D. Composting Let's take a look at the various options and see if they make sense, given the context of the problem. A. Biological action * This option is rather vague and non-specific. It's a possible choice, but if there's something better, then choose it rather than this. Probable wrong choice. B. Carbon sequestration * This is the process of storing carbon long term to reduce the amount of CO2 in the atmosphere. Unless Ben has one heck of a lot of organic waste to get rid of, this is a rather silly option and therefore, wrong. C. Incineration * The key thing about the problem is "eco-friendly". Incineration will get rid of Ben's leftover food and organic waste, but in doing so will release carbon dioxide into the air and is likely to require some fuel in addition to the organic waste he wants to get rid of. So this too is a bad choice. D. Composting * This is the process of breaking down organic matter into compost that can be used as a soil enrichment treatment or fertilizer. The key thing to remember is that the material to be composted has to be organic. Doing this will allow Ben to have compost that he can use in the future on his garden. Overall, this is both an inexpensive and eco-friendly method for Ben to dispose of his leftover food and organic waste.

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports the evolution of earth due to chemical weathering.

hope it !

Answer from: Quest

in 1859, charles darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. he defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".
