What is Lava for Kids?
Direct Answer
Lava is molten rock that flows from the Earth’s interior to the surface. It’s a liquid, hot, and flowing substance that comes out of volcanoes. Imagine a big, glowing river of hot, melted rock!
What is Magma?
Before we talk about lava, let’s learn about magma. Magma is the molten rock that’s stored beneath the Earth’s surface. When magma reaches the surface, it becomes lava. So, magma is like the liquid rock that’s still underground, and lava is like the same rock that comes out of the volcano!
Types of Lava
There are different types of lava, and scientists have given them special names. Let’s learn about three main types:
• Pahoehoe: This type of lava is smooth and billowy, like a big, melted marshmallow. It forms when the lava flows slowly and has a chance to cool and solidify a little bit.
• Aa: This type of lava is chunky and rough, like a big, melted mess. It forms when the lava flows quickly and doesn’t have time to cool and solidify.
• Pillow Lava: This type of lava forms when lava flows underwater and cools quickly, forming small, pillow-like rocks.
How Lava Forms
Lava forms when magma from the Earth’s interior rises to the surface. This happens when the magma becomes less dense than the surrounding rock and starts to rise. As it rises, it heats up and melts even more, becoming lava.
What Does Lava Look Like?
Lava can look different depending on its temperature and how fast it’s flowing. It can be:
• Red: When lava is hot and flowing, it can look bright red or orange.
• Yellow: When lava cools down a bit, it can turn yellow or orange.
• Black: When lava cools down completely, it can turn black and solid rock.
Where Does Lava Come From?
Lava comes from volcanoes, which are mountains that erupt with molten rock. There are different types of volcanoes, including:
• Shield Volcanoes: These volcanoes are tall and round, like a shield.
• Stratovolcanoes: These volcanoes are tall and pointed, like a cone.
• Cinder Cones: These volcanoes are small and round, like a hill.
Interesting Facts About Lava
• Lava Can Reach Temperatures of Up to 2,000°F (1,093°C): That’s hotter than the surface of the sun!
• Lava Can Flow as Fast as 100 Feet Per Second (30 Meters Per Second): That’s like a really fast river!
• Lava Can Cool and Solidify in Just a Few Minutes: That’s faster than you can cook an egg!
Conclusion
Lava is an amazing and fascinating natural wonder. It’s a molten rock that flows from the Earth’s interior to the surface, and it comes in different types and colors. Whether it’s hot and flowing or cool and solid, lava is an important part of our planet’s geology. By learning more about lava, we can better understand the Earth and its many amazing natural wonders.
