- Composition. Lava on the Earth's crust is dominantly composed of silicate minerals: mostly feldspars, feldspathoids, olivine, pyroxenes, amphiboles, micas and quartz.
- Rheology. The behavior of lava flows is mostly determined by the lava's viscosity. ...
- Temperature. Lavas range in temperature from about 800 °C (1,470 °F) to 1,200 °C (2,190 °F). This is similar to the hottest temperatures achievable with a forced air charcoal forge.

What does the lava represent in the Earth?
What does the lava represent in the earth? The letter C represents a Side vent . When the magma reaches the surface of the Earth it is then called lava. The lava leaving the side vent causes the volcano to add a layer of lava and usually a layer of ash with each eruption. These eruptions build the volcano higher and wider.
What does lava do to Earth?
Other than that, lava is mostly a side-effect of volcanism, which in turn is a side-effect of the seismic activity in the Earth’s core, which is also responsible for the magnetic field that protects Earth’s atmosphere and life on Earth from cosmic radiation and solar radiation. What is the use of lava on the Earth?
What are some characteristics of lava?

How do you describe a lava rock?
The molten rock released during an eruption is referred to as lava, which rapidly cools and crystallizes to form igneous rocks. Lava rocks are a type of igneous rock known as basalt, which is composed of various mineral and chemical elements.
How do you explain lava to a child?
Lava is hot, liquefied rock that flows from a volcano or other opening in the surface of Earth. When the liquid rock is still underground it is known as magma. Igneous rock is formed when lava cools and hardens.
How would you describe lava flow?
Lava flows are streams of molten rock that pour or ooze from an erupting vent. Lava is erupted during either nonexplosive activity or explosive lava fountains.
How does lava look like?

What does lava taste like?
Hot volcano lava would instantly burn away your taste buds so the taste would not be discernible.
What is the texture of lava?
lavas tend to be rough, jagged and with either a blocky or a rubbly/clinkery surface, both formed essentially by continuous breaking and reworking of the cooled outer surface of a lava flow ( Balance and Smith 1982).
What is a sentence for lava?
1. The city was entombed in volcanic lava. 2. Lava from the volcano was flowing down the hillside.
What are some fun facts about lava?
Lava can reach temperatures as hot as 1,250℃. Lava may spurt up if there is pressure or simply flow out of the vent. The hotter and thinner the lava, the farther it will flow. When it stops flowing it hardens into rock called igneous rock.
Is lava a liquid or a solid?
lava, magma (molten rock) emerging as a liquid onto Earth's surface. The term lava is also used for the solidified rock formed by the cooling of a molten lava flow.
What happens if you touch lava?
Lava won't kill you if it briefly touches you. You would get a nasty burn, but unless you fell in and couldn't get out, you wouldn't die. With prolonged contact, the amount of lava "coverage" and the length of time it was in contact with your skin would be important factors in how severe your injuries would be!
How hot is lava?
Here are some temperatures recorded at different times and locations: The eruption temperature of Kīlauea lava is about 1,170 degrees Celsius (2,140 degrees Fahrenheit). The temperature of the lava in the tubes is about 1,250 degrees Celsius (2,200 degrees Fahrenheit).
What is a lava rock called?
When lava reaches the surface of the Earth through volcanoes or through great fissures the rocks that are formed from the lava cooling and hardening are called extrusive igneous rocks. Some of the more common types of extrusive igneous rocks are lava rocks, cinders, pumice, obsidian, and volcanic ash and dust.
What does lava rock represent?
Lava Stone Benefits Because the stones come from raw energy, they're considered to represent rebirth and shedding unneeded layers of emotional attachment. Fire's physical embodiment is the Lava Stone. It is the only rock known to be formed from nothing but fire thus, providing strength and power.
What type of rock is lava?
Extrusive Igneous RocksExtrusive Igneous Rocks: The magma, called lava when molten rock erupts on the surface, cools and solidifies almost instantly when it is exposed to the relatively cool temperature of the atmosphere.
Are lava rocks heavy?
Lightweight – lava rock is quite lightweight because of the air pockets in it.
What is Lava?
If you could dig a tunnel deep inside of the Earth, you would eventually come to an inner core that is scorching hot! This inner core contains rock that is molten, which means it is so hot that it has become a liquid. When this molten rock is inside the Earth, it is called magma.
Escaping Lava
So just how does magma escape from inside the Earth and become lava? This molten rock emerges through an opening in the Earth called a volcano. Volcanoes occur when pieces of the Earth, called plates, move and either come together or drift apart.
Lava Flows
So how does lava flow? The answer depends on something called viscosity. Viscosity is a word used to describe how thick or thin the lava is. Thicker lava has a higher viscosity and will flow more slowly. This lava creeps along the Earth's surface and is not very dangerous to humans.
