earth science Flashcards
what is a rock made of
mixtures of minerals
how does igneous rock from
magma cooling
what is marbles parent
limestone
what is a metamorphoic rock
when sedimentary rock compact together/heat and pressure
waht are sedimentary rocks
sediments that are pushed together
can igneous rock form above the surface
yes
how do igneous rocks turn into sedimentary
erosion and depostion
how are fine and course grained textures formed
forms from magma or lava cooling quickly/ course is from it cooling slowly
what are the three compositons of igneous rocks
granitic,basaltic,andesitic
what is deposition
depostion is the settling of sediments in layers after it was moved during erosion
what is wheatering
the process of rocks when they break into smaller pievces
what is erosion
rocks broken down by wind or water and carried somewhere
what is cementation
when water soaks through soil or rock
what is a clastic sedimentary rock
made from broken pieces of other rocks and it compacted and cemented together
what are chemichal rocks
chemical rocks form from water precipitation or evaporation
