Lesson Check: ving Continents
The map shows where qlaciers existed 250 million years ago
B) mwa
Which explanation is supported by the data in the map
Glaciers formed in the locations shown on the map because of a change in climate that caused the southem hemisphere to experience an ice age
Rationale: There is no evidence of an ice age occurring within only one hemisphere. In addition. there is no information on the map to support this explanation
Glaciers at one time covered most of the continents in the world. but the glaciers melted and the areas on the map are places where glaciers still remain
Rationale: The areas shown in the map are too warm for continental glaciers to form today. In addition, the map does not provide evidence of worldwide glacial coverage followed by extensive melting to only those locations
There is evidence Of glaciers in the areas identified on the map because the current climate in those areas still supports glacier formation
Rationale: The areas shown in the map are too warm for continental glaciers to form today
There is evidence Of glaciers in the areas identified on the map because the C) D) continents were once located near a polar region, but then over time the continents moved apart
Rationale: The shape Of the continents and the glacial evidence supports the theory that those locations were all joined together at one time and then moved apart to the current locations. In addition. though not shown on the map. those areas were part of the single landmass called Pangaea. and were located in the extreme south near Antarctica. where they experienced very cold conditions
Correct Answer
D) There is evidence of glaciers in the areas identified on the map because the continents were once located near a polar region. but then over time the continents moved apart
