what is most of the earths compromised
igneous rocks
what are metamorphic rocks are mainly comprised of?
other rocks that are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors
what are sedimentary rocks mainly comprised of?
pre existing rocks / orginsams
what is a basic def for the rock cycle?
rock cycle is a web of processes that outlines how each of the three major rock types—igneous, metamorphic, and sedimentary—form and break down based on the different applications of heat and pressure over time
magma
hot fluid or semifluid material below or within the earth's crust from which lava and other igneous rock is formed on cooling.
what are igneous rocks made of?
hot molten rock crystallizes and solidifies
what are metamorphic rocks mainly used for?
artwork and basic archetuecture.
what are sedimentary rocks mainly used for?
energy sources
how do tectonic plates affect the rock cycle
The heat from the mantle that fuels plate tectonics turns bare and sedimentary rocks into metamorphic rocks. Metamorphic rocks can be converted into sedimentary rocks and dissolved into igneous rocks
weathering?
the process of wearing or being worn by long exposure to the atmosphere.
how do other rocks change into igneous rocks?
how do other rocks change into metamorphic rocks?
rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors
how do other rocks change into sedimentary rocks?
erosion and weathering
how long can the transformations in the cycle take?
millions of years.
compaction
the exertion of force on something so that it becomes more dense.
one of the most well known igneous rocks?
Obsidian
what are the two most well known metamorphic rocks?
quartzite and marble
what are some more famous sedimentary rocks?
Sandstone, Limestone
who had the idea for the rock cylce?
cementation?
the binding together of particles or other things by cements
how are igneous rocks formed?
Igneous rocks are formed from melted rock deep inside the Earth
whats one of the most famous structures made of metamorphic rocks
Tower of pisa
what are sedimentary rocks used for
building stones
what is the rock cycle ( in what order do the rocks change ) ?
crystallization, metamorphism, and erosion and sedimentation (any of the rocks can go through these processes no matter the time).
sediment
solid material that is moved and deposited in a new location.
