Since i live in it: America
IF we go by the British:
first they landed at Roanoke and Jamestown. Jamestown was successful.
#1 expansion: colonists were given the right to move all the way up to the Appalachian mountains.
#2 expansion: When the US bought the Louisiana purchase
#3 expansion: The successful revolt of the Texans
#4 expansion: Mexico succeeds most of their northern lands.
#5 expansion: Gadsen purchase: brings the US mainland's border too today.
Many difficulties include:
1) no good maps
2) hard to make livings
3) Indians, robbers, etc
4) diseases, exposure, etc
5) ran out of supplies
6) broken down wagons, etc (if they took the boat to California, it will be: traveling for a long time, etc)
7) etc etc
hope this helps

What u said i don’t understand
Ring of Fire, also called Circum-Pacific Belt or Pacific Ring of Fire, long horseshoe-shaped seismically active belt of earthquake epicentres, volcanoes, and tectonic plate boundaries that fringes the Pacific basin. For much of its 40,000-km (24,900-mile) length, the belt follows chains of island arcs such as Tonga and New Hebrides, the Indonesian archipelago, the Philippines, Japan, the Kuril Islands, and the Aleutians, as well as other arc-shaped geomorphic features, such as the western coast of North America and the Andes Mountains. Volcanoes are associated with the belt throughout its length; for this reason it is called the “Ring of Fire.” A series of deep ocean troughs frame the belt on the oceanic side, and continental landmasses lie behind. Most of the world’s earthquakes, the overwhelming majority of the world’s strongest earthquakes, and approximately 75 percent of the world’s volcanoes occur within the Ring of Fire.
