How do you explain a volcanic eruption to a child?
As a volcano erupts, it spills lava that flows downslope. Hot ash and gases are thrown into the air. Some volcanoes are covered with snow and ice. If they erupt, melted snow and ice mixes with mud and volcanic ash and flows down mountain.
How are volcanoes formed Year 3?
Volcanoes are formed when magma at the centre of the Earth pushes its way upwards through the Earth through a long shaft. When the magma travels through the Earth’s crust it emerges as lava. Once this lava has erupted onto the Earth’s surface, it cools and hardens into a pile of rock.
Why do volcanoes erupt lesson for kids?
Volcanic eruptions happen when gas bubbles inside magma, or hot liquid rock, expand and cause pressure to build up. Smaller eruptions cause lava, or magma that has left the earth’s crust, to flow out of the volcano, while larger eruptions can cause violent explosions that send rocks, ash, and gas into the air.
How do you make a volcano for preschoolers?
Here’s how you can do it.
- Step 1: First, place an empty plastic bottle in a mound of sand.
- Step 2: Use a funnel to add some baking soda to the bottle.
- Step 3: Mix some food coloring and vinegar together and pour this mixture inside the bottle and watch your volcano erupt!
What are volcanoes definition for kids?
A volcano is a mountain or hill with an opening. When a volcano erupts, magma is pushed up through the opening with great force. When magma reaches the Earth’s surface, it is called lava. Lava can be as hot as 2,200°F (1,204°C). Some volcanic eruptions are explosive.
What is a volcano short answer?
A volcano is an opening in the earth’s crust through which lava, volcanic ash, and gases escape. Beneath a volcano, liquid magma containing dissolved gases rises through cracks in the Earth’s crust. As the magma rises, pressure decreases, allowing the gases to form bubbles.
What are volcanoes Year 3?
What are volcanoes? A volcano is an opening in the Earth’s crust that allows magma, hot ash and gases to escape. Volcanoes can look like mountains or small hills, depending on what type they are. Magma is molten rock – rock that is so hot it has turned into liquid.
Why do volcanoes erupt for kids?
The rock inside the planet we live on can melt to form molten rock called magma. This magma is lighter than the rocks around it and so it rises upwards. Where the magma eventually reaches the surface we get an eruption and volcanoes form.
