Eolian features

Planets with atmospheres show the effects of eolian or wind processes. Wind transports material from one location to another and causes both deposition and erosion. The physics of fluid dynamics is applied to material being transported by the wind (Greeley and Iverson, 1985). Larger material is transported by traction, the rolling of material along the surface. Slightly smaller material can bounce along the surface, a process called saltation. Pebbles are sometimes moved by impact creep, where saltating grains impart momentum through their impact on the pebble. The smallest material is carried within the wind flow by suspension. Depending on the wind speed and thickness of a planet's atmosphere, suspension typically operates on particles <60 ^m in diameter (dust), saltation efficiently moves material in the

Renewable Energy 101

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable. The usage of renewable energy sources is very important when considering the sustainability of the existing energy usage of the world. While there is currently an abundance of non-renewable energy sources, such as nuclear fuels, these energy sources are depleting. In addition to being a non-renewable supply, the non-renewable energy sources release emissions into the air, which has an adverse effect on the environment.
