The correct answer is option 1: Shield volcano.

Individual lava flows from a volcano are typically not very thick, only a few feet in height. However, over a long period of time, multiple lava flows can accumulate and build up a volcano.

Option 2: Composite volcano, also known as stratovolcano, is not the correct answer. Composite volcanoes are formed by alternating layers of lava and ash, and they typically have a steep and symmetrical shape.

Option 3: Strato-volcano is another term for composite volcano, as mentioned earlier. So this option is not the correct answer either.

Option 4: Cinder-cone volcano is also not the correct answer. Cinder cones are small, steep-sided volcanic landforms that are formed from ejected fragments of lava, called cinders.

Therefore, the correct term to describe volcanoes that are built up over time by repeated lava flows is shield volcano, which is option 1.
