Answer:
A hot air balloon uses a burner to heat up the air inside the balloon. The burner is usually fueled by liquid propane. The burner mixes the fuel with air and ignites the mixture, which creates a flame directly underneath the bottom opening of the hot air balloon. Once the air inside the balloon begins to get warm, the balloon will rise. The pilot controls the balloon’s altitude by releasing hot air from a vent at the top of the balloon, releasing the warmer air causes the balloon to descend.

Explanation:
how is geologic activity & geologic structure similar?
Explanation:
Geological activity determines geological structures. The prevalent types and forms of tectonic working in a place will control the form of structure that can be found in a terrain.
In volcanic region, it is common to see volcanic structures of different types such as calderas, strato-volcano etc. These structures are formed by the volcanic activities. Also, in a karst topography, we find sink holes, stalactites and stalagmites etc. due to the nature of the geologic activities going on. Some sedimentary rocks shows cross bedding due to the environment where they form.So, geologic activities controls the structure found in an area
