  1. THE STORY OF MINERALS This is the story of how minerals formed in our universe, which began over 13 billion years ago with a burst of energy, then a cooling, then gravity takes over and we get stars. Stars are the beginning of our story of how the elements formed. Elements are the chemical composition of minerals. Supernova explosion

  2. Eventually a few of those stars blow up — that's how some stars die — and in a blaze of intense heat, we get the first 12 or so minerals: atoms forged by starbursts. Carbon, nitrogen, silicon, iron all come from stars. Dr. Hazen says the universe's original minerals include (and this is kind of cool) diamonds, as in Lucy in the Sky With… teeny bits of diamond dust floating in deep space. Then gravity keeps on pulling dust together, forming asteroids. Those asteroids collide, baby planets form, then bigger planets, then planets with volcanoes and planets with plate tectonics that pull rocks on the surface down under, melting them, freezing them. Then water appears and trillions of drips later, rocks have water molecules locked inside them and if you stop there, 10 billion years after creation, and count all the minerals that have evolved, the number has grown from the original 12 to about 1,500. That's 1,500 different ways to organize atoms into topaz and feldspar and clay and iron and all those words that end in "ite." Not a bad number, 1,500. At more than 3 billion years old, this formation is one of the oldest rocks on the planet./ Now comes the surprise. About 3.5 billion years ago, here on our planet, life began. No one knows how, people argue about why, but one would think the presence of life would be a ho-hum for the minerals. They're rocks. What do they care? But life is a great sculptor. One very early form of pond scum figured out how to exhale oxygen into the air, and soon (well, not THAT soon, but soon enough) our atmosphere had enough oxygen to create rust, to combine with organic chemicals to make creatures with shells and bones and those creatures died and became rocks. What is coral but a clump of dead skeletons? Look at the White Cliffs of Dover — that's a heap of dead plankton.

Eventually a few of those stars blew up — that's how some stars die — and in a blaze of intense heat, we got the first 12 or so minerals: atoms formed by starbursts known as supernovas. Carbon, nitrogen, silicon, iron all came from the stars. The universe's original minerals include diamonds, as in “Lucy in the Sky With Diamonds”… teeny bits of diamond dust floating in deep space. Then gravity kept pulling the stardust together, forming asteroids. Those asteroids collided, and baby planets formed, then bigger planets, then planets with volcanoes and planets with plate tectonics that pull rocks on the surface down under, melting them, and freezing them. Then water appeared and trillions of drips later, rocks had water molecules locked up inside them. Approximately 10 billion years after the planet’s formation, all the minerals had evolved. The number grew from the original 12 to over 1,500 different types of minerals. Over 4.5 billion years later, our planet is filled with rocks (3 different types); with many different colors and structures. It is part of what makes our world so beautiful. Our planet is the third “rock” from the Sun.

This type of rock is found on the ocean floor, where life first began. At more than 3 billion years old, this formation is one of the oldest rocks on the planet. Now comes the surprise. About 3.5 billion years ago, here on our planet, life began. Soon after, our atmosphere had enough oxygen to create rust, to combine with organic chemicals to make creatures with seashells and bones and those creatures died and became rocks. What is sea coral but a clump of dead skeletons? Coral forms rocks. Look at the White Cliffs of Dover in England — that's a whole lot of dead seashells.

  5. The famous White Cliffs of Dover (England) These cliffs are made of chalk. Chalk is formed from the compaction and cementation of microscopic seashells.

  6. Life is so unique. It created plants with roots that can rip rocks apart (slowly, but gradually that's what they do) and worms that can ingest rocks and break them into soil. That is called weathering. So let's step back and ask, how many new minerals have been created by living things on Earth? Remember we started with 1,500 minerals before life. After life, the number jumps to over 4,500. Life creates rocks! Whoa! We all know that living things need minerals. When you eat a raisin, you are putting iron in your blood. We drink milk to put calcium in our bones. So we need minerals. What most people don’t know is that minerals, in some sense, need us. The presence of life on Earth increased the number of rocks on Earth. The Himalaya mountain range began taking shape around 60 million years ago. Home to the world's highest peaks, including Mount Everest, these mountains are made from deep water marine shale consisting of gneiss, slate and sand stone.

  7. Called "Crazy Lace", this agate rock found in Mexico has the mineral quartz infused with iron and aluminum.

  8. The "Wave," found in Arizona, is a small ravine of eroding sandstone rock domes.

  9. In the middle of Egypt's White Desert, stand massive chalk rock structures created by sandstorms.

  10. Stalagmites and stalactites found in Virginia's Luray limestone caverns formed millions of years ago. Stalactites hang down from the ceiling of the cave; stalagmites stick up from the floor of the cave.
