A student reads the list above. She wants to add wind as a natural resource. To what side of the list should wind be added and why?

• Renewable Resources; it is always moving

• Renewable Resources; it cannot be used up

• Nonrenewable Resources; it cannot form naturally

• Nonrenewable Resources; it is difficult to form naturally

One of the most important reasons that people use Earth's resources is for energy. Which resource do you predict would take the longest amount of time to form?

A student reads through the chart to identify natural resources found in Florida. Which Florida natural resource is renewable?

• oil

• coal

• wood

• limestone

What process is taking place in the diagram?

• Temperature changes are causing the rock to weather.

• Erosion is causing temperature changes in the rock.

• Weathering is causing sedimentary rock to form.
