Question

a front refers to
the location where two air masses meet.
an air mass that extends across a large area.
a large body of air moved by global wind patterns.
a place on earth’s surface affected by uneven heating.

Explanation:

In meteorology, a front is defined as the boundary or location where two different air masses (with different temperature, humidity, etc.) meet. The other options: an air mass that extends across a large area describes an air mass itself, a large body of air moved by global wind patterns also describes an air mass, and a place on Earth’s surface affected by uneven heating is related to heat distribution causing wind/air movement but not a front.

Answer:

A. the location where two air masses meet.
