Nonrenewable Resources
What are non-renewable resources? Why must we conserve them?
We have a finite amount of them and we will run out if we dont live sustainably.
What type of energy do tidal waves have?
Kinetic.
Wheel that spins around to generate electricity?
Turbine.
What happens, as the frequency of a wave increases?
The wavelength increases, and energy decreases.
Originally, Amazon only sold what kind of product?

Energy source that may disrupt fish migration.
Hydroelectric.
What happens to light waves when it travels from a dense medium to a less dense medium?
The line bends away from the normal line because it has less particles to collide with.
Which athlete has won the most Olympic medals? With how many?

What are advantages and disadvantages of geothermal energy?
Advantage- constant source of energy & plant produces low emissions
Disadvantage- limited to areas with volcanic or tectonic activity. Drilling causes earthquakes and disrupt ecosystems.
What are some disadvantages using alternative resources?
They are only available at certain times or in certain places and most sources are expensive to get started.
What is gravitational potential energy?
The energy an object has because of its height above the ground.
Carbon has two isotopes: C-12 and C-14. What is the same, and different about those two isotopes?
They have the same number of protons and electrons, but different number of neutrons, leading to a different mass number.
What is the name of the world's largest volcano and where is it located?
