how does rock cycle take place?
Answers
Answer:
The rock cycle is a process in which rocks are continuously transformed between the three rock types igneous, sedimentary and metamorphic. ... If the sediments are buried under further layers of sediment, they can become lithified to produce a sedimentary rock. Magma is produced when rocks are melted

Answer:
The rock cycle is a series of processes that create and transform the types of rocks in Earth’s crust.
Explanation:
We see rocks in our surrounding, from different shapes to size. Rocks never remain same and they are always changing with time. Rock cycle is a basic concept in geology that describes the time-consuming transitions through geologic time.
Rocks are constantly being recycled and go through several processes of chemical and physical changes. There are three main rock types:
- Sedimentary
- Metamorphic
- Igneous
When rocks are pushed deep under the earth’s surface, they may melt into magma. If the conditions no longer exist for the magma to stay in its liquid state, it will solidify into an igneous rock.
The rock exposed to high temperatures and pressures can be changed physically or chemically to form a different rock, called metamorphic.
Rocks exposed to the atmosphere are variable unstable and subject to the processes of weathering and erosion. This process breaks the original rock down into smaller fragments and carries away dissolved materials.

✯What are Rocks?
Rocks are mineral aggregates with a combination of properties of all the mineral traces. Any unique combination of chemical composition, mineralogy, grain size, texture, or other distinguishing characteristics can describe rock types.
✯Types of Rocks
- 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 may form with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.
☆Types of Igneous Rock
- Intrusive igneous rock: These rocks crystallize below the earth’s surface resulting in large crystals as the cooling takes place slowly. Diorite, granite, pegmatite are examples of intrusive igneous rocks.
- Extrusive igneous rock: These rocks erupt onto the surface resulting in small crystals as the cooling takes place quickly. The cooling rate is for a few rocks is so quick that they form an amorphous glass. Basalt, tuff, pumice are examples of extrusive igneous rock.
☆Igneous Rock Examples
- Basalt
- Diorite
- Granite
- Mica and quartz
✯Sedimentary Rock
The sedimentary rocks are formed by the deposition and subsequent cementation of that material within bodies of water and at the surface of the earth. The process that causes various organic materials and minerals to settle in a place is termed as sedimentation.
☆Types of Sedimentary Rock
- Clastic sedimentary rocks: These rocks are formed from the mechanical weathering debris. Sandstone, siltstone are examples of clastic sedimentary rocks.
- Chemical sedimentary rocks: These rocks are formed from the dissolved materials that precipitate from the solution. Iron ore, limestones are examples of chemical sedimentary rocks.
- Organic sedimentary rocks: These rocks are formed from the accumulation of plant and animal debris. Coal, some dolomites are examples of organic sedimentary rocks.
☆Sedimentary Rock Examples
- Halite
- Limestone
- Sandstone
- Siltstone
✯Metamorphic Rocks
The metamorphic rocks make up a large part of the Earth’s crust and are classified by texture and by chemical and mineral assemblage. They may be formed simply by being deep beneath the Earth’s surface, subjected to high temperatures and the great pressure of the rock layers above it.
☆Types of Metamorphic Rock
- Foliated metamorphic rocks: These rocks are produced by the exposure to heat and pressure which makes them appear layered. Phyllite, gneiss are examples of foliated metamorphic rocks.
- Non-foliated metamorphic rocks: These rocks don’t have layers. Marble, quartzite are examples of non-foliated metamorphic rocks.
☆Metamorphic Rock Examples
- Marble
- Quartzite
- Slate
- Phyllite
