Question

reading geographically. read the passage. the amazon rain - forest covers about 2.3 million square miles in the northern half of south america. most of the rain - forest is in brazil, but it also stretches across several other countries. the amazon river descends from its main source in the andes mountains and flows eastward to empty into the atlantic ocean. over time, farming and other development has led to deforestation in the amazon. scientists estimate that more than 277,000 square miles of forest have been lost since 1970. at which scale would satellite images be most useful for studying changes in the rain - forests land area? local; regional; global; national

Explanation:

A regional - scale satellite image would provide detailed enough information to study changes in the rainforest's land area. Local - scale would be too small and may not cover enough of the rainforest, global - scale would be too broad and lack the necessary detail, and national - scale may not be the most appropriate as the Amazon rainforest spans multiple countries.

Answer:

regional
