Hot spot is a portion of the Earth's surface that may be far from tectonic plate boundaries yet experiences volcanism due to a rising mantle plume or some other cause.

Explanation:

Volcanism refers to intrusion of magma into the earth's crust and extrusion of magma into the earth's surface. It mainly takes place when two plates collide with each other in the destructive plate boundary but sometimes without plate tectonic activity volcanism occurs due to a rising mantle plume in the hot spot.

Hot spot is a place in the earth's surface from where lava comes out from astheonosphere, the upper part of mantle. In excessive temperature in the earth's interior several block of earth's crust melts there and forms volcanism. For e.g. Hawaii, Iceland volcano.

because of its location and commercial importance, atlanta was used as a center for military operations and as a supply route by the confederate army during the civil war. therefore, it also became a target for the union army. general william tecumseh sherman and his troops captured the city in 1864.
