4th SW #5 Rocks
1.  Rocks are classified as:   
Sandstone, Slate, Obsidian
Hard, shiny, grey
Sedimentary, Metamorphic, Igneous
Sedimentary, marble, Igneous Basalt
2.
Choose the correct statement about rocks.
Igneous rocks form when magma cools 
    and hardens.
Fossils can be found in Igneous and metamorphic
    rock. Not usually in sedimentary rock.
You can often see sand, pebbles or stones 
     present in Metamorphic rocks.
All rocks are hard, grey, and form the same way.
3.Which of the following are all classified as Igneousrocks? (look at journal p.74)
Obsidian, Granite, Scoria
Conglomerate, Sandstone, Shale
Granite, Sandstone, Quartzite
Slate, Gneiss, Marble
4.The process in which water, wind and ice weardown rocks and other surfaces is called:
Erosion
wearation
weathering
deposition
5.The process where sediments are reduced in volume and are pressed and squeezed into layersis called:
pressure packing
cementation
squishing
compaction
6.One process by which Igneous rock can be changedinto Sedimentary rock is:
Weathering, erosion, deposition, then heat      & pressure.
Weathering, erosion, deposition, then      compaction & cementation
heat & pressure, then melting & cooling
melting, then weathering, erosion & deposition
7.Metamorphic rock can change to sediment throughthe process of:
Melting, cooling, meling & heat
Heat & pressure, then compation & cementation
Weathering, heating, melting & compaction
Weathering, erosion & deposition
8. Igneous rock can change to Metamorphic rock through the process of:
Melting and cooling
Heat & pressure, cooling & melting
Heat & pressure
All of the above
