What were the origins of agriculture? There are few wild plants consumed widely anymore, especially in the developed countries. Most of the plants we eat as fruits, vegetables, and grains:

do not occur in the wild, but have been developed exclusively by humans through selection and domestication

Explanation:

Most of the plants that we eat today were developed by humans through the process of domestication and artificial selection.

Artificial selection is the process by which selective species are intentionally bred which leads to the formation of new species and this leads to ultimately the domestication of these organisms.

The domestication and selection of plants took place more than 5000 years ago.

Therefore, most of the fruits, vegetables and grains that we consume today are produced by artificial selection and breeding.

mountains can affect the climate of nearby lands. in some areas, mountains block rain, so that one side of a mountain range may be rainy and the other side may be a desert. much of airborne moisture falls as rain on the windward side of mountains.

explanation:

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 !
