Long before mankind developed sophisticated technology like satellites to forecast the weather, people had to depend on simpler methods such as the barometer. This instrument detects and measures changes in the atmosphere that vary when the weather is about to change. These measurable changes can...
Evolution of Earth's atmosphere
By: Jon Dainty Sr.
The Earth’s atmosphere formed following the initial coalescence of the Earth-Moon system, estimated to be 4.5 billion years ago. It would be unthinkable for most present-day organisms to attempt to live in that environment. The primary component of the atmosphere was carbon dioxide...

Given the right conditions, snow on any slope can become unstable and suddenly flow down the slope with devastating affects. This phenomenon is known as an avalanche. While there are a variety of factors that can lead to an avalanche, it is usually caused by...

Over the course of the over four and a half billion years since the earth began forming, it has gone through many changes. One of the most important developments was the atmosphere that supports life on this planet. There are many theories as to how...

The Aurora Borealis is the name given to the extraordinary display of lights in the atmosphere near the Arctic Circle. Also called the “Northern Lights,” the Aurora Borealis form spectacular colors and clouds shapes that appear to dance and move in the sky...
How avalanches are triggered
By: N. Owen Holme
An avalanche is a layer of snow that flows down a mountain slope. Only three things are required for an avalanche: a slope between 25 and 65 degrees, a layer of snow with a weak layer beneath and a trigger. The potential for loss of...

For many people, winter storms mean snow and frigid temperatures. Even still, for a few people it is a mad rush to the grocery store for milk, eggs, bread, and whatever else they feel they need to stock up on. However, do you really know...
What it means when a barometer is rising or falling
By: Steven Mars
A barometer is a meteorological instrument that measures atmospheric pressure. Meteorologists (scientists who study the weather) use barometers to predict changes in the weather using the fact that a change in air pressure is a change in weather. A rising barometer is usually an indication...

The Great Blizzard of 1993 was a large cyclonic storm that occurred from March 11 to March 15 on the East Coast of North America. It was distinguished from other storms due to its intensity, size, and wide reaching effect. The storm's main impact was...
Facts about ball lightning
By: Mac Pike
It is more than a little bit tricky to set forth a definitive list of facts about ball lightning, because there are relatively few hard facts that anyone agrees on. The very existence of ball lightning is not universally accepted by the scientific community. It...
