## What do you learn in Introduction to Geophysics

Geophysics blends physics and math to study Earth's structure and processes. You'll explore seismology, gravity, magnetism, and heat flow. The course covers plate tectonics, Earth's interior layers, and geodynamics. You'll learn how to use geophysical methods to investigate subsurface features and natural resources. It's all about understanding our planet's inner workings through physical principles.

## Is Introduction to Geophysics hard?

Geophysics can be challenging, especially if you're not a math whiz. The concepts aren't too bad, but the calculations and problem-solving can get tricky. You'll need a solid grasp of physics and calculus. That said, most students find it manageable with some effort. The coolest part is applying abstract concepts to real-world Earth problems, which makes the struggle worth it.
