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?
Io, and Venus are fed by subsurface molten rock. On Earth, the lava comes up from the mantle (which is the layer under the surface). Once there's enough molten rock — called magma — and enough pressure
But planetologists have discovered that Earth's very presence in this Goldilocks zone is itself due to an amazing stroke of luck. When the Solar System was still young, this zone came close to being taken over by the planet Jupiter.但行星学家发现，地球出现在这片“宜居带”本身就有惊人的运...
What happens to a substance when it melts? When a substance melts, it transitions from a solid state to a liquid state. 2 Is "molten" a permanent state? No, "molten" is a temporary state; the substance solidifies again as it cools. 2 Share Your Discovery Share via Social Media Embed...
What happens at a subduction zone? Tectonic plates are pieces of the Earth’s rigid outer layer that slowly move across the planet's surface over millions of years, according toNOAA. (This is the main tenet ofplate tectonics, the theory that portions of Earth's shell glide over the lower...
So, we've talked about the plates that form the earth crust and their movements and how in some places they're separating.Now, when this happens in the ocean along a mid ocean ridge, some important things can happen, in particular you can get a hydrothermal vent.This is a lot like a...
When it reaches the surface, it results in a volcanic eruption. Hence why many volcanoes are located above a magma chamber. Most known magma chambers are located close to the Earth’s surface, usually between 1 km and 10 km deep. In geological terms, this makes them part of the Earth’...
Magma is the liquefied rock within the Earth and the origin of igneous rocks. Sometimes, the magma cools below the surface to form intrusive igneous rocks when it crystallizes. If it reaches the surface, the point at which we call it lava, it cools quickly to form extrusive igneous rocks....
