Rock Cycle
Intrusive Igneous
Extrusive Igneous
Sedimentary
Metamorphic
100
An cycle of processes undergone by rocks in the earth's crust, involving uplift, erosion, transportation, deposition as sedimentary rock, metamorphism,melting, and other things.
What is the rock cycle?
100
Because the process of the formation of intrusive igneous rock occurs slowly, these rocks tend to have a ---- texture.
What is grainy
100
Is extrusive igneous formed through consolidation or crystallization?
Consolidation
100
Sedimentary rock comes after what step in the rock cycle?
Lithification
100
True or false? Metamorphic rocks have been changed over time by extreme pressure and heat.
True
200
The steps after the stage of 'magma'
What is crystallization and consolodation?
200
-- percent of the Earth's crust is made of igneous rock.
95%
200
Does magma cool quicker in water or in air?
Water
200
Are sedimentary rocks formed above ground or under water?
What is a trick question. It's both.
200
Metamorphic rocks can be formed by pressure (deep under/right above) the Earth's surface, from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
What is deep under
300
After ----- hits the surface, it is called lava
What is magma
300
Intrusive igneous is formed through -----
What is crystallization
300
Extrusive igneous rocks are characterized by ---- ------- textures because their rapid cooling at or near the surface did not provide enough time for large crystals to grow
What is fine grained
300
The study of the sequence of sedimentary rock strata is the main source for scientific knowledge about the -----'s history
What is earth
300
Metamorphic rock forms when a rock is changed by ---- or --------, or by a -------- reactions.
What is heat, pressure, chemical
400
Through ----,----,----,---- and ----, the rock cycle constantly changes rocks from one type into another type.
What is melting, weathering, erosion, heat, and pressure.
400
There are over --- different kinds of igneous rocks that have been identified.
700
400
True or False?Extrusive refers to the mode of igneous volcanic rock formation in which hot magma from inside the Earth flows out (extrudes) onto the surface as lava or explodes violently into the atmosphere to fall back as pyroclastics or tuff.
True
400
True or False? Sedimentary melts back into magma.
False. (its metamorphic)
400
During ------- ------------, broken down pieces of rock near the Earth's surface is altered by magma.
What is contact metamorphism
500
Recite the entire rock cycle, starting with the path of consolidation
What is magma, consolidation, extrusive igneous, weathering, transportation, deposition, lithification, sedimentary rock, metamorphism, metamorphic rock, melting, magma (again), then crystallization, uplift and exposure, weathering, transportation, deposition, litification, sedimentary rock, metamorphism, metamorphic rock, melting, then magma once again.
500
Pumice belongs in this group of rock.
What is igneous
500
Rocks with this fine-grained texture are called ------- rocks
What is aphanitic
500
Sedimentary rocks cover the majority of the Earth's rocky surface but only make up a small percentage of the Earth’s crust compared to ----------- and ------- types of rocks.
What is metamorphic and igneous
500
------ is a nice metamorphic rock! (Hint: It's a pun)
What is gneiss
