As'salamu Alaikum Everyone,
Zakir, notice how they at least drew earth as a round object.
Dahaha in the Glorious Quran means:
1- To push something and make it roll as in rolling an object down the road or hill.
2- Spherical.
3- To expand.
So when Allah Almighty says that the earth He
DAHAHA, it means that He
expanded it spherically:

Now as to the seven spherical layers, Allah Almighty specifically said that they are the sky of the earth. They are not seven planets as presented in the image that you gave.
As to seven earths, that is a gross misunderstanding, because Allah Almighty
never said 7 earths. Allah Almighty Said that
"He Created the Seven Heavens, and of the earth similar to them." This is because the Heavens are not exactly the same. They are similar. And each has many earths. So the number of earths that support life similar to ours vary between Heaven to Heaven. And I have proven beyond any doubt from the Glorious Quran that earth in the Quran is both singular and plural. In fact, the very verse that the infidels misuse (the one I quoted) is speaking of earth in the plural also.
