All Things Volcanic
Our hill, Somlo is a 6m year old extinct volcano. Here are some pictures of what it might have looked like when it was active - and what it looks like now…
Between 720 and 640 million years ago, Earth was thought to be entirely frozen, with global temperatures reaching -50°C (-58°F). This hypothesis, known as “Snowball Earth,” is actually quite controversial, as geoscientists cannot agree on whether or not it actually happened based on the available evidence.
In the inner Solar System, the biggest volcano we know of is Olympus Mons on Mars, 624 kilometers (374 miles) across and 25 kilometers (16 miles) high. But what about in the outer Solar System? Well, that record might now belong to Pluto. If a feature known as Wright Mons on this dwarf planet is confirmed as a volcano, it will take the title of the biggest such feature beyond Mars.
