Igneous is derived from the Latin word for fire (ignis), which is very appropriate since igneous rock can be created by volcanic action. It is the oldest form of rock and can be found where ever the earth's crust has been opened by volcanoes or earthquakes, allowing molten rock to seep to the surface. (Think: Islands!)
Four types of igneous rock exist:
1. Obsidian: extrusive (forced to the surface) igneous rock that is actually glass and not minerals. Sharp edges, smooth surface.
2. Pumice: another extrusive igneous rock but, unlike obsidian, this volcanic rock was pitted by millions of tiny air bubbles. It, too, is glass and not minerals... and it can float!
3. Granite: very hard igneous rock formed deep within the earth and composed of feldspar and quartz. This is intrusive igneous rock because it is formed below the surface of the earth.
4. Scoria: extrusive, glass, with a pitted surface much like pumice. Scoria is more dense and has a darker color with much larger pits.

How can igneous rock disturb sedimentary rock layers?
Igneous rocks can disturb sedimentary rock layers and formations by their movement during ascent through such layer. when they make contact with this sedimentary rocks they could result to folding and/or metamorphism.

How do igneous rocks from into a sedimentary rock?
igneous rocks mix with metamorphic rocks and they combine together to make a sedimentary rock. the three themes of science rocks are metamorphic,igneous, and sedimentary.
What sort of rocks can igneous rocks make?
Igneous rocks can be transformed not made but i think you are asking what types of rocks are igneous rocks well any rock that had once been lava/molten is an igneous rock and lava/molten comes from volcano.You might want to search on Google-types of igneous rocks or how can igneous rocks be transformed.

What aren't you likely to find a fossil I metamorphic rock or igneous rock?
The fossils will be crushed under the pressures required to create metamorphic rocks and they will melt in the heat required to make igneous rocks.
Why did the igneous rocks are always hard?
refer to mode of formation of igneous rock, they are formed due to solidification of molten magma(lava) from within the earths crust. thus igneous rock become the major source of other rocks kind and it also contain different kind of minerals that make its hardness, other rock originate from igneous rock after some processes
