I believe the theme to be:
Super Mario 64
As suggested by previous answers:
Each image represents a world in the game.
Shifting Sand Land -- the image may represent the process of sand dune formation
Lethal Lava Land, a world located upon a lava ocean/lake not unlike what is pictured here
Cool, Cool Mountain, a snow/ice level with a central peak
Tall, Tall Mountain, a level centered entirely on a (you guessed it) very large, tall mountain
Could be Dry Dry Docks based on the water and what appears to be a dock in the background. (EDIT: Whoops, mixed up my words! s/Dry/Dire)
Jolly Roger Bay, due to the presence of a pirate ship upon water, which are both prominent in this level.
Could be Wet Dry World, as the vacuum pictured would work in either case.
Tick-Tock Clock (Tick, tock, it's a clock!)
Looks like a shimmering figure in an entryway...so perhaps Hazy Maze Cave?
Tricky one, but I'm thinking Bob-omb Battlefield...one of the castle's stars is guarded by a big Chain Chomp, which barks like a dog.
Update to 10.:
Credit to @Pugmonkey in a comment to Joe-You-Know's answer for identifying the dog as "Boo", this one is probably Big Boo's Haunt, although it features a ghost, not a puppy. :-)
Taking a super wild guess here, but is it:
Here is my (quite flawed, I think) logic:
According to the Wiki, these are the worlds in the game:
Spiral Mountain | Hub World | Gruntilda's Lair | Mumbo's Mountain Treasure Trove Cove | Clanker's Cavern |
Bubblegloop Swamp | Freezeezy Peak | Gobi's Valley | Mad Monster
Mansion | Rusty Bucket Bay | Click Clock Wood
Alot of these worlds resemble the images in the OP post. There's the obvious mountains/hills etc, but there is also the Large Clock which matches with Click Clock Wood.
I also looked into a couple of spin offs of the game, trying to see if I can match something else up.
It's probably a video game, and probably refers to the worlds in the game.
(ALSO, I Reverse-Image-Searched the first image and Google Said it was about "deposition features of wind")
I think it is:
Castle Crashers (or The Benemoth itself)
The answer is a game and the images are worlds in a game.
Most of this images are levels in the game castle crashers. Some of these I didn't find but I found the levels
Pirate ship level
Probably a stretch but the game Battleblock theater (The same creators of Castle Crashers has a Vacuum
Battleblock theater also has time trial maps
Pazzo looks like a shiba inu
I am not completely satisfied with this answer, but it fits some of the images:
The theme is:
Agrabah. The image is the mechanism of sand dune formation / migration.
The North Mountain from Frozen (actually the Matterhorn)
Olympus Coliseum - the largest mountain is Olympus Mons on Mars
The Jolly Roger
The Clocktower (Big Ben) in Neverland World
The Cave of Wonders
Monsters Inc World (the dog pictured is Boo, the self-described "cutest dog in the world"). This could also be the Pride Lands since the dog looks vaguely like a lion
I think it is:
The Super Mario Games/World
Clearly a sand level, obviously World 2 in most games.
Clearly a lava level, most likely found in World 8 in most games.
The ice/snow levels found in World 5.
Possibly Super Mario Galaxies, as it features more worlds (you show a mountain of Mars).
Dire Dire Docks in Super Mario 64 or maybe Super Mario Sunshine and Isle Delfino
Pirate Land featured in Mario Party 2
Luigi's Mansion, with his Poltergust
Maybe referencing Mario & Luigi: Partners in Time
Any of the tunnel or cave levels.
@Pugmonkey, boo the cutest dog in the world. So this is either King Boo, or many of the boos in the Super Mario World.
