What process is needed to make Igneous Rocks
Melting and Cooling
What is the definition of Magma?
Molten rock or melted rock
Define Sediment
Weathered down or small rock fragments of rock and soil
Deep in the earth near magma
Define Rock
A mixture of minerals, rock fragments, volcanic glass, organic matter, or other natural materials
What process makes Metamorphic Rocks?
Heat and Pressure
What's the name of the two main categories of Igneous Rocks?
Intrusive and Extrusive
Explain what makes up chalk and coal in the Organic Sedimentary Rock category
Sea Shells and Dead Plants
Define Pressure
Force exerted over a certain area
Define Lava
Magma that reaches the earth's surface
What process makes Sedimentary Rocks?
Compaction and Cemenation
Name 3 examples of Igneous Rocks
Gabbro, Basalt, Andesite, Granite, Obsidian, Pumice, etc.
Name three types of Sedimentary Rocks
Shale, Limestone, Sandstone, Chalk, Coal, etc.
List and define the two types of sedimentary rock
Foliated and Non-Foliated
Mineral grains lined up in layers and without layers
Define Deposition
When sediments settle in an area after transportation
How are sediments formed?
Weathering and Erosion
Compare and Contrast Intrusive and Extrusive (Location/Size of Crystals/Cooling)
Intrusive - In the earth, slow cooling, large crystals
Extrusive - On the earth, fast cooling, fine grain or small crystals
List the 3 Categories of Sedimentary Rocks
Detrital
Organic
Chemical
Name three types of Metamorphic Rocks
Define Detrital, Chemical, and Organic (Three types of Sedimentary Rocks)
Detrital - Made from broken rocks
Chemical - When chemicals get deposited
Organic - Made from nature
Define weathering and erosion
Weathering - Nature breaks down rocks (rain, wind, snow, etc.)
Erosion - Redistribution of sediments
Name the three types of magma and describe the differences between the two of them.
Basaltic, Granitic, Andesitic
Basaltic - Rich in Iron and Magnesium and has a liquid-like magma
Granitic - Rich in Silica and is stiff like magma
List all 5 Stages of making a Sedimentary Rock
1. Transportation
2. Deposition
3. Sedimentation
4. Compaction
5. Cementation
Name an example of a sedimentary rock that changed into a metamorphic rock
Shale (Sedimentary) to Slate (Metamorphic)
