Answer:

The validation of seafloor spreading in the 1950s and 60s

Explanation:

The theory of seafloor spreading was supported by numerous evidence including thermal probes that showed that heat flow over the mid-ocean ridges measured up to four times those measured in general bottom sediments, which are taken as due to the presence of molten Earth material close to the ridge crest

The ridge crest also show signs unusually seismic wave velocities that are considered to be due to microfracturing and thermal expansion from upwelling magma

What is the density of an object with a mass of 140 g and a volume<br> of 6 ml
Strike441 [17]

Answer:

<h2>23.33 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume}  \\

From the question we have

density =  \frac{140}{6} =  \frac{70}{3}   \\  = 23.3333...

We have the final answer as

<h3>23.33 g/mL</h3>

Hope this helps you
