Weathering doesn't directly "cause" rocks. Instead, it breaks down existing rocks into smaller pieces. These pieces are then often transported and deposited elsewhere, where they can eventually form new rocks.

Here's a breakdown:

* Weathering: The process of breaking down rocks, soils, and minerals through contact with the Earth's atmosphere, water, and biological organisms.

* Erosion: The process of moving weathered material from one location to another.

* Deposition: The process of dropping off the weathered and eroded material.

* Sedimentary Rocks: These rocks are formed from the accumulation and cementation of weathered and eroded material.

So, while weathering doesn't create rocks, it plays a vital role in the formation of sedimentary rocks.

Examples of sedimentary rocks formed from weathered material:

* Sandstone: Formed from sand grains (weathered from igneous or metamorphic rocks)

* Conglomerate: Formed from gravel (weathered from various rocks)

* Limestone: Formed from the accumulation of shells and other marine organisms (weathered from calcium carbonate)

* Shale: Formed from fine-grained clay (weathered from various rocks)

It's important to remember that the original rock that was weathered can be any type: igneous, metamorphic, or even other sedimentary rocks. Weathering breaks them down, and then those fragments are used to form new rocks.
