Magma that flows onto Earth's surface is called lava.
Viscous lava, such as andesitic or rhyolitic lava, flows the slowest due to its high silica content. This type of lava tends to be thicker and more resistant to flow compared to basaltic lava, which is more fluid and flows more quickly.
Lava flows are usually slow moving, giving people time to escape.
No. Lava can start fires but cannot become fire.
Magma that flows onto Earth's surface is called lava.
A lava flow is where lava flows down the side of a volcano.
the opening where the lava flows is call a vent
Magma that flows onto Earth's surface is called lava.
Ninety percent of wildfires are caused by smoking.
No. Lava flows vary in composition. Most lava flows consist of basaltic lava, which can flow as smooth phoehoe or form jagged and broken a'a. Other lava flows are more viscous and will have blocky surfaces and tend to be short and thick.
A volcano is a mountain from which lava flows out during an eruption.
Lava flows can be stopped or deflected by ridges, valleys and depressions in the ground.
When lava flows reach the sea, the lava rapidy cools to form an igneous rock.
Yes. Lava flows can be extremely destructive. Since most lava flows move slowly, though, relatively few people have been killed by them.
Yes. Stratovolcanoes can erupt blocky lava flows, basaltic lava flows, or may erupt explosively.
A long crack from which lava flows is called a fissure.
Viscous lava, such as andesitic or rhyolitic lava, flows the slowest due to its high silica content. This type of lava tends to be thicker and more resistant to flow compared to basaltic lava, which is more fluid and flows more quickly.
