If my friends and i came to a strange planet the first 3 enviromental factors I would look for would be a delta because deltas gives flate wide areas wich has rich soil wich makes the plants grow faster and fresher and it gives fresh and clean water to drink, wash our clothes. The second enviromental factor i would look for would be a river because you can clean yourselves , bath and find fish to eat. The last of the 3 envirtomental factor would be a Valley because it is beautiful it has alot of , plants and water. Valleys are on top on mountains witch makes it a good view over a big area of land. Thats good because then we could see if any one was planning to attack us.
