What is an igneous rock?
forms when lava or magma cools and solidifies
formed deep underground due to heat and pressure
forms when particles of other rocks are deposited in layers and compacted and cemented
What is a metamorphic rock?
forms when lava or magma cools and solidifies
formed deep underground due to heat and pressure
forms when particles of other rocks are deposited in layers and compacted and cemented
What is a sedimentary rock?
forms when lava or magma cools and solidifies
formed deep underground due to heat and pressure
forms when particles of other rocks are deposited in layers and compacted and cemented
Define the rock cycle.
forms when particles of other rocks are deposited in layers and compacted and cemented
Earth’s rocks change from one type into another over time due to various Earth processes
a repeated sequence of events
when your favorite rock band plays the same song over and over again
Define cycle.

Which choice best describes the formation of a sedimentary rock in the process known as the rock cycle?
forms when an igneous or metamorphic rock is subjected to natural process such as erosion or weathering making
sediments are deposited in the same area
sediments continue to be deposited causing the sediments to be compacted and cemented together
Which choice best describes the formation of a metamorphic rock in the process known as the rock cycle?
existing rocks are put under great heat and pressure
sediments are deposited in the same area
sediments continue to be deposited causing the sediments to be compacted and cemented together
formed when lava or magma cools and forms crystals
Which choice best describes the formation of an igneous rock in the process known as the rock cycle?
existing rocks are put under more heat and pressure; resulting in movement of rock deeper under Earth's surface
rock is pushed towards the mantle where it melts
formed when lava or magma cools and forms crystals
Which choice describes what a sedimentary rock looks like?
distinct layers or bands; fossils may also be visible
wavy band and crystals appear mashed together
layers are not present; crystals are visible; colors appear speckled in no specific pattern throughout the rock
Which choice describes what a metamorphic rock looks like?
distinct layers or bands; fossils may also be visible
wavy band and crystals appear mashed together
layers are not present; crystals are visible; colors appear speckled in no specific pattern throughout the rock

What were the variables tested in the Crystallization of Igneous Rock lab?
cooling method
crystal formation
deposition of sediments
heat and pressure placed on rock
What pattern or trend was seen between the two variables?
As the temperature of the method used to form crystals increased the time it took to form crystals increased.
sediments to form a sedimentary rock collected more rapidly
the heat and pressure applied to the metamorphic rock increased
What predictions can be made about cooling conditions of igneous rocks based on the size of the crystals observed on the microscope slides?
rock cooled slowly
rock cooled extremely quick
rock was not cooled
sediments were collected at a quick rate
