Answer:

6.9 hours

Explanation:

In order to solve this problem we'll<u> convert 837 km to miles</u> (another option would be to convert 75 mi/hr to km/hr). To make said conversion we'll use the given <em>conversion factor</em>:

  • 837 km * \frac{1mi}{1.61km} = 519.88 mi

Finally we <u>calculate the time required to travel said distance</u> at a constant speed of 75 mi/hr:

  • 519.88 mi ÷ 75 mi/hr = 6.9 hr

In what way do the oceans and the forests perform a similar function in the carbon cycle, under normal conditions?.
ikadub [295]

Both take carbon dioxide out of the atmosphere.

The ocean absorbs much of the carbon dioxide released when fossil fuels are burned. This extra carbon dioxide lowers the ocean's pH through a process called ocean acidification. Both are important elements for all life on earth. Relationship between the water cycle and the carbon cycle. The sun's energy drives both the carbon cycle and the water cycle.

Recall that sunlight water and carbon dioxide combine in green plants via photosynthesis to produce carbohydrates. The ocean also regulates the Earth's climate. They determine the weather by telling temperatures and determining rainfall, droughts, and floods. It is also the world's largest carbon sink, with an estimated 83% of the global carbon cycle circulating in seawater.
