Basic volcanic lavas are those which have a low silica (45 - 52%) and a high iron and magnesium content. The term "basic" in this context is somewhat outdated. Modern scientists generally prefer to call such lava mafic.
The cone on a volcano is basically the tip of the volcano where the lava spurts out from.(I think)
A cinder cone volcano typically has basaltic lava, which is low in silica content and flows easily. This results in the formation of steep-sided cones made of mostly cinders and volcanic ash.
a dome volcano is not the same as a cone volcano. a dome volcano is a type of volcano, is a roughly circular mound-shaped protrusion resulting from the slow extrusion of viscous lava from a volcano. Usually it extrudes very slowly, but constantly. A cone volcano has an appearance of an upside-down funnel with a hole in the top which the lava shoots out of.
The Arenal Volcano is a cinder cone volcano
Lava. When the lava comes out of the volcano, gravity pulls the lava down the cone of the volcano, and depending the the viscocity of the lava, it forms a 'cone' or 'shield' as it cools. Thinner lava forms a shield volcano; thicker lava forms a steeper cone shape.

parasitic cone
A volcano can be a cone-shaped mountain that is built from layers of lava.

the composite cone
Not acid lava, basic magma.
A composite cone is the type of volcano that consists of layers of lava flows and pyroclastic material. A stratovolcano is an example of a composite cone.
