"The period during which fertilisation is more likely to take place is called the fertile period," What is meant by the term fertilisation?
please help mee i need this answer for hw;-;

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).

i'd have to say the answer is probable the second option "the geosphere interacting with the atmosphere"
