Question

question 7 (multiple - choice worth 5 points)
tg.05what would a scientist most likely do to predict the damages due to a volcanic eruption?
make a real volcano erupt by heating magma
construct a model of a volcanic eruption
increase earths temperature by artificial methods
take photographs of earths interior during eruptions
question 8 (multiple - choice worth 5 points)
tg.02the chart below shows some sources, processes, and products in the carbon cycle. not all information in the chart is correct.

source of carbon	process	product
animals	excretion	carbon in atmosphere
seawater	diffusion	carbon in soil
plants	consumption	carbon in land animals

which of these statements best describes a method to correct the flaw in the chart?
interchange carbon in soil and carbon in land animals.
interchange carbon in soil and carbon in atmosphere.
interchange carbon in green plants and carbon in atmosphere.
interchange carbon in green plants and carbon in land animals.

Explanation:

For Question 7, making a real - volcano erupt is dangerous and unethical, increasing Earth's temperature artificially is not related to predicting volcanic eruption damage, and taking photographs of Earth's interior during eruptions is currently impossible. Constructing a model of a volcanic eruption is a common scientific method for prediction. For Question 8, during the carbon - cycle, diffusion from seawater leads to carbon in the atmosphere, not carbon in soil. Interchanging carbon in soil and carbon in the atmosphere corrects the error in the chart.

Answer:

Question 7: B. construct a model of a volcanic eruption
Question 8: B. Interchange carbon in soil and carbon in atmosphere
