Rocks without a specific, recognizable form are typically called amorphous rocks.

Here's why:

* Amorphous means "without form" or "shapeless".

* Rocks are naturally occurring solid materials composed of minerals.

While the term "amorphous" is most often used to describe the structure of materials at the molecular level, it can also be used to describe rocks that lack a defined shape, such as:

* Unconsolidated sediments: These are loose, fragmented materials like sand, gravel, and clay that haven't been cemented together.

* Some volcanic rocks: Some volcanic rocks cool so quickly that crystals don't have time to form, resulting in a glassy, amorphous texture.

However, it's important to note that most rocks do have some kind of form, even if it's not perfectly symmetrical or easily recognizable.
