When magma or lava cools the result is quizlet?
Magma is molten rock below Earth's surface, and lava is molten rock that has erupted onto Earth's surface. What happens when lava cools and crystallizes? It becomes igneous rock. You just studied 33 terms!
When magma cools what type of rock does it become?
igneous rock Extrusive, or volcanic, igneous rock is produced when magma exits and cools above (or very near) the Earth's surface. These are the rocks that form at erupting volcanoes and oozing fissures.
What is formed when molten magma cools down?
Igneous rocks form when magma (molten rock) cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust. All magma develops underground, in the lower crust or upper mantle, because of the intense heat there.
What is the type of rock formed from lava that cools quickly?
Extrusive igneous rocks form when lava reaches the Earth's surface a volcano and cools quickly. Most extrusive (volcanic) rocks have small crystals. Examples include basalt, rhyolite, andesite, and obsidian.
What is the type of rock formed when magma or lava cools quizlet?
Igneous rocks are formed from magma or lava that cools and hardens.
When magma cools what type of rock will form quizlet?
Terms in this set (31) How are Igneous rocks formed? When magma cools it becomes a solid and it forms an igneous rock.
What happens when lava cools?
When the lava cools down, it forms solid rock. The lava that flows from Hawaiian volcanoes is very runny. It flows a long way before it cools. Gradually the new rock builds up a cone.
What happens when lava cools quickly?
Magma that cools quickly forms one kind of igneous rock, and magma that cools slowly forms another kind. When magma rises from deep within the earth and explodes out of a volcano, it is called lava, and it cools quickly on the surface. Rock formed in this way is called extrusive igneous rock.
What happens when magma cools rapidly in mineral formation quizlet?
Rapidly cooling magma/lava results of large number of tiny crystals and rocks with small, interconnected mineral grains. Rocks tht are made of weathered bits of rocks and minerals. Forms when dissolved minerals precipitate from water solutions. Heat, pressure, and hydrothermal solutions.
What two types of igneous rock are formed as each cools?
What two types of igneous rock are formed as each cools? Lava is magma that flows out onto Earth's surface. Magma is molten rock below Earth's surface. –extrusive igneous rocks are formed when lava cools, and intrusive igneous rocks are formed when magma cools.
What type of rock is cool?
Igneous – Igneous rocks are created when magma or lava cool. They can be intrusive, which means that the magma cools in the Earth's crust, or extrusive, which means that lava cooled on the surface of the Earth or on the seafloor.
What happens when magma cools slowly in mineral formation quizlet?
If magma cools very slowly, few centers of crystal growth develop. Slow cooling also allows charged atoms, or ions, to move large distances within the magma. Slow cooling results in the formation of large crystals.
What is lava called when it cools?
Lava rock, also known as igneous rock, is formed when volcanic lava or magma cools and solidifies. It is one of the three main rock types found on Earth, along with metamorphic and sedimentary.
What happens after lava cools and new landforms?
Lava Plateaus The lava flows over a large area and cools. This creates a large, flat surface of igneousrock. Lava plateaus may be huge. The Columbia Plateau covers over 161,000 square kilometers (63,000 square miles).
What is cooled magma called?
Any rock that forms from the cooling of magma is an igneous rock. Magma that cools quickly forms one kind of igneous rock, and magma that cools slowly forms another kind. When magma rises from deep within the earth and explodes out of a volcano, it is called lava, and it cools quickly on the surface.
What is lava called when cold?
Lava rock, also known as igneous rock, is formed when volcanic lava or magma cools and solidifies. It is one of the three main rock types found on Earth, along with metamorphic and sedimentary.
What happens when magma cools rapidly in mineral formation?
If the magma cools rapidly then the reactions are much quicker and the mineral crystals (grains) are smaller. Igneous rocks will have a distinctive appearance (this is referred to as texture) based on the rate of cooling (fast or slow).
Does volcanic glass form when lava cools slowly?
Very quickly cooled lavas, typically those quenched in water, will have a glassy texture. They cool too quickly to form crystals. Glasses do not have an orderly arrangement of atoms and there are therefore no minerals, in the strict sense, in them. Volcanic glass is called obsidian.
What does lava become when it cools?
As magma cools the elements within the magma combine and crystalize into minerals that form an igneous rock. Magma cools either below the surface or at the surface (magma that reaches the surface is called lava). As magma cools igneous rock is formed.
What happens to cool lava?

What happens when rock cools?
Similarly, liquid magma also turns into a solid — a rock — when it is cooled. Any rock that forms from the cooling of magma is an igneous rock. Magma that cools quickly forms one kind of igneous rock, and magma that cools slowly forms another kind.
What happens to lava when it cools?
When the lava cools down, it forms solid rock. The lava that flows from Hawaiian volcanoes is very runny. It flows a long way before it cools.
Does magma and lava form sedimentary rocks?
Igneous rocks form when molten rock (magma or lava) cools and solidifies. Sedimentary rocks originate when particles settle out of water or air, or by precipitation of minerals from water.
What cools down lava?
Water has been found to be the most practical means to achieve lava cooling. Water absorbs heat from the lava; even more so, if it heats up to the boiling point and changes to steam.
What happens after magma is formed?
Magma cools and crystallizes to form igneous rock. Igneous rock undergoes weathering (or breakdown) to form sediment. The sediment is transported and deposited somewhere (such as at the beach or in a delta, or in the deep sea). The deposited sediment undergoes lithification (the processes that turn it into a rock).
What igneous rock is formed from lava?
When lava reaches the surface of the Earth through volcanoes or through great fissures the rocks that are formed from the lava cooling and hardening are called extrusive igneous rocks. Some of the more common types of extrusive igneous rocks are lava rocks, cinders, pumice, obsidian, and volcanic ash and dust.
What happens when lava cools too quickly?
Lava that cools slowly forms crystals, but lava that cools very quickly forms glass. Because the air temperature (around 25°C) is so much cooler than the lava temperature (1000°C+), the lava at the surface cools very quickly into glass.
What is magma and lava?
Scientists use the term magma for molten rock that is underground and lava for molten rock that breaks through the Earth's surface.
What is magma Short answer?
Magma is extremely hot liquid and semi-liquid rock located under Earth's surface. Earth has a layered structure that consists of the inner core, outer core, mantle, and crust. Much of the planet's mantle consists of magma. This magma can push through holes or cracks in the crust, causing a volcanic eruption.
How lava is formed?
Lava forms when magma erupts from a volcano. As pressure is released gases, dissolved in the magma, bubble out so the composition of lava changes. Most lava flows are formed by the eruption of hot (around 1200oC) basalt magma, (see video clip above).
