How can you get different igneous rocks from the same magma body?
Magma underground may differentiate and form different intrusive igneous rock. Magma from the magma body may erupt, cool, quickly, and form fine-grained extrusive igneous rock, or partially remain underground and form intrusive igneous rock. The type of igneous rock formed from the magma body will largely depend on whether or not it is erupted, and the speed of its cooling.
Are all igneous rocks formed the same way?
No. All rocks can become other rocks by the processes of erosion and metamorphism. An igneous rock may become eroded into its constituent mineral grains such as quartz and feldspar, which are transported by wind and water, eventually settling to form a sedimentary rock. An igneous rock may become buried by tectonic movement and sediment, where heat and pressure cause it to recrystallise into a metamorphic rock, and or melt and resolidify into another type of igneous rock. Also in the rock cycle it can become sediment, metamorphic rock or melt again
Is lava a sedimentary rock or igneous?
The common usage of "lava rock" in the USA refers to a black rock with a number of visible bubbles or air pockets that is formed from cooled lava on the surface. Although lava rock is an igneous rock, it is not the same as the definition for the word igneous, which can also include igneous rocks which have solidified from magma below the surface.
Are the diamonds formed the same way as igneous rocks?
No. Igneous rock is formed from the solidification of magma or lava. Diamond is a mineral which is formed at great depth below the surface, from intense pressure and heat.
What is the change of state when magma crystallizes to form ingeous rock?
It is according to what kind of material the lava is made from. If there are different minerals in the lava, then it is according to what temperature the mineral returns to the solid state, or a rock. Some minerals have a liquid temperature, close to the liquid temperature of another minerals, and chances are they will form in the same rock. Temperature determines what the rocks will become. Like gold is found in quartz. Their liquid temperatures are close so they form together.
What intrusive igneous rock has the same mineral composition as basalt?
Gabbro is an intrusive igneous rock that has the same mineral composition as basalt. Both rocks are composed primarily of plagioclase feldspar and pyroxene minerals.

How do two igneous rocks have the same mineral composition but different textures?
The texture of an igneous rock refers to the size of its mineral crystals. If the common magma of both igneous rocks has experienced differences in cooling rates due to depth, they will have different textures. Slow cooling produces large crystals, and quick cooling produces small crystals. Granite and rhyolite are two igneous rocks sharing the same mineral composition, but having undergone different rates of magma cooling due to depth at solidification.
What igneous rock would form from magma if it did not reach the surface but instead crystallized?
Intrusive igneous rock would form. Granite is an example. If the same magma that formed the granite had reached the surface through volcanic eruption, the extrusive igneous rock rhyolite would form.
Which rocks has two different size grains of the same mineral?
Pegmatite is a type of igneous rock that can have two different grain sizes of the same mineral present. This is due to the slow cooling process of the magma, allowing for the growth of large crystals (phenocrysts) within a finer-grained matrix.

Which feature in a rock layer is older than the rock layer?
mineral veins.. I think it may be rock fragments as well though depending one what kind of rock.. Mineral veins will work with metamorphic and igneous rock. It may also work for sedimentary rocks.. I had the same question btw
What is the composition of ocean crust?
It is mostly composed of basalt, and few other mineral types. It is made mostly of igneous rock, same with continental crust.
Do all igneous rooks have the same mineral compositions?
yes
How does igneous rocks form?
Igneous rocks forms when molten rock cools&becomes solid. Igneous rocks that originally formed at great depths can reach Earth's surface over time. Deep rocks may be raised closer to the surface when mountains are pushed up.At the same time , other process can wear away the rocks that cover the deeper rocks
