Why do air masses move west to east?

Air masses move from west to east primarily due to the Earth's rotation. This rotation causes the Coriolis effect, which deflects moving air to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. As a result, air masses tend to move from west to east on a global scale.


Why does cold air always chase warm air?

Cold air is denser than warm air, so it tends to sink and move underneath the warmer, lighter air. This creates a pressure difference that causes the cold air to push the warm air out of the way as it moves. This process is known as cold air chasing warm air.


What causes air to be denser near earths surface?

Air near Earth's surface is denser due to the weight of the air above it pressing down, creating higher pressure. Additionally, higher temperatures near the surface cause air molecules to move more rapidly, spreading out less and increasing air density.


How do pressure systems move?

Pressure systems move due to differences in air pressure. Air flows from high pressure areas to low pressure areas in order to equalize the pressure, creating wind. The movement of these pressure systems is influenced by the Earth's rotation, which causes them to spiral and move in a particular direction.


Air temperature increases density?

As air temperature increases, the air molecules gain more kinetic energy, causing them to move faster and spread out, decreasing air density. Conversely, when air temperature decreases, the air molecules slow down and move closer together, increasing air density.
