You think you are a geek and know everything about the Earth?

Well then, did you know that:

Rubies, sapphires and emeralds are all more rare than diamonds.

One to 3.5 billion years ago is when the majority of natural diamonds were formed. A handful has emerged from as deep as 800 kilometres, although most developed between 150 and 250 kilometres (93 and 155 mi) in the Earth’s mantle (500 mi).

Certain types of volcanoes can spit out diamonds.

Mauna Loa in Hawaii is the world’s largest active volcano and is 4,169m tall.

There are more than 1500 active volcanoes on Earth. Around 40–70 volcanoes erupt every year.

The majority of the volcanoes on Earth are not well-monitored or are not monitored at all.

Volcanic eruptions often create lightning occurring in their plume.

Catatumbo lightning occurs in Lake Maracaibo in Venezuela and means “House of Thunder” as it flashes up to 40 times per minute and up to 160 days a year.

Sprite lightning is a form of electric discharge that shoots upwards high above thunderstorm clouds.

Lightning creates radiowaves and some of them can escape to space.
