What are two different uses for a geological map of an area?
4. India sits across the equator, and is currently considered tropical in many areas. Even low elevation areas show evidence of large ice sheets having once covered most of India. This evidence, (glacial scratching, deposits, and u-shaped valleys), does not make sense for such a warm area. The pattern of the glacial evidence also does not make sense for India in its present position. It does make sense, however, if India is part of Pangaea, and is moved to its position 200 million years ago, much further south, towards the pole. 5. Geologists will look for evidence on the surface that reveals what is going on underneath. For example, a steep, flat-sided cliff may suggest a deep fault. A small area of rock that stands out from the rock around it may indicate igneous rock that cooled underground, solidified, then had the rock layers above it removed (through erosion). A hilly area may indicate the presence of magma deep underground causing the surface to buckle. Rounded hills may indicat
