Sedimentary rock is composed of minerals. The minerals may be in the form of particles of other rocks that are made of minerals themselves, as well as the minerals of the cementing material that holds those particles together. In certain cases, the minerals have formed as a result of the evaporation of or precipitation from saturated solutions containing the components of minerals. Sedimentary rocks can contain visible crystals as well as crystals that are not visible without the aid of magnification.

In other words, no.

Is shale a volcanic rock with small crystals made when lava cools?
No. Shale is a sedimentary rock formed from mud.
Does conglomerate have any crystals?
Well, Conglomerate is a sedimentary rock and sedimentary rocks are not crystalline in nature, but they do consist of mineral crystals such as Quartz.
Are sedimentary rocks formed because of water evaporating and leaving crystals behind?
Some sedimentary rock is formed this way; chemical sedimentary rock formed from evaporites, like rock salt, and rock gypsum.
What are sedimentary rock crystals?
In general, sedimentary rock crystals would be crystals that are found in sedimentary rocks. Normally they are calcite or quartz as they are the minerals most likely to cement sediments to form sedimentary rocks. There is a group of sedimentary rocks called evaporites that include crystals of salt, gypsum, sylvite, glauberite, thenardite, mirabilite and a few others. However, there is a tremendous variety of other minerals that can produce crystals in sedimentary rocks. Geodes from Indiana, Illinois, and Kentucky can have crystals of barite, millerite, sphalerite, galena, fluorite, and aragonite. In other areas of the planet crystals of azurite and malachite can be found in sedimentary rocks. There are many, many other types of crystals that have been found in sedimentary rocks.
Can sizes of crystals in sedimentary rock tell us how quickly the lava or magma cooled that formed the rock?
Yes it can.
What is rock made of bits of sedimentary material that was compacted in layers?
A rock is amineral
Is shale a volcanic rock with small crystals made when lava cools?
No. Shale is a sedimentary rock formed from mud.
What type of sedimentary rock forms when crystals grow out of solution?
These minerals are called evaporites.
What process changes a sedimentary rock into an igneous rock?
Sedimentary rock can change intometamorphic rock or into igneous rock. Metamorphic rockcan change into igneous or sedimentary rock. Igneous rock forms when magma cools and makes crystals. Magma is a hot liquid made of melted minerals.
Does conglomerate have any crystals?
Well, Conglomerate is a sedimentary rock and sedimentary rocks are not crystalline in nature, but they do consist of mineral crystals such as Quartz.
Does a rock have a Crystal in it?
yes it does. Even a igneous rock and a sedimentary rock and a metamorphic rock all have crystals in them.
Is metamorphic rock crystalline or composed of crystals?
Metamorphic, igneous, and sedimentary rock are all composed of crystals, which vary greatly in size.
How big are the particles in metamorphic rock compared to those in sedimentary rock?
If by particles you mean the size of the crystals, then the crystals in metamorphic rock are often larger than in the sedimentary rock. High heat and pressure can cause the minerals to recrystallize. This would be the case in the metamorphosis of limestone (sedimentary) to marble (metamorphic).
Are sedimentary rocks formed because of water evaporating and leaving crystals behind?
Some sedimentary rock is formed this way; chemical sedimentary rock formed from evaporites, like rock salt, and rock gypsum.
How would you know the difference between igneous and sedimentary and metamorphic rock?
Sedimentary rocks tend to have layers. Igneous rocks tend to have crystals. If you don't see layers or crystals, the rock might be metamorphic.

What kind of rock is made of sedimentary rock?
The answer is organic sedimentary rock.
