What determines how explosive a volcanic eruption will be
By: Rex Trulove
Volcanoes have been producing new land mass for millions of years. However, they can also be extremely destructive. It isn't unusual for people to wonder what determines how explosive a volcanic eruption will be. There is an answer to the question, which lies in the...

Since the formation of the earth around 4.5 billion years ago, it's climate has undergone vast changes due to the constant evolution of its physical elements like its landmasses (continents) and oceans, changes in the levels of greenhouse gases contained within its dense atmosphere...

Swamp gas or marsh gas has been known by many names throughout the ages. The fascination was not with the gas but with the lights they produced. Travellers, campers and hunters generated innumerable stories over the eerie burning light often seen over swamps. English folklore...
The laws of thermodynamics
By: Nigel Holmes
Thermodynamics is the science of how heat, and more broadly, energy, flows. The Laws of Thermodynamics are universal principles that explain how these flows work, much as Newton’s Laws of Motion describes how physical objects move. For a more detailed explanation, take a look...
Predictions on global warming and relocation problems of humans
By: Christyl Rivers
Relocation problems related to global warming are already happening. Every where, even before the current warming, people have historically fought over resources when ever one side has less access to water, fuel, food, medicine and more. Africa has several conflicts currently raging over resources. In...
What causes a geyser
By: Rex Trulove
A geyser is a vent in rock that periodically puts forth a blast of super-heated water and steam. It is likely that most people already know this. However, the cause of the jet of hot water that makes up a geyser eruption may be a...
Marine survey discovers brainless fish
By: Laurie Childree
Marine surveys discovered fifteen rare species of fish during 2011, one of which was faceless and brainless. In the waters of Orkney off Tankerness the prehistoric Amphioxus was found. It is representative of the early evolution of the backbone with the nerve chord that runs...

The study of energy is called thermodynamics. Thermodynamics describes how different forms of energy relate to each other and how they interconvert. Energy exists as several forms, such as heat, sound etc. Thermodynamics describe how these forms of energy behave in a thermodynamic system. There...
By: Blaise Pascal
The laws of thermodynamics stem from the study of work, energy, energy transfer, and the relationship between them. Initial work with these theories began in the late 18th century but gained prominence in the 19th century as people sought more efficient machines and engines. Ultimately...
