Rock Cycle Notes Cloze:

1.   ________________ are naturally occurring, inorganic solids with a definite chemical composition and a crystal structure.

2.   rocks are made of________________.

3.   rocks are mixtures of one or more minerals , rock fragments, volcanic glass, organic matter, or other natural materials.

4.   ________________-process where rocks slowly change from one form to another through time.  Any type of rock can change into any other type of rock.

5.   ________________-means to wear down, ________________ is the carrying away, and ________________ is dropping it as sediment

6.   3 types of rocks are ________________, ________________, and sedimentary


9.  ________________ rock is made up of fragments of other rocks that have been broken down by weathering.

sd ed

10.________________ rock is made from rocks that have been heated and squeezed by the tremendous pressure inside the Earth.

rglimestone changes into this, marble yt

  

11. ________________ rock is formed when any type of rock gets melted by the incredible heat inside the Earth.

ry

Igneous Rocks:

12. igneous rocks are formed when________________ or________________ cools and hardens.

13. magma that reaches the Earth’s surface is called lava

14. ________________-igneous rocks that form from magma________________ the Earth.  They form “IN” the Earth-Intrusive.

15.  intrusive rocks have________________ grains because the magma cools very ________________.  The slower the cooling, the________________ the grains

uj

16. ________________ and ________________ are the same thing

17. ________________-extrusive rocks are formed from lava cooling on the surface of the Earth.  Extrusive rocks cool ________________ causing small grains. The________________the cooling process, the ________________the grains.

7u

18.  volcanic glass, such as pumice, obsidian, and scoria cooled so fast that they don’t have grains or crystals.

20.  basalt and granite are________________ rocks

Metamorphic Rocks:

21.  ________________rocks have been changed by________________ and________________.

22.________________ rocks can be formed from igneous, sedimentary, or other metamorphic rocks.

23.  high temperatures inside the Earth cause the rocks to________________ without actually melting.

24.________________ rocks have their grains (crystals) arranged in layers.  (think“folded” like towels)

6y

25.  slate and gneiss are foliated ________________ rocks

26. ________________ rocks do not have layers.  Quartzite and marble are________________ metamorphic rocks.

5g

Sedimentary Rocks:

27.________________ are loose materials such as rock fragments, mineral grains, and bits of shell that have been moved by wind, water, ice, or gravity.

28. ________________ rocks are formed when sediments are pressed and cemented together or when crystals form from solutions.

29. ________________ and ________________- is what forms the sediment into sedimentary rocks.  The tiny particles are pressed together and then cemented by minerals.

30.  sedimentary rocks often form as________________.  The________________ layers are on the________________ and the newest layers are on the top

31.  fossils are ONLY found in________________ rocks

34. ________________ sedimentary rocks are cemented together

uj yt

35.  sandstone and shale are________________ rocks

36.________________ sedimentary rocks are formed when________________ chemicals in solutions, such as salt in seawater, form rocks such as halite and________________.

yu

37. ________________ sedimentary rocks are made of the remains of ________________ things, usually shellfish such as clams, corals, and snails. ________________ is an example of organic sedimentary rock.

uj1

38.  coal is an ________________ sedimentary rock formed from the remains of dead plants that have been chemically changed and cemented together.
