Which of these is NOT an impact of acid rain?

Acid rain's impact includes soil acidification, building deterioration, and crop loss. It does not improve the taste of water; it actually makes it more acidic.

How are the atmosphere, hydrosphere, and lithosphere connected?

The atmosphere, hydrosphere, and lithosphere are interconnected as they interact and influence each other. For example, the atmosphere provides water vapor to the hydrosphere, which in turn affects weather patterns and influences the lithosphere.

What is the greenhouse effect?

The greenhouse effect is the process where certain gases in the atmosphere trap heat from the sun, keeping Earth warm enough to support life. These gases, such as carbon dioxide and methane, act like a blanket, preventing excess heat from escaping into space.
