There are six changes of phase that substances go through:
<span></span>→ Freezing: liquid to solid.
→ <span>Melting: solid to liquid.
</span>→ <span>Condensation: gas to liquid.
</span>→ <span>Vaporization: liquid to gas.
</span>→ <span>Sublimation: solid to gas.
</span>→ <span><span>Deposition: gas to solid.

The last bit of your question, YES these domestic animals have a huge ecological importance! Especially if you released them into the wild.
<span>When I first read the question, I wasn't so sure about this. I figured they would probably just wander around for a while, possibly a few months or years, and then die out little by little as they competed for food and fell to predators. </span>
<span>However, in the meantime they would likely eat everything, and then attract large numbers of predators, who would then have many babies. </span>
Thin atmosphere with low oxygen and carbon dioxide levels
Possibly because preditors hiding in sand
