The research of Washington DC

       Today, we are going to research the capital of the United States. We will research in three different aspects: Geography, Climate and economy. I find some interesting information from wikipedia. 

        At first, we are talking about the geography of Washington DC. Washington DC is located  at  38°53′42″N 77°02′11″W. The geographical area of Washington DC is 68.3 square miles, 
and the area of the lands of Washington DC is 61.4 square miles. The other 6.9 square miles
 is water. It is located at the east coat of the United States. The earthquake activity of the district 
is low, but there are many earthquakes in Virginia , Maryland and many other surrounding countries. 

       Then, we are going to talk about the climate of Washington DC. Washington DC is in humid subtropical 
climate zone. It will also show us four distinct seasons. The spring and fall are warm, and the snow of winter 
has an average amount which is 15.5 inches.

       At last, we are going to talk about the economy of Washington DC. "Washington has a growing, diversified economy with an increasing percentage of professional and business service jobs.The gross state product of the District in 2010 was $103.3 billion, which would rank it No. 34 compared to the 50 U.S. states." This quote shows us that Washington DC has a very developed economy, even though it is not the most developed city of the U.S.

       In conclusion, Washington DC is worth to be a capital city. No matter geography, climate or economy, it is very good for people to live, and it can also become a symbol of the U.S.
