Hi Leshem, Both words can be used interchangeably at times, but they also have some differences. While "Earth" (with a capital E) refers to our planet, "earth" can refer to "soil" which plants can grow and anchor themselves firmly into. The word "ground" can also refer to "earth" or "soil". (Example: Young seedlings sprouted from the ground.) "Ground" also refers to the solid surface of planet Earth. You can be standing on the rocks at the summit of a tall mountain. That can be the "ground". You can be standing at a plaza. That can be the "ground". So while there are similarities, there are also differences. Hope this helps. Cheers, Lance

Saying that a seed grows from the Earth is correct, and so is saying that a seed grows from the soil. In the context you stated, both words refer to the ground. Saying that the seed grows from the ground/soil is more technically correct with regards to science, but some English speakers call the "ground" the "Earth," either in a joking way, or just as a common expression. The main difference between the actual definition of the words is that "Earth" refers to the planet we live on, while "soil" is another word for dirt where you can grow plants/crops.

It depends on the context. English has many words for concepts which are more appropriate in different settings, for example soil makes a great candidate for a technical use. Earth is more archaic and in my opinion would make an excellent choice for prose.
