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

The closest answer to what I remember is B) 1191
Remove Excess CO2 via scrubbing
Replace energy from fossil fuels with geothermal solar energy.
Sequester released CO2 before it reaches earth's atmosphere
The topmost layer of the earth (aside from the atmospher) would be the crust. It is made up of tectonic plates that move in different directions. The collisons and abrasions made by these plates sliding and crashing into each other means that mountain ranges pop up like wrinkles, and continents can move around over time. This happens over millions of years.
good luck !
To survive they have made modified leaves into spines to prevent excessive loss of water from the plant body and deep roots to get to a water source.
