As we move across the periodic table of elements, certain trends are evident. The placement of individual elements in the periodic table allows us to predict many characteristics of elements such as state of matter at room temperature, reactivity, and
valence electrons just to name a few. As one moves from left to right across the periodic table, what trends are evident?
A)
Atomic radius increases moving left to right.
B)
Nonmetallic character increases moving left to right
Electron affinity increases across the periodic table.
D)
Elements change from solids to liquids and then gases.
E)
Most reactive elements on left and least reactive on right.

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 !
