1. What is a Volcano? - Definition & Eruptions
Volcanoes are vents that allow lava, rock fragments and gases to escape from layers beneath the earth's surface. Learn how volcanoes form both on land and underwater and why they erupt.
2. Volcanic Landforms: Types & Formation
Volcanic eruptions pull materials up from deep within the earth to form various volcanic landforms, such as lava domes, lava plateaus, fissure eruptions, craters and calderas. Learn about these volcanic landforms and how they are created.
3. Types of Volcanoes: Shield, Cinder Cones & Composite Cones
The earth ejects lava, rock fragments, hot vapor and gases during volcanic eruptions. Volcanoes vary based on size, shape, composition and eruptive style. Learn about the different types of volcanoes, such as shield, cinder cone and composite cone.
4. Volcanic Eruption: Gases Released & Their Effects
Volcanic eruptions emit water vapor and toxic gases into the atmosphere. Learn about the gases emitted from an erupting volcano, such as carbon dioxide, sulfur dioxide, hydrogen sulfide, hydrochloric acid and carbon monoxide and their effects in this video lesson.
5. Lava Flow, Pyroclastic Flow, Pyroclastic Surge & Tephra: Preventing Volcanic Hazards
Volcanic hazards are any type of volcanic process that leads to destruction or threatens life. Learn about specific volcanic hazards including lava flows, pyroclastic flows, pyroclastic surges and tephra and measures used to prevent or reduce damage
6. Volcanic vs Plutonic Igneous Rocks: Definition and Differences
Volcanic and plutonic rocks are types of igneous rock. Volcanic rocks form when lava cools and solidifies on Earth, and plutonic rocks form when magma cools and solidifies below Earth. Learn about different characteristics of these igneous rocks.
