100
These are the basic characteristics of a longitudinal wave.
What are amplitude, rarefaction, and compression?
100
If in a container, gases will act in this way.
What is take the shape of their container?
100
The sun loses energy in this way.
What is by emitting light?
100
This number of planets move around the sun in nearly circular orbits.
What is eight?
100
Surround and control the size of the opening in stomata.
What are guard cells?
200
When light waves enter here, they can be seen.
What is the eye?
200
If gases are unconstrained they will act in this way.
What is spread out?
200
This much of the Sun's energy gets transferred to the Earth.
What is a tiny fraction?
200
Some planets have these orbiting around them.
What is a variety of moons and even flat rings of rock and ice particles?
200
The loss of water through the stomata.
What is transpiration?
300
Human eyes respond to this much of wavelengths of electromagnetic waves (visible light).
What is a narrow range?
300
Gas particles have this density.
What is very low?
300
The sun's energy arrives to Earth as light, with a range of this.
What are wavelengths?
300
The earth is orbited by these.
What is one moon, many artificial satellites, and debris?
300
This regulates transpiration.
What is the opening and closing of the stomata?
400
Humans perceive differences of wavelength as this.
What are differences in color?
400
The disorderly motion of molecules is called.
What is heat energy?
400
The portion of the electromagnetic spectrum that is visible to human eyes.
What is visible spectrum?
400
Consists of the Sun, planets, moons, asteroids, meteors, comets, dust, gases and primarily empty space.
What is our solar system?
400
Plants use this to make sugars and carbon dioxide and water.
What is the energy from light?
500
Light travels as these types of waves.
What are transverse waves?
500
When a temperature is increased, this will happen to atoms and molecules.
What is have a greater average energy of motion, and therefore expand?
500
Visible light or simple light is also referred to as this.
What is electromagnetic radiation?
500
This is the major source of heat and light for our solar system.
What is the sun?
500
These are the producers of food that is used directly or indirectly by consumers.
What are green plants?
