Transverse Waves
What type of wave moves the medium perpendicular to the direction of the wave?
Transverse Wave
What type of wave is an electromagnetic wave?
Transverse Wave
What are the three types of plate boundaries?
Convergent, Divergent and Transform
What is the first stage in the life cycle of a star?
Stellar Nebula
Name one example of a transverse wave found in nature.
Ocean Waves, Human Waves, Light Waves, Radio Waves, Microwaves
What type of career uses gamma rays?
Radiation therapy, Oncologist (cancer Dr. )
Who proposed the theory of continental drift?
Alfred Wegner
What are the 3 types of galaxies and draw what they look like
Elliptical, spiral and irregular
What causes a neap tide?
When the earth, sun and moon are aligned in a 90 degree formation. The moon is in its 1st quarter phase or 3rd quarter phase.
What is the highest point of a wave?
What is the lowest point of a wave?
Highest - Crest
Lowest - Trough
What is the type of electromagnetic wave we can see with our own eyes?
visible light
How do plate boundaries relate to earthquakes and volcanoes?
Earthquakes can come from transform boundaries and volcanos can be formed at a continent-ocean convergent boundary
What are the 4 types of stars found on a Hertzsprung Russel Diagram?
Main Sequence, White Dwarfs, Giants and Super Giants
What is creates a spring tide
When the Sun Earth and moon are in a straight line. During the full moon or new moon phases.
What is the wavelength of a transverse wave?
The distance from one crest to another or one trough to another.
Which wave on the electromagnetic spectrum has the longest wavelength and the lowest frequency?
Radio Waves
What was the main supercontinent called that existed millions of years ago?
Pangea
What is a black hole and how is it formed?
A black hole has so much gravity that no energy or matter could escape it not even light. It is formed after a Super Nova when the remnants mass is high.
Explain what is happening to the low and high tides during spring tide.
What is the amplitude of a wave.
The distance from the crest or trough to the resting point of a wave.
Describe the relationship between wavelength and frequency in the electromagnetic spectrum
Explain the concept of subduction in plate tectonics.
When a more dense plate sinks below a less dense plate at a convergent boundary.
What is cosmic background radiation?
Left-over radiation from the Big Bang?
Why do different parts of Earth experience different seasons?
