Allison pulls her cold soda out of the fridge. the soda after being at room temp it begins to form water droplets that disappear once the drink is no longer cold. Alison then puts the drink back in the fridge, later pulling it back out and getting the same reaction as the first time. What biogeochemical cycle is beillustratedated?

• carbon cycle

• water cycle

• nitrogen cycle

A student is told to list how nitrogen is presented in the atmosphere in its natural state before nitrogen fixation. What does the student write?

Carbon is present in fossil fuels that are buried for a long time the fossils are then dug up. They are then burned and put into the atmosphere. Carbon is then diffused into the ocean from the atmosphere. Through the whole carbon cycle does carbon change or just change location?

• Change

• Just change locations
