300
What is lithifaction
the process of sediment becoming compacted and cemented into stone
300

Marble
300
What drives the rock cycle
Plate techtonics
400
what is the process which metamorphic rock is formed
What is metamorphism
400
what factor affects how large crystals will grow.
the speed of which the molten rock cools
400
What kind of sedimentary rock forms when minerals that are dissolved in a solution crystalize
chemical rocks
400
Regional metamorphism happens at _____________ plate boundaries. Heat and ____________________ happens here to make a very large amount of metamorphism.
convergent plate boundaries. Pressure
400
Which would have larger crystals, intrusive or extrusive rocks. explain why
intrusive because magma cools slower allowing larger crystals to form
500
Igneous rocks may be similar in mineral make-up and yet have different ____________. Examples are porphyritic, course grained, and glassy
What is textures
500
For each of the following rocks tell me if it is intrusive or extrusive.
Granite
Obsidian
Basalt
Pumice
What is Intrusive, extrusive, intrusive, extrusive
500
What is erosion
The process by which natural forces move weather rock from place to place
500
Contact Metamorphism happens at ______________ plate boundaries. __________________ changes and heat create metamorphic rocks near the magma around it.
divergent. chemical
500
Why is metamorphic rock happen in areas with intrusive igneous rocks and where tectonic plates collide
Intrusive igneous rocks occur in areas where there was once a lot of heat and convergent plate boundaries have a lot of pressure and heat
