Answer: The federal government owns roughly 640 million acres, about 28% of the 2.27 billion acres of land in the United States. Four major federal land management agencies administer 606.5 million acres of this land (as of September 30, 2018). They are the Bureau of Land Management (BLM), Fish and Wildlife Service (FWS), and National Park Service (NPS) in the Department of the Interior (DOI) and the Forest Service (FS) in the Department of Agriculture. A fifth agency, the Department of Defense (excluding the U.S. Army Corps of Engineers), administers 8.8 million acres in the United States (as of September 30, 2017), consisting of military bases, training ranges, and more. Together, the five agencies manage about 615.3 million acres, or 27% of the U.S. land base. Many other agencies administer the remaining federal acreage.
Explanation: Pursuant to the Property Clause of the United States Constitution (Article 4, section 3, clause 2), the Congress has the power to retain, buy, sell, and regulate federal lands, such as by limiting cattle grazing on them.
 
        
             
        
        
        
Romanesque architecture is obsessed in semi-circular arches,
massive walls, barrel wall roofs (barrel vault) and decorative arcades
(succession or arches on a walkway). It is markedly different from Gothic
architecture, which is characterized by use of pointed arches. If you are
thinking about fairy-tale castles and stuff, you are probably looking at some
elements of that architecture. Romanesque architecture flourished approximately
6th to 11th centuries, and it is widely adopted by
castles, monasteries, and churches. It got its name probably because of the
arches, which is a feature typical in Ancient Roman architecture. Actually, the
word Romanesque was coined in the 18th century.  
 
        
             
        
        
        
When a country gifts some of its land to other country, it is generally not a quiet surrender.
<u>Explanation:</u>
When the government of the country gifts land to some other countries as a result of some privileges or some return of favor, it is not necessarily a surrender done by the country to other country. It might be a gift of real estate to that country.
It is known as the and grant where land is granted to that country. They are given to individuals or the countries to develop the land which is unused especially in the underpopulated countries.
