What balances are affected by the local force of gravity

I think its earth and the air i think its air because we only have a little bit of gravity that's how we throw our baskets in the air to celebrate and it's a force it forces us by staying on land that way to don't go up on the sky i also said earth too because earth continues moving in circles like earth is moving right now I meant that we can't feel it moving but it moves there is a water thing that gives us water its basically a planet that idk but it gives us water to provide  water for us to drink and use it for lakes and rivers i hope that this helps

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 !
