Answer:Terrarium is actually an artificially made greenhouse glass container where sunlight easily passes through and we give other necessary objects for the plant growth inside the glass container. And our earth is very similar to the terrarium, our mother nature gives all the necessary objects for plant growth. A terrarium is different however, because in a terrarium there are glass walls that collect the moisture and let it drop back down in smaller quantities.

Explanation:
The pH scale stands for the power or potential of hydrogen. It measures how acidic or basic a solution based on the concentration of hydrogen ions and a scale from 1 to 14.
This scale is unique because it is logarithmic. So, every time the pH changes by 1 on the scale, the actual concentration of the solution increases or decreases by a tenfold.
So, a solution with a pH of 7 is ten times more acidic than a solution with a pH of 8. This can be translated to:
The black coffee has a pH of 5 and the hand soap has a pH of 10. We want to find how many times more acidic coffee is, so we subtract 5 from 10 and get 5. The difference in pH is 5.
Coffee is <u>10⁵ or 100,000 times more acidic than hand soap.</u>
Radio telescope picks up the radio spectrum of electromagnetic waves from celestial bodies (just like telescopes like the Hubble pick up visible light – only that radio waves are invisible to our eyes). They are therefore used to detect objects in space that produces radio waves. Examples are quasars and pulsars. Radio telescopes also enable astronomers to be whats beyond gas and dust in space that blocks out most of the visible light spectrum.
