Pressure varies from day-to-day at the Earthâs surface - the bottom of the atmosphere. This is, in part, because the Earth is not equally heated by the Sun. Areas where air is warmed often have lower pressure because the warm air rises and are called low pressure systems. Places where air pressure is high are called high pressure systems. A low pressure system has lower pressure at its center than the areas around it. Winds blow towards the low pressure, and the air rises in the atmosphere ...
A female cat can get pregnant when sheâs as young as 4 months old, unless sheâs been spayed to prevent that. Queens can keep going into heat every 2 to 3 weeks from the spring through the early fall, making them ready to reproduce more often than not. A catâs pregnancy lasts about 63-65 days.
