JAJAJAJ no me gustan los koreanos pero el país que más predomina petróleo es Venezuela “El petróleo cumple una triple función en la sociedad: fuente de energía, materia prima y fuente de ingresos.”
Answer: Gneiss
Explanation: Gneiss is a metamorphic rock formed from shale at very high temperature and pressure condition. They exhibit a preferred alignment or orientation of platy minerals called foliation. They are coarse grained and exhibit gneissose banding. They are formed from highest grade regional metamorphism with temperature between 450 - 600 degree celcius and pressure between 800 - 1000 mega pascal. They generally occur in cores of fold mountain belts where mountain ranges have been eroded.
Answer:
Tundra ecosystems are treeless regions found in the Arctic and on the tops of mountains, where the climate is cold and windy, and rainfall is scant. Tundra lands are covered with snow for much of the year, but summer brings bursts of wildflowers.
Explanation:
Characteristics of the photic zone in the freshwater biome are the warmer water, light, rich in freshwater organisms, shallow.
The photic zone is the first zone from the top of the freshwater body of water. It is the shallowest part of the body of water, and it is further divided into the littoral zone and limnetic zone. This zone is the closest to the shore. The sunlight manages to penetrate in it, so it is a zone where the majority of the producers are able to survive and thrive because they can perform the process of photosynthesis. Since this zone enables the producers to thrive, and the producers are the basis of any ecosystem, it enables the further existence, high diversification, and thriving of all the other living organisms in the freshwater biome. The photic zone is also characterized with warmer water because it is on the top, it is heated by sunlight, so that provides nice conditions for the living organisms to be the most abundant in this zone.
