• What is volcano?
• The Earth's crust consists of several large plates that are constantly moving.
• A volcano is an opening on the earth’s surface where molten rock (magma) can escape from below the earth’s surface.
• Volcanic eruptions occur when magma rises to the surface through fissures or vents, often accompanied by explosive activity such as ash clouds and lava flows.
• Plate tectonics is the theory that explains how these plates move, interact with one another, and create geological features on our planet.
• Volcanic eruptions occur when magma rises to the surface through fissures or vents in the earth’s crust.
• Shield Volcanoes - These volcanoes have gentle slopes and are formed by repeated lava flows over long periods of time.
• Cinder Cone Volcano - A small cone-shaped volcano composed mainly of cinders and ash ejected during eruption.
• There are three main types of volcanoes: shield volcanoes, composite volcanoes, and cinder cone volcanoes.
• Shield Volcano - A type of volcano characterized by gentle slopes and broad bases, formed primarily by fluid basaltic lava flows.
• A volcano is an opening in the Earth’s crust where lava, ash, rock fragments, hot gases, and steam can escape from below the surface.
• Volcanic eruptions occur when magma rises to the surface through fissures or vents, which may be located along plate boundaries.
• There are three main types of volcanoes based on their shape:
