What is lava?
Examples of Sediments
Broken down pieces of rock,

Soil
True of False- Metamorphic rocks can change in size and shape.
True- due to intense heat and pressure
Undergoing weathering and erosion, will eventually form which type of rock?
Sedimentary Rock
Define sandstone.
Compacted sediment that has formed into rock.
When did you observe erosion in class?
When the sugar melted/dissolved when adding water drops during the sugar cube lab.
Igneous rocks are categorized as _________ or _________, depending on where the molten rock cooled.
What are extrusive and intrusive.
A sedimentary rock can change during the rock cycle. True or False?

False! It is a never ending cycle.
Name a way plants can weather rocks.
Grow into cracks and making them bigger.
Moss can grow on rocks and produce a weak acid.
