The Earth's mountains, rocks and water bodies are ancient. Do you know how old they are?

Ming, an ocean quahog from the species Arctica islandica, was found on a seabed near Iceland by scientists in 2006. To determine its age, scientists counted the rings on its shell, similar to counting the rings in a tree trunk.

At 4,841 years old, Methuselah is one of two of the oldest known non-clonal trees on Earth. It's located in Inyo National Forest in the White Mountains of California, but the exact location is kept secret to protect the tree.

The zircon, which is one of the toughest materials on the planet, was found in Australia's Jack Hills range.

Apparently French women don't get fat and they also live to a ripe old age. Jeanne Calment (1875–1997) lived in Arles, France, for her entire life, even outliving a grandchild by several decades.

According to the University of California Museum of Paleontology, the cyanobacteria, which are aquatic and photosynthetic, are 3.5 billion years old — which is interesting, since the oldest rocks on Earth are only slightly older.

According to the National Parks Service, many scientists say the Appalachian Mountains in eastern North America are the oldest mountains on the planet, having formed roughly 480 million years ago.

A piece of crust in the Mediterranean Sea was recently determined to be as much as 340 million years old, which is impressive because most of the Earth's crust found in the ocean dates back only 200 million years. The Christian Science Monitor reports that researchers used magnetic sensing equipment to look through several miles of sediment on the floor of the Mediterranean to see the crust underneath.

Researchers analyzed gases dissolved in this ancient groundwater — including helium, neon, argon and xenonestimate — and dated the water to be 2 billion years old.

The lower jaw bone was found in the Afar region of Ethiopia and puts the first members of the human genus Homo there about half a million years earlier than previously thought, National Geographic reports.

Mount Etna is thought to be the world's oldest active volcano with eruptions dating back to at least 1500 B.C. Around 200 eruptions have been recorded, making it the most active volcano in Europe.

The Finke River, according to The Australian newspaper, dates back about 340 million years, even before the time of dinosaurs.
