Does Rig Veda mention the Earth as moving?

Rig Veda 10.22.14 mentions kṣāḥ and translators indicated the meaning as the Earth.

अहस्ता यदपदी वर्धत क्षाः शचीभिर्वेद्यानाम् । शुष्णं परि प्रदक्षिणिद्विश्वायवे नि शिश्नथः ॥
ahastā yad apadī vardhata kṣāḥ śacībhir vedyānām | śuṣṇam pari pradakṣiṇid viśvāyave ni śiśnathaḥ ||

English translation:

While, handless and footless, the earth grew strong through the powers of her wise ways, you, circling him with skilful circumambulation, jabbed down Śuṣṇa for the whole of life.

===

Here lies the major issue.

kṣāḥ is a feminine plural word. However, translators mentioned it as a SINGLE EARTH, instead of multiple EARTHs.

Hence, according to my understanding, kṣāḥ in this Rik may not indicate the EARTH.

===

If understood esoterically, this Rik gives the following spiritual meaning.

• Elsewhere in Rig Veda (Rig Veda 5.31.2), the spiritual practice or saadhana was esoterically mentioned as a woman.
• Hence, kṣāḥ may not indicate the Earth, as generally translated. It may indicate the spiritual practices (plural)
• When Indra circles Śuṣṇa and "jabs him down for the whole of life," it signifies the Illuminated Will/MIND, ie, INDRA, permanently subduing and curbing inner weaknesses
• Indra eliminating Śuṣṇa, does not indicate any physical demon's elimination, but curbing the weaknesses of the practitioner,
• as Śuṣṇa is curbed, kṣāḥ (spiritual practices) will go strong.
