What is a dam?
A dam is a big wall built across a river, that hold freshwater.
Give an example of physical weathering.
Animal actions, plant roots, running water (erosion), heat, or wind abrasion.
When do we use a line graph?

What is the variable that you change in an experiment called?
The independent variable
Which phase change deals with a gas turning into a liquid (ie. water vapor to water)?
Condensation or condensing
How does a turbine make electricity?
Water spins a turbine, and the spinning creates electricity.
What type of weathering deals with chemical reaction bonds breaking and creating new substances?
Chemical Weathering
What is the format for the title of a graph?
The Effect of the IV on the DV
What is the variable that you measure in an experiment?
The dependent variable
What is density?
How tightly packed matter is OR how much mass something has.
How do ocean waves create electricity?
Floats in the water bob up and down, and that movement sends a message to a generator, making electricity.
How does frost wedging split a rock?
Water gets into cracks and freezes causing it to expand over time.

How does hydropower help farmers during a hot summer with no rain?
Dams trap extra water so farmers can use it during dry weather.
How does acid rain affect buildings?
Acid rain dissolves and weakens minerals inside, causing new minerals to form
Carter wants to graph his data on an experiment he did. He figured out if a parent frogs has warts, then, the baby frog will have warts. What is the title of Carter's graph?
