-Stage 3-

Maps

 

Knowing how to read a map is one of the most important tools a geologist can have. Maps portray a lot of information in a very small amount of space, making them vital to understanding the history of the landscape. There are many different types of maps and there is a lot of information that they can contain. I am only going to focus on some of that information through the following four sections. There are four main Map Sections and the knowledge builds upon itself as you move through each of the sections.

 

 

 

Map basics includes a lot on the information that is needed first to read and understand a map.

 

 

 

Topographic maps illustrate 3 dimensions on a 2-dimensional surface. This sections help a person to be able to understand and extract information from them.

 

 

 

Geological maps take a topographic map and add another layer of information, which is the underlying geology of the region.

 

 

 

The last section, stratigraphy, is not strictly map based but is associated enough with geological maps to fit in here. Stratigraphy looks at the Structures found within the Earth and combines them with the Geological maps to be able to begin to piece the history of a set of rocks together.
