What made up the igneous rock?

Answer 1

Igneous rocks can be made of mineral crystals of quartz, feldspar, micas, olivine, amphibole, pyroxene, hornblende, and elements like iron, manganese, calcium, magnesium, silicon, copper, lead, carbon, oxygen, sulfur, hydrogen, and other kinds of rocks

Answer 2

Igneous means made from fire or heat.

When volcanoes erupt and the liquid rock comes up to the earth's surface, then new igneous rock is made.

When the rock is liquid & inside the earth, it is called magma.

When the magma gets hard inside the crust, it turns into granite.

Most mountains are made of granite. It cools very slowly and is very hard.

When the magma gets up to the surface and flows out, like what happens when a volcano erupts,

then the liquid is called lava.

Lava flows down the sides of the volcano.

When it cools & turns hard it is called obsidian,lava rock or pumice - depending on what it looks like.

• Igneous rocks form when molten lava (magma) cools and turn to solid rock.

  The magma comes from the Earth's core which is molten rock .

  The core makes up about 30% of the Total Earth Mass (31.5%)

• Obsidian is nature's glass. It forms when lava cools quickly on the surface. It is glassy and smooth.
• Pumice is full of air pockets that were trapped when the lava cooled when it frothed out onto the surface.

  It is the only rock that floats.

• There are 5 kinds of igneous rocks, depending on the mix of minerals in the rocks.

• Granite contains quartz, feldspar & mica
• Diorite contains feldspar & one or more dark mineral. Feldspar is dominant.
• Gabbro contains feldspar & one or more dark mineral. The dark minerals are dominant.
• Periodotite contains iron and is black or dark.
• Pegmatite is a coarse-grained granite with large crystals of quartz, feldspar and mica.

Answer 3

Igneous rock is one of the three main rock types based on the method of its formation. It is also referred to as plutonic or volcanic rock depending on where it formed. In a nutshell, to be classified as igneous, a rock must have crystallized and solidified from molten rock (magma) either below ground (intrusive igneous rock) or at or near the surface (extrusive igneous rock).

Answer 4

Igneous rock is formed from the solidification of molten material called magma or lava. This process occurs deep within the Earth's crust or at the surface during volcanic eruptions. The composition and texture of the rock depend on the cooling rate and mineral content of the magma.

Answer 5

Sollidified hot molten rock fluid called Magma, which is composed of minerals, ions, molecules, compounds, and atoms.

Answer 6

they are made up of molten rocks
