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
Answer
1. 1cm=10mm, 1kg=1000g and 12in=1 ft
2. 50mm=5cm
48 in =4ft
36ft=12 yd
2.5m=250cm
1000mL= 1 L
Explanation
if 1cm=10mm then 5cm=?
5×10=50mm
if 12 in =1ft then 48in=?
48/12 =4 ft
if 1m=100cm, then 2.5m=?
2.5×100= 250cm
and when know from capacity that 1000mL is equivalent to 1 liter.
The main purpose of a buffer solution is just to resist the change in pH so that the pH of the solution won't be much affected when we add an acid or base into it. The added acid or base is neutralized.
