The sun gives off what types of energy (2)
EM/Light and Thermal/Heat
the substance that a wave passes through
medium
What electromagnetic wave has the lowest energy
Radio
Heat flows from
Hot to Cold (less hot)
Higher energy to lower energy
Competition
Burning wood is what type of energy transformation
Chemical to Heat/Thermal
Sound waves travel fastest in this medium
solid
higher
When does heat energy stop flowing?
When they are the same temperature
This gets its energy from the sun and makes its on food
Producer

Infrared
Sasha drops some of her ice cream sundae on a hot sidewalk. Heat from the sidewalk is transferred to ___________________ causing______________.
transferred to the icecream causing it to increase in temp or melt
An important need for a bird is a safe place to build a nest. If a bird did not have a place to build a nest, what would most likely occur?
The number of offspring will decrease
What type of energy is being transformed when a fan is turned on: Electrical --->
Kinetic
When light travels through a material, but it is bent causing an optical illusion
Radio waves are different that x-rays because...
Radio waves have a longer wavelength
Radio waves have a lower frequency
Radio waves have less energy
What is needed to cause a liquid to change to a gas and solid to change to a liquid
Need to add heat energy
Why are decomposers an essential part of a healthy ecosystem?
They recycle nutrients back to the environment
What happens to kinetic and potential energy as Bob rides his bike up the hill
Potential increases, kinetic dereases
Bob is wearing a blue tshirt, why does it appear blue?
Blue is being reflected, all other colors are absorbed.
Radio waves and visible light are used in telescopes here on Earth. Why do astronomers use telescopes in outer space for other types of EM waves?
Radio waves and visible light can pass through Earth’s atmosphere, but the atmosphere reflects or absorbs most other types of electromagnetic radiation.
