Stacks
A stack is a geological landform consisting of a steep and often vertical column or columns of rock in the sea near a coast, isolated by erosion.
Dracaena draco
This tree is the natural symbol of the island of Tenerife. When the bark or leaves are cut they secrete a reddish resin, one of the sources of the substance known as Dragon's blood, used to stain wood, such as of Stradivarius violins.
Melo melo pearl
Melo melo pearls are extremely large and generally very round. One of the largest discovered is nearly the size of a golf ball.
Darvaza
The Derweze area is rich in natural gas. While drilling in 1971 geologists accidentally found an underground cavern filled with natural gas. The ground beneath the drilling rig collapsed, leaving a large hole with a diameter of about 50-100 meters. To avoid poisonous gas discharge, it was decided to burn the gas. Geologists had hoped the fire would go out in a few days but it has been burning ever since.
Giant kelp
Giant kelp is common along the coast of the eastern Pacific Ocean, from Baja California north to southeast Alaska, and is also found in the southern oceans near South America, South Africa, and Australia. Individual algae may grow to more than 45 metres long at a rate of as much as 61 cm per day.
McMurdo Dry Valleys
The McMurdo Dry Valleys are a row of valleys in Antarctica. The Dry Valleys are so named because of their extremely low humidity and their lack of snow or ice cover.
Wanfenglin
Wanfenglin consists of thousands of mounts in Guizhou, China.
Loreley
The Loreley is a rock on the eastern bank of the Rhine which soars some 120 meters above the water line. It marks the narrowest part of the river between Switzerland and the North Sea. A very strong current and rocks below the waterline have caused many boat accidents there.
