What determine the texture of igneous Rock?
The texture is mostly determined by the time spent in cooling from magma or lava. The quicker the transition from molten to solid, the finer the texture.
What are the features of intrusive igneouse rocks?
Intrusive igneous rocks form underground from magma that cools slowly, resulting in coarse-grained textures. They have large mineral crystals visible to the naked eye, such as feldspar, quartz, and mica. Examples include granite, diorite, and gabbro.
How does erosion effect the rock cycle?
erosion can effect the rock cycle by turning igneouse and metamorphic rocks into sediments and eventualy turn into a sedimentary rock such as sandstone
What factor can affect the texture of metamorphic rock?
The temperature and pressure conditions during metamorphism can affect the texture of metamorphic rock. Higher temperatures and pressures typically lead to a more pronounced foliation and mineral alignment, resulting in a finer texture. Additionally, the presence of fluids during metamorphism can also influence the development of specific textures in metamorphic rocks.
What does igneous rock texture refer?
Igneous rock texture refers to the size, shape, and arrangement of the mineral grains within the rock. It is primarily influenced by the cooling rate of the molten material; for example, slow cooling allows for the formation of larger crystals, resulting in a coarse-grained texture, while rapid cooling produces smaller crystals and a fine-grained texture. Textures can also include features like porphyritic (large crystals in a finer matrix) or glassy (no crystalline structure). Overall, texture provides insight into the rock's formation history and environment.
What are the 2 types of igneouse rock?
plutonic and volcanic
How are igneouse rock formed?
when you apply heat and pressure to it
What kind of texture does a rock with large crystals scattered on a background of much smaller crystals have?
The rock would have a porphyritic texture, with large crystals (phenocrysts) embedded in a finer-grained matrix (groundmass). This texture is typically the result of two stages of cooling during the formation of the rock, where the larger crystals formed first deep in the Earth and then the finer-grained matrix formed as the magma moved closer to the surface.
How are igneouse rock made form?
when you apply heat and pressure to it
Is coal a igneouse rock?
No. It is considered a sedimentary rock, except for the variety anthracite, which is considered a metamorphic rock.
What are the large crystals called in an igneous rock mostly composed of a finer grained matrix?
The large crystals are called phenocrysts and the finer grained matrix is known as the groundmass. This texture is known as porphyritic texture, where the rock has two distinct crystal sizes.
What determine the texture of igneous Rock?

Does a rocks grain give the rocks its texture?
Yes, a rock's grain size will help determine its texture. The size and arrangement of mineral grains within a rock will affect how the rock feels to the touch. Finer-grained rocks tend to have a smoother texture, while coarser-grained rocks may feel rougher.
What factor can affect the texture of metamorphic rock?
The temperature and pressure conditions during metamorphism can affect the texture of metamorphic rock. Higher temperatures and pressures typically lead to a more pronounced foliation and mineral alignment, resulting in a finer texture.

What is the extrusive igneouse rock that floats?
"Pumice." It is light and porous (filled with air pockets), which makes it significantly less dense than the average rock.
