They are hard, they are crystalline, they are generally non-stratified, and they do not contain fossils.

Igneous rocks are formed from the solidification of molten material (magma or lava) and typically have a crystalline texture. They can be classified as intrusive (formed below Earth's surface) or extrusive (formed on the surface). Igneous rocks often have interlocking mineral crystals and may contain gas bubbles or vesicles.

What form's with physical properties with Extrisive?
Extrusive rocks are igneous rocks that form as a result of crystallization of magma at Earth surface
What are a basic list of the physical properties of igneous rocks?
Some basic physical properties of igneous rocks include color, texture (such as grain size and shape), density, hardness, and composition (mineral content). Additionally, features like porosity, cleavage, fracture, and luster can help further describe and classify igneous rocks.
What are igneous rocks that form over the surface?
Rhyolititcen rocks.
What do you call rocks that have been formed from the hot molten material within the earth's crust that has cooled and hardened?
Igneous rocks are formed by the solidification of molten materials.
Are igneous rocks made up of igneous rocks?
No, igneous rocks are formed from the cooling and solidification of magma or lava. They are not made up of pre-existing igneous rocks.
When molten rocks cools what rocks form?
igneous rocks

Are volcanic rocks igneous rocks?
Yes. Volcanic rocks are extrusive igneous rocks.
Why are igneous are called primary rocks?
Igneous rocks
Are sedimentary rocks are harder than igneous rocks?
No, igneous rocks are harder than sedimentary rocks on average.
What are 7 elements igneous rock contains?
The seven main elements commonly found in igneous rocks are silicon, oxygen, aluminum, iron, calcium, sodium, and potassium. These elements make up the minerals that compose igneous rocks and give them their characteristic properties.
How do fine- grained igneous rocks from?
extrusive igneous rocks =/
What kind of igneous rocks for on earths surface?
Some do. These are called extrusive igneous rocks. However a large portion of igneous rocks form beneath the surface. These are intrusive igneous rocks.
