*You are in your seat and on-task!!
What makes hot air balloons rise??
Which box is more dense?
Density is the mass per unit volume
In other words…
When something is cold, its particles are closer together. This means that it will be more dense.
If something is warm, its particles are farther apart. This means it will be less dense.
PREDICT: Which will be more dense, the karo syrup on the hot plate, or the karo syrup from the refrigerator? Why?
What happened to the cold karo syrup when it was added to the warm karo syrup?
Why do you think that happened?
The core of the earth does not heat the mantle directly. As the outer core warmsup certain parts of mantle, the magma becomes lessdense.
drawn to show the rising and falling magma.
