Because if it was magma which is inside the earth will be intrusive but ash is on the earth so it is extrusive.

Is tuff igneous sedimentary or metamorphic?

Tuff is a volcanic rock that forms from the consolidation of volcanic ash and debris. It is considered a sedimentary rock because it is composed of various fragmented materials that have been deposited and lithified.


What are the 4 extrusive igneous rock structures are?

The four primary extrusive igneous rock structures are lava flows, volcanic ash deposits, tuff, and volcanic domes. Lava flows are formed from the outward movement of molten rock, while volcanic ash deposits consist of fine particles ejected during explosive eruptions. Tuff is a type of rock formed from consolidated volcanic ash, and volcanic domes are steep, mound-shaped structures created by the slow extrusion of viscous lava. These structures illustrate the diverse manifestations of volcanic activity on the Earth's surface.


What does magma that is blasted into the air form when it hardens?

When magma is blasted into the air, it cools and solidifies to form volcanic rock, such as lava bombs, volcanic ash, and tuff. The specific type of rock depends on the composition of the magma and the cooling process.


What are the names for volcanic rock?

well it could be igneous rock if you are talking about specific types (there are a lot) , but its called tephra and/or pyroclastic rock that is thrown from the volcano... the smallest of tephra is ash, then lapilli then bombs, then blocks.


Is volcanic rock only igneous?

Lava is, by preferred definition, a viscous fluid comprised of molten rock that has reached the surface. In this case, lava is not an igneous rock. However, 'lava' can also refer to the cooled and solidified product of the molten rock. In this case, lava is an igneous rock, formed from the solidification of molten lava.

What rock would most likely be found near a volcano?

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


Is tuff an igneous rock?

Yes, tuff is an igneous rock. It is formed from volcanic ash and other volcanic debris that has been compacted and cemented together.


Is the rock tuff igneous medamorphic or sedimentary?

The rock tuff is classified as an igneous rock. It forms from volcanic eruptions where ash and volcanic material are ejected into the air and then settle and compact to form tuff.


What is the difference between tough and tuff?

tough meas like strong and tuff means cool or slick

Is the following is an intrusive igneous body Pyroclast Lava Flow Lahar Batholith?

The given options are not all intrusive igneous bodies. A batholith is an intrusive igneous body formed deep within the Earth's crust, while pyroclastic flows, lava flows, and lahars are volcanic hazards associated with volcanic eruptions.


What are volcanic igneous formations?

the cycle of the rock is that firstly it is igneous rock which is formed under a volcano, the it is sedimentary rock e.g. limestone then that transforms into metamorphic rock which is marble or slate.
