Earth Science for Kids: Rocks, Rock Cycle, and Formation. Kids learn about the science of rocks and the rock cycle. How different types such as igneous, sedimentary, and metamorphic form from minerals with the help of nature.
Igneous rock, any of various crystalline or glassy rocks formed by the cooling and solidification of molten earth materialIgneous rocks constitute one of the three principal classes of rocks, the others being metamorphic and sedimentary Igneous rocks are formed from the solidification of magma, which is a hot (600 to 1,300 °C, or 1,100 to 2,400 °F) molten or partially molten rock material...
Metamorphic rocks started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form. Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some

Metamorphic Rocks - Columbia University. Non-foliated metamorphic rocks include quartzite, which is metamorphosed sandstone in which the quartz grains have recrystallized into a very solid interlocking network, and marble, which is metamorphosed limestone composed of recrystallized and interlocking calcite or dolomite crystals.
Metamorphic Rocks Rock formed when another rock (a parent rock or protolith) changes (by becoming more compact, minerals changing size, new minerals growing, minerals aligning) into a new rock. This happens when the parent rock is exposed to high pressure, high temperature, and/or hydrothermal fluids.
Igneous Rocks; Sedimentary Rocks; Metamorphic Rocks; Igneous Rock. Igneous rock is one of the three main rock types. Igneous rock is formed through the cooling and solidification of magma or lava. Igneous rock is one of the three main rock types.

Metamorphic rocks are formed from the alteration of preexisting rock types (igneous, sedimentary or already formed metamorphic rocks) through metamorphism. The preexisting rock, also known as protolith, is subjected to both heat and pressure, which causes chemical or physical changes.

The rocks found in Pakistan can be classified into three major groups, viz. the igneous rocks, the sedimentary rocks and the metamorphic rocks. In the Himalayan regions, the common rock types are metamorphic which are gneisses, schist, slates and phyllites with some quartzite and marble.
Clastic sedimentary rocks form when individual grains (the sediment) made by fragments of rocks minerals or shells are cemented together (the clastic sediemntary rock). These are the only type of rock that is NOT made simply of crystals but rather fragments of other materials broken and …
The Rock Cycle is a group of changes. Igneous rock can change into sedimentary rock or into metamorphic rock. Sedimentary rock can change into metamorphic rock or into igneous rock.

Sedimentary rock is one of the three main rock groups (along with igneous and metamorphic rocks) and is formed in four main ways: by the deposition of the weathered remains of other rocks (known as 'clastic' sedimentary rocks); by the accumulation and the consolidation of sediments; by the deposition of the results of biogenic activity;,
For extracting sedimentary rock, the chief tool was the mason's pick with a 2.5-kilogram metal head and a 45-centimetre haft. With these picks vertical channels as wide as a man were cut around rectangular blocks, exposing five faces.
