Geologic Time Tulane University

The goal of this lecture is come to come to a scientific understanding of geologic time and the age of the Earth. In order to do so we will have to understand the following: The difference between relative age and numeric age. The principles that allow us to determine relative age (the principles of stratigraphy).

Volcanic Landforms, Volcanoes and Plate Tectonics

Volcanic landforms are controlled by the geological processes that form them and act on them after they have formed. Thus, a given volcanic landform will be characteristic of the types of material it is made of, which in turn depends on the prior eruptive behavior of the volcano. Although later

Differences Between Extrusive and Intrusive Rocks Sciencing

Apr 13, 2018 · The most obvious difference between extrusive rocks and intrusive rocks is crystal size. Because extrusive rocks cool quickly, they only have time to form very small crystals such as basalt or none at all. On the other hand, intrusive rocks grow larger crystals because they take longer to cool.
