Please help!! I WILL GIVE BRAINLIEST !! Can you figure out the modern spreading rate of the Mid- Atlantic ridge? Use that line t
Naddik [55]

Answer:

R = 16mm/y  

Explanation:

Modern Spreading Rate (R) = distance the seafloor moved in km (d) / age in million years (t)

R = d/t

To calculate it in millimeters per year we need to convert it:

<em>1 km = 1000 m </em>

<em>1 m = 100 cm </em>

<em>1cm = 10mm</em>

<em>1 km = 1,000,000 mm   </em>

The problem states that in 150 million years, there is a distance of 2400 km.

if 1 km ------- 1,000,000 mm

2400 km-------X = 2400,000,000 mm

If 1 million years -------1,000,000 years

150 my----X = 150,000,000 years

R = d/t

R = 2400,000,000 mm/150,000,000 y.

R = 16mm/y

klio [65]

Answer:

D

Explanation:

Crude oils, shale,  and natural gas are some of the fossil fuels formed in this way. They are specially formed when vast amounts of algae die and sink to the bottom of the oceans over time and accumulate with sediments. They become buried under vast layers of sediments that apply high pressure. Over time, the high pressure and temperature turn the organic molecules into fossil fuels.
