Earth’s landscape can change over time. What can happen to a watershed as a result? Explain your response in your own words and include terms from the lesson.
" If glass is lacking, basalt disintegrates mainly into silts and clays by separation of crystals as weathering progresses. Such basalts do not contribute much to the mainly sand-size fluvial sediment. In fluvial sand, the modal percentages of augite, olivine, and basalt fragments vary greatly in comparison to the percentages of phenocrysts in the source basalt: coarse fluvial sands are depleted in augite and olivine and enriched in basalt fragments. Fine-medium fluvial sands are enriched in augite and olivine and depleted in basalt fragments." http://jsedres.geoscienceworld.org/content/64/3a/490.abstract Basically weathering and overtime becomes depleted.
Weathering; give your teacher this answer and it will stand out completely of its description modestly
thank you so much yo <3
