Quartz and Feldspar will be comparatively larger in size since they are formed from cooling of magma while Pyroxene and Olivine are formed by the cooling of lava.

What is the difference between magma and Lava?

Magma is molten rock that is found deep within the earth's crust whereas Lava is molten rocks that comes up and flows on the earth's surface.

Minerals formed from magma and lava have comparatively different sizes.

Minerals formed from magma are larger in size than minerals formed from Lava. This is because minerals formed from magma undergo slower cooling, and thus, have a longer time to grow in size. However, minerals formed from lava have a relatively shorter cooling time and do not grow into very large sizes.

Therefore, Quartz and Feldspar will be comparatively larger in size since they are formed from cooling of magma while Pyroxene and Olivine are formed by the cooling of lava.
