Waves
Mechanical waves must have this to travel.
What is a Medium? (State of matter or a material to move through)
What are the poles?
The theory that states the universe began as a hot, dense singularity.
What is the Big Bang Theory?
What is the crust?
The name of the giant pieces of Earth’s crust that move slowly.
What are tectonic plates?
What a quiet wave would look like.
What is a wave with low amplitude?
The materials needed for an electromagnet.
What is a battery, copper wire, and iron nail?
During planet formation, smaller objects called these collide and combine to form larger objects.
What are planetesimals?
This layer, located beneath the Earth's crust, is made of solid and semi-solid rock and is responsible for tectonic movement.
What is the mantle?
Type of plate boundary happens when two plates move apart
What is a divergent boundary?
What is from the rest point (middle of the wave) to the crest or trough?
This is two examples of magnets that would show repulsion.
What is north and north, and south and south.
This is the term for the flat, spinning disk of gas, dust, and ice that surrounds a forming star and eventually gives birth to planets.
What is a protoplanetary disc?
The materials P-waves can move through, and materials S-waves can move through.
What is solid and liquid, and what is solid only.
Landform that is created when magma rises at a divergent ocean boundary
What is the mid-ocean (mid-Atlantic) ridge?
Increasing the frequency of a wave would do this to the wavelength.
What is shorten the wavelength?
The part of the electromagnet that is actually magnetic, and how can you make it stronger?
What is the nail, and add more loops or get a bigger battery?
The final process that brings planets together.
What is accretion?
Layers of the Earth that S-waves can travel through.
What is the crust and mantle?
Reason behind one plate to sink beneath another at a convergent boundary (subduction)
What is the more dense (oceanic) plate will sink?
This amplitude and frequency would create the highest amount of energy in a wave.
What is high amplitude and high frequency?
When an electric current flows through a wire, it creates this type of field around the wire, which is essential for the electromagnet’s function.
What is a magnetic field?
If X revolves around Y, and Y revolves around Z, the sun, moon, and Earth can be labelled as such.
What is X is the moon, Y is Earth, and Z is the sun.
P waves can be considered stronger than S waves for these 3 reasons.
P waves arrive first, they are faster, and can move through any material.
Reason for fossils of the same species found on continents far apart today
What is continental drift/ continents used to be together?
