Molten rock under ground?
Magma or lava. Classified as mafic or felsic, depending on it's minerology.
What is formed when the tectonic plated disvergent?
When tectonic plates diverge, magma is allowed to well up to the Earth's surface and harden, forming new land.
How do temperature pressure and fluid content affect the formation of magma?
The air affects magma. Once magma is released above ground, called lava, the air hardens it. While it is underground, the higher the temperature and pressure, the runnier the magma.
What comes out first magma or lava?
magma is lava that has not been exposed to the air before eruption.
What happens when rising magma breaks through the earth's crust?
When magma comes in contact with water first the water will stem because the magma is so hot the water is at or past its boiling point them the magma will harden fast because instead of its slow cooling prossess it is spead up from the waters temperature it is a big mess :) luvhh jasmine chanda
What are four types pyroclastic material?
Volcanic bombs, large blobs of magma that harden in the air, lapilli, pebblelike bits of magma that harden before they hit the ground, volcanic ash, forms when the gases in stiff magma expands, and volcanic blocks, large angular pieces of solid rock.
What happens to magma and lava when they coll and harden?
it turs to rock
Identify four types of pyroclastic material and the characteristics of each type of material?
Volcanic bombs, large blobs of magma that harden in the air, lapilli, pebblelike bits of magma that harden before they hit the ground, volcanic ash, forms when the gases in stiff magma expands, and volcanic blocks, large angular pieces of solid rock.
Volcanism that allows magma to seep into the crustal layers and harden?
internal
What rock is formed when magma and lava cool and harden?
Igneous Rock.
Can magma cool and harden into a sedimentary rock?
yes with the minerals and time
Why is lava and magma not a rock?
Lava and magma are not rocks because they are liquids and cant harden because they are to hot to harden and cant cool themselves down long enough to form a hard structure. Magma and lava is rock - it's just been superheated by the Earth's core.
What does magma harden into once it reaches earth's surface?
It hardens because it cools.
Which type of rock Froms after magma or lava cools and harden?
Igneous rocks.
Magma that forces across rock layers harden into?
its acutally a dike trust me
What happens to magma and lava once they cool and harden?
It becomes igneous rocks>
What is formed when a magma chamber cools slowly and hardens underground?
rock because when the lava or magma cools slowly it starts to harden.
