Question

the burning of fossil fuels by humans primarily affects the geosphere and has little impact on the atmosphere. * 1 point
true
false

deforestation, the clearing of forests, only impacts the biosphere and has no significant effect on other spheres. * 1 point
false
true

acid rain, caused by pollutants in the atmosphere, can negatively impact both the hydrosphere and the geosphere. * 1 point
false
true

Explanation:

1. Burning fossil fuels releases large - amounts of carbon dioxide and other pollutants into the atmosphere, so it has a major impact on the atmosphere, not little.
2. Deforestation affects the biosphere, but also impacts the atmosphere (less carbon - dioxide absorption), hydrosphere (changes in water cycle), and geosphere (soil erosion). So the statement that it only impacts the biosphere is false.
3. Acid rain, formed from atmospheric pollutants, can contaminate water bodies (hydrosphere) and weather rocks and soil (geosphere), so it can negatively impact both.

Answer:

1. False
2. False
3. True
