ROCK DENSITY "Specific Gravity"
- Density is one of the most fundamental properties of geological materials. Density is helpful in identification of rocks and minerals. Density is defined as mass per unit volume (ie. grams / cubic centimeter). What you are actually measuring is specific gravity. Specific gravity is a dimensionless number (no units), and is the ratio of the weight of a rock to the weight of an equal volume of water. For our lab purposes, there is no difference between the two.
THREE DIMENSIONAL MODELING OF A LAND AREA
- In this project, you will construct a three dimensional model of an area of land, from a quadrangle map. You can obtain quadrangle maps from the United States Geological Survey, or from a map store. Choose a map of your area so you can compare your model to the actual land area. Lines of equal altitude are drawn on the map.
