They both depend on eruptions for their formation but lava tubes form only in large flows of low-viscosity, basaltic,lava. I don't know if this applies to Mt. Pinatubo.
it is referred to as lava when it is above ground, when below ground it is referred to as magma
Mount Mayon, Mount Pinatubo, and Mount Taal are all active volcanoes located in the Philippines, characterized by their potential for explosive eruptions. They are part of the Pacific Ring of Fire, which makes the region seismically and volcanically active. Each volcano has a history of significant eruptions that have impacted nearby communities and landscapes. Additionally, they are popular tourist destinations, drawing visitors for their scenic beauty and unique geological features.
No. Compared with other volcanoes of the same type, Mount Pinatubo is relatively small. Its 1991 eruption was very large, but by no means the largest. The 1815 eruption of Mont Tambora was more than 10 times larger.
YES
No. The fastest lava flows on earth have been recorded at Mount Nyiragongo in the Congo flowing at 60 mph (100 km/h). In most cases, however, lava flows very slowly. Blocky lava flows are the slowest, moving at speeds comparable to glaciers.
There are far too many to count here. Most volcanoes on convergent boundaries are stratovolcanoes. Well-known volcanoes on convergent boundaries include Mount St Helens, Mount Rainier, Mount Fuji, Mount Unzen, Mount Merapi, Krakatoa, Mount Tamboa, Mount Pinatubo, Mount Etna, Mount Vesuvius, Mount Pelee, Soufriere Hills, and Nevado Del Ruiz.
Geodes and caves are both hollow objects made of stone.
Mount Kilimanjaro is a dormant stratovolcano primarily composed of volcanic rock and does not erupt lava in the same manner as active volcanoes. It is primarily characterized by its volcanic materials rather than specific lava types like pahoehoe or aa. However, its past eruptions, which occurred thousands of years ago, produced both types of lava; pahoehoe is known for its smooth, ropy surface, while aa is rough and jagged. Overall, Kilimanjaro's volcanic history includes a variety of lava flows, but it is not currently an active erupting volcano.
no Caves are irregularly shaped, and are quite varied in their irregular shapes.
Same as in any caves of the same types anywhere in the world, which in karst caves is dissolution of the host limestone by weakly-acidic ground-water.
Both pillow lava and pahoehoe lava are types of basaltic lava that form during submarine volcanic eruptions. They both have smooth, ropy surfaces, caused by the flow of lava, and are relatively low in viscosity.
Lava om Mars is the same color as on Earth.
