Answer:
1.Changes in weather are primarily caused by changes in the atmosphere's temperature, air pressure, and humidity
2.The effects of barometric pressure on water chemistry and meteorological conditions are significant. When contrasted to lower air pressure, higher pressure allows more gas, such as oxygen, to dissolve in water. At sea level, for example, more oxygen is dissolved in water than at high altitudes.
3.Fronts of cold weather normally migrate from the northwest to the southeast. The air behind a cold front is colder and drier than that which before it. Temperatures can drop more than 15 degrees in an hour when a cold front moves through. When a warm front sweeps through, the air gets considerably warmer and more humid.
4.An air mass has roughly the same temperature and humidity. Air masses form over regions where the air is stable for a long enough time. The air takes on the characteristics of the region. Air masses move when they are pushed by high level winds.
5.The Philippines is extremely sensitive to the effects of climate change, which include sea level rise, an increase in the frequency of extreme weather events, rising temperatures, and excessive rainfall.
