| Metamorphic rock can be divided into two categories | Foliated (minerals flattened in layers) and non foliated (not banded) |
| Metamorphic rock | Rock that is changes forms due to extreme temperature and pressure |
| Lava | Molten material (mineral soup) that solidifies at the surface of the earth |

| Examples of igneous rock | Granite (contain mineral quartz and feldspar) pumice, obsidian, basalt, gabbro |
| How do you Change and igneous rock to a metamorphic rock in the Rock cycle? | Heat and pressure |
| How do you change a metamorphic rock to sedimentary | Weathering and erosion then creates sediments then the cede nets cement and compact together |
| How do you change a sedimentary rock to to metamorphic rock to igneous | Melting magma or lava then solidification and crystalization |
| In which nys landscape region is in Niagara Falls located? | Erie Ontario lowlands |
| What is the equation used to correctly calculate the air pressure gradient between two locations? | Gradient = change in air pressure ( mb) / distance (km) |
| Which mineral is most frequently found in both granitic continental crust and basaltic oceanic crust? | Plagioclase feldspar |
| Which if the following landmass es is moving northward with Australia as part of the same tectonic plate? | India |
