Detailed explanation-1: -Flank-The side of a volcano. Lava-Molten rock that erupts from a volcano that solidifies as it cools. Crater-Mouth of a volcano-surrounds a volcanic vent. Conduit-An underground passage magma travels through.
Detailed explanation-2: -The crater is the bowl shaped opening located at the top of the volcano. The crater is also the steep sided walls made of hardened lava that surround the main vent. Lava can flow from the main vent, but not all volcanoes eject large amounts of lava.
Detailed explanation-3: -A fissure vent, also known as a volcanic fissure, eruption fissure or simply a fissure, is a linear volcanic vent through which lava erupts, usually without any explosive activity. The vent is often a few metres wide and may be many kilometres long.
Detailed explanation-4: -Shield volcanoes Lavas also commonly erupt from vents along fractures (rift zones) that develop on the flanks of the cone. Some of the largest volcanoes in the world are shield volcanoes.
Detailed explanation-5: -The slopes are the sides or flanks of a volcano that radiate from the main or central vent. Slopes vary in gradient depending on the intensity of the volcano’s eruptions and the materials that are expelled. Explosive eruptions of gas, ash and solid rock create steep slopes.
