Across
- 2. a phanitic extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron exposed
- 6. formed from pre-existing rocks or pieces of once-living organisms.
- 10. large mass of intrusive igneous rock, larger than 100 km² in area, that forms from cooled magma deep in Earth's crust.
- 11. form when hot, molten rock crystallizes and solidifies
Down
- 1. fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of clay minerals and tiny fragments of other mineral
- 3. whole formed by combining several (typically disparate) elements.
- 4. are composed of fragments, or clasts, of pre-existing minerals and rock
- 5. the solid mineral material forming part of the surface of the earth and other similar planets, exposed on the surface or underlying the soil or oceans.
- 7. clastic sedimentary rock that is composed of a substantial fraction of rounded to subangular gravel-size clasts
- 8. started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary
- 9. phaneritic, mafic intrusive igneous rock formed from the slow cooling of magnesium-rich and iron-rich magma into a holocrystalline mass deep beneath the Earth's surface
