Geoscience is concerned with the study of the physical structure and processes of the earth and planets.
Our world has entered a period of environmental crisis and rapid transition. Because of this, formerly traditional career paths in the geo (earth) sciences have been modified as world governments, industries and social structures react to many forms of global change. Canadian expertise is already at the forefront of geoscientific fields throughout the world and Canadian earth scientists will spearhead research into many new challenges.
Today, more than ever, the geosciences have taken on a multi-faceted role. You can enter a number of fields depending on your interests, where you want to work and how much you want to earn.
There are many resources available on the internet.
