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.
How does hot lava cool and harden?
Lava cools as anything else does; it loses heat to cooler surroundings. As it cools its atoms and ions slow down and are eventually locked in place by bonds with neighboring atoms an ions. The lava is essentially freezing.
Why do most volcano have a mountain of hardened rock and ash around them?
When a volcano erupts, the lava that shoots up in the air(some times it just rolls down) it just doesn't stay in the air. Gravity pulls it down to Earth and the lava falls everywhere. Over a period of time, the lava hardens making mountains of igneous rock. Thank you, Gravity.
Do cinder cones produce lava flows?
Yes. Although its typical eruptions produce simple lava flows, there have been cases where water came in contact with magma, triggering explosive eruptions with pyroclastic flows.
What does magma that is blasted into the air form when it hardens?
When magma is blasted into the air, it cools and solidifies to form volcanic rock, such as lava bombs, volcanic ash, and tuff. The specific type of rock depends on the composition of the magma and the cooling process.

Large blobs of magma that hardens in the air?
Firstly, it forms lava (liquid). When it hadens, it becomes a rock (solid).
What eruption does Mt St Helen's have?
The eruption that Mt St Helen has is an exploding volcano that shoots lava and rocks into the air.

What is a lightly formed extrusive rock formed when lava cools so fast it traps pockets of air inside?
pumice
Lava rock with air pockets?
Lava rock with air pockets are known as vesicular lava rock. These air pockets are formed during the solidification process of lava, which traps gas bubbles within the rock. This gives the rock a porous and lightweight texture.

How do temperature pressure and fluid content affect the formation of magma?
The air affects magma. Once magma is released above ground, called lava, the air hardens it. While it is underground, the higher the temperature and pressure, the runnier the magma.
How is lava rock formed and what is the process behind its creation?
Lava rock is formed when molten lava from a volcano cools and solidifies on the Earth's surface. This process involves the lava cooling rapidly, either in the air or in water, which causes it to harden into a rock-like structure. Over time, the lava rock can weather and erode, eventually breaking down into smaller pieces.
Does lava cool down in the air?
No. Lava heats up the air. In turn, the air cools the lava.
Do cinder cones produce lava flows?
Yes. Although its typical eruptions produce simple lava flows, there have been cases where water came in contact with magma, triggering explosive eruptions with pyroclastic flows.
A light frothly extrusive rock formed when lava cools so fast that it traps pockets or air inside?
Pumice
