What are some similarities and differences in the way in which these rocks formed igneous vs. sedimentary

Igneous is formed by cooled magma (molten rock) and Sedimentary is formed  by wear and tear of the earth (erosion).

Igneous rocks and Sedimentary rocks both are both created under very hot temperature.

Igneous rocks are formed by the cooling of magma(molten rock) inside the Earth or on the surface while Sedimentary rocks are formed from the products of weathering by cementation or precipitation on the Earth's surface.

very interesting question. i'm a guy, so my vote hardly matters, but blue according to my wife is a purple with more blue than red.

the "brown"   is not mauve. that's the tough one. it has more brown the mauve in it. you almost need a color wheel to tell or a paint sample book. her gloves are a deeper purple.

i would also qualify this by saying you need say how good your monitor is. i'm working with a lap top so i couldn't swear by anything i've written is accurate. i had 3 women offer an opinion. they were not in agreement and they were not certain.

for posting. i'm more of a math type so i'm staying out of this but it was lots of fun.
