Indeed. One of the major differences between our planet and Mars: The later has no molten core, and no magnetic field, thus most of its atmosphere escaped over time. While some is still left, it's not very dense. A 150mph hurricane on Mars is very different from one on Earth.

I am always amazed at our tiny little planet hurtling through space with its micro thin layer of atmosphere barely held in place.
Not wishing to start an argument here, but "micro thin layer of atmosphere" more aptly describes Mars, not Earth. So does "barely held in place." After all, Earth still has a dense enough atmosphere for us to breathe. Even to 14,000ft. After billions of years. That's pretty robust to me.
It is in a near perfect balance though to sustain life. Gravity, atmospheric pressure, humidity, density at sea level, and enough oxygen to sustain life, but not enough to turn us into a fireball when a volcano goes off.
