hints clues can also be called evidence.
What does texts clues mean?
Text clues means evidence and details
What are wegeners clues of the jigsaw puzzle?
Wegener's clues for the theory of continental drift included the fit of the continents like a jigsaw puzzle, matching rock formations and mountain ranges across continents, and similarities in plant and animal fossils found on different continents. These clues provided evidence for the movement of the continents over time.
How is earth's history interpreted and recorded?
Like a detective story Earth's history is recorded in many clues and bits of evidence available to trained observers. These include:GeographyGeoogyRadiocarbon datingChemistryAstrophysicsAstronomyThe clues are found in rocks, magnetic traces, mineral deposits, meteors, the sun, the moon, cooled lava, and similar.
What is the synonym for 'ruin the evidence'?
destroy the incrimating clues
