row 2: bad outcome more likely (large frowny face, smaller smiley face) 
prepare for the bad outcome while remembering that the future isn't certain and hope is justified

the corresponding box has a bunch of question marks and is marked "not applicable" (N/A)

Short hair and no hair are speaking. 
Short hair says "I need water, so I think I'll dig a deep hole and drink whatever liquid I find at the bottom."
No hair asks. "What will you do after ou drink it all? Dig another hole?"
Short hair responds "I dunno. Hopefully it magically refills itself or something."

Lower caption: It's ridiculous that wells work.

Single panel comic.

A pyramid with 5 tiers and some tiny people on the bottom for scale, one of which is gesturing at the pyramid. The tiers are labeled and have additional commentary on the side.

From the bottom:
1.  physiological needs (red X, provides basic shelter, but no food, water, heat, etc)

2. safety (green check, highly defensible)

3. belonging and love (red X, friends are worried about me)

4. esteem (red X, people seem less impressed by it than I hoped)

5. self-actualization (red X, honestly questioning my life choices here)

Lower caption: I built Maslow's pyramid thing, but it's a total ripoff-- it's only providing 20% of my needs.

Singel panel comic.

Short hair staring in front of a presentation. On the screen is a trajectory of a comet passing by the earth. The orbit of the moon is drawn around the earth. 

Short hair says "Astronomers initially said there was a one-in-6,000 chance that the newly discovered asteroid might "do something cool" in 2063, but further observations determined it will be "just a boring dot like all the others."

Title: How water filtration works.

There is a long snaking diagram of various apparatuses connected together. For the most part they are differently shaped little blobs with various ridges on them.

The input is well water, which goes through the pathway in the following order.
1. water softener (looks like a box of sand)

2. reverse osmosis

3. ultraviolet sterilization

4. autoclave

5. condenser

6. regular osmosis

7. x-ray sterilization (radioactivity symbol on this blob)

8. carbon filter (this is unusually long to make a turn in the snake)
8a. neutron source (this is attached to the carbon filter as a small sphere radiating wavy lines)
8b. activated carbon filter (this is the region of the carbon filter after the neutron source, there is no line to distinguish between the filters)

(alt-text continued in the next image)
(continued alt-text)

9. gamma ray sterilization (radioactivity symbol on this blob)

10. cosmic ray sterilization (blob has what looks like EeV gamma, which is taken to mean a quintillion electron volts)

11. electrolysis (H2O is being split into H and O)

12. two path ways, the upper is oxygen spallation where the O from the previous blob is turned into multiple H, the lower is just feeding through the H from the previous blob, the hydrogens all merge into one stream to continue

13. ionizer (H splits into an electron and a proton)

14. quark-gluon plasma chamber (electron and proton come together to make a quark-gluon plasma, which is a gassy blob)

15. hydrogenation (the quark-gluon plasma generates H)

16. nucleosynthesis (the H stream splits in two, the upper goes through a blob labeled P-P CN, comes out as He and C and then goes through a blob labeled Alpha and comes out as O, the lower stream just feeds through the H from the previous blob), the hydrogens all merge into one stream to continue

17. reverse electrolysis whose output is labeled "pure water"

18. a second input stream is labeled well water and joins the main stream at this point, the junction is labeled local minerals and probiotics added for taste and to support immune health

19. the output is labeled "to faucet"

(xkcd.com/2973)
(explainxkcd.com/wiki/index.php)

Single panel comic.

A row of three ferris wheels. There are teeny tiny figures at their bases for scale. The rim of the first wheel is connected to the hub of the second by a pair of thick straps. The wheel of the second is then connected to the hub of the third with another pair of straps. 

The cars no the first wheel are all upright in the usual position for a Ferris wheel. The cars on the second wheel are partially angled out as the wheel moves faster. 
The cars on the third wheel all have their bottoms in parallel with the wheel rim as it spins very fast.

Lower caption: the county fired me for adding a belt drive to the ferris wheels.

@xkcdbot I like the intertextuality reference to xkcd.com/303/ in the alt text!

If anyone tells me I should only use the term "intertextuality" for links between different works of literature, I'll reply that each xkcd comic is a piece of literature.

No hair is standing below two alien ships that look like flying saucers.

A voice from one of the ships responds "Yeah, but these reports describe fast-moving objects with capabilities far beyond anything we possess! It would be foolish not to investigate!"
