Here it is. Fairly straightforward.

आपो वा इदम् अग्रे सलिलम् आसीत् / तेन प्रजापतिर् अश्राम्यत् // 

[All this was verily water, existing as the essence of water – the solidified cosmic egg. With that, prajApati (bhagavAn) exerted effort of thought on creation.]+

कथम् इदँ स्याद् इति / सो ऽपश्यत् पुष्करपर्णं तिष्ठत् /

[“How will this (Earth) come to be”, thus reflecting, he saw a lotus leaf, standing in the water. ]

सो ऽमन्यत /अस्ति वै तत् /यस्मिन्न् इदम् अधि तिष्ठति इति / 

[He considered, “There exists that (lotus leaf) in which this (Earth) is (staying)]

Engal Azhwan explains in Vishnu purANa commentary that the cosnic egg of the form of the lotus leaf - पुष्करपर्णं - was flooded+

स वराहो रूपं कृत्वा उप न्यमज्जत् / 

[He assumed the form of a boar and plunged (into the waters).]+

Engal Azhwan explains this as follows- पुश्कर पर्ण लिन्ग दर्शनात् ज्न्ऽआत्वा,  नारायण मूर्ते… यथा पुरा अकरोत् तथा वराह रूपं  – Seeing that lotus leaf, nArAyaNa decided, "I have to take avatAra, as I did previously as matysa etc."+

स प्र्̥थिवीम् अध आर्छत् /तस्या उपहत्य उदमज्जत् /तत् पुष्करपर्णे ऽप्रथयत् 

[He found bhU devI below. Moving near to her, he bore her (on his tusks) to the surface. He extended, ie, made that Earth variegated, in the cosmic egg of the form of a lotus leaf (on the causal waters).]+

उपहत्य - the root is gati. It means he approached near her. bhU devI was feeling dirty due to the waters of the panchabhUtAs and hiraNyAkSha's association.

To put her at ease, bhagavAn came to her as a boar, which is an animal that is unclean by nature and loves filth+

यद् अप्रथयत् /तत् प्र्̥थिव्यै प्र्̥थिवित्वम् / अभूद् वा इदम् इति / तद् भूम्यै भूमित्वम् 

[As he extended her, ie, made her variegated, that is the quality of “being variegated” of prithvI. This (Earth) came to be support of all. That is bhUmi's quality of “being the support"]+

The Earth which was undifferentiated like a mud ball, was made to bear rivers, trees, etc. by his sankalpa.

These are explained in the vishNu purANa shlokAs - समुद्धर भवायेश शं नो देह्य्+

तां दिशो ऽनु वातः समवहत् /ताँ शर्कराभिर् अद्र्ंहत्/ 

[bhagavAn who bears of fragrances like the wind (वात), carried her to all directions (ie, made her manifest in all directions). He made her firm, not causing her to shake or break further, with mountains made of gravel.]+

वातः is bhagavAn. As the wind bears fragrances, so does he. It means he purified her from her state of shyness and lack of cleanliness, and displayed her in full glory. शर्कराभिर् refers to mountains made of rocks, which arose on Earth by his sankalpa+

The various tattvAs like "waters", "lotus leaf" and so on are Yogic perceptions of the panchabhUtAs, Universe etc and shouldn't be misconstrued as clashing with scientific descriptions. This is the description of varAha in shruti.//
