The tropical oceans on earth lie in an equatorial band between the Tropic of Capricorn and Tropic of Cancer. Tropical water oceans comprise of the center of the Atlantic and Pacific oceans and nearly all of the Indian Ocean. The…

In the world of geology, the term “shearing” describes a distinct motion of two rock surfaces against each other. It is most often caused by intense pressure under the earth’s crust. Description Shearing can be described as the lateral movement…

The Celsius scale, created in the mid-18th century, is part of the metric system, and is today the most common form of temperature measurement. Because of the near-universal adoption of the metric scale, Celsius is the official form of temperature…

If you have a volleyball in your garage, you have the makings of an interesting science fair project. Volleyballs are useful components of models — paint one orange and use it as the sun in a replica of the solar…

After your third papier-mâché volcano or soda bottle rocket, it may be time to liven up your science fair with a creative project that examines the powders, gels and creams that line your medicine cabinets. Cosmetics are common household items…

Forest biomes are regions of the world dominated by trees. It is estimated that forests cover approximately one-third of the Earth’s land. Forest biomes are divided into three broad categories: temperate, tropical and boreal forests. Environmental factors such as climate,…

The spinning of a disk on a shaft often translates to linear motion. The most obvious example is an automobile wheel, but forward motion can also be important when designing gear and belt systems. The translation from rotation to linear…

Volcanologists classify a volcano’s eruptions by its type and qualitative standards, as each volcano type behaves differently. Geologists categorize volcanoes into three major groups: shield cone, cinder cone and composite cone, also known as stratovolcanoes, which represent 60 percent of…

Earth is split along two lines — the Equator running east-west and the Prime Meridian running north-south — into hemispheres. While each hemisphere, as these quarters of the earth are called, is distinct from its peers, the north-south division caused…

Altitude and latitude are two primary factors known to affect the temperature variations on Earth’s surface because varying altitude and latitude create unequal heating of Earth’s atmosphere. Latitude refers to the distance of a location on Earth’s surface from the…
