b. a tall volcano that is covered in hardened

A cinder cone is a short, steep volcano that blasts out

pyroclastic material.

Explanation:

A cinder cone is basically a sharp conical hill which consist of a loose pyroclastic fragments that are being formed on the sides on volcanic vent.

Simply think of a steep volcano and how it acts when it blats out, this is what cinder cone is. When the lava is blown out in a very violent manner, it breaks in to very small particles that can be addressed as cinder. Almost all the cinder cones are made up of pyroclastic substance.

starchy vegetables are high in carbohydrates.

starchy vegetables contain more carbohydrates than non-starchy vegetables.

explanation:

there are two primary categories of carbohydrates, essentially differentiated on the basis of their carbohydrate content (which is in the form of starch - a complex carbohydrate):

those vegetables which contain little amounts of starch are termed as non-starchy vegetables, and some examples include: artichokes, broccoli and bean sprouts.

vegetables high in their starch content are distinguished as starchy vegetables, and some examples include: potatoes, chickpeas and corn.
