What happens after magma is formed? Which igneous rock forms when basaltic lava hardens? What forms when a large volcano collapses in on itself? What are the two types of magma? In what ways can magma be generated from solid rock?
such a simple,ordinary job,he replied,“What happens if someone wants to know where the restrooms are,when the parade starts or what bus to take back to the campgrounds?We need to know the answers or where to get them quickly. Our constant aim is to help our guests enjoy the party.”...
Batholiths are the largest species of magma intrusion. They can reach hundreds of kilometres across, and are classified as having at least 100km² of top exposure. They are formed as a consequence of a vast amount of magma that is built up by a series of smaller intrusions occurring in...
After the initial explosions, groundwater from surrounding lands begins draining towards the crater and fuels additional blasts. These continue until the supply of local groundwater is depleted or the magma source has been depleted or cooled. The 1977 eruption at the East Ukinrek Maar Crater, ...
Without the intervention of Saturn, Jupiter would have ended up in the zone where Earth now is. Earth would never have formed, and we would not be here.如果没有土星的介入，木星可能最后会在现在地球所在的区域。那么地球就不会形成，我们也不会在这里了。Our planet was luckier than its future ...
Although experts believe “the probability of a volcanic eruption is relatively low,” the relentless inflation and recent shaking of Italy's Campi Flegrei caldera raise questions for experts—and locals.
That tale is Earth’s history — how the planet went from a rock covered in magma (岩浆) oceans to a green and blue orb (球体) filled with life. Between those inhospitable beginnings and now, continents formed and were tom apart, mountain ranges appeared and disappeared, ice caps spread ...
This type of natural disaster happens when underground stresses cause two sections of the earth to abruptly move past one another. The sudden motion releases energy. A small earthquake can hardly be felt, but a large earthquake releases so much energy that buildings can tumble as entire cities ...
What happens after a volcanic eruption? What type of volcano is Mount Tambora? Why did the Eyjafjallaj?kull volcano erupt? How was Yellowstone formed geologically? What causes hot spot volcanoes? How does a fissure volcano erupt? What effects does a volcano have on the environment? The Galera...
although the crash did not destroy Earth. The debris kicked up from the collision eventually coalesced to create the Moon. That explains why the Moon and Earth are closely related in their composition. However, it's also possible that after the collision, a synestia formed and our planet and...
