Sedimentary
A sedimentary rock made of smaller rock fragments such as the rock conglomerate has what type of texture?
Clastic
Metamorphic rocks are classified by which 2 texures?
Foliated and Non-foliated
Granite is an Igneous rock that formed below the surface from slow cooling and crystallization of magma. What texture is Granite?
Course- Grain
What processes are needed to change sediment into metamorphic rock?
Compaction and cementation, heat and pressure
What two ways do geologists classify rocks?
Color and Texture
A sedimentary rock that forms from the remains of animals and plants such as limestone has what type of texture?
Organic
Gneiss is a metamorphic rock that contains bands of light and dark minerals. What is the texture of this rock?
Foliated
Rhyolite forms on the surface from rapid cooling and crystallization of lava. It contains crystals that cannot be seen by the naked eye. What texture is Rhyolite?
Fine-Grain
What processes are needed to change magma into sediment?
Cooling and crystallizing (above surface), weathering and erosion
What are all rocks made of?
Minerals
Gypsum is a sedimentary rock that formed from minerals that were dissolved in the rock when exposed to solution. Gypsum is what texture?
Chemical
Marble is a metamorphic rock that contains crystals and many light colored minerals. What is the texture of this rock?
Nonfoliated
Obsidian is a glassy texture Igneous rock. It forms from extreme rapid cooling and crystallization of lava on Earth's surface. Is Obsidian intrusive or extrusive?
Extrusive
What processes are needed to change sedimentary rock into magma?
Heat and pressure, melting
What is the process in which any type of rock is broken down into sediment?
Weathering
Breccia is a sedimentary rock that contains angular rock fragments of various sizes. What texture is it?
Clastic
Explain one use for metamorphic rock.
Roofing, countertops, flooring, building material etc.
Gabbro is an Igneous rock with grains and crystals that are visible to the naked eye. Is it intrusive or extrusive?
Intrusive
Give an example of a rock cycle that visits all 5 stages.
