Are my answers right

OMG answer the question i have gone all over this site and all i got were confusing conversations :,(

no offense to you guys, you seem nice :)

Sorry my answers are

1. B
2. A
3.D
Are they right?

I don't agree with 1 and 2. You didn't answer 3.

3 is ok.

! and 2 are ok now.

1. The correct answer is A. Acid rain. You are correct.

To determine this answer, you need to have knowledge about car and truck emissions and their impact on the environment. Acid rain is caused by pollutants like sulfur dioxide and nitrogen oxides, which are primarily released from industrial processes and power plants, rather than car and truck emissions.

2. The correct answer is C. Air. You are correct.

When trying to determine pollution, it can be more challenging to assess air pollution compared to other places like aquifers, streams, or ponds. Air pollution is invisible, and its source might be distant or widespread, making it more challenging to identify and quantify.

3. The correct answer is D. Selective cutting. You are correct.

Selective cutting involves carefully selecting and cutting down specific trees while leaving others standing. This method aims to achieve sustainable forestry practices and maintain the overall health of the forest. Clear-cutting, on the other hand, involves removing all or nearly all trees from an area, and contour farming refers to the practice of plowing across the slope of the land to prevent erosion. Desertification refers to the process of fertile land becoming desert-like.

Overall, your answers are correct! Well done.
