S2 E4 What on Earth Are Igneous Rocks?!

What on Earth?! ·

2026/09/24

In this episode of What on Earth?!, we’re going beneath the surface to find out where igneous rocks actually come from. Is there really a giant layer of magma hiding beneath our feet? If most of Earth’s mantle is solid, where does magma come from? And why can one magma produce gentle lava flows while another feeds explosive volcanoes? Together, we follow the journey from solid mantle to molten magma and, eventually, igneous rock. We explore decompression melting beneath mid-ocean ridges...

What on Earth are sedimentary rocks?! You probably encounter them every day without thinking twice. But how does loose sand, mud, or even the remains of ancient organisms become solid rock? In this episode of What On Earth?!, we dive into the world of sedimentary rocks and explore how they form, what they can tell us about the environments of the past, and why they are so important for understanding Earth’s history. We look at how sediments are produced, transported and deposited before event...

What On Earth is Evolution?!

What on Earth?! ·

2026/05/21

Evolution is everywhere in science and almost nowhere in popular culture is it explained clearly. In this episode of What On Earth?!, we dive into some of the biggest misconceptions about evolution and separate the science from the myths. Is evolution “just a theory”? Did humans really evolve from monkeys? Is evolution completely random? And does evolution explain how life first began? These are questions many people have heard, but the answers are often far more interesting than the misconce...

Fossils aren’t just dinosaur bones in museums; they’re one of the main ways we know what life on Earth looked like millions of years ago. In this episode, we dive into what fossils actually are, how they form, and why finding one is such a rare and special event. We explore the different types of fossils, from bones and shells to footprints and burrows, and explain the processes that turn living organisms into stone. You’ll also learn why the fossil record is far from perfect: why some organi...

In our second episode of What on Earth, we dive into the building blocks of our planet - minerals and rocks - and clear up some of the most common confusions right from the start. We begin by asking a deceptively simple question: what exactly is a mineral? From there, we walk through the key criteria a substance needs to meet to earn that title - naturally occurring, solid, ordered, and chemical (yes, science does love its rules). Once the minerals are sorted, we zoom out and talk about rocks...

In our very first episode of What on Earth, we take you on a small journey through the language of science: from the days when Latin ruled academia to how English eventually became the global scientific language we use today. Along the way, we realise that science doesn’t exist in a vacuum - wars, politics, and historical turning points have shaped not only what we study, but also how we communicate it. We also get honest about one of the biggest challenges we face as scientists: explaining c...
