Gas particles are separated far from other gas particles, therefore, they can move freely and can be compressed and can be filled in different shapes of container, unlike solid, where the the particles are close and attracted to each other closely, thus they cannot fill a container or even be compressed because there’s no space between the particles.
Also, gas particles move a lot faster than solid or liquid particles, as said above, they have a lot more space to move around.
Water<span> boils when the molecules are able to overcome the vapor </span>pressure<span> of the surrounding air to move from the liquid phase to the gas phase.</span>
The heating of the troposphere<span> is </span>caused<span> by convection currents. Convection currents are created when the sun warms the air currents at the planet's equator to a greater degree than it does at the planet's poles.
Hope this helps you, and happy studying~!

Mammals do; I'm in my science class
The jet stream brings down colder air from the north into the southern regions of the United States so B . southeast I think.
