no, it's molten rock, as in lava....
They're hard AND the float on magma.
Magma is underground, when it reaches the surface it becomes lava. So solidified magma is really lava. The lava flow is the liquid lava as it goes down the mountain, when hard its just hardened lava. Magma is underground, when it reaches the surface it becomes lava. So solidified magma is really lava. The lava flow is the liquid lava as it goes down the mountain, when hard its just hardened lava.
When magma crystallizes, igneous rocks are formed. The type of igneous rock that is formed depends on the chemical composition of the magma and the rate at which it cools.
It is just the hard sort. Most hard rock was constructed by slow solidification of magma but some metamorphosed sedimentary and igneous rocks can also be considered to be 'hard rock'. And most igneous rocks except volcanic ejecta are hard. But to a geologist a hard rock usually means a slowly solidified magma in which minerals had time enough to form visible crystals.
their are many types of magma because when a volcano has soft magma that means it either exploded small or the magma was going really slow and fast magma and big exploding volcano's are hard magma.:)
magma or lava.

the crust is hard liquid magma (lava)
no it is made up of lava and magma and also has volcano
well in volcanoes is magma, which when it is no longer in the volcano, is lava. and when a volcano is explosive, in the magma is silica. and silica makes the magma really sticky and thick. in a volcano, the magma comes out of vents at the top. and when magma with silica tries to comes out, it gunks up the vents to where they are clogged and nothing can get out of them. so when this happens, pressures pushes hard to try and get the magma out. then it pushes REALLY hard and it comes out even bigger and destructively! but when there is no silica in the magma, the magma just drizzles out of a volcano but its nonexplosive. hope this helps. and i know this is true. we just learned it in science class. I'm 11 years old but i am certain this is the correct accusation.

Some are produced by the eruption of magma (eg volcanoes), others are produced after the magma has cooled to rock. As magmatic rocks are usually hard they resist erosion and cause features such as Arthur's seat or escarpments. Granitic magma gives rise to Tors (such as those on Dartmoor or the Seyshells)
An acid magma or a granitic magma.
The mantel made of partially molten rock which is commonly known as magma. The top layer of the mantle is usually hard.
