HS2339 Week 1 Inorganic Material Structure and Properties Flashcards
1
Q
Different rock types
A
- Igneous rocks formed by volcanic ACTIVITY UNDERGROUND depends on rate of cooling
- broken down by climate, water and weathering, forms them into rock strata, sedimentary
- metamorphic, movement moves sedimentary rock strata and heat and pressure alters properties of rocks
2
Q
Stone properties (example Granite)
A
- granite is an igneous rock formed underground, mostly silicon dioxide and potassium aluminium silicates
- low porosity
- layering can occur due to underground action
- decay resistant, hard to work
3
Q
glass like igneous rocks ie obsidian
A
- cooled lava, not enough time to reorganise into crystal structures, more glass like, a supercooled liquid
- flint, amorphous structure found as deposits in sedimentary rocks, found as nodes, can be work like obsidian

5
Q
Limestone properties
A
(also dolomite)
(notice the layers and planes become evident when sedimentary rock is weathered, as rocks are varying in hardness)
(can be stained with iron impurites)
