Why are some kinds of volcanoes cone-shaped and others shield-shaped?
Cone-shaped volcanoes have thick lava that slowly oozes out forming a hill, while shield-shaped volcanoes have thin lava that is runny and spreads further.
Because there are bigger cracks in the earth under the cone-shaped volcanoes.
How can you figure out if a volcano makes felsite or basalt rocks?
