Hiking through this wonderful landscape is a joy for geoscientists and photographers alike, so no matter where your destination is, you’re bound to get distracted by an outstanding outcrop or spectacular view. Grand Canyon National Park is home to some of ...[Read More]

This week in GeoTalk, we’re talking to Simon Redfern, renowned scientist and science communicator and the man behind An Atom’s-Eye View of the Planet. What made you first step into science communication? That’s a difficult question for me to answer, since it is not a step that I have consciously recognised myself making. I suppose that I see science as having at least two sides. One is discovery… ...[Read More]

Hekla is one of the country’s most active volcanoes – both in terms of erupted material and eruption frequency, and lies at the heart of a 40 kilomet ...[Read More]
Imaggeo on Mondays: The name’s Bond. Hydrogen bond.
The O in H2O attracts electrons towards it, a property known as electronegativity. And because oxygen attracts electrons towards it, it is ever so slightly positive. Likewise, the hydrogen atoms in a water molecule are ever so slightly negative. The difference in charge across a water molecule is what holds water together as the slightly positive hydrogen atoms are attracted towards the slightly n ...[Read More]
