And ill with a math/english question im good at those what are some specific rocks found in grand canyon (for example, the tapeats sandstone)? name and describe at least 3 examples in at least 3 sentences each. be sure to indicate whether each rock is sedimentary, metamorphic or igneous. you can also mention the age of the rock, how it was formed/deposited, where it is found in the canyon with respect to other rocks, colors, grain/crystal sizes, types of minerals found within the rock, cross-bedding features, clasts, fossils present, banding/layering, geometric orientation (angle), etc. (9 points) rock 1 full name (ex: tapeats sandstone): rock type (igneous? metamorphic? sedimentary? ): description (3 sentences or more): rock 2 full name: rock type: description: rock 3 full name: rock type: description:

Rock type: Igneous?

They form from the cooling of magma deep inside the earth. They often have large crystals you see them with the naked eye. Are formed when rock is super-heated and becomes molten liquid. There are two kinds of molten rock magma found beneath the earth’s surface and lava found on earth’s surface.

The molten rock cools and hardness on or beneath the earth’s surface forming a variety of igneous rock two type of rock are called the granite rock and the other is called the basalt rock. Metamorphic? They are formed through the change of igneous and sedimentary rocks. They can form both underground and at the surface. Are rocks that have been changed under great heat and pressure.

The original rock can be sedimentary, igneous or even metamorphic the original rock is changed into something new, just as a caterpillar metamorphic into a butterfly. Sedimentary?): they are formed through the solidification of sediment. They can be formed from organic remains such as limestone or from the cementing of other rocks.

Are made of smaller pieces like sand or mud, called sediments that pile into layers as pressure on the sediment increases over time minerals are like glue cementing them into solid rocks. Sandstone, limestone, shale, mudstone. Description (3 sentences or more): Chart is a microcrystalline or cryptocrystalline sedimentary rock material composed of silicon dioxide coal is an organic sedimentary rock that forms mainly from plant debris. Rock

2Full Name: Genesis Rock type:

High temperature and high pressure metamorphic processes acting on formations composed of igneous or sedimentary rocks. Description: it is characterized by alternating light and dark bands differing in mineral composition coarser grained than schist. Rock 3

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
