What else can I help you with?
Very fluid balsaltic lava may erupt out of fissures in the surface When the lava hardens it may form a feature called a?
Lava plateau
What rocks come from lava flow?
Lava flows cool to form extrusive igneous rock. Most lava flows consist of basaltic lava, cooling to form a dark rock called basalt. Some, however, may consist of andesite or, rarely, rhyolite and similar lavas.
What are the three status of a volcano and what do they mean?
The Volcano has a huge structure below it. The molten rock deep within it is called Magma. A subsidiary volcano may form from the main body, this is called a Parasitic cone. Some times some volcanic materials may seep out near the volcano, this opening is called Vent. The molten rock erupting from the Volcano is called Lava. The mouth of the volcano is called Crater. The highest point of a volcanic mountain is called Summit while the underground passage of magma is called Conduit. The Channel through which lava is ejected out is called the Throat. Ash or fragments of rocks and lava are what is blasted out forming Ash clouds due to the explosion
The hole in the top of a volcano?
The hole in the top of a volcano is known as the crater. It is the opening through which volcanic gases, ash, and lava are expelled during an eruption. Craters can vary in size and shape depending on the type of volcano.
Which features may occur when volcano lava cools at the surface?
Lava that cools at the surface can form features such as lava flows, which are large sheets of solidified lava. It can also create lava tubes, which are tunnels formed when the outer layer of the lava flow cools and hardens while the inner lava remains molten and continues to flow. Additionally, lava may form spatter cones or lava fountains when ejected into the air and solidifies before hitting the ground.
What mountain would lava may form?
Lava may form a mountain called a volcano!
Very fluid balsaltic lava may erupt out of fissures in the surface When the lava hardens it may form a feature called a?
Lava plateau
When a volcano erupts lava may flow onto the surface. What type of rock does the lava cooling form?
When lava cools on the surface, it forms igneous rock called basalt.

Why do holes form in extrusive rocks?
the holes in extrusive igneous rocks (lava) are called vesicles. They are formed by gas escaping from the rock when molten, leaving bubbles in the melt which which may be preserved when the lava solidifies
Does lava have gas?
Yes. Gases may be trapped in lava. These may form bubbles on the surfaces of a flow, giving it a vesicular texture when it cools.
How can a cone shaped mountain form?
A cone shaped mountain may be kind of volcano called a stratovolcano, which is built from ash deposits and very viscous lava flows. Some stratovolcanoes have very well formed cones, including Mount Fuji in Japan, and Mount St Helens prior to its cataclysmic eruption in 1980.

What features may occur when volcano lava cools at the surface?
When volcano lava cools at the surface, it may form different features such as lava rock formations like basalt columns, lava tubes, and aa or pahoehoe lava flows. These features depend on the cooling rate and composition of the lava.
How do volcanos affect the Earth's surface?
Volcanoes can change the surface of the earth in several ways. The lava that is ejected for the volcano may dry and form a new layer of sediment on the ground. The chambers of magma underground can become too pressurized and make a whole new volcanic mountain. Hope that answers your question!
