What else can I help you with?
Why is the atmosphere affected after a volcanic eruption?
likely due to the gases and ash that are ejected during the eruption
What is an eruption cloud?
An eruption cloud is a large plume of volcanic ash, gases, and other material that is ejected into the atmosphere during a volcanic eruption. These clouds can reach high into the atmosphere and pose hazards to aviation, health, and the environment.
What type of volcano is build almost entirely from ejected lava fragments?
The type of volcano that is built entirely of ejected lava fragments is a volcanic cone. Volcanic cones can be of varying types, and it depends upon the nature, and size of the fragments ejected during the eruption.
Where does the ash of a volcano come from?
Volcanic ash forms when magma is explosively ejected from a volcano. The explosive force of expanding gasses in the magma blasts it apart into small particles, which then solidify to form tiny shards of glass.
Large angular volcanic fragments are called?
Volcanic fragments are small pieces of rock that come from a volcano. Fragments are usually thrown in the air during a volcanic eruption.
Why is the atmosphere affected after a volcanic eruption?

Is during an volcanic eruption particles called lava ranging from very fine dust to pieces weighing several tons are ejected?
They are called fragments, fragments.
What are pyroclastics?
Pyroclasts are rock fragments or rocks formed from volcanic fragments thrown into the air as a result of a volcanic eruption. Also known as tephra, some examples of these rocks include pumice, reticulite and scoria.

What does tephara mean?
"Tephra" refers to fragments of volcanic rock, ash, and other material ejected during a volcanic eruption. These fragments can vary in size from ash particles to large blocks. The term is often used in volcanology to describe the material that is produced during explosive volcanic activity.
Large angular volcanic fragments are called?
Volcanic fragments are small pieces of rock that come from a volcano. Fragments are usually thrown in the air during a volcanic eruption.
Where does the ash of a volcano come from?
Volcanic ash forms when magma is explosively ejected from a volcano. The explosive force of expanding gasses in the magma blasts it apart into small particles, which then solidify to form tiny shards of glass.
Magma that is rejected during a volcanic eruption forms igneous rocks?
Magma that is ejected during a volcanic eruption forms extrusive igneous rocks. They are also referred to as volcanic rocks.
What is tephra?
Tephra is produced naturally by volcanic eruptions and refers to the material produced when the volcano erupts. Tephra comes in a range of forms and are classified by size Ash, Lapilli or Volcanic blocks.
During a volcanic eruption, particles calledfine dust to pieces weighing several tons, are ejected?
Pyroclastic material. The fragments ejected during eruptions range in size from very fine dust and ash to pieces that weigh several tons.
Cinder are the largest fragments that erupt from volcano true or false?
False. The largest fragments that erupt from a volcano are called volcanic bombs, not cinders. Volcanic bombs are typically larger than 64 mm in diameter and are formed when semi-molten lava is ejected during an explosive volcanic eruption.
