when moss or lichen form on rocks these organisms break down rocks to the point it becomes soil
The inorganic portion of soil forms from rocks getting weathered by chemical and physical means to form soils.
Rocks and other sediments get weathered to a point where they are so small, becoming soil.
There are rocks which are known as weathered alteration rocks. But generally weathering leads to erosion. This eroded rock is called sediment, which can eventually form into sedimentary rocks.
Sedimentary rocks are made from weathered down materials, often rocks, so they can be argued that they come from other rocks. Metamorphic rocks are formed from pre-existing rocks; these rocks go under extreme heat and pressure. In conclusion, metamorphic rocks are definitely made from other rocks, and sedimentary rocks are sometimes made from other rocks. Sedimentary rocks are always made of other rocks,extrusive and intrusive igneous rocks as well as metamorphic rocks are weathered and eroded by agents like water , wind and sunlight and are stratified and compacted to form sedimentary rocks. Hence, even if metamorphic rocks are made from rocks, sedimentary rocks are definitely made from other rocks. Eg: sedimentary rock shale gets metamorphosed into slate and further metamorphosed into shcist which is the parent material of granite which can be effected by agents of weathering and erosion into sedimentary rocks again.
Yes, weathering slowly does break down rocks and makes them pebbles and then soil, but it takes years.

No. Those are igneous rocks. Sedimentary rocks from from the acummulation and lithification of weathered material.
Yes. Any rock can be weathered to form sediment.

A rock will breakdown physically into some type of sediment. Sediments such as: dirt, clay, sand, and pebbles. They can also breakdown chemically in solution.
Magma or Lava
The process by which natural forces move weathered rock and soil form one place to another is called (EROSION)
Rocks can be formed by particles of pebbles, sand or shells creating sedimentary rocks. When molten rock cools and hardens it will form igneous rocks. When there is pressure and intense heat on rocks, they form metamorphic rocks.
Technically rocks are not sediments, rather sediments are derived from weathered rock material. These sediments may conslidate and form rocks such as sandstones and mudstones, which include shales and siltstones. This variety of rock types is of sedimentary origin. Other types of rocks are formed by igneous and or metamorphic processes. Hope that answers your question.
