Sedimentary rocks are the result of weathering, and erosion of other rocks within the rock cycle and from the death and deposition of organic material. Igneous Rocks vary from mafic to felsic mineral content, and are produced under great pressure and heat within the earth, being extruded onto the surface by volcanic eruptions, or revealed by the weathering of surrounding rocks, revealing cooled magma chambers, dykes etc.

As igneous rocks are eroded by natural processes, the fragments of quartz, pyroxene, feldspar and other minerals gets broken down into fine particles, which in turn become buried and compacted, gradually forming sedimentary layers.

e.g Sandstone and Granite both contain quartz, but sandstone is sedimentary and granite is igneous.

Which came first sedimentary igneous metamorphic rocks?

Metamorphic rock would probably have been the first rock type formed after the initial formation of the first igneous rock. Sedimentary rock formation relies on weathering and erosion, whereas metamorphic rock can be created by heat and pressure. It's likely that rock was metamorphosed before weathering existed .


What are the kinds of rocks?

All rocks are solid. Igneous, metamorphic, or sedimentary.


Are thunder eggs sedimentary and igneous rocks?

Thunder eggs are technically both sedimentary and igneous rocks. They are formed when gas bubbles in volcanic lava solidify and are later filled with various minerals, such as quartz. So, they have characteristics of both sedimentary (formed through deposition) and igneous (formed through cooling of magma or lava) rocks.


How are sedimentary metamorphic and igneous formed?

metamorphic - formed when igneous or sedimentary rocks are put under extreme heat and/or pressure. igneous - volcanic rock (comes from a volcano) sedimentary - particles of rock/sand/shells/clay etc. 'gathered' to make a rock.


How are rocks classified into one of these three groups?

Rocks are classified into three groups based on how they are formed. Igneous rock is formed when magma cools and crystallizes. Sedimentary rock is formed when the products of weathering and erosion are compacted and cemented to form new rock. Metamorphic rock is formed when existing rock is changed by heat, pressure or chemical change into a new kind of rock.

What is sedimentary rock is formed from clay deposits?

Claystone, and shale are sedimentary rocks formed from lithified deposits of clay.


Rocks are classified as igneous sedimentary or metamorphic based primarily on their?

Rocks are classified as igneous, sedimentary, or metamorphic based primarily on their origin and how they were formed. Igneous rocks are formed from cooled magma or lava, sedimentary rocks are formed from the accumulation of sediments, and metamorphic rocks are formed from the alteration of existing rocks due to heat and pressure.


Name the 3 kinds of 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.

Is Sedimentary rocks are derived from igneous rocks?

Sedimentary rocks are not directly derived from igneous rocks. Sedimentary rocks are formed from the accumulation and cementation of sediments, such as sand, mud, and organic material, through processes like erosion, deposition, and lithification. Igneous rocks, on the other hand, are formed from the cooling and solidification of magma or lava.


What makes the 3 types of rocks different?

The three types of rocks - igneous, sedimentary, and metamorphic - are different in terms of how they are formed. Igneous rocks are formed from the cooling and solidification of molten material, sedimentary rocks are formed from the accumulation and cementation of mineral and organic particles, while metamorphic rocks are formed from the alteration of existing rocks due to heat and pressure within the Earth's crust.

What is the difference between igneous and sedimentary rocks?

Igneous rock is formed from the solidification of magma or lava. Sedimentary rock is formed from the lithification of sediments, generally.


What are the three types of rock and their formation?

How are metamorphic and sedimentary igneous rocks formed?

Igneous- Formed from hot molten magmaSedimentary- formed from sediments piling up creating layersMetamorphic- Formed when intense heat AND pressure are applied to an igneous or sedimentary rock.


How many differant types rocks are there?

there are 3 types of rocks- Igneous Rocks, Sedimentary Rocks, and Metamorphic RocksThere are three main type of rocks in the world. The names are Igneous, Sedimentary, and Metamorphic.The three main types, or classes, of rock are sedimentary, metamorphic, and igneous and the differences among them have to do with how they are formed. Sedimentary.
