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.

A food handler does not need to worry about time and temperature
alukav5142 [94]

This is to prevent spoilage from happening because the changes in temperature in which the food is exposed has something to do with the development of certain kinds of bacteria that can be harmful to a person's health.
