Weathering, erosion, deposition, compaction, and cementation.
Igneous, metamorphic, and existing sedimentary rocks can weather and erode to form sedimentary rocks. Igneous and metamorphic rocks can break down into sediments through processes like weathering and erosion, which then may accumulate and lithify into sedimentary rocks. Existing sedimentary rocks can also be reworked and lithified to form new sedimentary rocks through processes like compaction and cementation.
Normally when sedimentary rocks are squashed and heated they do indeed change, they become metamorphic rocks. e.g. mud will be turned into slate - limestone into marble etc.As the metamorphic temperature and pressure increase still further, most sedimentary rocks end up as Granulites or Banded Gneisses which look very much like igneous rocks (Granites).In the extreme, sedimentary rocks can melt, and these melts will form new magmas which will eventually harden to form new igneous rocks.
No, pebbles are not necessarily igneous rocks by default. Pebbles can be formed from a variety of rock types, including igneous, sedimentary, and metamorphic rocks, depending on the geological processes that created them.
No, igneous rocks are harder than sedimentary rocks on average.
I know one of them...Sedimentary hope i helped... =) All 3 are igneous, sedimentary, and metamorphic.
The rock cycle
Igneous rocks change to Metamorphic rocks through heat and pressure. Igneous rocks change to sedimentary rocks through weathering and erosion until the igneous rock is sediments. The sediments then compact to form sedimentary rocks.

they change into metamorphic rocks
Igneous rock can change into sedimentary rock or into metamorphic rock. Sedimentary rock can change into metamorphic rock or into igneous rock. Metamorphic rock can change into igneous or sedimentary rock.
Igneous rocks are a "finished product". They do not become sedimentary rock - though sedimentary rocks, with heat and pressure can become metamorphic rocks.

Sedimentary rocks are not directly derived from igneous rocks. Sedimentary rocks are formed from the accumulation and cementation of sediments, such as sand, mud, and organic material, through processes like erosion, deposition, and lithification. Igneous rocks, on the other hand, are formed from the cooling and solidification of magma or lava.
Sedimentary rocks make up about 75% of Earth's crust by volume, while igneous rocks make up about 15-20%. Sedimentary rocks form through processes like erosion, deposition, and cementation, while igneous rocks form from the cooling of molten magma.
