All over. Sorry, but this question cannot be answered because it
is too vague. There are many, many different kinds of lizards, and
they come from virtually every corner of the planet. Where they
come from depends on species.
No. Lizards and dinosaurs came from separate branches of
reptiles. Lizards are in a croup called lepidosaurs, which also
includes snakes and the tuatara while dinosaurs were archosaurs, a
group that also includes crocodiles and alligators.
Blizzards, like other storms, come in many different sizes, so
its impossible to say how much land a blizzard. It may cover a
fairly small area, but often a blizzard covers a wide section of
land and may stretch out for miles.
Komodo dragons are lizards. They are not descended from
dinosaurs. Lizards come from the lepidosaur branch of reptiles
along with snakes, which are descended from lizards, and the
tuatara. Dinosaurs are from the archosaur branch along with
crocodiles and the only living dinosaur descendants, birds.
