Basalt.
They are called extrusive rocks. Extrusive igneous rocks are formed on the earth's surface by the cooling of magma or lava. Intrusive igneous rocks are also made of the cooling of magma or lava, but it cools inside the earth. I hope this is the information you were looking for.
naturaly rocks are made up of any natural mass of mineral matter that makes up the earth'scrust . rocks can be of different colour,size and texture. the interior plane is made up of intrusive and extusive rocks
Extrusive igneous rocks form when magma erupts as lava above Earth's surface. The resulting lava cools rapidly on Earth's surface. As a result, minerals do not have time to form. An example of an extrusive igneous rock is pumice.
No. Igneous rocks were NOT formed in layers. I took a test and they are not formed in layers. This is what the paragraph said {The Word "igneous" means made from fire or heat. All igneous rocks have been formed by heat. Deep in the earth it is very hot. The rocks and minerals there have been changed into molten rock called "magma". This hot material sometimes rises to the earths surface through fissures or cracks caused by earthquakes, volcanoes or other deep movements of the earth's crust. Igneous rocks are formed when magma cools and hardens. Scientists divide igneous rocks into two group. They are called "extrusive" rocks and "intrusive" rocks. When magma hardens below the suface of the earth, surrounded by older rocks which it has invaded, the rock is called "intusive" igeous rock. If magma reaches the surface of the earth, however, it becomes lava, and the rock is called "extusive" igneous rock. Lava is a common igneous rock. The namelava can mean molten rock or cool hard rock. The two most common and important igneous rocks are granite and basalt. Some others are diorite, felsite, pumice and obsidian.} thank you! that was fun, and your welcome. bye!
