Under what conditions does natural selection occur?​

There are 4 condition:

1. Heredity

2. Reproduction

3,. Fitness or organism

4. Variation in individual characters among population

Variation and inheritance, heredity, and individual characteristics.

Explanation:

These factors are necessary for natural selection to occur, because otherwise if you don't have them it won't be able to happen.

volcanoes (an event in the geosphere) release a large amount of particulate matter into the atmosphere. these particles serve as nuclei for the formation of water droplets (hydrosphere). rainfall (hydrosphere) often increases following an eruption, stimulating plant growth (biosphere).

the answer is: reproductively
