After four fascinating instalments in the known unknowns series we have (sadly) come to the final post. Since the series began in September we have explored the top questions that still remain unanswered when it comes to understanding the inner workings of the planet as well as how the interplay of a number of systems that occur at the Earth’s surface give rise to its varied landscapes. The series ...[Read More]

Thinking of the Arctic conjures up images of vast expanses of white icy landscapes punctuated by towering icebergs and a few dark rocky masses; certainly not a green landscape with a series of water pools amongst rolling hills. The image below is perhaps more reminiscent of the temperate Scottish or Welsh countryside; but don’t be fooled, out Imaggeo on Monday’s image was captured by Reinhard Pien ...[Read More]
The known unknowns – the outstanding 49 questions in Earth Sciences (Part IV)
We are coming to the end of the known unknowns series and so far we have explored issues which mainly affect the inner workings of our planet. Today we’ll take a look at the surface expression of the geological processes which shape the Earth. Topography significantly affects our daily life and is formed via an interplay between primarily tectonics and climate, but it also affected by biological, ...[Read More]
Imaggeo on Mondays: Paramo Soil
What lies between 3000m and 4800m above sea level in the mountains of the Andes? A very special place dominated by an exceptional ecosystem: The Páramo. Picture lush grasslands with a unique population of flora and fauna, some of which is found nowhere else on Earth. Páramos stretch from Ecuador to Venezuela, across the Northern Andes and also occur at high elevation in Costa Rica. The climate her ...[Read More]
