Medium-sized tephra consists of pyroclastic material that falls between fine ash and coarse lapilli in size. It typically ranges from 2 to 64 millimeters in diameter and is produced during explosive volcanic eruptions. Medium-sized tephra can pose hazards to aviation, infrastructure, and human health depending on the volcanic activity.
Blocks is the name used for the biggest pieces of tephra. Tephra is produced by a volcanic eruption.
Large round tephra are called bombs, while streamlined tephra are known as lapilli.
No, tephra is not always silicic. Tephra can be composed of a variety of materials, including silicic, basaltic, andesitic, or rhyolitic compositions, depending on the volcanic eruption that produced it.
Yes, shield volcanoes can sometimes produce tephra during explosive eruptions. However, these eruptions are less common compared to the effusive lava flows that are typically associated with shield volcanoes. Tephra produced by shield volcanoes tends to be finer-grained compared to the tephra from stratovolcanoes.
Tephra is dangerous because it can cause respiratory issues when inhaled, and damage to infrastructure and crops when deposited. The size, speed, and distance tephra fragments travel during volcanic eruptions can also pose a risk to people and property in the surrounding areas.

Blocks is the name used for the biggest pieces of tephra. Tephra is produced by a volcanic eruption.
A tephra cone volcano, also known as a cinder cone volcano, is made entirely of tephra. Tephra is a term for fragmented material produced by a volcanic eruption, such as ash, cinders, and bombs. Tephra cone volcanoes are typically small in size and have steep slopes due to the build-up of tephra fragments from explosive eruptions.
Large round tephra are called bombs, while streamlined tephra are known as lapilli.
Tephra is basically ash, rock, cinders, and solidified lava spurted from a volcano.
No, tephra is not always silicic. Tephra can be composed of a variety of materials, including silicic, basaltic, andesitic, or rhyolitic compositions, depending on the volcanic eruption that produced it.

Yes, shield volcanoes can sometimes produce tephra during explosive eruptions. However, these eruptions are less common compared to the effusive lava flows that are typically associated with shield volcanoes. Tephra produced by shield volcanoes tends to be finer-grained compared to the tephra from stratovolcanoes.
If you are referring to the crossword puzzle clue, a medium sized tephra is also known as lapilli.
Tephra is dangerous because it can cause respiratory issues when inhaled, and damage to infrastructure and crops when deposited. The size, speed, and distance tephra fragments travel during volcanic eruptions can also pose a risk to people and property in the surrounding areas.
A combination volcano develops from repeated lava eruptions and the accompanying tephra deposits Tephra is the debris from the eruption..
