What did wegener notice about the continents?
Wegener noticed that the continents appeared to fit together like a jigsaw puzzle, especially when looking at the coastlines of South America and Africa. He also observed similarities in rock formations, fossils, and mountain ranges across continents that suggested they were once connected. This led Wegener to propose the theory of continental drift.
How did wegener's background as a climatologist contributed to his hypothesis that continents were once joined?
Wegener's background as a climatologist helped him notice similar fossil and rock formations, as well as ancient climates, on continents that are now separated by oceans. This led him to propose the theory of continental drift, suggesting that the continents were once joined together and have since drifted apart.
What did Alfred wegner notice about the outlines of the continents?
Alfred Wegener noticed that the outlines of the continents seemed to fit together like pieces of a jigsaw puzzle, particularly the coastlines of South America and Africa. This observation led him to develop the theory of continental drift.
How did Wegener's background as a climatologist contribute to his hypothesis that the continents were once joined?
Wegener's background as a climatologist helped him notice similarities in rock formations, fossils, and geological structures between continents separated by vast oceans. He realized that these similarities could not be explained by existing theories about seafloor spreading or continental drift. This led him to propose the groundbreaking theory of continental drift, suggesting that the continents were once connected and have since moved apart.
What do all continents have in common that paleontologists notice?
All paleontologists,(and other people), notice that on every continent, there were similar fossils. Obviously, not all prehistoric/Precambrian organisms could swim all the way across oceans, so the continents had to have moved. This proved Wegener's hypothesis(some really old scientist i learned about in science class)which was continental drift.
Is it true or false geographers of the 1500 were the first to notice that some continents seem to fit together?
False. The concept of continental drift and the idea that continents could fit together like pieces of a puzzle was proposed in the early 20th century by Alfred Wegener, a meteorologist, not by geographers in the 1500s.
Why is the Moon's gravity unable to move the continents?
It actually does. It moves our oceans and continents everyday. You just don't notice it as the movements are very small.
Why do people not notice that the continents drift?
People generally do not notice that the continents drift because they move so slowly. People do notice earthquakes and other natural disasters that are sometimes caused by the movement of the earth's tectonic plates.
What did mapmakers notice about the shape of the continents?
Mapmakers noticed that the shapes of continents appeared to fit together like pieces of a jigsaw puzzle, suggesting they were once joined together. This observation contributed to the development of the theory of continental drift and later the theory of plate tectonics.
What do people notice about rainbows?
Some things people notice about rainbows are the different colors, size, its location, and where it appears to start and end.
You notice that your daughter is different from other girls her age?
