What is one reason why many geologists did not at first accept the theory of continental drift?
Ivan

The first reason was that his theory of continental drift was just too weak for most geologists to accept. Even though he believed the supercontinent that broke up into different continents moved, he did not have a clear explanation to how the continents moved. The other reason is that some of his explanation clashed with ideas that were widely accepted in the science communities. He used similar fossils from different continents to back up his theory of continental drift. However, at that time, many scientists that had observed similarities in fossils in places like South America and Africa believed there were similar fossils in different continents because of a land bridge that were formed by two continents.


Many science communities believe that land bridges allowed migration of many different species and even people to one place to another by large bodies of water frozen by low temperature known as ice age.

What is the definition of refraction, luminescence, and ultraviolet?
jeyben [28]
Refraction- bending of light waves (ex. straw in a cup of water looks bent on a side but really is NOT, this is due to refraction, it bends the light waves reflected)

Luminescence- Creation/Emission/Starting or making of light through ways that DO NOT INVOLVE heat.

Ultraviolet- a wavelength that is part of the electromagnetic spectrum its shorter than visible light waves.
