Igneous Rocks
What do Intrusive Rocks look like?
What are Crystalline Rocks?
Crystalline sedimentary rocks form from chemical reactions in which minerals within water form crystals.
What is mineral alignment and which texture does it belong to?
Foliated. The minerals are arranged in a parallel layer.
What do Extrusive Rocks look like?
very fine-grained, small or no holes/crystals
How can a metamorphic rock become igneous?
If the newly formed metamorphic rock continues to heat, it can eventually melt and become molten (magma). When the molten rock cools it forms an igneous rock.
How do Extrusive rocks form?
Extrusive rocks are formed on the surface of the Earth from lava.
What are Bioclastic Rocks?
Bioclastic rocks are sedimentary rocks that are made up of organisms that have hardened and cemented together.
What is non foilated rocks?
Rocks where individual mineral grains do not align.
What do Clastic Rocks Look Like?
Clastic sedimentary rocks may have particles from microscopic clay to huge boulders.
How do igneous rocks become sedimentary rocks?
On the surface, weathering and erosion break down the igneous rock into pebbles, sand, and mud, creating sediment, which accumulates in basins on the Earth's surface. As successive layers of sediment settle on top of one another, the sediment near the bottom is compressed, hardens, and forms sedimentary rock.
How do Intrusive Rocks Form?
Intrusive rock forms when magma is trapped deep inside the Earth.
What are clastic rocks?
Clastic rocks are composed of fragments of pre-existing minerals and rock.
What is foliated rocks.
Foliation refers to repetitive layering in metamorphic rocks.
What do Bioclastic Rocks Look Like?
Bioclastic rocks are comprised of compacted plant or animal remains.
How do sedimentary rocks become Igneous rocks?
If a sedimentary rock is subjected to intense heat it will melt. Once it rises up and cools down, it will form an igneous rock.
What are the 2 igneous rock textures?
Intrusive and Extrusive
What are the 3 textures?
clastic, bioclastic, crystalline
What are the 2 textures of Metamorphic rocks?
Foilated and Non foilated.
What do Crystalline Rocks Look Like?
Rocks where its shiny and Crystals are visible
How do sedimentary rocks become metamorphic rocks?
They form by intense heat and pressure.
how do igneous rocks form?
Igneous rocks form when hot, molten rock crystallizes and solidifies.
How are sedimentary rocks formed?
What are Sedimentary rocks are formed when layers of sediments build up over time and harden to form a rock with many layers?
How are metamorphic rocks formed?
Metamorphic rocks are created when another type of rock is exposed to extreme levels of heat or pressure. Metamorphic rocks are created when another type of rock is exposed to extreme levels of heat or pressure.
What is Banding and which texture does it belong to?
Foliated. Banding means that the rock consists of alternating, thin layers
What is sediments and how is it formed?
Sediment is solid material that is moved and deposited in a new location. Sediment can consist of rocks and minerals, as well as the remains of plants and animals.
