Explanation:

Acha chalta hoon

Duaaon mein yaad rakhna

Mere zikr ka zubaan pe swaad rakhna (x2)

Dil ke sandookon mein

Mere ache kaam rakhna

Chitthi taaron mein bhi

Mera tu salaam rakhna

Andhera tera maine le liya

Mera ujla sitaara tere naam kiya

Channa mereya mereya

Channa mereya mereya

Channa mereya mereya beliya

O piya.. (x2)

Mm.. mehfil me teri hum naa rahe jo

Gham toh nahi hai, gham toh nahi hai

Qisse humare nazdeekiyon ke

Kam to nahi hai, kam to nahi hai

Kitni dafaa subah ko meri

Tere aangan mein baithe maine shaam kiya

Channa mereya mereya

Channa mereya mereya

Channa mereya mereya beliya

O piya.. (x2)

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.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
