rocks weathering erosion and deposition
what are rocks made of
rocks are made up of minerals
what is the rock cycle
processes that explain the relationship between the three rock types: igneous, sedimentary, and metamorphic
how does sedimentary rock form
when minerals that form solutions get pressed and cemented together
how does igneous rock form
when magma or lava cools to become solid
how does metamorphic rock form
it forms when pressure,temperature or chemical processes change existing rock
what does weathering do
weathering breaks down rock into fragments called sediment
What process causes igneous rock to transform into metamorphic rock?
high heat and high pressure,
what rocks can form from sedimentary
metamorphic and igneous
what is an example of igneous
diorite, gabbro, granite and pegmatite
what is an example for metamorphic rock
phyllite, schist, gneiss, quartzite and marble.
what is erosion
when water,wind,ice and gravity break downs rocks
What rock groups can form from metamorphic rock?
sedimentary and igneous
what is an example of sedimentary rock
sandstone,limestone and shale
what rocks can form from igneous rock
sedimentary and metamorphic
what rocks can form from metamorphic rock
igneous and sedimentary
what is deposition
when sediment rests in water or low lying areas and gets carried away
do sedimentary rocks have crystals
yes
can igneous rocks have crystals
yes
do metamorphic rocks have fossils
no
