Based on what you know about changes in matter, explain why the diagram shows a physical change rather than a chemical change.
The composition of the matter stays the same.
300
When the boy releases the arrow, the amount of kinetic energy increases, and the amount of potential energy decreases. What happens to the total amount of energy?
It stays the same.
300
What are fossil fuels?
They are made from prehistorical plants and animals. Over time, the plants and animals were squished down and changed into 3 different fuel forms.
300
What are 2 important ways pollution travels?
The wind can blow it around, and the water can spread it.
300
What are the advantages of using renewable resources?
Advantages: They won't run out. They create almost no pollution at all.
