Why do some igneous rock have bigger mineral grains than others?
Wiki User

This is due to the rate of cooling - a slower rate of cooling results in large mineral grains because the molecules had time to maneuver into a crystalline lattice. A faster rate of cooling results in smaller mineral grains because the molecules were locked into place faster and therefore couldn't form the crystalline lattice structures before getting stuck.

Igneous rocks with larger mineral grains typically form from slower cooling rates, allowing more time for crystals to grow. Fast-cooling molten rock forms smaller mineral grains while slow cooling allows for larger crystal growth. Factors such as depth of formation, presence of water, or rate of cooling can influence the size of mineral grains in igneous rocks.

Is igneous rock red?
Not necessarily. Igneous rocks come in a variety of colors depending on their mineral composition. While some igneous rocks may be red due to the presence of minerals like iron oxide, many others can be black, white, green, or even multicolored.
Is igneous harder than sedimentary rocks?
Not necessarily. The hardness of a rock depends on its mineral composition and how it formed, rather than the type of rock it is. Some igneous rocks are harder than sedimentary rocks, while others may be softer. It varies depending on the specific rock type within each category.
Are igneous rocks strong?
Igneous rocks have a wide range of strengths depending on factors like mineral composition and cooling history. Some igneous rocks, like granite, can be very strong and durable, while others, like pumice, can be quite weak and easily crumble.
Does sand stone have calcite in it?
Sandstone typically does not contain calcite. Calcite is a mineral that is commonly found in limestone and marble, but not a typical component of sandstone. Sandstone is primarily composed of sand-sized grains of mineral, rock, or organic material cemented together by minerals such as quartz or feldspar.
What macromolecules are in grains?
Grains consist of carbohydrates mainly. There can be others too
Why do sedimentary rocks erode faster than others?
Sedimentary rocks tend to erode easily compared to other types of rocks as the grains within them are farther apart than the "grains" in, let's say, igneous rocks. As a result of this, the "grains" can be easily crumble. An example of this is sand.

Why do some igneous rocks have bigger crystals then others?
some of them are formed inside the earth and take 100's of years to form and form large cyclists in that time

Is quartz sedimentary or metamorphic?
Quartz is primarily a mineral found in both sedimentary and metamorphic rocks. It can form in sedimentary rocks through the accumulation and cementation of quartz grains. In metamorphic rocks, existing quartz can recrystallize under heat and pressure.

Why do sedimentary rocks wear away faster than others?
Sedimentary rocks are generally composed of loose grains that are not tightly bound together, making them more susceptible to weathering and erosion. In addition, sedimentary rocks often contain materials like clays and salts that are easily dissolved by water, further contributing to their faster wear.
When was Some Girls Are Bigger Than Others created?
Some Girls Are Bigger Than Others was created in 1986-06.
True or false igneous rocks are formed into layers?
False. Igneous rocks are formed from cooling and solidification of magma or lava and do not typically form layers like sedimentary rocks. Igneous rocks are usually crystalline with interlocking mineral grains.
Does sand stone have calcite in it?
Sandstone typically does not contain calcite. Calcite is a mineral that is commonly found in limestone and marble, but not a typical component of sandstone. Sandstone is primarily composed of sand-sized grains of mineral, rock, or organic material cemented together by minerals such as quartz or feldspar.
What is Stonehenge built from?
The major stones of Stonehenge are mostly sandstone, others are igneous rocks.
What do the poor in haiti eat?
They mostly eat grains such as rice and others aswell.
