In the 1960s, new evidence helped support the theory of continental drift and change it into the theory of plate tectonics. What
was this new evidence? Rock patterns and glacial deposits in similar climates.
The African and South American coastlines are similar, providing evidence of their common origin.
Fossils disproving the continent of Pangaea.
The location of the plates was determined by locating their boundaries, using data on the Earth’s magnetic field.
Due to the fact that Africa and South America do not have similar coasts, fossils prove that used to be the continent of Pangaea, and location of the plates had boundaries, but they were not affected by Earth's magnetic fields.
A population decrease in primary producers would affect the ecosystem negatively because everyone who ate the primary consumers would have a lack of food.
