Weathering doesn't directly form new types of rock. It's the process that breaks down existing rocks into smaller pieces. However, the products of weathering can be used as ingredients in the formation of new rocks through the process of sedimentation.

Here's how it works:

* Weathering: Breaks down rocks into smaller pieces (sediments), like sand, silt, clay, or gravel.

* Erosion: Carries away these sediments, often by wind, water, or ice.

* Deposition: Sediments are dropped in a new location, usually in layers.

* Compaction & Cementation: Over time, the weight of the overlying layers compacts the sediments, and minerals dissolved in groundwater act as cement, binding the particles together.

This process, called lithification, forms sedimentary rocks. Here are some examples:

* Sandstone: Formed from sand grains.

* Conglomerate: Formed from larger gravel and pebbles.

* Shale: Formed from clay and silt.

* Limestone: Formed from the accumulation of shells, corals, or other marine organisms.

So, while weathering doesn't directly create new rock types, it provides the raw materials that are used to form sedimentary rocks through the process of sedimentation.
