Report Abuse. The tropical zone is characterised by strongly monsoonal weather patterns, distinct wet and dry periods which are highly reliable, large quantities of rain and high intensity rainfall, high temperatures, and high rates of energy transformation.
The neritc ocean zone is primarily in warm Tropical waters. This zone is the shallow region right before the continental shelf, since shallow allowing the sun to penetrate the water, causing the warmth. Since the climate is warm, many coral reefs exist on the shallow floor. The neritic zone is so sunny that another name for it is the Sunlit zone. 4) Soils and Geologic Characteristics The soil of the neritic zone is very rich, which causes for all the species to be able to live there. The richness of the soil depends on runoffs, waves, and currents to bring in the nutrients. The main geologic characteristic of the neritic zone is that it is low sea level which allows productivity to be high.
