Igneous rock is formed when molten rock cools. Examples are lava from volcanoes cooling but also rock that is pushed from the magma layer into cooler pockets under the surface of the Earth. They are characterised by having crystals in them. The larger the crystal the longer it took to cool down and form a solid.
Sedimentary rocks are formed when small particles (sediments from weathering and erosion) are deposited at a particular site - usually the slow running bits of river. These particles are, over millions of years, pushed together so much that any water in between the particles is pushed out and the particles get cemented together. A typical characteristic of sedimentary rock is that if you scratch it the particles will be scraped off and that they absorb water. They can also contain fossils.
Metamorphic rock is formed when sedimentary, igneous or other metamorphic rock ends up, because of plate movement, in a position where it is exposed to high pressure and temperature. This changes the nature of the original rock into something new. Characteristics of metamorphic rock is that there are no crystals or visible grains, it doesn't absorb water and is quite hard.

Sedimentary rocks have numerous fossils
The three types of rocks in the rock cycle are igneous, sedimentary, and metamorphic rocks. Igneous rocks form from molten rock cooling and solidifying. Sedimentary rocks form from the accumulation and compaction of sediments. Metamorphic rocks form from the alteration of existing rocks under high pressure and temperature.
All rocks are solid. Igneous, metamorphic, or sedimentary.

Metamorphic rocks originate as igneous and sedimentary rocks, but have been changed by heat and pressure.
The three types of rocks involved in the rock cycle are igneous rocks, sedimentary rocks, and metamorphic rocks. Igneous rocks form from the solidification of molten magma, sedimentary rocks form from the deposition and lithification of sediments, and metamorphic rocks form from pre-existing rocks that are subjected to high heat and pressure.
Metamorphic rocks can form from both igneous and sedimentary rocks through the process of heat and pressure, but they are more commonly associated with forming from existing metamorphic or sedimentary rocks. Igneous rocks can indirectly contribute to the formation of metamorphic rocks by heating up and altering surrounding rocks, leading to the formation of new metamorphic rocks.
The three main types of rocks are igneous, formed from cooling lava or magma; sedimentary, formed from compressed layers of sediment; and metamorphic, formed from existing rocks that undergo high heat and pressure.

Three (3) rocks in the rock cycle are sedimentary, igneous, and metamorphic rock.
Igneous, sedimentary, and metamorphic rocks are the three main types of rocks. Igneous rocks are formed from the cooling of molten rock, sedimentary rocks from the accumulation of sediment, and metamorphic rocks from the transformation of existing rocks under heat and pressure.
The three classes of rocks are igneous, sedimentary, and metamorphic. Igneous rocks form from the cooling of magma or lava, sedimentary rocks result from the accumulation and compression of sediment, and metamorphic rocks form from the alteration of existing rocks due to high heat and pressure.
