Lava cant melt rocks.Rocks are the only thing that lava cant melt. (Well, not exactly.)
<><><><><>
Lava is melted rock. It is unlikely that lava alone, without an added heat source, could melt rocks. Its like melting ice - it requires more energy that you think it does to make that final state change. For example, water and ice in mixture at 32 degrees will not melt any further.

How fast is the lava of the volcano?
Depends on the type of volcano. Violent go's slow, and weak go's fast.
How fast does shield volcanoes lava flow?
Lava flows have been clocked at thirty kilometers per hour on the island of Hawaii. Lava usually travel at speeds of ten to three hundred meters per hour from shield volcanoes.
Which moves fast felsic lava or mafic lava?
A mafic lava flow will move faster than a felsic lava flow due to its lower viscosity. However, felsic magma tends to erupt explosively, producing fast-moving pyroclastic flows instead of lava flows.
How fast does lava and ash flow from kilauea?
Video of Krakatoa shows blocky lava flows. These flows are slow that you can barely see their movement if you can see it at all.
How fast does pillow lava flow?
Im not sure but I think its not fast but not slow so in the middle

What makes lava go fast and slow?
it depends on how steep the slope is.
How fast can lava flows travel on steep slopes?
Lava is slow only, 10 mph at fastest but hot ash can go 200 mph.
What is mafic lava like?
Fast moving-melted lava.
Which is fomed by fast cooling lava--pumice granite or basalt?
Pumice is the result of extremely fast cooling lava.
How fast does shield volcanoes lava flow?
Lava flows have been clocked at thirty kilometers per hour on the island of Hawaii. Lava usually travel at speeds of ten to three hundred meters per hour from shield volcanoes.
Hot fast moving lava?
The center of the earth is the hottest, and the crust is the furthest away from that heat.
How fast does dacite lava flow compared to mafic lava?
Dacite lava flows at speeds orders of magnitude slower than mafic lava.
What does lava that cools quickly form?
fast cooling lava -small crystals or no crystals
Which two igneous rocks are formed by fast cooled lava?
Obsidian and Pāhoehoe lava
What lava that cools quickly form?
fast cooling lava -small crystals or no crystals
Which moves fast felsic lava or mafic lava?
A mafic lava flow will move faster than a felsic lava flow due to its lower viscosity. However, felsic magma tends to erupt explosively, producing fast-moving pyroclastic flows instead of lava flows.
