How are kinetic and potential energy different?

Kinetic = motion

Potential = stored energy

In your own words, explain how mass and weight are different.

Mass is how much matter. Weight is how hard gravity is pulling on something.

Explain how the muscular and skeletal systems related. Give at least 2 reasons.

They work together to:

1) Move the body

2) Protect the organs

What is the word for the measurement of a wave from the resting line to the crest?

Amplitude

300

Define density in your own words.

How much mass is held in a certain volume of a substance OR how many particles are in a certain amount of a substance.

Lake Ontario, one of the Great Lakes, usually receives heavy snowfall during the winter. Snow often falls after a cold air mass passes through the area. This air mass tends to be colder than the lake water.
Which of the following best explains why snow falls over the lake after the air mass passes over it?

A. The air mass pushes clouds over the lake, and snow falls from the clouds. 

B. Snow falls when sinking air from the air mass is warmed by the lake water. 

C. The air mass cools the surface of the lake, causing condensation to occur and snow to fall. 

D.Snow falls from clouds that form when rising water vapor from the lake is cooled by the air mass and condenses.

D. Snow falls from clouds that form when rising water vapor from the lake is cooled by the air mass and condenses.

EXPLAIN THIS: What is the role of the Vacuole? What does it do for plant cells?

Daily Double

The vacuole stores water, food, and waste. It adds structure to the plant cell AND provides extra water.

What process causes the tectonic plates to move? Explain how this works.

Convection currents. Explanations will vary.
