Does anyone know anything about Earth Science???"?

Question

I have a test in Earth Science tomorrow and i need help plzz..its on different rock types

Answer 1

Rocks
Rocks and minerals are the source of almost every material that is produced on the Earth. Most objects that we commonly use today originate from a rocks or minerals source. Without the mining of coal, humans would not be able to fuel machinery to produce many of the products that are used today in society. Rocks and minerals also provide the raw materials necessary to build homes or any other construction project. In fact, the mineral gypsum is the main material in sheet rock, which is widely used as the wall structure for most new construction.
The solid portion of the Earth's crust, the lithosphere, is composed of naturally occurring materials made up of one or more minerals, called rock. All rocks are composed of minerals.

different rock types form from one another.

(;Sedimentary rock
(:Sediments
(:Igneous rock
(:Medamorphic rock
(:Magma

Minerals
Minerals are the building blocks for all rocks. Minerals are naturally occurring, inorganic, crystalline, solid materials with definite chemical composition, molecular structure, and certain physical properties. Of the more than 2000 minerals on Earth, about a dozen of them make up about 90% of the Earth's crust.

Identifying Rocks and Minerals
Many students have trouble with the identification of rocks and minerals.

Answer 2

Different rock types huh...well let me see if this helps. Their are essentially three main classifications of rocks; sedimentary, igneous and metamorphic. Sedimentary rocks are formed from accumulated sediment(such as sandstone, shale, even coal) Sediment comes from the erosion of other rocks. Igneous rocks are produced from volcanic activity, whether it be through a volcano or inside the earth. Lava(magma when it is underground) can be made of different minerals and can cool at different rates producing different rocks. These rocks are igneous. Examples would be basalt, granite, rhyolite,.... Metamorhpic rocks are a result of heat and/or pressure. You start off with either a sedimentary or igneous rock and you apply heat and/or pressure to it to change it into a different rock. The new rock that is formed is a metamorhpic rock. The type of metamorphic rock depends on how much heat and/or pressure was applied. Hopfully this helps. Email me at [e-mail] if you have more questions.

Answer 3

Earth science (also known as geoscience, the geosciences or the Earth Sciences), is an all-embracing term for the sciences related to the planet Earth. It is arguably a special case in planetary science, being the only known life-bearing planet. There are both reductionist and holistic approaches to Earth science.

Answer 4

Composition & Internal Structure of the Earth

Any group of diverse materials can be classified by chemistry or physical properties. Chemistry refers to different materials, and physical properties refers to such things as whether the materials are solids or liquids, etc. Some physical layers in the earth consist of 2 chemical layers and some chemical layers consist of 2 physical layers.

Compositional/Chemical Layering

The chemical layering of the earth formed as part of the earth's differentiation-resulting from the heat generated during the process of planetary accretion. As a general rule, denser materials settled to the center of the earth, leaving lighter materials on top. Thus, the earth consists of successive layers of material getting less dense as you approach the surface. The major compositional layers are:

Core is made of iron with minor amounts of nickel, and lies at the center of the earth
Mantle is made of iron-magnesium silicates and surrounds the core. The mantle m

Answer 5

Wouldn't it be time to hit the books now?

Oh, all right! Here goes.
Gone Soft rock: Rod Stewart
Hard rock: Metallica
Old rock: Bill Haley and the Comets
Real rock: Jimmi Hendrix
Alternative rock: (insert name)

Well that's about it for now. Good luck.=)

Answer 6

you no i just finished studing that, theres igneus,metemorphic,and sedementary rocks.there is a rock cycle that turns those rocks into another rock..its igneus to metemophic to sedementary rocks.if that helps any?

Answer 7

You have access to the internet! Search "rock types" and study what you come up with!!

DO YOUR OWN HOMEWORK!!!!

Answer 8

additionally, Tardigrades are in basic terms approximately indestructable. they are able to stay to tell the story in area for 10 days w/out food or water, they are able to stay to tell the story interior a volcano or in Antartica, very practically indestructible.

Answer 9

yes i know !! i am studying geology .. does this help ??? i dont think so ... if you have some specific problems ask about them .. otherwise its difficult to me to help !! maybe its late but the following web sites may help !!! good luck ..
