Big Ideas Review
Unit 1: Thinking Geographically
Topic 1.1: Types of Maps
- Reference Maps
- Thematic Maps
- Cartogram: A map that distorts land areas to show changes in a particular value.
- Choropleth Map: Uses different colors/shades to represent changes in a value.
- Dot Map: Uses dots to represent values; more dots indicate higher values.
- Graduated Symbol Map: The size of symbols represents value; larger symbols indicate higher values.
- Isoline Map: Connects areas sharing a particular value with lines.Topic 1.1: Spatial Patterns
- Definitions related to space and arrangement:
- Absolute Distance: Measured in standard units (e.g., 5.9 miles).
- Absolute Direction: Utilizes cardinal points (North, South, East, West).
- Relative Distance: Implies an estimation, not using standard units (e.g., 25 minutes to a destination).
- Relative Direction: Describes direction in imprecise terms (e.g., left/right).
- Clustering: Grouping of similar items/people (e.g., students grouped by scores).
