A cinder cone volcano....found in my 8th grade science book page 136(:
It is a Cinder Cone Volcano
It's a shield volcano. Curtesy of a quick google search [from geography.learnontheinternet.co.uk] Shield Volcanoes Eruptions are typically non-explosive. Shield volcanoes produce fast flowing fluid [lava] that can flow for many miles. Eruptions tend to be frequent but relatively gentle.
The type of volcano is the shield volcano. Shield volcanoes can be found in Hawai'i.
Generally, when a volcano produces a gentle eruption the lava has a very low viscosity (it is very runny). This allows the lava to spread out quickly after it has exited the volcano but before it cools and hardens. This means that the lava will be able to spread further from the eruption site and thus gentle slopes are created. In a strong eruption, lava with a higher-viscosity is thrown out along with some rock fragments, this lava cannot flow as far away before it cools and so the volcano has steep slopes. Hope that helps!
spelistic
This is known as a volcanic vent.Gas and lava exit a volcano are through a volcanic vent or fissure and cool rapidly at the surface. Eruptions can be fluid or explosive.

a shield volcano
The magma that can produce a violent eruptions is those rich in silica,fluid,iron, and forming shield volcano.

shallow-sloping sides its huge in size and is built by many layers of runny lava flows gentle sloping caused by the very fluid
The Columbia Plateau flood basalts were very fluid eruptions along lengthy fissures. Being very fluid, they didn't pile up, but rather flowed outward in broad sheets. Volcanic peaks are formed around central vents. As the lava pours out it solidifies generally not very far from its source, stacking up layer upon layer.
Cinder Cone also known as Ash-cinder Volcano · Cone-shaped volcano · Steep side · Lava flows through a single vent · Usually a bowl-shaped crater at the top · Erupts into the air · Lava fragments forms cinders · Examples - Mount Tabor, Mount Zion Composite or Strato Volcano - most common volcano · Steep-coned volcano · Viscous slow moving lava · Emits gases, ash, pumice, silica lava · Eruptions can cause deadly mudflows · Examples: Mount St. Helens in Washington State, USA; Mount Pinatubo in the Phillippines Flood or Plateau Basalt also known as Fissure Volcano · Very liquid lava · Flows are widespread · Gentle basaltic slope of lava · Example: Columbia River Plateau Lava Dome · Rounded volcano · Lava barely flows · Example: Mount Pelee in Martinique Rhyolite Caldera Complex also known as Caldera Volcano · Most explosive volcanoes · Large volumes of magma erupts at once · Volcano collapses after explosive period · Example: Yellowstone, Wyoming, USA; Lake Taupo, New Zealand Shield Volcano · gently-sloping volcano · emits mostly basaltic (fluid) lava · gentle eruptions · explosions are minimal · can be very large · example: Mount Kilauea in Hawaii
The shape tells a geologist how viscous (thick and sticky) the lava was. A taller volcano, such as a cone, was formed by thicker lava; a low volcano, such as a shield volcano, was formed by very runny lava.
There are three kinds of cone volcanoes shield cones, composite cones, and cinder cones. Shield cones have very fluid lava. They erupt with a quiet lava flow. An example of a shield cone volcano is Mauna Loa. A shield cone is pretty much a little dome that has been flattened. Composite cones have sticky lava and rock bits. They have the most explosive eruptions An example of a composite cone volcano is Vesuvius. Composite cones are steep at the top but gentle at the bottom. Cinder cones have cinders. They have explosive eruptions An example is Paricutin. A cinder cone is very steep.
