Which rocks have the most air spaces grainy rocks or crystal rocks?
Grainy rocks tend to have more air spaces compared to crystal rocks. This is because grainy rocks are composed of loosely packed grains, allowing for more air to be trapped between the particles. Crystal rocks, on the other hand, have a more tightly packed crystalline structure with little to no space for air.
What is marbles crystal?
Marble is a rock and rocks don't have crystal structures. However, marble does have a crystalline texture of visible interlocked calcite or dolomite mineral grains.
Which rock absorbs water grainy rocks or crystal rocks?
Grainy rocks not only absorbs water better than crystal rocks, but it filters the water as well.
What is the parallel crystal arrangement of layers in metamorphic rock called?
The parallel crystal arrangement of layers in metamorphic rock is called foliation. Foliation is a common feature in rocks that have undergone intense heat and pressure, resulting in the alignment of mineral grains into distinct layers.
Does slow cooling of igneous rocks form large or small crystal grains?
Slow cooling of igneous rocks typically forms large crystal grains. This is because slow cooling allows more time for mineral grains to grow, resulting in larger crystals. Examples of rocks formed through slow cooling and having large crystal grains include granite and gabbro.
What are rocks that have grains that lie in a pattern of flat layers or form swirls?
Rocks with grains that lie in flat layers are sedimentary rocks, which include sandstone and shale. Rocks with swirling patterns are often metamorphic rocks, such as gneiss or marble, which have undergone intense heat and pressure causing their minerals to align in distinct patterns.
What Evidence Would You Look For If Attempting To Classify A Piece of igneous Rock as Extrusive?
Extrusive igneous rocks have very small crystal grains.
Why do some igneous rocks have big crystals or grains and some igneous rocks have small crystals or grains?
Igneous rocks with big crystals or grains form from slow cooling beneath the Earth's surface, allowing time for larger crystals to grow. In contrast, igneous rocks with small crystals or grains form from fast cooling at or near the Earth's surface, limiting the time available for crystal growth.
What is lithofication?
Lithification is the process by which loose sediment is transformed into solid rock through compaction and cementation. It involves the squeezing together of sediment grains and the binding of these grains by minerals dissolved in the groundwater, resulting in the formation of sedimentary rocks.
What are rocks that have visible layers and elongated mineral grains?
Rocks with visible layers and elongated mineral grains are called foliated rocks. These rocks form under high pressure and temperature conditions, causing minerals to align in layers or elongate in a specific direction. Examples include schist and gneiss.
Rough texture rocks have grains and fine textured rocks have grains?
Yes m that it true, other than glasses all rocks have grains.
What 2 things are applied to igneous or sedimentary rocks that make metamorphic rocks form?
Heat and pressure are applied to igneous or sedimentary rocks to make metamorphic rocks form. Heat causes mineral grains to recrystallize, while pressure helps to rearrange the mineral structure within the rock.
