1.big bang Theory about the origin of the solar system that suggests our Sun and planets formed from a cloud of dust and gas.
2.steady state
Theory about the origin of the universe that suggests the universe is a never-ending cycle of expansion and contraction.
3.oscillating universe
Theory about the origin of the universe that suggests the universe has and will continue to be at a steady, continuous state.
4.nebular
Theory that upholds the big bang Theory but suggests there was an extremely rapid expansion or inflation milliseconds after the big bang.
5.inflation
Theory that suggests the origin of the universe started with an explosion and expansion of a very hot, dense, compact fireball.
6.condensation
Theory about the origin of the solar system that agrees with the nebular theory but stresses the importance of interstellar dust in planet formation.

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.
