Conglomerate rocks don't have a specific shape. They are composed of rounded fragments of other rocks (gravel, pebbles, cobbles, or boulders) cemented together by a finer-grained matrix.

Therefore, the shape of a conglomerate rock depends on the shape of the rock fragments it contains and the way they are cemented together.

Here are some ways to describe the shape of a conglomerate:

* Angular: If the fragments are sharp and jagged

* Rounded: If the fragments are smooth and rounded

* Irregular: If the fragments are a mix of shapes and sizes

* Blocky: If the fragments are large and have a rectangular shape

Conglomerate rocks can be found in various shapes and sizes, depending on their origin and formation.
