sedimentary rocks are formed by weathering.

Igneous rocks are formed by cooling of magma .

Metamorphic rocks r formed by change in temperature and pressure inside earth.

Answer 2

1. Sendimentary rocks are formed previously from existing rocks which are known as parent rock.But, igneous rocks are formed when magma or molten matter originating from inside the Earth reaches its surface and solidifies. But metamorphic are formed sometimes due to high pressure and temperature, both igneous and sedimentary rocks undergo a complete change in their appearance and composition and form a completely different rock known as metamorphic rock.

2. Examples of sedimentary are stones, clay, chalk and Gypsum. But, examples of igneous rocks are Granite and basalt. But example of metamorphic rocks are marble and slate.
