The geological feature responsible for the volcanic activity in this part of the world is the convergent tectonic boundary between the North American tectonic plate and the Pacific tectonic plate.
The Aleutian Islands are part of the so called ''Ring of Fire''. This means that they are part of the most active volcanic chain in the world. This is due to the convergent boundaries between the Pacific tectonic plate from one side, and the North American, South American, Eurasian, and Australian tectonic plate from the other side. The Pacific plate is submerging bellow all of them, and this contributes to the release of lots of magma and pressure towards the surface of the Earth, thus creating volcanoes in close proximity to the tectonic boundaries.

Explanation:
The Chesapeake Bay is the largest estuary in the United States. The Bay is located in the Mid-Atlantic region and is primarily separated from the Atlantic Ocean by the Delmarva Peninsula with its mouth of the Bay at the south end located between Cape Henry and Cape Charles. With its northern portion in Maryland and the southern part in Virginia, the Chesapeake Bay is a very important feature for the ecology and economy of those two states, as well as others surrounding within its watershed. More than 150 major rivers and streams flow into the Bay's 64,299-square-mile drainage basin, which covers parts of six states and all of Washington, D.C. / District of Columbia.
