What type of volcano forms tuff pumice and pea sized pieces of basalt?
Cinder cone volcano forms tuff, pumice, and pea-sized pieces of basalt through explosive eruptions of gas-rich magma. These types of volcanoes have steep slopes and are typically composed of loose volcanic materials.
Is volcanic ash pebble-sized particles?
No. Pebble-sized particles from a volcano are called lapilli. Ash is sand-sized or smaller.
A geologist collects five different rock samples The geologist identifies the five samples as pumice granite basalt siltstone and sandstone If you were a geologist how would you divide the samp?
You would divide them into how the rocks were formed.Pumice, granite and basalt are all made from molten material that has since cooled. These rocks are calledigneous rocksthe other two are made up ofbits and piecesof other rock that have been cemented together. These are called clastic sedimentary rock.
What kind of rocks grapefruit sized thrown from a nearby volcano what are they called?
The rocks ejected from a volcano that are grapefruit-sized are typically called volcanic bombs. They are formed when molten lava is ejected into the air and solidifies before hitting the ground. Volcanic bombs can vary in size and shape depending on the type of eruption and the properties of the lava.
Grammar A volcano erupts the same like the science project you are doing for the science fair During your research you found out that the volcano?
it erupts the same as a full sized magma filled volcanoe therefore a both volcanoes erupted the same way
What type of volcano forms tuff pumice and pea sized pieces of basalt?
Cinder cone volcano forms tuff, pumice, and pea-sized pieces of basalt through explosive eruptions of gas-rich magma. These types of volcanoes have steep slopes and are typically composed of loose volcanic materials.
Is pumice small?
Not necessarily. Some chucks of pumice can be boulder sized.
Why does basalt have small sized crystals?
it cooled quick
What are the effects and cause of a supervolcanol?
A super volcano is a huge sized volcano that can erupt, the eruption will create crater sized holes around the eruption.
Does volcano ash have pebble sized particles?
No. Ash consists of sand sized particles and smaller. Pebble sized particles are called lapilli.
Is Mt Saint Helens a big sized volcano?
Yes.
If you find a grapefruit sized rock that appears to have flown through the air from a nearby volcano long ago. what kinds are rocks are they?
If you find a grapefruit-sized rock that has flown through the air from a volcano, it is likely a type of volcanic rock called a pyroclast or tephra. These rocks can include ash, pumice, or scoria, depending on their composition and the eruption's intensity. Pyroclastic materials are typically formed during explosive volcanic eruptions when magma is fragmented and ejected into the atmosphere. The specific characteristics of the rock, such as its texture and weight, can help determine its exact type.
How does a seamount form?
A seamount forms through volcanic activity, where magma rises from beneath the Earth's crust to create a mountain-like structure on the ocean floor. Over time, as the volcano becomes inactive and cools, it sinks below the ocean surface but remains as a seamount.
Is volcanic ash pebble-sized particles?
No. Pebble-sized particles from a volcano are called lapilli. Ash is sand-sized or smaller.

Do Volcanic Eruptions occur in predictable manner?
Not usually. It might be close to human prediction, but not very often. For example, take Pinatubo, in the Philippines. Everybodythought that they knew what was going to happen, but the volcano turned the tables. Eventually, everybody within a certain range of the volcano had to evacuate. Nobody ever thought that it would be so violent as to make it look like it was midnight instead of noon, nor did they expect good-sized chunks of pumice to hail down like rain.
What is pumice and what causes pumice to be light enough to float on water?
Pumice has an extremely low density due to its vesicular nature. Obsidian is not characteristically vesicular like pumice and its density is greater. Therefore, in equally sized samples pumice is lighter.
