## What do you learn in Geochemistry

Geochemistry explores the chemical composition of Earth and other planets. You'll study the distribution and movement of elements in various geological systems, from rocks and minerals to oceans and atmospheres. The course covers isotope geochemistry, thermodynamics, and the chemistry of natural waters, giving you a solid understanding of how chemical processes shape our planet.

## Is Geochemistry hard?

Geochemistry can be challenging, especially if you're not a fan of chemistry or math. It involves a lot of complex concepts and calculations, which can be overwhelming at first. But don't worry, most students find it manageable with consistent effort. The key is to stay on top of the material and practice problem-solving regularly. It's definitely not a walk in the park, but it's not impossible either.
