Explanation:

Question 26

The process where condensed water in clouds falls to Earth's surface is precipitation. Evaporation is liquid to gas, condensation is gas to liquid, and sublimation is solid to gas (or vice versa) without liquid phase. So the correct option is d.

Invasive species often have higher reproductive rates than native species, lack natural population controls (like predators in the new environment), and can evolve/adapt quickly. They aren't always stronger than natives. So the biggest problem is a.

Renewable energy sources (like solar, wind) have lower carbon emissions (a), their supply is replenished/renewed (b), and they produce fewer pollutants (c). So all the above (d) is correct.

Answer:

d. Precipitation
