Why is lava and magma not a rock?
Lava and magma are not rocks because they are liquids and cant harden because they are to hot to harden and cant cool themselves down long enough to form a hard structure. Magma and lava is rock - it's just been superheated by the Earth's core.
Layers of thin runny lava that flow over a wide area before they cool and harden can build up what?
Layers of thin runny lava that flow over a wide area before they cool and harden can build up lava plateaus or volcanic fields.
What happens to magma and lava once they cool and harden?
Once magma and lava cool and harden, they solidify to form igneous rocks. The texture and composition of the rocks depend on the cooling rate and mineral content. Over time, these rocks can be uplifted, eroded, and transformed in the Earth's crust through various geological processes.
How long does the lava stay hot for?
It usually depends on how hot the lava and how cold the water is. I think it can take around half a minute for the lava to cool off when its in cold water and that's all i can think of.
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.
What rock is formed when magma and lava cool and harden?
Igneous Rock.
Where does lava harden?
It hardens when it starts to cool off at the bottom of the mountain/volcano.

What makes a new crust layer?
Volcanic activity in which lava and magma cool and harden into rock and stone.
How do volcanoes impact the earth's surface?
They can form islands: when hot lava reaches the ocean, it will harden and form an island.
How do you heat treat or harden a metal chisel?
Heat the metal red hot. To harden the metal, cool it quickly by dunking it into cold water. To get a soft metal, let it cool slowly.
Layers of thin runny lava that flows over a wide area before they cool and harden can build up a?
Pahoehoe and aa
What are melted rocks that cool and harden called?
Molten rock is magma. It is called lava once it has cooled and hardened.
Does the lava harden?
Actually, it does not. It is soft.

When you have volcanoes on Mercury would the lava get hotter?
No. While the day side of Mercury is quite hot, it is not nearly as hot as lava. So any lava that would erupt on Mercury would still cool down and solidify. The lack of an atmosphere would mean that the lava would cool more slowly than lava on Earth does.
