Are there any steps of the rock cycle that do not connect directly to one another

No

ALL rocks are connected in a cycle of creation, change, and destruction which is known as what is referred to as the rock cycle.

The rock cycle begins with molten rock, i.e, the magma below ground and the lava above ground, which cools and hardens to form igneous rock. These sediments can then be buried and hardened forming sedimentary rock.

A rock is a solid mass of geological materials. They are naturally formed, non-living earth material. Rocks are made of collections of mineral grains that are held together in a firm solid mass

The three main rock types are igneous, metamorphic and sedimentary.

The three processes that change one rock to another are crystallization, metamorphism, and erosion and sedimentation.

Any rock can transform into any other rock by passing through one or more of these processes. This creates the rock cycle.
