Energy Distribution provides utilities, which are

Energy Distribution provides products for commercial consumption first. The most common media used to distribute energy are steam, air, hydronics and electricity. These form of media creates products such as the electric power that offer services and career advancement opportunities and Hydronics that delivers home and industries heating technology that give comfort to people and organizations.  

Moreover, the steam also provides products that is generated  from factories, mines, locomotives or trains and steamboats, which then eventually provides transportation, minerals, food and pharmaceuticals for commercial consumption.  

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 !
