Interesting Facts about Volcanoes
Volcanoes are openings in the Earth’s surface. When they are active they can let ash, gas and hot magma escape in sometimes violent and spectacular eruptions. The word volcano originally comes from the name of the Roman god of fire, Vulcan. Volcanoes are usually located where tectonic plates meet.
How many oceans are there?
While there is only one global ocean, the vast body of water that covers 71 percent of the Earth is geographically divided into distinct named regions. The boundaries between these regions have evolved over time for a variety of historical, cultural, geographical, and scientific reasons. Historically, there are four named oceans: the Atlantic, Pacific, Indian, and Arctic. However, most countries - including the United States - now recognize the Southern (Antarctic) as the fifth ocean. The Southern Ocean is the 'newest' named ocean.
Volcano Facts
6. Volcanoes are classified as active, dormant or extinct depending on the amount of volcanic activity happening. 'Active' means there's regular activity, 'dormant' means there's been recent activity but that it's currently quiet and 'extinct', meaning it's been so long since the last eruption that it's unlikely to ever erupt again. 7. 8. 9. 10. 11.

The oceans of Earth serve many functions, especially affecting the weather and temperature. The Earth's oceans are all connected to one another. There are also many seas (smaller branches of an ocean); seas are often partly enclosed by land.

Quick Facts on Icebergs | National Snow and Ice Data Center
Icebergs are commonly found near Antarctica and in the North Atlantic Ocean near Greenland. What is an iceberg? Icebergs are pieces of ice that formed on land and float in an ocean or lake. How do icebergs form, and where do they go? Icebergs form when chunks of ice calve, or break off, from glaciers, ice shelves, or a larger iceberg. When an iceberg reaches warm waters, the new climate attacks it from all sides. Icebergs can develop into a variety of shapes as they break apart. Why are icebergs important? Icebergs pose a danger to ships traversing the North Atlantic and the waters around Antarctica. The International Ice Patrol uses airplanes and radars to track icebergs that float into major shipping lanes. Icebergs can also serve as tools for scientists, who study them to learn more about climate and ocean processes. Scientists test their equipment on a small iceberg during the 2006 IceTrek expedition.
