Explain how the wind may be involved in the formation of sandstone arches.
WITCHER [35]

Answer

Wind may be involved in the formation of sandstone arches by facilitating erosion which wore away exposed sections of rocks and enlarges the cracks on the surface forming marrow sandstone fins.

Explanation

Sandstone arches can be formed when a large piece of sandstone flaked off as a result of high winds. In addition to that, alternative frost and thawing can result into crumbling of porous sandstone which will in the long run cut through some fins. These resulting holes enlarge to form arches with effects of weathering and rock fall caused by wind.

Porque los alimentos se oscurecen?(platanos, palta, manzana, papa, etc) respondan pls✋
inn [45]

Answer:

Una enzima es una sustancia, generalmente una proteína, en la célula de un organismo que acelera las reacciones químicas.

Durante el pardeamiento enzimático, una enzima llamada fenolasa y otro compuesto orgánico que se encuentra en las células de la fruta llamados fenoles pasan por una reacción de oxidación cuando se exponen al oxígeno. La fenolasa regula la reacción, convirtiendo los fenoles en melanina.

Por lo general, las enzimas de la fruta están encerradas en tejido. Las enzimas están metidas en sus células, trabajando para madurar la fruta. Pero cuando esas células se descomponen, ya sea por una causa externa como si alguien muerde o corta la fruta o por causas naturales como el envejecimiento, las enzimas se liberan y entran en contacto con el oxígeno, lo que desencadena la reacción química y hace que la fruta se vuelva marrón.
