What are the 3 ways heat can move?
|
|
|
Greenhouse effect
|
What is the process called when gases from the earths atmosphere hold in heat from the sun?
|
|
|
Compressional wave and transverse wave
|
What are the two main types of waves?
|
|
|
Energy
|
What do all waves carry?
|
|
|
Shorter
|
Which has more energy waves with a shorter or longer wavelength.
|
|
|
It always moved from warmer to cooler.
|
What is always true about the movement of heat?
|
|
|
Up & Down
|
When a transverse wave moves through matter which direction does the matter move?
|
|
|
It moves back and forth
|
What happens to matter when a compressional wave moves through matter?
|
|
|
transverse waves that can travel through empty space
|
What type of waves are light waves?
|
|
|
Gamma Rays
|
In the electromagnetic spectrum, waves have the greatest frequency and the shortest wavelength?
|
|
|
Light refracts, or changes direction, when it moves from water to air.
|
Why does a straw in a glass of water look bent when you look at it from the side?
|
|
|
the wavelengths that the object absorbs and reflects
|
What determines an object’s color?
|
|
|
The atmosphere could become too warm. Increased temperature can have harmful effects on ecosystems.
|
What effect could an increase in atmospheric carbon dioxide could have on living things on Earth?
|
|
|
Particles in the cooler object start to move faster. Heat flows from the warmer to the cooler object. Warm cools & cool warms.
|
What happens to the particles in each object when a conductor of heat touches a cooler object?
|
