Geologic time can be difficult for people to understand. Our own lives are so short when we compare them to the age of the Earth, that the hundreds of millions of years of geologic time are almost too much to grasp. But for us to understand Earth activities today, we must have at least some basic...

Caves form through a variety of natural processes depending on their local geology and climate. Flowing lava, melting ice, dissolving rock, and crashing waves are the major processes that form these wondrous environments. In this activity, students will observe a model of how the most common type of...

"""""Soil porosity"""" refers to the amount of pore, or open space between soil particles. Pore spaces may be formed due to the movement of roots, worms, and insects; expanding gases trapped within these spaces by groundwater; and/or the dissolution of the soil parent material. Soil texture can also...

Human beings have been linked to earth materials since prehistoric times. They used caves for shelter, shaped rocks into stone implements, and later refined metals to make tools. Beyond practical purposes, Earth materials also were used to make pigments for paint. Rock walls became canvases where...

We usually think of caves forming as rocks are dissolved and the particles are washed away, leaving hollow spaces behind. This activity simulates the way that dissolution, a chemical weathering process, leads to the formation of caves. When precipitation such as rainwater or snowmelt mixes with...
