2010年6月10日 · Lava, the melted rock that shoots out of volcanoes, can flow at temperatures of thousands of degrees Fahrenheit. Lava that's on the cooler side comes out of volcanoes at only pizza oven-like...

2025年3月22日 · 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. Lava, which is exceedingly hot (about 700 to 1,200 degrees C [1,300 to 2,200 degrees F]), can be very fluid, or it can be extremely stiff, scarcely flowing.

Lava is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a moon onto its surface. Lava may be erupted at a volcano or through a fracture in the crust, on land or underwater, usually at temperatures from 800 to 1,200 °C (1,470 to 2,190 °F).

2010年5月6日 · Lava is hot for two primary reasons: Pressure and radiogenic heating make it very hot deep in the Earth (about 100 km down) where rocks melt to make magma. The rock around the magma is a good insulator so the magma doesn't lose much heat on the way to the surface.

2023年6月12日 · Lava is the form of magma, or molten or semi-molten rock, that erupts to the surface, such as via a volcano or through a crust fracture. We all know lava is pretty hot, but exactly how hot...

How HOT is Hot Lava? The temperature of erupting lava from Kīlauea is about 2,100 degrees Fahrenheit (1,150 degrees Celsius). Erupting lava cools quickly when it is exposed to air, hundreds of degrees per second, though rocks may steam for years after an eruption.

Not all lava possesses the same heat level. Generally speaking, the more viscous the liquid rocks, the cooler it is. The temperature difference can be around 200 degrees Celsius. Although the liquid is viscous and thick, it can be quite fast. Other facts about lava state that some of them can move up to 10 kph even through thick greenery.

When lava first breaks through Earth's surface, it is an extremely hot liquid. On average, fresh lava can be between 1,300° F and 2,200° F (700° and 1,200° C)! Depending on its exact temperature, fresh lava usually glows either orange/red (cooler) or white (hotter). Eventually, lava cools and returns to solid rock again.

2023年1月5日 · Lava is an incredibly hot substance that forms when magma from the Earth’s depths rises to the surface and erupts through a volcano. It’s so hot that it can melt and fuse solid rock, creating...

2025年1月13日 · The temperature of lava can range from about 1,300 to 2,200 degrees Fahrenheit (700 to 1,200 degrees Celsius), making it one of the hottest substances on Earth’s surface. This extreme heat comes from magma, the molten rock that originates deep within the Earth and rises during volcanic activity .
