Is Kohala volcano extinct?
Kohala completed its shield-building stage 245,000 years ago and has been in decline ever since. Potassium-argon dating indicates that the volcano last erupted about 120,000 years ago in the late Pleistocene. The United States Geological Survey has assessed the extinct Kohala as a low-risk area.

What is Volcano explain with diagram?
A volcano is an opening in the surface of the Earth from which hot magma flows out. The following are the structural features of a volcano: Vent: It is an opening from which hot magma flow out to the surface of the Earth. It is a circular pipe like structure.
Why is Kilauea so active?
Kilauea volcano Activity at Kilauea is driven by the buoyant upwelling of a plume of hot mantle, which provides the heat to generate magma beneath the volcano. This magma has the potential to erupt from several different locations, or vents, on the volcano.
How lava is formed?
Lava forms when magma erupts from a volcano. As pressure is released gases, dissolved in the magma, bubble out so the composition of lava changes. Most lava flows are formed by the eruption of hot (around 1200oC) basalt magma, (see video clip above).
What are the three main types of volcano?
Composite, shield, cinder cones, and supervolcanoes are the main types of volcanoes. Composite volcanoes are tall, steep cones that produce explosive eruptions.

What causes a volcano?
A volcano is formed when hot molten rock, ash and gases escape from an opening in the Earth’s surface. The molten rock and ash solidify as they cool, forming the distinctive volcano shape shown here. As a volcano erupts, it spills lava that flows downslope. Hot ash and gases are thrown into the air.
What is the coolest volcano?

- Mount Kelimutu, Indonesia.
- Kilauea and Mauna Kea, Hawaii.
- Mount Fuji, Japan.
How do you introduce a volcano?
Volcanoes erupt when magma, red-hot liquid rock, seeps up through a vent in the earth. More violent eruptions occur when pyroclastic material – a mixture of magma, rocks, ash, and hot gases – is exploded upward by pressure caused by underground gases and magma.
Is Kilauea still active 2020?
Kilauea volcano (Hawai’i): effusive eruption continues The effusive eruption of the volcano continues and has remained essentially unchanged. The western fissure continues to supply the lava into the growing Halema’uma’u lava lake.

What is a volcano for kids?
A volcano is a landform (usually a mountain) where molten rock erupts through the surface of the planet. In simple terms a volcano is a mountain that opens downward to a pool of molten rock (magma) below the surface of the earth. It is a hole in the Earth from which molten rock and gas erupt.
