Does this volcanic activity resemble a fissure eruption?
Yes, this volcanic activity does resemble a fissure eruption.
What texture refers to rocks composed mainly of mineral and volcanic fragments?
The texture that refers to rocks composed mainly of mineral and volcanic fragments is known as "clastic texture". This texture is characterized by the presence of distinct particles or fragments that are cemented together to form the rock.
What does the volcanic activity history chart reveal about the region's geological past?
The volcanic activity history chart shows that the region has experienced multiple periods of volcanic eruptions over time, indicating a history of geological activity and potential volcanic hazards in the area.
Definition for layers of ash and lava?
Layers of ash and lava refer to the various levels of volcanic material deposited during an eruption. Ash is composed of small fragments of volcanic rock, while lava is molten rock that flows out of a volcano. Together, these layers provide a record of the volcano's eruptive history and can help scientists understand past volcanic activity.
Volcanic particles about the size of a rice grains are called?
Volcanic particles about the size of rice grains are called volcanic ash. Ash is made up of small rock and mineral fragments that are expelled during a volcanic eruption.
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.
What are tephra layers?
Tephra layers are deposits of volcanic ash and fragments that accumulate as a result of volcanic eruptions. They are sorted by size and composition, creating distinct layers that can be used to date and correlate geologic events. Tephra layers are important for understanding volcanic activity and reconstructing past eruptions.
Is a cinder cone quiet or explosive?
A cinder cone volcano is typically characterized by relatively quiet volcanic activity, with eruptions consisting of gas-rich magma that produces small explosions and emits ash, cinders, and lava fragments. These eruptions are generally not as explosive or violent as those of stratovolcanoes or calderas.
What is ground hugging avalanche consisting of ashpumicerocks and volcanic gas called?
The ground-hugging avalanche consisting of ash, pumice rocks, and volcanic gas is called a "pyroclastic flow." It is a fast-moving, high-temperature mixture of volcanic ash, rock fragments, and gas that flows rapidly down the sides of a volcano during an eruption. Pyroclastic flows can be extremely dangerous and destructive.
Does Ceres have volcanic activity?
No, Ceres does not have volcanic activity.
What is the volcanic fragments that are 2-64 mm in size?
Volcanic fragments that are 2-64 mm in size are classified as lapilli. These fragments are formed during explosive volcanic eruptions when magma is fragmented into small pieces as it is ejected into the air. Lapilli can vary in composition and shape, and are larger than volcanic ash particles but smaller than volcanic blocks.
What are lava fragments that solidify almost immediately?
Lava fragments that solidify almost immediately are known as volcanic ash. Volcanic ash is composed of fine rock particles and glass fragments created during explosive volcanic eruptions. Upon cooling, these particles can consolidate to form a range of volcanic materials, including pumice and volcanic glass.
What Pyroclastic material less than 0.25mm in the diameter called?
Pyroclasts are single fragments that are produced following a volcanic eruptions where there expanding gases rapidly erupt resulting in either the fragmentation or obliteration of rock and magma. Fine-grained pyroclastic material is generally made from ash cause by extremely high fragmentation of rock or magma.
What type of rock is on Mt Snowdon?
The rock on Mount Snowdon is predominantly volcanic in origin, consisting of rhyolite and tuff formations that were formed during a period of intense volcanic activity around 450 million years ago.
What type of volcanic rock fragments or lava come out of mt fuji volcano?
Mount Fuji primarily erupts and produces basaltic to andesitic volcanic rock fragments, including tephra, pumice, and volcanic ash. The lava flows from its eruptions are typically fluid, allowing for extensive lava flow development. These materials reflect the stratovolcano's explosive and effusive eruption styles, contributing to its iconic conical shape. The volcanic activity at Mount Fuji has created a diverse range of volcanic products over its history.
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 in Antarctica does volcanic activity occur?
Volcanic activity is found in the west of Antarctica.
