Ancient Volcanic Eruption In Java Island


The largest volcanic event of the last 300 million years may not have been triggered by a meteor, researchers now say. About 120 million years ago, as much as 1 percent of the Earth's surface may have been covered with volcanic eruptions. The origin of these massive 7-million-year-long eruptions in the Pacific Ocean, known as the Greater Ontong Java Event, has long been unclear, but some have suggested a cosmic impact as the trigger, smashing into the crust and causing lava to burst forth.

Amazon Fish


Arapaima, also known as “pirarucu” or “paiche,” are gigantic carnivorous fish that live in the Amazon and surrounding lakes. Encased in armored scales, they think nothing of living in piranha-infested waters—and they are pretty effective predators themselves, feeding on fish and the occasional bird. Arapaima tend to stay close to the surface, because they need to breathe surface air in addition to taking in oxygen through their gills, and make a distinctive coughing sound when they emerge for air. They can reach 2.7 meters (nine feet) in length and weigh up to 90 kilograms (200 lbs). These fish are so vicious that even their tongue has teeth.

Slovenian Alps


The Julian Alps (Slovene: Julijske Alpe, Italian: Alpi Giulie) are a mountain range of the Southern Limestone Alps that stretch from northeastern Italy to Slovenia, where they rise to 2,864 m at Mount Triglav, the highest peak in Slovenia and of the former Yugoslavia.A view of the Soča and the upper Sava river valleys spreads below Mount Triglav, Slovenia’s highest mountain. Lying between the two rivers is Triglav National Park, which protects numerous endemic animal and plant species in a region of high rocky mountains, deeply cut river gorges, high-mountain karst shafts, and attractive low mountains as well as the traditions of the once difficult life of mountain farmers and alpine dairymen.

Monarch butterfly


The monarch butterfly (Danaus plexippus) is a milkweed butterfly (subfamily Danainae) in the family Nymphalidae. It may be the most familiar North American butterfly. Its wings feature an easily recognizable orange and black pattern, with a wingspan of 8.9–10.2 cm.
Monarch butterflies are the most beautiful of all butterflies, some say, and are considered the “king” of the butterflies, hence the name “monarch”.

Appalachian Mountains


Appalachian Mountains , often called the Appalachians, are a system of mountains in eastern North America. The Appalachians first formed roughly 480 million years ago during the Ordovician Period and once reached elevations similar to those of the Alps and the Rocky Mountains before they were eroded.The Appalachian chain is a barrier to east-west travel as it forms a series of alternating ridgelines and valleys oriented in opposition to any road running east-west.
