A cytoplasm is a gel like liquid material that is present within a cell. It is enclosed by a cell membrane. All the organelles such as nucleus, endoplasmic reticulum, mitochondria in a typical eukaryotic cell are embedded inside this liquid material. Cytoplasm consists of molecules for example enzymes which are responsible for breaking down of cellular wastes. It is primarily made up of water and salts. It is responsible for giving the cell it's shape and keeping the organelles in their positions.
Pyroclastic flows,lava flows and lahars are hazardous. Geothermal energy is beneficial. Volcanic ash and volcanic materials can be both hazardous and beneficial. Hope this helps you!
