Weathering
the process where rocks are broken down into smaller pieces
What is weathering?
broken down pieces of rocks
What are sediments?
this super hot liquid rock has two names and forms igneous rocks
What is molten material?
these types of rocks can turn into metamorphic rocks
What are rocks (sedimentary, igneous, metamorphic)?
lava/magma becomes igneous rock
What is cooling?
the process where rocks are broken down by things such as wind, water, etc.
What is physical weathering?
sediments are laid down in layers during this step of forming sedimentary rocks
What is deposition?
the process (action) that creates igneous rock
What is crystallization?
these two forces form metamorphic rocks
What is heat and pressure?
igneous rock becomes sedimentary
What are weathering, erosion, deposition, compaction, and cementation?
the process where rocks are broken down by chemical reactions, typically making something new
What is chemical weathering?
layers of rocks getting squeezed together
What is compaction?
this type of igneous rock forms inside the earth
What is intrusive igneous rock?
instead of layers or stripes, this pattern is found on metamorphic rocks
What are ribbon like layers?
sedimentary rock becomes metamorphic
What are heat and pressure?
this is when water gets into the crack of a rock, freezes, and when it thaws pieces of the rock break off
What is ice wedging?
layers of rocks bonding (gluing) together
What is cementation?
this type of igneous rock forms on Earth’s surface
What is extrusive igneous rock?
the amount of years it takes to form metamorphic rock
What are thousands (or millions) of years?
metamorphic becomes lava/magma
What is melting?
occurs when oxygen reacts with iron to form iron oxide
What is rust?
these are only found in sedimentary rocks
What are fossils?
this super hot liquid rock is above earth’s surface
What is lava?
this is what you will get if you put a metamorphic rock under heat and pressure
What is a metamorphic rock?
rocks become sediments
What is weathering?
