Explanation:

Concept maps work because they help people visually demonstrate relationships between ideas. This is particularly important when we are exploring a topic that is complex or that we are not very familiar with. Concept maps help us make these concepts clearer in our minds. They also allow us to better understand how one concept relates to others within the same subject.
