Scale Affects Change Practice Test

Two spatial-scale representations show a volcanic landscape:

• Representation 1 (close-up, local scale): A field sketch of a 10 m wide area shows fresh lava covering plants and forming a rough surface. • Representation 2 (large-area, larger spatial scale): A map of a 50 km wide region shows the lava flow covers a thin line compared to the size of the whole island.

Which statement is supported at the close-up scale but not necessarily at the large-area scale?

Two time-scale representations show vegetation recovery after a wildfire:

• Representation 1 (short-term): Weekly drone images for 2 months show the burned area staying mostly black with only a few small green patches. • Representation 2 (long-term): Satellite images taken once per year for 10 years show the burned area gradually becoming greener and more similar to surrounding forest.

How does the conclusion change when moving from the short-term to the long-term time scale?
