∙ 13y agoWegener used similar fossils in Africa and South America as part of the argument for his theory of continental drift - that the continents were connected millions of years ago but then moved apart. Later we found out that his theory had some errors, but it was corrected and now we call it Tectonic Plates.

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.
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.
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.
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.
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.
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 do people not notice that continents drift?
Because they move so slowly that we can't feel it. It's a bit like why we can't feel the earth turning

What is 1 month calendar notice mean?
A 1 month calendar notice means that notice of an event, such as moving out of an apartment, based on the calendar. This means you would give notice on the 1st of the month if you wanted to move out on the 30th. This is different than a 30-day notice, where you could give notice on the 14th and move out on the 13th of the next month.
