What else can I help you with?
Could you tell me stuff about the rock Geode?
Geodes are rock cavities with internal crystal formations, usually made of quartz crystals. Some geodes are completely solid because they are filled with crystals. These are called "nodules". Geodes can form in gas bubbles in igneous rock, or in rounded cavities in sedimentary rock. Most geodes contain clear or white quartz crystals, but purple amethyst crystals are also common.
What rock formed in layers?
sedimentary rock
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 does sedimentary make sedimentary rock?
Sedimentary rock is formed when sediments are cemented together due to heat and/or pressure.
Rock that formed from other weathered rock is?
sedimentary
Are geodes metamorphic?
no its sedimentary rock feature
Is a geode a metamorphic rock?
No, a geode is not a metamorphic rock. Geodes are formed in sedimentary or igneous rocks and are cavities lined with mineral crystals. Metamorphic rocks are formed from existing rocks that undergo a transformation due to heat and pressure.
What are the 3 types of sedimentary?
Mechanically formed sedimentary rock , Chemically formed sedimentary rock and Organically formed sedimentary rock.

Rock type that is formed when sediment is lithified?
Sedimentary rock can be formed from lithified sediments.
Why are geodes found in some places and not others?
The presence of geodes appearing on the surface of a given locality is dependent on the geologic history of that area. Geodes are usually found in areas of exposed and eroded sedimentary rock. The shell of the geode, often quartz, weathers less vigorously than the entrapping rock, usually calcitic or dolomitic limestone. In northern lattitudes, glacial deposits may have covered up the geodes and sedimentary rock, or perhaps the sedimentary rock layer did not exist previously or has eroded away completely.
Are there geodes found in somerset NJ?
Yes, geodes can be found in Somerset, NJ. Geodes are typically formed in sedimentary and volcanic rock, and they may be discovered in various locations throughout the state, including Somerset County. It is important to obtain proper permissions before collecting geodes on private property or protected land.
What is a crystal lined rock called?
A crystal-lined rock is commonly referred to as a geode. Geodes are spherical rocks that contain a hollow cavity lined with crystals, typically formed in volcanic rocks or sedimentary deposits.
Sedimentary rock formed from sand?
Sedimentary rock formed from sand is called sandstone.
What rock formed in layers?
sedimentary rock
What rocks is formed in layers?
Sedimentary rock, like limestone, is formed in layers.
What kind of rock is formed form sediments?
Sedimentary rock.
