A student mixes vinegar and baking soda in a closed container. The mass of the container and its contents before the reaction is 250 g. After the reaction, the mass remains 250 g. Why does the mass stay the same?
Mass is conserved because atoms are rearranged but not created or destroyed.
What is the basic principle behind convection currents?
Convection currents are driven by differences in temperature and density. Warm materials rise, while cooler materials sink
What are the 4 plate boundaries?
convergent collision, convergent subduction, divergent, transform
When looking at a weather forecast, how can you tell there is a warm/cold front coming? Describe it
Bubbles = warm front
Spikes = cold front
Name a green vegetable that is bumpy and sour
pickle!
How long does the entire lunar cycle take?
28 days or 1 full month
Analyze the chemical formula Al₂(SO₄)₃. How many atoms of aluminum (Al), sulfur (S), and oxygen (O) are present?
Aluminum - 2
Sulfur - 3
Oxygen - 12
Classify the following as an element, compound, or mixture:
What causes and strengthens a hurricane?
WARM WATER
The sky is....
blue
What phases occur during a Neap Tide?
Can you give a simple example of a convection current in action?
When you boil water in a pot, the heat from the stove warms the water at the bottom. This warm water rises, while the cooler water at the top sinks to take its place. This circular movement of water is a convection current.
If two plates are sliding past each other horizontally, what type of boundary is it?
Transform
which of the following is a chemical change?
a. melting ice
b. boiling water
c. burning wood
d. dissolving sugar
Burning wood
List Newton's 3 Laws
1: Inertia
2: Acceleration
3: Action and Reaction
What are the 4 main phases?
New Moon, Full Moon, 1st Quarter, and Last (3rd) Quarter
How do convection currents transfer heat?
Convection currents transfer heat by the movement of the fluid itself. The warm fluid carries the heat energy with it as it rises, and then releases the heat as it cools and sinks.
A car travels 150 km in 3 hours. What is its average speed?
Average Speed: __________ km/hr
50 km/hr
Describe a cold front
dry cold wind, cloudy, strong winds
Matter is neither created nor destroyed
Identify whether each element is a metal, nonmetal, or metalloid:
A box is pushed with 25 N to the right and 10 N to the left. What is the net force and direction?
Net Force: __________ N
Direction: __________
15 N to the right!
Describe each plate boundary
convergent collision, convergent subduction, divergent, transform
A car suddenly stops, and the passengers move forward. Which of Newton's laws best explains this phenomenon?
A) First Law – Law of Inertia
B) Second Law – Force = Mass x Acceleration
C) Third Law – Action and Reaction
D) None of the above
C) Third Law – Action and Reaction
