Environment Book Series
Frostburn focuses on taiga and tundra environments as well as supernaturally cold planes. On the crunch side, it adds a bunch of ice themed abilities.
Mechanically it is notorious for introducing the Shivering Touch spell, which does 3d6 (~10.5) points of dexterity damage that stacks with itself for a third level spell. This spell is absolutely bonkers since enemies rarely have that high a dexterity score, and even ones that do will rarely survive multiple hits from it.

Sandstorm focuses on badlands, desert, and wastelands. Unlike Frostburn, there's not that much fire or extraplanar material. On the crunch side, the book adds a bunch of sand based stuff and heat themed abilities that focus on impeding and exhausting enemies instead of just making them burn.

Cityscape focuses on urban adventures. It includes how to distinguish cities from each other, locations within cities, who lives in cities, and how the surrounding area effects a city as well as what to do on an "adventure" in the city. On the mechanical end, there's intrigue focused spells and character options.

The most notorious crunch is the Primary Contact feat, which gives a free skill rank even if would put above the maximum for your level. This is the lone early entry method in 3E that allows bypassing skill requirements, even if it only reduces them by 1. Since it has to come at a feat level and only advances one skill, it's limited in use to classes that require specific number of skill point (generally 7 or 10) in one skill or in a build that somehow gains a general bonus feat. It's more flexible when retraining rules or the (far cheeseier) embrace/shun the darkness loop are abused to allow it to be taken at any level.
Dungeonscape focuses on subterranean adventures, including those in stereotypical dungeons. There is also advice to building better dungeons.
Uniquely, Dungeonscape has no new PC races and only two new monsters - both of them recreations of obscure old-school beasties; the Ascomoid (a giant killer puffball fungus) and the Rot Grub Swarm. It does have five new templates for monsters (Acidborn, Dungeonbred, Guardian, and Hivenest for general monsters, and Sentry Ooze for slimes). It does have a new standard class in the Factotum, though.
