Igneous rocks

Click this web LINK for questions #2-#9 :

Igneous rocks are formed from molten magma or lava. The word, igneous means "fire". All igneous rock starts deep in the earth as hot, molten magma. If the magma cools and hardens inside the earth it is called
"intrusive" rock. These rocks cool slowly andhave large crystals. When the magma comes out of the earth's crust through a volcano, it is called "extrusive".If It cools off quickly, the crystals that form are very small and if it cools slowly the crystals are larger. Molten, or hot, liquid rock is called MAGMA when it is still inside the earth, but once it comes out through a volcano it is called LAVA.

2. Igneous rocks are formed from _______________ or _________________

3. The word igneous means ___________

4. If the magma cools and hardens inside the earth it is called _________________rock.

5. These rocks cool ____________ and have ____________ crystals.

6. When the magma comes out of the earth's crust through a volcano, it is called "_____________".

7. It cools off ___________, and the crystals that form are very __________.

8. Molten, or hot, liquid rock is called __________ when it is still inside the earth, but once it comes out through a volcano it is called _____________.

This LINK will help you to answer the following questions:

11. Every minute of every day, rocks are being worn down by _________ and __________.

12. Tiny grains of __________, _____________, _____________ and ____________ are worn off and washed into streams, rivers, lakes and oceans. When these tiny bits of sand and dirt settle to the bottom of the water, they are called ___________.

13. _______________ in the water and microscopic, or very tiny sea animals also get mixed in with the dirt and sand to form the sediment.

14. Every day more sediment _________ on top of what is already there.

15. After thousands and ____________ of years we end up with a really deep pile of sediment.

16. The ____________ and _____________ from all the stuff on top turns the sediment on the bottom into sedimentary rock!

Metamorphic rock: Click HERE to help you answer questions #18-25

Metamorphic rocks are formed when other kinds of rocks are changed by great heat and pressure inside the earth. The word "metamorphic" means CHANGED. Think of metamorphic rocks as recycled rocks. When igneous, sedimentary or even metamorphic rocks get buried deep beneath the surface of the earth, over millions of years the heat and Pressure inside the earth change them into something else.They contain distorted crystals. Limestone can be changed to marble, sandstone can be changed into quartzite, and shale can be changed to slate. It's just another example of how the earth is constantly changing!

18. Metamorphic rocks are formed when other kinds of rocks are changed by great _________ and _____________ inside the earth.

19. The word "metamorphic" means _______________.

20. Think of metamorphic rocks as ________________ rocks.

21. When _____________, __________________ or even __________________ rocks get buried deep beneath the surface of the earth, over millions of years the heat and pressure inside the earth change them into something else.

22. Limestone can be changed to ______________,

23. Sandstone can be changed into ________________

24. Shale can be changed to __________________.

29. What are 9 properties that can be used to identify minerals? Click HERE

C______________ Keep in mind, however, that ________ by itself isn't enough to identify a mineral. Chemical impurities can __________ the color of a mineral without changing its basic make-up
S______________ When a mineral is rubbed firmly across an unglazed tile of white porcelain (a streak plate), it leaves a line of powder. This is called the __________
T______________ _________________ describes how well light passes through a mineral sample. There are three degrees of transparency: _________________, ______________, and _______________
L_______________

___________ is the way the surface of a mineral reflects lightThere are two general types of luster -- ___________ and ____________. Other terms used to describe luster are:

 

H_______________ The hardness scale was established by _________________ _______. The Mohs’ hardness scale places ten common or well-known minerals on a scale from one to ten. One is the ________ mineral and ten is the _______________.
C_______________ When a mineral sample is broken with a hammer, it breaks along planes of weakness that are part of its crystalline structure. Sometimes along smooth surfaces
F________________ Not all minerals cleave easily. Some ___________ instead. Unlike cleavages, which are usually clean, flat breaks, fractures can be curved, irregular, jagged or splintery.

S______________

G______________

 

Specific gravity is the ________________ of a mineral

C__________

F___________

Minerals grow in specific shapes, and usually crystallize into one of six crystal systems
