What type of volcano forms as lava spreads over a long distance, and then cools and forms a hill that slopes gently? fissure composite cinder cone shield

The correct answer is ''shield volcano.''

Explanation:

Shield volcanoes are those whose diameter is much greater than its height. They are formed by the successive accumulation of very fluid lava flows. So they are of considerable height and slight slope. Its topography is smooth and its top forms a poorly defined depression. Lava ejected during an eruption is largely basaltic in composition and has a very low viscosity (it is liquid). Because of this, lava flows easily and spreads over a large area. Shield volcano eruptions generally involve lava that travels great distances and spreads out in thin layers. As a result, the volcanic mountain that is built over time by repeated lava flows has a broad, smooth profile leading away from a bowl-shaped depression at the top known as a caldera.
