| New lake regions, flattening mountains, changing the height of mountains (and thus their weather and flora/fauna), carving out massive gulfs or bays from the continents, shifting islands north or south (thus altering their weather and colonization patterns) and so much more. |
I'll break this out to explore some implications. At the larger scales
of these kinds of changes, they might generate a group of tangents that spreads, depending on the time of divergence, between the Historical and Biological divisions. If Earth has other typical landforms worldwide due to differences in the planet's size, composition or orbit, canonically that's a Cosmological tangent.
Differences might occur due to the semi-random action of faults and volcanic hotspots over time, or as a secondary attribute, might have more Fantastic causes.

- Different forms of Antarctica, Kerguelen, India: the Lemurian Cluster. This also considerably alters regional climate if the Himalayas are differently shaped or absent.
- Sunda, Doggerland, the Black Sea: areas sunken under the sea in our parallel that are dry land, or became submerged at a different time
- Iceland (more than its size and population would suggest) or other locations formed on the mid-Atlantic ridge as an Atlantis-Hybras Cluster
- various cities historically destroyed by earthquakes and volcanoes

One that could have a significant impact is a large island on the Mid Atlantic Ridge off of the Western Coast of Africa, where hurricanes form. There still would be cyclonic storms in the Atlantic, but they would be less powerful.
And if Atlantis sinks, then North America suffers for it. Especially if the sinking creates an extra warm spot that would make the storms stronger than in the real world.
Another is carving out Saharan Africa. If the Med Sea is that wide, then contact and conflicts with Europe would be less, at least before the Age of the Sail. Rome would spend more resources on Europe and possibly survive much longer.

As mentioned, lakes (including large sizes), river channels and shipping routes are pretty strongly affected by random events.

Sure, if Egypt and Carthage didn't exist (put that way, the effect is obvious) and access to central Africa was easier, the history of the Mediterranean - Greece and Phoenicia, too - would have been entirely different. Rome's a reasonable settlement site, but doesn't have obvious critical advantages over many others in northern Italy, Spain, the Balkans and so on, and the culture of a Mediterranean power there or elsewhere would be unrecognisable.
