Question

the aerial images show how part of a brazilian rain forest changed over a 14-year period.
1992 2006
the light colored areas on the 2006 map show where humans have cut or burned the forest to make space for farms.
which three effects will this management practice likely have on the area?
a. reduced biodiversity
b. increase in storm water runoff
c. long term increase in soil productivity
d. decreased availability of mineral resources
e. short term increase in carbon dioxide emissions

Explanation:

• Option A: Deforestation destroys habitats, so species lose homes, leading to reduced biodiversity.
• Option B: Trees absorb and retain water; without them, storm water runoff increases as there's less interception and absorption.
• Option C: Deforestation and farming (especially with burning) deplete soil nutrients long - term, so soil productivity doesn't increase long - term.
• Option D: Deforestation is about vegetation/land use, not mineral resources, so this is irrelevant.
• Option E: Burning forests releases stored carbon as CO₂, causing a short - term increase in CO₂ emissions.

Answer:

A. reduced biodiversity, B. increase in storm water runoff, E. short - term increase in carbon dioxide emissions
