Why would the crystals in a intrusive igneous rock be larger than the crystals in a chemical sedimentary rock?
Crystals tend to be large if they form slowly either from the melt or from solution. Intrusive igneous rocks are formed when magma forces its way between existing rocks and then gradually cools and sets. The surrounding rocks provide good insulation, so the magma cools very slowly, and big crystals, such as those in granite, are formed. Chemical sedimentation processes vary, but are usually more rapid than intrusive igneous cooling.
Why do some substances crystallise while some don't?
Igneous rocks are formed when liquid rock (magma underground, or lava on the surface) cools down and solidifies. If cooling is slow, usually underground, the minerals have time to form large, visible crystals, e.g. in granite. If cooling is faster, on the surface of the Earth, the crystals can usually only be seen with a microscope. Occasionally, the lava cools extremely rapidly, for instance when lava hits cold water, and there is no time for any crystal formation. This results in a volcanic glass such as obsidian.
What type of crystals is formed from slow cooling?
If the magma cools down fastly the crystal size is small because the crystals do not have much time to form. If They magma slows down slowly the crystal size is big because it gives the crystals time to form! :D
How is peridot formed?
Peridot form in magma from the upper mantle (20 to 55 miles deep), and are brought to the surface by tectonic or volcanic activity where they are found in extrusive igneous rocks.
What happens when the gas cools to form water drops?
it's condensation
What rocks that form when magma cools underground?
granite is all that i know of.
Why do rocks form?
Igneous rocks form because, magma cools under the ground, or magma erupts, then cools on the ground forming these rocks.
Where does in intrusive igneous rock form?
formed when molten rocks called magma becomes trapped in small pockets . As these pockets of magma cools slowly underground, the magma becomes igneous rocks
Magma cools and solidifies to form what rocks?
igneous rocks
What rocks form when magma cools and hardens?
Igneous rock is what forms when magma cools and hardens.
What of rocks form when magma cools below earths surface?
Intrusive igneous rocks
How do igenous rocks form?
They form when magma or lava cools and solidifies.
How do gabbro and basalt rocks form?
The magma cools and forms both rocks
What does felsic magma make after its solid?
It will form granite if it cools underground and rhyolite if it cools at the surface.
What does igneous rock form from?
Igneous rocks are called fire rocks and are formed either underground or above ground. Underground, they are formed when the melted rock, called magma, deep within the earth becomes trapped in small pockets. As these pockets of magma cool slowly underground, the magma becomes igneous rocks.Igneous rocks are also formed when volcanoes erupt, causing the magma to rise above the earth's surface. When magma appears above the earth, it is called lava. Igneous rocks are formed as the lava cools above ground.
What igneous rocks form below Earths surface?
Igneous rocks that form below the Earth's surface are called intrusive igneous rocks. They crystallize when magma enters an underground chamber and cools very slowly.
Where do intrusives rocks form?
They form underground from the cooling and solidification of magma.
