It lowers, not sinks.
No.
As you climb a mountain the air gets colder.
an air conditioner because it warms up to make cold air
Colder air is denser than warmer air, causing it to sink and create higher pressure at the surface. This is because the molecules in cold air are packed more closely together, exerting a greater force per unit area. This explains why air pressure tends to increase when the weather gets colder.
Uhm, it gets colder of course....
As you get higher the air is thinning not expanding.
in the lower atmosphere the air gets colder with increasing altitude.
Yes, cold air is denser than warm air, so it tends to sink towards the ground. This is why you may notice colder temperatures closer to the ground, especially at night.

When the air gets colder, snowflakes can form as water vapor in the air condenses into ice crystals. These ice crystals then join together to form snowflakes. Colder temperatures allow for the formation of more complex and well-defined snowflake shapes.
It depends on several things, but usually it's forced upwards. As it rises, the air gets colder. As it gets colder the moisture in the air condenses, first into clouds, then possibly into rain or snow.
It is cold because as you get higher in the air it gets colder
