Neither. Sedimentary rocks are made out of sand, silt, clay, etc. Over time these can accumulate, and under sufficient pressure they are compressed into rock.

What is the most important information on sedimentary rocks?

Probably that they are sedimentary. =] They are made of sediments, and, unlike igneous and metamorphic rocks, are so far unaffected by magma/lava.


Is vindhyan system made of igneous rocks?

No, the Vindhyan system is primarily made up of sedimentary rocks. Igneous rocks, which are formed from the cooling of molten lava or magma, are not a dominant component of the Vindhyan system.


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.


Are sedimentary rocks made when molten lava cools?

No, sedimentary rocks are formed through the accumulation and compression of sediment (such as sand, mud, and organic material) over time. Lava cools and solidifies to form igneous rocks, not sedimentary rocks.

What class or rocks are made from lava or magma?

Rocks made from lava or magma are classified as igneous rocks. Igneous rocks form when molten rock cools and solidifies, either on the Earth's surface (extrusive) as lava or below the surface (intrusive) as magma. Examples of igneous rocks include basalt, granite, and obsidian.


How did rocks get formed?

There are 3 main ways for them to be formed. Sedimentary rocks are formed from dirt and sand, and can be found in rivers. Igneous rocks are made from molten magma or lava. Metamorphic rocks are made from already existing rocks, and are changed by pressure or temperature.


Scientists divide rocks into groups based on what?

Rocks are grouped by how they are formed. There are 3 types of rocks. Sedimentary, Metamorphic, and Igneous rock. Sedimentary rocks are made from broken down rocks, called sediment, which come from all three rocks. Metamorphic rocks come from existing rocks that are changed by heat and pressure. The Igneous rocks are formed from magma that rose up to the surface, also known as lava. When the lava cools and hardens it forms igneous rocks. That is a rock cycle.

Why are stalagmites and stalactites sedimentary rocks?

stalactites and stalagmites are sedimentary rock becausethey are made from sediment that as formed together. just like how igneous rock is formed by lava or magma that has cooled over time.


How is sedimentary rock relate to magma and lava?

because half of it is made of frozen or either hardend lava so it is related to lava


Are igneous rocks made up of igneous rocks?

Sedimentary rock can be made up partially of igneous clasts, but igneous rock is igneous rock.


What are some igneous and sedimentary rocks?

Igneous rocks are made from magma. Magma is made of melted rocks. (When it is underground it is called magma, when it erupts on the surface of the earth, it is called lava. It's the same material though.) When magma/lava cools, it forms igneous rocks. There are many types of igneous rocks and the specific type of igneous rock can vary according to which minerals are present in the melted rock, how fast it cools, and the presence of things like water. Sedimentary rocks are made out of tiny pieces of debris. This can include tiny rocks, sand, clay, silt, and organic material. (Organic materials can vary from rotted leaves to tiny, shelled ocean creatures, or many other types of organic material.) These bits of material collect in an area, then through compaction and cementation, they stick together to form sedimentary rocks. Sedimentary rocks can also be formed when minerals are dissolved in water and are then resolidified. This type of sedimentary rock is called a chemical sedimentary rock. Oolitic limestone is a good example of this type of sedimentary rock.
