The Earth was raised from Water.
The creation process.:
As, Taittiriya 2.1.1. says.:
तस्माद्वा एतस्मादात्मन आकाशः सम्भूतः । आकाशाद्वायुः । वायोरग्निः । अग्नेरापः । अद्भ्यः पृथिवी ।
From That, verily,—from This Self (Atman)—is ākāśa (ether) born; from ākāśa, the air; from the air, fire; from fire, water; from water, earth;.
Again, Srimad Devi Bhagwatam Says.:
Dharmarāja said :-...By Whose command the wind supports the water; the water supports the tortoise; the tortoise supports the Ananta and the Ananta supports the earth; the earth supports the oceans, mountain and all the jewels. The earth is of the nature of forgiveness, i.e., endures all. For this reason all things, moving and non-moving, rest on Her and again melt away in Her...(Srimad Devi Bhagwatam Maha Puranam 9:38:7-79).
So, from, Atman (Self) comes Akasa (Sky/Space), from space comes wind, from wind comes fire, from fire comes water, from water comes earth and again from earth comes mountains, oceans, jewels, etc, etc, etc.
To elaborate it even more.:
1. From Bhagawan Sakshat Nirguna Para Shiva (Adho-Mukha/Atman/Mokshātita), comes Saguna Bhagawan Sada Shiva (Ishana/Param-Purusha/Akasha/Moksha),
2. from Sada Shiva, comes Ishwara (Tat-Purusha/Prakriti/Wind/Maya),
3. from Ishwara, comes Rudra (Aghora/Intellect/Fire/Regeneration),
4. from Rudra, comes Vishnu (Vāmadeva/Water/Preserva/Ego),
5. from Vishnu, comes Brahma (Sadyojāta/Mind/Earth/Creation) and
6. from Brahma, starts the Secondary creation.
"yo vedaadau svaraH prokto vedaante cha pratishhThitaH | tasya prakR^itiliinasya yaH paraH sa maheshvaraH " (Taittiriya Aranyaka 10.12.3.17)
"It is Lord Maheshwara who transcends the syllable Om which is uttered at the commencement of the recital of the Vedas, which is well established in the vEdAnta (Upanishads) and which is dissolved in the primal cause during contemplation".
"kaa.nsyaghaNTaaninaadastu yathaa liiyati shaantaye | o~Nkaarastu tathaa yojyaH shaantaye sarvamichchhataa | yasminviliiyate shabdastatparaM brahma giiyate | dhiya.n hi liiyate brahma so.amR^itatvaaya kalpate |" (Brahmavidya Upanishad 12-13).
"And just as the sound of a metal utensil – or of a gong dies in silence – so he, who seeks the All lets the OM sound fade away in silence. For that wherein the sound fades away is the Brahman, the higher. Yea, the whole sound is Brahman and conduces to immortality”.
“nama stArAya cha” Yajurveda (IV:5:8:h)
“Salutations to Lord Rudra who is the Pranava (TARAKA) Mantra – OM”.
2.3 It is advised that the five gods Brahma, Vishnu, Rudra, Isvara and Shiva should be worshipped in the form of pranava [Aa + Uu + Ma + Nāda (sound) + Bindu (full stop)]. (Atharva Sikha Upanishad).
आश्रयाश्रयहीनोऽस्मि आधाररहितोऽस्म्यहम् । बन्धमोक्षादिहीनोऽस्मि शुद्धब्रह्मास्मि सोऽस्म्यहम् ॥९॥
III-9. I am free from the concept of substratum and that of the object resting on it; I am devoid of a prop. I am above captivity (bondage) and liberation, I am the pure Brahman, I am He. (Maitreya Upanishad).
eko hi rudro na dvitīyāya tasthur ya imāṃl lokān īśata īśanībhiḥ |
pratyaṅ janāṃs tiṣṭhati sañcukocānta-kāle saṃsṛjya viśvā bhuvanāni gopāḥ ||2||
Rudra is truly One; for the knowers of Brahman do not admit the existence of a second, He Ishana, alone rules all the worlds by His powers. He dwells as the inner Self (Atman) of every living being. After having created all the worlds, He, their Protector, takes them back into Himself at the end of time. (Śvetāśvatara Upaniṣhad III:1-21 of the Yajurveda).
I hope this clarifies all your queries.
