How ‘Snowball Earth’ volcanoes altered oceans to help kickstart animal life

"The resulting continents were clustered near the equator where there are higher temperatures – resulting in increased evaporation of water from the oceans"

What am I missing here? This makes no sense to me. If the continents are clustered closer to the equator, then the oceans are at disproportionately higher latitudes, resulting in less solar radiation reaching them and making for less evaporation.

Also, the link for "flush dissolved minerals via rivers into the oceans" doesn't work.
