Please! I cant find these answers on rocks and minerials!?

Question

here are the questions:

1. What are 3 minerials that make up sediments?
2. What are 3 ways sedimenttary rocks can form? And their definition?
3. What are 3 classifaction of sedimentary rocks? (and examples of each)

Thoes are the major ones but here are a few more....
(I am looking for tese right now so you dont need 2 answer them, if you just know, please tell me:)
THESE ARE ALL QUESTIONS ABOUT IGNEOUS ROCKS:)(:

1. Igneous rocks that are dense and dark-colored. they form from magma that is rich with iron/magnesium and poor in silica?
2. light colored and have a lower density. They form from thick, stiff magma that contains lots of silia and lesser amounts of iron/magnesium
3.Igneous rocks that have minerial compositions between thoes of granitic/basaltic rocks
5.One kind of volicanic glass that has holes, caused by pockets of gas
6.The kind of igneous rock that forms below Earth's surface
7. igneous rock that froms in/near the earths surface

THANK YOU!!!!!!!!!!

Answer 1

go www.wikpedia.org and write sedimantru, igneaos and metamorphic rocks sepratly or go to www.thirteen.org to watch movies about rocks and minerals

Answer 2

I'll get the seds then:

1. Silica, CaCO3 (shell fragments and matrix), Feldspar - some of the common ones.
2. Ways sedimentary rocks can form? Well, they're pretty much all erosion/deposition. Not sure what question criteria are... Aerial = wind-blown (i.e. Loess). Marine = current deposited (i.e. Greywacke - meta-sandstone). Gravity flow = conglomerate.
3. Classifications of sedimentary rocks? Can be classified by dominant mineral (e.g. quartz - quartz sand or quartzite, grain size (e.g. silt sized - siltstone, mudstone, argillite), or environment of deposition (e.g. terrestrial, marine, lacustrine - lacustrine clay)...

Answer 3

I know the igneous ones but not the sedimentary.

1. mafic rocks
2. felsic rocks
3. diorite and andesite
5. vesicular basaltic glass
6. intrusive rock
7. extrusive rock

Answer 4

I had a puppy rock decrease back in 1974. regrettably it replaced into run over by a truck. It replaced into in no way fairly the comparable after that and it finally crumbled into sand. We sprinkled the continues to be over the river. Oh, I nevertheless pass over my puppy rock. It in no way had a wager to fulfill that distinctive somebody!
