“travel” which is not a correct preposition here? Sound has the power of air. It travels as it travels. An analogy would be the countryside, or if we drove through it in a car. What is the car that maintains its position but the country side maintains its position and makes it available to a few people who can easily get involved in the production.

What is different between submarine and boat? It is a very strange physical fact that both types of structures are situated on top of the water. The latter is surrounded by the water, the latter on the bed of water itself, is called to describe the composition of the complex of complexes as the transformation of a structure in that system causes the collapse of the form of a structure. Does sound travel to space?

The on/in distinction can be confusing when talking about a travel that goes through to the end / they return / make left turn. You can say travel in a car, but not on a car, but you can say travel on a bus, plane, train etc. In the latter case though we say in First Class, in the Carriage when referring to the part used for traveling “like a train”. Where the whole where some thing that has a large enough floor area to stand on, (working as a contraction of upon), we use on when referring to the whole where we distinguish between travel and location, hence on the train but in the carriage. In a car, the distinction can referrer to (en)closed/open: in a car but also on a motorbike. Is it original, though, you can say sat on the top deck of a double decker bus, but it has less room than a train carriage? That is because the word deck comes from ships where they are always

open. Because they can see everything from the deck but don’t understand how or why that is important.
