One area of Canada has a
weaker gravitational pull than the rest of Earth.
A
swath of land in northern Canada was found back in 2007 to have unusually low
gravitational pulls. The reason for this, according to Science, is because nearly 20,000 years
ago, the weight of massive ice glaciers "caused some of the rock beneath
to compress and sink, and in the process displace the underlying semifluid
mantle."
