## What do you learn in Geophysics

Geophysics explores the Earth's physical properties and processes using physics principles. You'll study seismology, gravity, magnetism, heat flow, and plate tectonics. The course covers methods for imaging Earth's interior, understanding natural hazards, and exploring for resources. You'll learn about geophysical instruments, data analysis, and computer modeling to investigate our planet's structure and dynamics.

## Is Geophysics hard?

Geophysics can be challenging, especially if you're not a fan of math and physics. It combines complex concepts from geology, physics, and math, which can be a bit overwhelming at first. But don't worry, it's not impossible. With some effort and practice, you can get the hang of it. The toughest part is usually wrapping your head around the abstract concepts and applying them to real-world scenarios.
