Do besalt rock former inside or outside or earth?
Basalt rock forms inside the Earth, typically as a result of volcanic activity. Magma from the mantle rises to the surface through volcanic eruptions and cools rapidly to form basalt.
Is limestone formed from volcanic ash?
No, limestone is not formed from volcanic ash. Limestone is a sedimentary rock primarily composed of calcium carbonate that forms from the accumulation of organic remains, shells, and sometimes chemical precipitation in marine environments. Volcanic ash, on the other hand, is composed of fine volcanic rock particles ejected during volcanic eruptions.
What type of volcano forms tuff pumice and pea sized basalt?
The type of volcano that forms tuff, pumice, and pea-sized basalt is typically a stratovolcano or composite volcano. These volcanoes are characterized by explosive eruptions that eject volcanic ash, gas, and pyroclastic materials, which can result in the formation of tuff and pumice. The basalt fragments may come from more fluid lava flows associated with eruptions. Overall, the combination of explosive and effusive activity leads to the diverse volcanic materials found in these regions.
Does volcanic mountains build from layers of ash cinders and lava erupting onto the earth's surface?
Yes, volcanic mountains are formed from layers of ash, cinders, and lava that accumulate over time from volcanic eruptions. As lava cools and solidifies, it forms layers that build up to create the mountain. The repeated eruptions and accumulation of volcanic material contribute to the growth of the mountain over time.
What forms over hot spots?
Hot spots are areas of intense volcanic activity where magma rises from the mantle, creating a localized area of volcanic activity. As the magma rises, it can create volcanic eruptions, leading to the formation of lava flows, cinder cones, and volcanic islands over time.
What is the psychical weathering?
Physical weathering is any process that causes erosion. Volcanic eruptions, wind, precipitation and earthquakes are the most common forms.
What two geographical features form as a result of volcanic eruptions are in relation to plate tectonics?
It forms from the rise in mountains and valleys .:)

Volcanic ash, on the other hand, is composed of fine volcanic rock particles ejected during volcanic eruptions.
Is Basalt intrusive or extrusive?
extrusive it forms when lava from a volcanic eruption cools on the surface.
How does volcanic ash form?
Volcanic ash forms as a result of gas trapped in magma. As the magma approaches the surface and pressure drops, the gas is released and expands violently. The explosion blasts the magma into small particles, which become volcanic ash.
Does volcanic mountains build from layers of ash cinders and lava erupting onto the earth's surface?
Yes, volcanic mountains are formed from layers of ash, cinders, and lava that accumulate over time from volcanic eruptions. As lava cools and solidifies, it forms layers that build up to create the mountain. The repeated eruptions and accumulation of volcanic material contribute to the growth of the mountain over time.
Mineral that affects the thickness of magma?
The mineral quartz affects the thickness of magma by increasing its viscosity. When quartz-rich magma cools and solidifies, it forms a dense and viscous rock, like granite. This high viscosity can result in explosive volcanic eruptions.
What events cause a caldera?
A caldera forms as a result of and extremely large volcanic eruption. Such massive eruptions drain several to several hundred cubic kilometers of magma from underground. The land then collapses into the space left behind, leaving a depression called a caldera.
How do the volcanic mountains form?
Volcanic mountains form when molten rock (magma) erupts onto the Earth's surface through a vent or opening in the Earth's crust. This magma cools and hardens to form lava flows, layers of volcanic ash, and other volcanic materials that build up over time to create a mountain. Continued eruptions can further build up the size of the volcanic mountain.
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 forms over hot spots?
Hot spots are areas of intense volcanic activity where magma rises from the mantle, creating a localized area of volcanic activity. As the magma rises, it can create volcanic eruptions, leading to the formation of lava flows, cinder cones, and volcanic islands over time.
