Earth Map Forecasts at the Cranberry Farm

A Display in the Harvest Office

The cranberry farm is preparing its harvest office for visiting families. Beside the harvest calendar, the workers are building a display about Earth's features. The display uses two simplified maps of imaginary land regions. Their mountain, volcano, and earthquake locations were chosen to model patterns found on Earth. Visitors will study the maps and write prediction cards. A useful card tells what might be found and gives evidence from the map.

Read each location as a pair of numbers: east first, then north. For example, (2, 5) means 2 on the east axis and 5 on the north axis. North is toward the top of both maps. East is toward the right. The maps do not show coastlines, roads, or distances. Each dot has a name, such as A1. Find that name in the feature list below its map. M marks a mountain location. V marks a volcano location. E marks a location where an earthquake was recorded during the study period. Letters together describe the same location. For example, ME means a mountain and a recorded earthquake, but no mapped volcano.

A question mark in a feature list identifies a location that has not yet been checked. Other unmarked grid locations have no feature recorded in this display. That does not tell us what might happen there in the future. The earthquake records cover the same study period in both regions. They show where earthquakes were recorded, not when the next earthquake will happen. Compare groups of locations, notice exceptions, and use words such as likely or might when making predictions.
