A major volcanic eruption put large amounts of dust into the upper atmosphere. For three years following the eruption, Earth’s weather was cooler than normal. Which of the following is NOT a testable hypothesis regarding the relationship between the eruption and the weather?
Making products from recycled materials, such as aluminum cans, glass, and plastic usually saves energy and other resources. For example, it takes about 75% less energy to make steel from scrap than from ore. All forms of recycling involve some energy to produce the recycled materials, a process that also results in the production of some pollution.
The chart at the left shows the energy savings from recycling.
When Anil is at the grocery store, he can choose to buy juice in a glass bottle, an aluminum can, a plastic jug, a juice box (paper), or foil-covered juice container.
If Anil’s community requires that he recycles, which container would provide the MOST overall energy savings?
When electricity passes through a wire, there is a resistance to the flow of current. This resistance causes wires or any other conductors of electricity to heat up. The chart below summarizes the relationship between wire diameter and length and the flow of electricity.
A heavy-duty extension cord is made of a thicker wire than a regular extension cord and is recommended for appliances that draw considerable current, such as air conditioners and power tools.
Which situation would most likely occur if a regular extension cord were substituted for a heavy-duty cord?
As plants grow, they absorb nutrients from the soil. Plant leaves can be carefully observed to determine the relative healthiness of the plant and whether it is suffering from a nutrient deficiency. The chart below shows the most common nutrient deficiencies and their effects on plant leaves.
A plant has leaves that are yellowing at the tips and margins with dead spots on the leaves.
