Sedimentary, igneous and metamorphic.
There are three types of rocks: 1)Igneous Rocks 2)Sedimentary Rocks 3)Metamorphic Rocks
There are three major types of rock: igneous (formed from the cooling and solidification of magma or lava) sedimentary (laid down as sediments) and metamorphic (changed by heat and/or pressure)
They are igneous, sedimentary, and metamorphic due to weathering, erosion, heat, and pressure
Pebbles could be igneous, metamorphic, or sedimentary rocks.
This is a very simplistic answer. But, it should reveal the basic processes involved in rock formation.1. Sedimentary, like coal and limestone. They are made from particles of substances that settle and coalesce into a layer that becomes rock.2. Igneous, like granite and basalt. These rocks were formed by heat. Think of lava.3. Metamorphic: Marble and slate. These are rocks that were in another form and got changed by pressure into their present form.
Igneous, Sedimentary, and Metamorphic
The rock cycle.
The three groups are igneous, sedimentary, and metamorphic. igneous forms when magma or lava cools down. sedimentary forms when sediments (clay, sand, silt etc) gets compressed. and metamorphic forms when an igneous or sedimentary goes under very high temperatures and pressure
Igneous, sedimentary, metamorphic, and extraterrestrial.
The rock cycle.
No. Igneous, sedimentary, and metamorphic rocks are three different categories of rock.
Sedimentary rocks are often used for decorative landscapes and as building materials. Three of these include limestone, sandstone and dolomite.
