What else can I help you with?
What factors can affect the texture of igneous rock?
The length of time the magma had to cool
What does not affect the type of igneous rock that forms?
The type of igneous rock that forms is primarily determined by the chemical composition of the magma from which it solidifies. Factors such as pressure and temperature can influence crystal size and texture, but they do not affect the type of igneous rock that ultimately forms.
Type of rock formed from molten rock?
Igneous rock is formed when magma cools and becomes solid.
What kind of rock is formed after a volcano erupts?
Extrusive igneous rock such as basalt, rhyolite, pumice, and obsidian.
When magma is cooled it becomes what?
Cooling and solidifying magma turns into igneous rock.
What factors and processes can affect the pathway that igneous rock takes in the rock cycles?
Melting and cooling

What two factors does an igneous rock form?
nothing!
What do you need for an igneous rock to form?
An igneous rock forms when molten rock cools and solidifies. This can happen beneath the Earth's surface (intrusive) or at the surface (extrusive). The key factors for igneous rock formation are heat, pressure, and time.
What factors can affect the texture of an igneous rock?
Factors that can affect the texture of an igneous rock include the rate of cooling, mineral composition, and the amount of gas bubbles present during solidification. A slower cooling rate typically results in larger crystals, while a rapid cooling rate usually produces finer-grained rocks. Higher gas content can lead to the formation of vesicles or pores in the rock.
Can igneous rock often be identified by their minerals?
Yes, igneous rocks can often be identified by their minerals because the minerals present in an igneous rock are usually specific to the conditions under which the rock formed. By studying the mineral composition of an igneous rock, geologists can determine factors such as the rock's cooling rate, temperature, and pressure during formation.
What describes rock that was formed when molten rock cooled down?
Igneous rock is formed.
What igneous rock is formed from magma or lava cools and hardens?
Cooled magma, lava, or pyroclastic material is igneous rock. Cooled magma forms intrusive igneous rock, while lava and pyroclastic material form extrusive rock. Anything beyond that depends on more specific factors.
Is obsidian metamorphic igneous or sedimentary?
Obsidian is an igneous rock.
Type of rock formed from molten rock?
Igneous rock is formed when magma cools and becomes solid.
