Which is an example of a chemical change that occurs as part of the rock cycle?
lava cools and condenses on the Earth's surface
igneous rocks are cracked and broken into smaller pieces by weathering
sedimentary rocks are turned into metamorphic rocks by heat and pressure
sedimentary rocks are worn away by water erosion
Which of these would be caused by a chemical change?
Sedimantary rock layering over time.
Metamorphic rock eroding to form sedimentary rock.
Metamorphic rock forming from igneous.
The formation of lava.
What does this diagram represent?
RNA
a gene
DNA
an allele
The distance from point A to point B is known as the
wavelength
amplitude
volume
wave height
Which two forms of energy travel in waves?
heat and electricity
electricity and mechanical motion.
mechanical motion and light
light and sound
Which statement about metamorphic rock is true?
It is created from magma.
It is created through lithification.
It can be created from sedimentary rock.
It forms through crystallization.
What causes sedimentary rock to change into metamorphic rock?
heat and pressure
cooling
weathering and erosion
melting
What statement BEST describes sound?
It’s a form of work.
It’s a type of acceleration.
It’s a form of energy.
It’s a type of force.
Allen and his lab partner each held a tuning fork, frequency 440 Hz, in their hands. Allen tapped his tuning fork with a mallet and they listened to the sound it made. "Wait a minute!" exclaimed Allen's partner. "My tuning fork is vibrating too!" Sure enough, both tuning forks were vibrating although only Allen hit his with the mallet. How can you explain this?
Sound energy travelled as particles from one tuning fork to the other.
Sound particles caused the second tuning fork to vibrate.
Sound energy travelled as waves from one tuning fork to the other.
Sound waves are transferred to the tuning fork.
