How do igneous rocks form?
Igneous rock forms from the cooling of molten material called magma or lava.
Why aren't igneous rocks affected by lava?
Igneous rocks aren't affected by lava because they are made of cooled lava.
What type of rocks form from lava after a volcanic eruption?
Igneous rocks are formed from the cooling and solidifying of magma. The resulting rock can be instrusive (magma cooling within the crust) and extrusive (lava cooling on the surface). The most common kind of rocks are Granite (intrusive) and Basalt (extrusive).
What does igneous rocks mean?
Igneous rocks are rocks that have been formed from the cooling of flowing magma from a volcano or crack in the earth with lava beneath it. Igenous may or may not form crystals in there composition, and most of the rocks are from the mantle or the lower crust.
Do we have igneous rock in Nigeria?
No we do not have igneous rocks in Nigeria because there are no volcanoes in Nigeria and it is lava or magma that make igneous rocks.
What are rocks that form when lava hardens?

What are rocks that form from the cool lava?
Igneous rocks.
Igneous rocks that form when lava cools under the crust?
Intrusive igneous rocks do this.
What is a large group of rocks which form magma or lava?

How do igneous rocks form?

How do igneous rocks form at hot spots?
The lava volcanoe shoots the igneous rocks out of it and then it farts hot spots
What extrusive thing does igneous rocks form?
Magma or Lava
What Extrusive igneous rocks form when hardens and cools.?
lava
Igneous rock form on eath surface?
Igneous rocks do form on the earths surface. A volcano erupts and the lava that comes out cools and hardens forming igneous rocks.
How are volcanoes important in the formation of rocks?
Because the lava from volcanoes form igneous rocks
How are rocks that form from magma and lava different?
They are different because lava is when it hits earth's atmosphere; magma turns to lava. Magma is when its inside the volcano. They are different because of the color: darker/blacker and magma rocks are way hotter. Lava rocks are colder and fragile.
What class or rocks are made from lava or magma?
Rocks made from lava or magma are classified as igneous rocks. Igneous rocks form when molten rock cools and solidifies, either on the Earth's surface (extrusive) as lava or below the surface (intrusive) as magma. Examples of igneous rocks include basalt, granite, and obsidian.
