Both pillow lava and pahoehoe lava have about the same composition and harden into a kind of rock called basalt.
pahoehoe is smooth and rope like sufaces. Aa is sharp and jaged last pillow lava is pressure billds up in side the lava untill it craks then it pours out forming yet another pillow on the last one.
Niether. Pahoehoe and a'a are both varieties of basaltic lava. The material from Pinatobo is of a dacitic composition, which is much more viscous than a'a or pahoehoe. It tends to erupt explosively, producing ash and pumice rather than lava flows. When dacitic lava does flow it creates a block lava flow.
No. Mount St Helens would produce block lava flows rather than pahhoehoe or a'a because of the high silica content. Currently there are no lava flows on that volcano but there is a lava dome made primarily of dacite.
Lava in mid-oceanic volcanoes is typically basaltic in composition. Basalt lava is relatively low in silica content and flows more easily compared to other types of lava. It often forms underwater pillow lava structures when it comes in contact with seawater.
A lava flow is basically a stream of lava on the surface. A lava tube is an underground cave through which lava flows downhill. A lava fountain is lava shooting into the air out of a volcano in much the same manner as a water fountain.
Pahoehoe or pillow lava - same thing
pahoehoe is smooth and rope like sufaces. Aa is sharp and jaged last pillow lava is pressure billds up in side the lava untill it craks then it pours out forming yet another pillow on the last one.
Pahoehoe is a type of lava flow that has a smooth, ropy texture. It is formed when low-viscosity basaltic lava flows and cools quickly, creating a distinctive wavy surface. Pahoehoe flows can be seen in volcanic regions and are a popular attraction for tourists.

Lava om Mars is the same color as on Earth.
No creatures live in lava, lava damages all mobs in the same way as normal people.
Magma and lava are like each other but magma is below the Earth and lava reaches the Earth's surface.
Not exactly. Molten rock is called either magma or lava depending on whether it is underground or above ground. When lava flows on the surface like a river or flood it is called a lava flows, but lava is not always flowing downhill. Sometimes it can collect in a pool called a lava lake, or be flung into the air in a lava fountain.
Magma; they are both the same substance, but lava has been exposed to the surface.
