Questions: Travel

I'm planning to fly from Rome to Malta for a couple days, and I was curious if I'll have to clear customs in Malta again, since I'll already have a Schengen stamp issued in Italy?

I did fly from Denmark to Poland once after leaving the airport to sight see, but that was almost 10 years ago, and I don't remember if I had to go through customs in Poland again or not.

I have an American passport.

Both my father and I lived in Missouri (pronounced Missourah) while going to college. He spent 4 years there in the 80’s, while I only lived there for the first semester and a half of freshman year (in 2020-2021). Both he and I drawl (speak with a “southern” accent) occasionally, but our normal accent is Pacific Northwestern. Is this a thing that happens, exclusive to the southern Midwest, exclusive to Missouri, or is it lead exposure, seeing as we lived in the same house with the same pipes?

The Arctic is characterized by cold winters and cool summers. Its precipitation mostly comes in the form of snow and is low, with most of the area receiving less than 50 cm (20 in). High winds often stir up snow, creating the illusion of continuous snowfall. Average winter temperatures can go as low as −40 °C (−40 °F), and the coldest recorded temperature is approximately −68 °C (−90 °F). Coastal Arctic climates are moderated by oceanic influences, having generally warmer temperatures and heavier snowfalls than the colder and drier interior areas. The Arctic is affected by current global warming, leading to Arctic sea ice shrinkage, diminished ice in the Greenland ice sheet, and Arctic methane release as the permafrost thaws. The melting of Greenland's ice sheet is linked to polar amplification.
