Explanation:

Uplift is a geological process that raises the elevation of rocks. In the rock cycle, it brings rocks that have formed deep within the Earth (such as igneous rocks formed from magma cooling or metamorphic rocks formed due to heat and pressure) to the Earth's surface. Once at the surface, these rocks are exposed to weathering (physical, chemical, and biological processes that break rocks down) and erosion (the movement of weathered materials by agents like water, wind, ice). The weathered and eroded materials can then be transported and deposited, eventually forming sedimentary rocks through lithification. So, uplift is crucial as it initiates the part of the rock cycle where rocks are exposed to surface - level processes (weathering, erosion, sedimentation) that lead to the formation of new rock types (sedimentary rocks in this case).

Answer:

Uplift brings rocks formed deep within the Earth (igneous or metamorphic) to the surface. At the surface, these rocks are weathered and eroded. The eroded materials can be deposited and form sedimentary rocks. Thus, uplift is essential as it starts the process of rocks being exposed to surface - level processes (weathering, erosion, sedimentation) which are part of the rock - cycle progression.
