∙ 10y agobecause if you scramble igneous,its close to genious, which is close enough to genius if you ask me, so they were smart enough to become rocks

intrusive igneous rock
How do geologists classify igneous rock?
Geologists classify rocks by where they are formed; above ground or under ground
Is igneous rock generally soft or hard rock?

Why do geologists say that all rock was originally igneous rock?
It is because all rocks started out as liquidawere once all very,very,very hot liquids.Also,rocks are made of minerals,and minerals are made from lava or magma
Who studies igneous rock?
Geologists study the rocks that compose the earth or other terrestrial planets. Mineralogists classify and name types of lava. Stone cutters study granite , which is an igneous rock.
Why do igneous rocks stick up above the ground?
Softer rock is originally around the igneous rock but the soft rock has eroded making the igneous rock visible and above ground level.
Describe granite using the three characteristics geologists use to classify igneous rocks?

How is an igneous rock created?
Igneous rocks are created when magma cools into a solid state.
What are the terms felsic and mafic used by geologists to describe?
They are descriptive terms as to the relative silica content of igneous rocks. Igneous rock which is high in silica is referred to as felsic. Igneous rock which is relatively low in silica is referred to as mafic.
Sometimes metamorphic rock is found adjacent to an igneous intrusion as shown in the drawing According to geologists what causes this phenomenon?
The surrounding rock was metamorphosed when it came into contact with the hot magma
Is molten a igneous rock?
It depends as to what type of rock the volcano is made of or whether other rocks have gone into the volcano because magma or molten rock is liquid rock which when hardened I suppose yes would then be classed an Igneous rock because it was formed by being heated, melted, cooled and reformed again. However some geologists argue that it should be a form of its own but has it undergoes the process used to form Igneous rocks it should really be classed as an Igneous rock
Who studied rock?
