I believe I read this work in the 70s. As I recall it was one of several short works in paperback, US printing.
They story has a dialog between some astronauts. They are discussing the possibilities of life on the planet they are going to. There are significant differences in temperature between their planet and the one they are going to.
Seems like there was something about the highly corrosive atmosphere of the destination planet (20% oxygen), they land in level area which turns out to be a grass field or meadow that catches on fire from the heat of their ship.
The idea of combustion/fire in the environment was incomprehensible to the astronauts, not sure if was do to lack of Oxygen on their home world, or because they lived under water.
