Rocks Flashcards
How are igneous rocks classified
According to shape and mineral content
Can sedimentary rocks contain living things
Yes
What does the shape of an igneous rock depend on
How the magma cools
T or f
The rocks cycle goes in the same order every time
False
T or f
The properties of a sedimentary rock are the same after metamorphism
False
What is a rock that’s formed from sediments
Sedimentary rocks
What’s a igneous rock
Rocks that are formed from cooled and hardened magma
What is an Extrusive rock?
Igneous rocks formed when lava cools on the earths surface
Intrusive?
Igneous rocks that are formed when magma cools beneath the earths surface
Magma?
Melted rocks beneath the earths surface
What is compaction
When pressure pushes the sediments together, squeezing air and water out of the spaces between the fragments
What is a foliated structure
Rocks with a foliated structure have viable layers and bands
What is metamorphism
The process of change in the structure and constitution of a rock
What kind of a rock is shale
Sed
What kind of rock is Quartz
Igneous
Diorite?
Igneous
Gabrro
Igneous
Marble
Metamorphic
Coal?
Sedimentary
Obsidian?
Igneous
Pumice
Igneous
Gneiss?
Metamorphic
Sandstone
Sedimentary
How is coal formed?
Formed from ancient plant remains compacted together, made of carbon
How is obsidian formed?
Formed when magma cools on the earths surface
How is pumice formed
It’s formed when magma cools and gas bubbles escape
Name and explain the rock cycle-essay
Cooling of magma into igneous rock👉🏼when igneous rocks are exposed to earths surface they break into fragmenta👉🏼weathering and erosion👉🏼compaction and cementation forms sedimentary rocks👉🏼when Sed rocks are exposed to extreme heat and pressure👉🏼metamorphic 👉🏼metamorphic rocks melt into magma and cycle repeats.
5 parts of rock cycle
Melting, solidification, weathering and erosion, deposition, compaction and cementation, metamorphism
Igneous is the Latin word for what
Fire
2 main classifications of igneous rocks
Malfic and felsic
Plastic
Flexible
Metamorphic rocks?
Are formed when the structure and constitution of existing rocks change due to heat pressure and chemical reactions
Sedimentary rocks
Rocks formed from sediments that have been compacted and cemented together
Clastic rocks
Sedimentary rocks made of rock particles and fragments deposited by water wind or ice
Conglomerate rocks
Is a classic rock composed of round pebble sized rock particles they form where sediments are depositors
Definition of weathering
When forces of weather break down rocks into sediments
What can rocks teach us about Gods creation
The rock cycle is so detailed and planned out that it can not just be a coincidence, the cycle shows that there must be a overall creator of the earth-God
How are igneous rocks formed?
When magma hardens
