In this episode, we discuss impact craters, including how they are identified, the processes that occur within them, and how shockwaves from impacts can alter the magnetic characteristics of surrounding rocks.

Banusha Kugabalan, a geophysics PhD student at Imperial College London, joins us. She researches the shock remanent magnetisation in rocks and meteorites. The remanent magnetisation is the permanent magnetism preserved in rocks. As rocks form, the magnetic moments within crystals align with the Earth's magnetic field which can be used to date key events, such as the timing of meteorite impacts.

Enjoy!

In this episode, we outline the basics of plate tectonics.

What are plates? What are the types of boundaries between them? What is the "Ring of Fire"? Found out all this and more.

In this episode, we go through the hot topic of CO2.

We discuss where CO2 comes from and how it is removed from the atmosphere through natural and anthropogenic influences.

We also discuss the principles behind carbon capture and storage (CCS), including the geology required, its limitations, and how much CO2 storage is needed to reach climate targets.

Enjoy the episode.

Hello friends,

In this episode we go through the types of meteorites and the differences between asteroids, meteorites, meteors, comets, and so much more.

We discuss the latest scientific journeys to the rocky remnants in outer space, and what we could do if an asteroid was heading straight for Earth.

Enjoy!

Welcome to part 2 of Mass Extinctions.

Today we discuss the death of the dinosaurs, including how one huge asteroid changed the fate of life on Earth and how floods of lava created a catastrophic global warming.

We also discuss the possible mass extinction that is happening right now through human activities.

Earth's existence is full of dramatic events that have wiped

There is an established 'Big Five' mass extinction events, which include

1) Ordovician-Silurian (440 Ma)

2) Devonian (365 Ma)

3) Permian-Triassic (250 Ma)

4) Triassic-Jurassic (210 Ma)

5) Cretaceous-Tertiary (65 Ma) - goodbye dinosaurs.

We also ask the question: are we currently going through a sixth mass extinction?

In part 1 we cover the first four of these, including what are the geological time periods and should Jurassic Park be called as such.

Enjoy part 1!

In this episode we journey to the centre of Earth and back again, discussing the solid and liquid layers that make up our planet.

We talk about how the crust is the thinnest of layers floating on a ball of hot magma, and how interactions in the core generate a magnetic field that protects life on Earth and even changes the length of day. Enjoy!

Everyone knows what a rock looks like, whether it's a cliff face, a random boulder found on top of a hill, or your kitchen worktop. However, what actually are these weird and wonderful hard things?

This episode covers what makes up the rocks around us, as well as the different rock types, how they interlink in something known as the rock cycle, and so much more...
