What else can I help you with?
Do volcanoes need lava to be known as actual volcanoes?
No, volcanoes do not need lava to be volcanoes.
Can lava make volcanoes?
NO, volcanoes make lava.
What is a molten rock from the earth's interior that erupts from volcanoes?
This is known as lava.
What are oozing volcanoes?
Oozing volcanoes are volcanoes that primarily release slow-moving lava rather than explosive eruptions. The lava typically flows out of the volcano's vent and can travel long distances, posing a threat to surrounding areas. Oozing volcanoes are also known as effusive volcanoes.
What are constructive volcanoes?
Constructive volcanoes, also known as shield volcanoes, are characterized by their broad, gently sloping sides and low viscosity lava flows. These volcanoes are typically formed from multiple eruptions of basaltic lava, which spreads out in thin layers to create a gradual and shield-like shape. Constructive volcanoes are associated with effusive eruptions, where lava flows steadily and continuously.
What is molten before it erupts?
It is molten magma that erupts from volcanoes - commonly known as lava.
The magma released from volcanoes is?
lava
What do quiet eruptions do?
Quiet volcanoes explode with much less suddenness, because lava does not cool and harden. The lava that creates a quiet volcano is still runny and flowing, and do not plug the craters and trap huge quantities of explosive gas. However, pockets of hot gas form that squirt fountains of lava into the air. Because lava flows away before hardening, broad sheets of lava and wide, gently sloping domes are formed around the volcano. When the lava has dried, it forms a rock known as basalt.
When can you say a volcano is in a quiet eruption?
Quiet volcanoes explode with much less suddenness, because lava does not cool and harden.

Do some volcanoes actually ooze?
Yes, some volcanoes can indeed ooze lava, especially those with low viscosity magma which flows more smoothly. This type of lava often results in slow, continuous flows rather than explosive eruptions. Volcanoes like Hawaii's Kilauea are known for this type of oozing lava activity.
What forms from lava that is higher in water and silica content than lava that forms shield volcanoes?
Lava that is higher in water and silica content tends to be more viscous and can lead to explosive eruptions. This type of lava forms stratovolcanoes, also known as composite volcanoes, which are characterized by steep slopes and alternating layers of lava flows, ash, and volcanic rocks. Examples include Mount St. Helens and Mount Fuji.
How do volcanoes shape the Pacific Northwest?
volcanoes will erupt and let out lava then the lava will harden and that will be new land.
