    Seismic waves are mechanical waves, meaning they need a medium—solid, liquid, or gas—to travel. Just like sound waves need air, seismic waves need the Earth’s interior or along it’s surface to move. When an earthquake occurs, energy is released from a specific point inside the Earth, called the focus (hypocenter). Right above this, on the…

This continuous process of rocks changing from one form to another is called the Rock Cycle, and it’s been shaping the Earth…

    Introduction to Geomorphology

    Let’s begin with the definition.Just split the word:Geo = Earth, Morpho = Form, Logy = StudySo, Geomorphology means “the study of Earth’s forms” — more precisely, it is the scientific study of landforms — the physical features you see on the Earth’s surface like mountains, valleys, plateaus, plains, etc. But it doesn’t stop at just…
