Which part of the Earth is the source of magma?
Lava is magma that reaches the surface. Magma originates either from rising plumes of heat at hot spots in the Earth's mantle, where decompression melting takes place as the hot rock nears the surface; or, it originates in the mantle from subduction of oceanic crust, where cold, wet rock speeds melting of the subducting rock and it rises toward the surface.
Why does magma rise through the crust above it?
Magma rises through the crust due to differences in density between the magma and surrounding rock. Magma is less dense than the solid surrounding rock, so it moves upwards through cracks and fractures in the crust. As it rises, magma can also be driven by pressure differences and heat from the Earth's mantle.
Lava and magma?
Lava is molten rock that erupts onto the Earth's surface, while magma is molten rock beneath the surface. The temperature and pressure difference between them affect their behavior and appearance. Lava typically flows more fluidly, while magma can be trapped underground in magma chambers.
What language does the word igneous come from?
The word "igneous" comes from the Latin word "ignis," which means "fire." This term is used to describe rocks that form from the cooling and solidification of molten material, such as magma and lava, from within the Earth's crust.
What word means fractured surface in Earth's crust where a mass of rock is in motion?
Fault.

What are some properties of magma?
Magma has a lot of different properties. it also means lava. It is in the mantlle if it is called magma, lava is when it is on the earths crust.

What causes magma to rise to earths surface?
The magma is in the mantle, the layer under the crust. There is a convection current caused by radioactivity in the inner core which causes the plates to move. Therefore the constructive plates move apart which means magma can rise up. It'll then solidify and this is what makes volcanoes. Hence CONSTRUCTive.
What does magma intrusion means?
Magma intrusion refers to when molten rock (magma) forces its way into existing rock formations beneath the Earth's surface. This intrusion can create new igneous rock formations, as well as potentially lead to volcanic activity if the magma reaches the surface.
What is another word for magma?
Magma doesn't have an antonym, in that there is no word or expression that means its direct opposite.That being said, magma on the surface (as opposed to underground) is called lava; and once it cools, it's called lava rock or igneous rock.The other parts of the planet (i.e. not the magma) are the crust and the core. Perhaps one of these terms is what you were looking for.
What means plutons?
Plutons are large underground rock formations formed from the cooling and solidification of magma beneath the Earth's surface. They are typically composed of crystalline igneous rock and can be exposed at the surface through erosion or tectonic activity. Plutons are important in geology for understanding the history and composition of the Earth's crust.

How does the stress in Earth's crust change the surface?
it means earthquakes will happen more often
What is the origin of the word igneous?
The word "igneous" comes from the Latin word "ignis," which means fire. "Igneous" is used in geology to describe rocks that have solidified from molten material, such as magma or lava, that originated from deep within the Earth's crust.
What is crust?
Crust is the hard outer surface of something, typically the earth or a baked food such as bread or pie. In geology, the Earth's crust is the outermost layer of the Earth's surface, consisting of a variety of rocks and minerals.
