which type of volcanic mountain has wide, gentle slopes?\n\nrift\nshield\ncomposite\ncinder cone

Answer:

shield

Brief Explanations:

Shield volcanoes are formed by the eruption of low - viscosity lava that can flow long distances. This results in the build - up of broad, gently sloping sides. In contrast, cinder cone volcanoes have steeper slopes formed from the accumulation of fragmented volcanic material (cinders). Composite (stratovolcanoes) have steeper slopes due to the alternating layers of lava and ash. A rift is not a type of volcanic mountain but rather a linear zone where the Earth's crust is being pulled apart.
