Hi!
Our sky is blue because air molecules will span out <em>blue </em>light from our sun more than <em>red </em>light from our sun.
If you look at the sun, you'll see orange and red colours due to the fact that the suns blue light has already been disbursed away from our line of sight.
Hopefully, this helps! =)
Answer:
By measuring the quantity of unstable atoms left in a fossil and comparing it to the quantity of stable daughter atoms in the fossil , scientists can estimate the amount of time that has passed since that fossil formed.
hope this helps !
The answer is option number 4. If you do the math, the sides are simply scaled by 3.
<span>Carbonic acid formation
CO2(g) + H2O(l) ----> H2CO3(aq)
Dissolving of calcite
CaCO3(s) + H2CO3(aq) ----> Ca(HCO3)2(aq</span>
E.) Mesosphere, Asthenosphere, Outer layer
Unfortunately there is no standard terminology for three mantle layers.
<span>I can be sure that "ionosphere" and "thermosphere" refer </span>
<span>only to atmospheric layers, so you can rule out A, B, and D. </span>
<span>"Mesosphere" may be used to refer to an atmospheric layer, </span>
<span>but is also often used to refer to a mantle layer. </span>
<span>
, </span>
<span>so I'll go with E even though I don't like it much. </span>
<span>I guess what is meant by "outer layer" is the part of the lithosphere </span>
<span>that does not match crustal composition.</span>
