When ash, cinders, and bombs build up in a steep pile around a volcano’s vent, the result is a a. cinder cone volcano. b. shield volcano. c. composite volcano. d. dormant volcano.

When ash, cinders and bombs build up in a steep pile around a volcano's vent, the result is a composite volcano.

Further Explanation:

A volcano is an open pore in the earth's crust from which the molten rocks, gases and debris appear on the surface. The volcanoes can be categorized into four types namely composite volcanoes, cinder cones, dormant volcanoes and shield volcanoes.

Cinder cones are the volcanoes that are made up of particles and lava that escapes out of the crust from one vent. These are the simplest form of volcano. When the lava is erupted out of the earth's crust, it is blown into the air and broken into fragments that can further solid define and fall as cinders around the vent. The shape can either be and oval cone or a circular cone. Most of the cinder cones are in shape of a bowl with an average depth of about 1000 feet or less.

Composite volcanoes are those volcanoes which are very steep and symmetrical. The center vent of the volcano is filled with lava and the crest is composed of layers of lava, cinders, blocks, bombs and volcanic ash. Composite volcanoes become dormant and then the cone is destroyed.

The shield volcanoes are totally made up of the lava flows. The lava that comes out of the vent flows in all directions and a broad gently sloping come is formed.

Thus, when ash, cinders and bombs build up in a steep pile around a volcano's vent, the result is a composite volcano.

answer: after carbon dioxide enters the leaf through stomata it moves into the mesophyll cells where photosynthesis occurs and glucose is constructed. respiration occurs when glucose (sugar produced during photosynthesis) combines with oxygen to produce useable cellular energy.

explanation:

that would be called plucking : )

explanation:

''plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks". as a glacier moves down a valley, friction causes the basal ice of the glacier to melt and infiltrate joints (cracks) in the bedrock."
