The series of events in a story that develop a problem for the characters, lead up to a climax and provide a resolution to the problem is termed as rising action.
Explanation:
After the introduction of the characters and the setting, rising action begins. It is the series of events that allows conflicts to arise. As the characters face those conflicts, trying to solve them, tension and suspense build. When tension reaches its peak, it mean the plot has arrived at the climax. In other words, rising action is the plot itself leading to the climax.
