Charles Darwin

Darwin’s theory (and, apparently, Wallace’s) would radically shift the study of evolution and our understanding of the world around us. Darwin began formulating his version of the theory in the late 1830s, according to his papers and correspondence.

James Hutton (1726–1797), a Scottish farmer and naturalist, is known as the founder of modern geology. He was a great observer of the world around him. More importantly, he made carefully reasoned geological arguments.

During the 1950s, Walter Karl Link was considered one of the world’s best oil exploration geologists, often compared to Wallace Pratt, John E. Brantley, Everette Lee DeGolyer, Lewis MacNaughton and A. I. Levorsen.

Rocks can grow taller and larger Rocks also grow bigger, heavier and stronger, but it takes a rock thousands or even millions of years to change. Water also contains dissolved metals, which can “precipitate” out of seawater or freshwater to grow rocks. These rocks are called concretions or nodules.

Rocks never die, they just change form. So they don’t have a lifespan. Rocks are always changing form, but too slowly to notice with you’re eyes. In fact; rocks aren’t even classified as living things.

Rocks themselves are not alive. But in a coral reef rock-like lime substance is continually produced from the skeletons of dead rock corals and the shells of mussels and other creatures which are bound together by sponges and calcareous algae.

Uluru

Uluru rises 348 metres above the surrounding plain. That’s higher than the Eiffel Tower in Paris, the Chrysler Building in New York or the Eureka Tower in Melbourne.

One of the rarest minerals in the world is Fingerite, only known to exist near the summit of the Izalco Volcano in El Salvador. This extremely rare mineral is a specific combination of vanadium and copper that require a very narrow range of environmental conditions to form.

Are Rubies More Expensive Than Diamonds? Although some rubies are incredibly valuable and can command very high prices, most rubies are considerably less expensive than diamonds of the same size. This lower pricing makes a ruby an appealing alternative to a diamond for an engagement ring or other jewelry.

The Most Expensive Gemstone in the World: The Blue Diamond

• Are worth $3.93 million per carat.
• Are rare to find in a flawless sample.
• Cause a huge stir in the jewelry industry when one goes to auction.

Scientists have calculated that wurtzite boron nitride and lonsdaleite (hexagonal diamond) both have greater indentation strengths than diamond. Source: English Wikipedia. (PhysOrg.com) — Currently, diamond is regarded to be the hardest known material in the world.

Diamond

Diamond is harder than obsidian, as obsidian is a form of volcanic glass. Obsidian has a hardness of 5 to 5.5 on the mineral hardness scale, whereas diamonds have a hardness of 10.
