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.
Red blood cells contain enormous amounts of a protein called hemoglobin. This iron-containing molecule binds oxygen as oxygen molecules enter blood vessels in the lungs. Hemoglobin is also responsible for the characteristic red color of blood.
