I'm completing an assignment for Earth-Space Science and have come across a word that I do not know, it does not come up in the dictionary and is quite specific to geology. The word is struetural, and was used in the sentence "The rock making up the above—mentioned peak—forest is quartzose sandstone of the Late Devonian platform struetural layer." Also the article is "GEOTECTONIC CONDITIONS OF FORMATION OF THE WULINGYUAN PEAK- FOREST LANDFORM, CHINA" if that helps. If anyone can find this word used in any other article or give me any source that hints at its definition that would be greatly appreciated.

Simulating adaptations in a species in this activity, you will discuss in detail the adaptations in a species of rain forest plants. you will build a simulation that explains the changes in the traits of the plant population over 10 years. you will also establish a scientific explanation to justify the changes in the traits of the population, * time to complete: 1-2 hours part a an organism's adaptations are specific to its native environment. an organism that lives in a coniferous forest will have different adaptations compared to an animal that lives in a tropical rain forest. the following graphs show the temperature and precipitation throughout the year for two different forests: a coniferous forest in canada, and a tropical rain forest in belize. evaluate the graphs, and then explain why plants from these two ecosystems will have different adaptations. in your answer, explain the survival challenges that plants face in these two environments.
