The United States is a vast country and it has all sorts of relief forms, but it can generally be divided into few relief regions that have similar characteristics.
Explanation:
The United States is an enormous country, occupying territory in North America that stretches from the Pacific Ocean in the west, to the Atlantic Ocean on the east, and from the Great Lakes in the north, to the Gulf of Mexico in the south, plus having some territories that are not attached. In this vast territory, there are all sorts of minor and major relief forms, which makes this country very interesting for the geographers.
Some areas are very low, some very high, there are numerous mountains ranges, lowlands, and plateaus. There are several orogenic processes that took place and formed big portion of the relief forms. What is interesting for relief in the United States is that it can be divided from east to west, in a meridian manner, as all the major relief patterns tend to have a roughly north to south direction.
The country can be divided though into several areas in accordance to the relief patters:
- Strip of coastal plains along the Atlantic coast
- Appalachian Mountain Range
- Plains
- Rocky Mountains
- Plateaus
- Cascades
- Strip of coastal plains along the Pacific coast

Answer:
True, members of the Wampanoag tribe helped the colonists survive.
Explanation:
When the colonists first arrived in what is now Massachusets, they didn't really know what they're facing and were simply not aware of the conditions in the area and how to survive long term. This was a big problem because the reason why they moved there was because of searching for new opportunities and by not surviving this wouldn't have happened, while the government had its goal on long term settlements through which it will increase its influence in the region.
The reason why the colonists, referred to as Pilgrims, survived were the members of the native Americans, namely the Wampanoag. The Wampanoag were friendly and they explained to the colonists what they can expect climate-wise, thought them about the characteristics of the land, introduced them to local crops and how to grow them so that they can feed themselves. This led to good and friendly relations between the two groups and the colonists survived and managed to remain in the area.
