The change of rock composition most responsible for creation of magma is the addition of water. Water lowers the solidus temperature of rocks at a given pressure. For example, at a depth of about 100 kilometers, peridotite begins to melt near 800°C in the presence of excess water, but near or above about 1500°C in the absence of water
What else can I help you with?
What effect does weathering have on igneous rock?
The effect of weathering is to reduce the volume of the igneous rock.
What is the effect the cause is melted rock cools?
When melted rock cools, it solidifies into igneous rock. This process can result in the formation of crystals within the rock depending on the rate at which it cools. The cooling process can also lead to the creation of different textures and structures in the igneous rock.
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 effect does weathering have on igneous rock?
The effect of weathering is to reduce the volume of the igneous rock.
The extrusive igneous rock that floats in water?
Pumice
What happens if you put a igneous rock in water?
When you put an igneous rock in water, the rock will not dissolve or change quickly. Some igneous rocks may absorb water and become slightly heavier or disintegrate over time due to weathering and erosion processes. Overall, igneous rocks are not significantly affected by water in the short term.
How is igneous rock transported?
Igneous rock is transported by wind or moving water until they are deposited in other regions where they settle in layers.
Do the words igneous rock mean water formed rock?
heck ya
How can mineral quartz be in an igneous and sedimentary rock?
== == Quartz is actually a silicate mineral that appears in metamorphic, sedimentary, and igneous rocks.
What is the effect the cause is melted rock cools?

What describes rock that was formed when molten rock cooled down?
Igneous rock is formed.
Is obsidian metamorphic igneous or sedimentary?
Obsidian is an igneous rock.
