  This exercise is about the rock (1) - erosion cycle sediment layers cemented fossils .   Start with Weathering on the web page. (See link above.)

Three types of weathering are: (2) - rubble physical gravel water biological ice wind sand chemical gravity , (3) - rubble physical gravel water biological ice wind sand chemical gravity and (4) - rubble physical gravel water biological ice wind sand chemical gravity .  Together they break rock down into a pile of  (5) - rubble physical gravel water biological ice wind sand chemical gravity ,(6) - rubble physical gravel water biological ice wind sand chemical gravity and (7) - rubble physical gravel water biological ice wind sand chemical gravity .

   The movement of small rock particles is called (8) - erosion cycle sediment layers cemented fossils . There are four major ways this can occur: by (9) - rubble physical gravel water biological ice wind sand chemical gravity , by (10) - rubble physical gravel water biological ice wind sand chemical gravity , by (11) - rubble physical gravel water biological ice wind sand chemical gravity and by (12) - rubble physical gravel water biological ice wind sand chemical gravity .

   When rivers, wind or glaciers drop their particles in a process called (13) - compaction pressure extrusion cementation deposition melt temperature , they form layers of (14) - erosion cycle sediment layers cemented fossils . 

   After two processes -- (15) - compaction pressure extrusion cementation deposition melt temperature and (16) - compaction pressure extrusion cementation deposition melt temperature , the sediments are now changed into sedimentary rock.  All sedimentary rocks:

1. Are formed from (17) - erosion cycle sediment layers cemented fossils of sediment.

2. Are grains of sediment (18) - erosion cycle sediment layers cemented fossils together.

3. May contain (19) - erosion cycle sediment layers cemented fossils .

  Metamorphic rocks have been changed by extreme (20) - compaction pressure extrusion cementation deposition melt temperature and (21) - compaction pressure extrusion cementation deposition melt temperature . For example, Limestone can change into (22) - marble basalt granite slate pumice gabbro gneiss , shale and mudstones turn into (23) - marble basalt granite slate pumice gabbro gneiss , and igneous rocks like granite can turn into (24) - marble basalt granite slate pumice gabbro gneiss .

   Deep inside the earth, rocks can begin to (25) - compaction pressure extrusion cementation deposition melt temperature because of the heat.

   In the process of  (26) - compaction pressure extrusion cementation deposition melt temperature , magma pushes through the surface of the earth and flows as lava. Two examples of extrusive igneous rocks are (27) - marble basalt granite slate pumice gabbro gneiss and (28) - marble basalt granite slate pumice gabbro gneiss . These types of rock are fine (29) - grained crystals uplift bubbles intrusive and often contain (30) - grained crystals uplift bubbles intrusive .

   If magma cools slowly inside the earth, then it forms (31) - grained crystals uplift bubbles intrusive igneous rock such as (32) - marble basalt granite slate pumice gabbro gneiss or (33) - marble basalt granite slate pumice gabbro gneiss .  These types of rock are large-(34) - grained crystals uplift bubbles intrusive and made up of interlocking (35) - grained crystals uplift bubbles intrusive .  They too can be exposed eventually at the surface through forces of (36) - grained crystals uplift bubbles intrusive , and begin the process of weathering all over again.
