Question

Give reasons for the following:
Basic lava cones are broader than Acid lava cones.

Answer 1

Basic lava cones are formed by liquid lava which expands and covers a large area while the Acid cones are formed by solid material e.g. ash cinders etc which heap up but do not cover large area and form a high conical hill as compared to broad and low volcanic deposits on the surface.

Answer 2

Basic lava cones are broader than the Acid lava cones because basic lava is very fluid and flows easily for a great distance before it solidifies whereas acid lava is highly viscous and flows only for a short distance.
