They form in essentially the same way, the only real difference being in composition. They form as magma slowly cools deep underground, allowing large crystals to form. Granite forms from magma that is rich in silica, sodium, and potassium. Diorite forms from magma that has somewhat less silica and more iron, calcium, and magnesium.

What is a type of igneous rock that forms visible crystals?
Granite, gabbro, and diorite are a few igneous rocks that forms crystals. Igneous rocks that form visible crystals are intrusive igneous rocks, rocks that form under the earth's surface.
When igneous rocks from a volcanic eruption cools what does it form?
When igneous rocks from a volcanic eruption cool, they can form either intrusive or extrusive rocks. Intrusive igneous rocks form when magma cools slowly beneath the Earth's surface, resulting in larger mineral grains. Examples include granite and diorite. Extrusive igneous rocks form when lava cools quickly on the Earth's surface, resulting in smaller mineral grains. Examples include basalt and pumice.
What igneous rocks that form from magna cools slowly?
Intrusive igneous rocks, like granite.
What are rocks that form when lava hardens?
Igneous, examples include Granite and Basalt
What are rocks that form as a resutlt of cooling magma?
Intrusive or extrusive igneous rocks, such as granite and basalt.

What Igneous rocks can form?
granite and many other rocks

What igneous rock forms from granite?
Granite is already an igneous rock. If the granite simply melts and re-solidifies it will become granite again. If it melts and is erupted from a volcano, it will form rhyolite. If it melts and mixes with magma of a different composition, then it could form any number of igneous rocks.
What is granite in sedimentary form?
No, it's not a sedimentary rock, it is an igneous rock. :)
What are the main two types of igneous rocks?
Igneous rocks are classified as either extrusive or intrusive. Extrusive rocks form from lava at or above the ground, and intrusive rocks form from magma below the ground. Granite is intrusive, pumice is extrusive.
How do igneous rocks like granite form?
Igneous form when molten rock cools and solidifies. Granite is an intrusive igneous rock, meaning it forms when molten rock cools deep underground. There are also extrusive igneous rocks, which cool on the surface after erupting from a volcano.
Forms when magma cools within earth?
Volcanic neck.
What type of rocks form from melting and cooling?
These are igneous rocks. They may form from lava at the Earth's surface, like basalt, or from magma beneath the ground, like granite.
